Excuse me. Who knows how to raise green radish, cash cow, lucky hand, Brazilian keel and flowers in the photo?

The original growth condition of green radish is that there is no sunshine in the forest covered by towering trees. However, in the north of autumn and winter, in order to supplement the deficiency of temperature and photosynthesis, the illuminance should be increased. The method is to put the green radish in the best indoor light, or move to a sealed balcony to bask in the sun at noon. At the same time, when the temperature is low, try to open the window as little as possible, because in a very short time, the leaves may be frostbitten. The temperature is in the north, and the room temperature is above 10℃, so the green radish can survive the winter safely. When the room temperature is above 20℃, the green radish can grow normally. It is not a big problem for ordinary families to reach this temperature. It should be noted that the temperature difference is too large, and the leaves should not be close to the heating equipment. Humidity refers to the water content of air in the environment where plants grow. Under the condition of ensuring normal temperature, increasing humidity is extremely beneficial to plant growth. There are several ways to raise the temperature. Keep the plants close to the humidifier, which is turned on for more than 5 hours every day, so that the plants can enjoy the water mist sprayed by the humidifier; Spray water on leaves, stems and aerial roots of plants several times a day with a sprayer adjusted to fog level; Keep a proper amount of water in the flowerpot tray, and improve the local temperature of plants through evaporation of water; Wipe the leaves lightly with a cold wet towel or toilet paper or apply them lightly in a short time (65438+ 0-2 hours a day); Cover plants with transparent plastic film to create the effect of a small greenhouse, and evaporate water vapor in the soil for less than 2 hours every day to replenish water for plants. If the time is too long, it will affect the ventilation and photosynthesis of plants. The amount of watering in autumn and winter should be strictly controlled according to the room temperature. The temperature before heating is low, and the soil of plants evaporates slowly. Reduce watering, and the water quantity should be controlled between the original 1/4- 1/2. Even after heating, don't pour water too often, and pour less water into the basin. The water should seep through the brown silk. In addition, water should be sprayed on the aerial roots of the palm column to reduce the insufficient water absorption of the roots caused by excessive evaporation. The water poured in winter is better to bask in the sun for a day, and the water is too cold to damage the roots. In the fertile northern autumn and winter seasons, plants grow slowly or even stop growing, so it is necessary to reduce fertilization. Before winter, liquid inorganic fertilizer is mainly sprayed once every 15 days. Fertilization is mainly sprayed on the leaves after winter, mainly through the stomata on the leaves, and the fertilizer is absorbed through the stomata on the leaves, so the fertilizer effect can directly act on the leaves. Special fertilizer should be used for foliar fertilizer, and ordinary inorganic fertilizer is not easily absorbed by foliar. The flower protection series of Peking University and the flowers produced in Japan can be used as foliar fertilizer. Key points of cultivation: Raphanus sativus grows fast and its cultivation management is extensive. In the process of cultivation management, more water should be sprayed on the plants in summer, and fertilizer should be applied outside the roots every 10 day to keep the leaves green. Potted seedlings should be cut off when they grow out of the cultivation column 30cm; When the foot leaves fall off 30%-50%, it should be abandoned and replanted. Potted plants with green columns are ideal plants for courtyard doorposts and wall greening, and their leaves are also well arranged and matched. 4-5 plants are planted in each pot or directly cutted, and a brown column is arranged in the middle of the pot, which is convenient for the green radish to wind up and grow. Plastic pruning is carried out in spring. When the stems and vines are covered with brown columns and the tips are about 20 cm beyond the brown columns, cut off the stems and tips of 2-3 of them by 40 cm. When new buds and leaves germinate after short cutting, the shoot tips of other plants are cut off. For potted plants whose whole plants or lower leaves fall off due to freezing in winter or other reasons, the stems and vines can be cut by half 1/2, and the other half by 2/3 or 3/4, so that the height of the cuttings is staggered, and the new leaves of rice growing under the cuttings can be quickly covered with brown columns. [Edit this paragraph] The office and home maintenance method of Lvluo: 1. Green radish is transported from Guangzhou to all parts of the country in winter. Generally, green radish is frozen, so yellow leaves will appear quickly when placed indoors. These frozen leaves will be reissued after the Spring Festival. 2. Generally, the newly bought green radish has an adaptation period of about 1 month to the new environment, and the yellow leaves at the bottom are normal, but remember: yellow leaves or death. Thereby causing the upper leaves to turn yellow. 3, green radish is not afraid of black but a very dark environment can't be raised well! You can move the position regularly and adjust it to a place with good light; But you can't explode! 4, raising green radish should also be properly ventilated, 5, watering can wet the column, all of which are aerial roots. Spray some nitrogen fertilizer on the leaves from time to time and pour some ferrous sulfate diluent into the soil. 6. If the leaves are already yellow! It is not good to control too much or too little watering! At this time, put the green radish in a place with good ventilation and lighting! 7. The green radish is afraid that it will turn black when it is frozen to death. 8. When the green radish grows for a long time and climbs over the top of the column, it is ok to cut it off or turn its head upside down and let it climb down. Don't let it grow wildly. There are many reasons for the yellowing of the bottom leaves of radish: 1. Occasionally, it is normal metabolism during the growth period, but the interval is long. 2. Too much watering or drought; The water supply should be kept dry and moist. 3. Fertilization should be stopped after cooling in autumn. 4. Attention should be paid to indoor lighting and ventilation. 5. Spray water properly in winter. In addition, some green radish leaves are mostly because the roots are yellow, and the leaves are yellow only because the roots are rotten. The optimum temperature for the growth of cash cow is 20 ~ 32℃. Whether potted or planted underground, the annual average temperature changes little, so it is best to control the temperature for productive cultivation. Every summer, when the temperature is higher than 35℃, plants grow poorly. We should cover them with a black net to shade them and spray water on the surrounding environment to cool them down, so as to create a suitable and dry environment for them. It is best to keep the greenhouse temperature above 10℃ in winter. If the room temperature is lower than 5℃, it will easily lead to plant chilling injury and seriously endanger its survival. In late autumn and early winter, when the temperature drops below 8℃, it should be moved to a well-lit room in time, and the temperature should be kept between 8℃ and 10℃ during the whole wintering period, which is safer and more reliable. Light cash cows like light and have strong shade tolerance, so we should create a sunny but cool environment for them. Direct sunlight should be avoided, especially after a long rain in late spring and early summer. Bake in strong light for 5-6 hours around noon in summer, otherwise it will easily lead to burns of newly-picked leaves. In productive cultivation, it should be placed under a shade shed with a shade of 50-70% from late spring to Mid-Autumn Festival, but it should not be too dark, otherwise the newly picked leaves will be slender, yellow and the spacing between leaflets will be sparse, which will affect the compactness and aesthetics of the plants. In winter, the potted plants moved into the shed should be filled with light. The soil moisture in the basin is kept dry, and plants can be kept disease-free for many years. The newly extracted pinnate compound leaves did not show obvious phototaxis and the plant type was good. In order to protect potted cash cows, efforts should be made to create a humid and dry environment for them. In productive cultivation, plants placed in greenhouse should be sprayed with water once a day when the room temperature reaches above 33℃. Because plants are drought-tolerant, it is better to keep the soil slightly wet and dry, but occasionally watering too much water and fertilizer will not cause root rot. In winter, we should pay attention to spraying water on the blades and the surrounding environment, so that the relative humidity of the air can reach more than 50%. After the Mid-Autumn Festival, we should reduce watering, or spray water instead, and use the newly-picked leaves yesterday to spend the winter safely. In addition, special attention should be paid to the pot soil in winter, which should not be too wet, and it is better to be dry. Otherwise, under the condition of low temperature, the pot soil is too wet, which is more likely to lead to root rot or even the death of the whole plant. Due to the special climatic conditions of the origin of the money tree, the soil has formed a strong drought resistance, so the basic requirement for the cultivation substrate is good air permeability. The basic requirement of cultivation substrate is good permeability. Peat, coarse sand or washed cinder are mixed with a small amount of garden soil, and the PH value is adjusted to 6 ~ 6.5, which is slightly acidic. Because of its huge tuber, developed root system and long pinnate compound leaves, it is necessary to observe its growth in time during the growing season to decide whether to change pots and soil. Always maintain the permeability of the culture medium to create a good root environment for ventilation and water filtration. Check frequently in rainy season, and turn over the basin and change the soil in time when water is found in the basin. Fertilizer "cash cow" likes fertilizer. In addition to adding a proper amount of baked cake fertilizer or multi-element slow-release compound fertilizer to the cultivation substrate, the mixed solution of 0. 1% urea and 0. 1% potassium dihydrogen phosphate can be applied 2-3 times a month in the growing season, or 20- 10-20(20-20-20). After the Mid-Autumn Festival, in order to make it overwinter safely, nitrogen fertilizer should be stopped and 0.3% potassium dihydrogen phosphate solution should be applied for 2 ~ 3 times continuously to promote the hardening and enrichment of young leaf shafts and newly-pumped leaves. When the temperature drops below 15℃, all forms of topdressing should be stopped to avoid fertilizer damage and root damage under low temperature. [2] Control score 1. Freezing injury When the temperature drops below 5℃ in winter, when the soil in the basin is wet, it is easy to cause the feathery young leaves of plants to fall off due to freezing injury, and in severe cases, it will cause tuber rot and it is difficult to restore vitality. Prevention and control methods: whether it is productive cultivation, quasi-cultivation or family feeding, the greenhouse temperature should be kept not lower than 10℃ during the winter, and the basin soil should be kept in a slightly dry state. A few potted plants can be covered with double plastic bags at night on particularly cold days, and the bagging can be removed after the temperature rises the next day. 2. Burning in hot summer, or a sunny day after a long rain in Chu Qing, or being kept indoors for a long time and just moved outdoors for restorative maintenance, and directly exposed to the sun, it is easy to cause the fat and tender leaves to be burned, leading to partial loss of green and white leaves, or the whole leaves to be burned, and the necrotic parts in the later stage become brown and black. Prevention and control methods: after entering summer, move the plants to a semi-cool environment in time. If it rains for a long time in late spring and early summer, you should listen to the weather forecast in time and shade the potted plants as soon as possible. 3. Brown spot disease This disease mostly occurs on leaves, and the lesion is nearly round, taupe to yellowish brown, and the edge color is slightly darker. The disease is easy to occur under the conditions of high temperature and humidity and poor ventilation. Prevention and control methods: If a small number of diseased leaves are found, they should be removed and destroyed in time. At the initial stage of the disease, 600-fold solution of 50% carbendazim wettable powder or 500-fold solution of 40% chlorothalonil suspension/kloc-0 was sprayed on the leaves every 10 day for 3 ~ 4 times continuously, and the control effect was good. 4. In the environment with poor ventilation and poor lighting, the leaves of cash cow are vulnerable to the sucking of scale insects. Prevention and control methods: a small number of domestic feeding, can be used to stick the insect body with transparent tape or wipe off the live insect body with wet cloth. In productive cultivation, 20% chlorpyrifos wettable powder 1000 times can be sprayed at the peak of nymph hatching, which has good insecticidal effect. Lucky tree scientific name Malabaris: Pachira macrocarpa Cuttings Lucky tree alias: Fortune tree, Cucurbitaceae, Central American genus: Kapok family, Cucurbitaceae English name: Malabar Chestnut Classification: Malabaris, Kapok family origin: Mexican planting time: small file: evergreen bridge tree (deciduous phenomenon in winter in northern Taiwan Province Province). Palmately compound leaves, oblong to obovate, smooth and hairless. Flowers are large and beautiful, solitary in leaf axils, white, with linear petals and slender filaments. Woody fruit. The seeds are covered with fleshy tissue. Usage: Pepper and potted seeds of roadside trees are fried, such as peanut trunk paste seeds, which can be canned. Malabari's scientific name is Pachira macrocarpa. The plant information and morphological characteristics are evergreen trees, with a height of 8~ 15m, palmately compound leaves, 5~7 leaflets and many alternate branches. The flowers are large, 22.5 cm long, with split petals, red, white or light yellow in color and gorgeous in color. It blooms from April to May, matures in September to 65438+1October, and 10~20 grains are large, irregular and light brown. The distribution of origin originated in Mexico and is now cultivated in all tropical areas of the world. Introduced into China in 1950s, it gradually developed from oil crops to greening and indoor foliage plants. Growth habits like high temperature and high humidity climate, poor cold resistance, seedlings avoid frost, adult trees can withstand light frost and long-term low temperature of 5 ~ 6c, South China can overwinter in the open air, and northern areas must move into greenhouses in winter, and they like fertile, loose, breathable and water-retaining sandy loam, acid soil, alkaline soil or cohesive soil, which is more resistant to water and humidity and slightly dry. Breeding is mainly based on seed propagation. Seeds mature in autumn, so they should be picked and sown. The seed coat is fragile and easy to absorb water. Before sowing, the seeds can be soaked in warm water at 30 ~ 35℃ for 24 hours, and then sown on the seedbed or directly in the seedling bag. The germination temperature of seeds should be above 15C, and it will start to germinate after 5 days. When the seedlings grow faster, they can be planted in the seedbed for about 1 month and then transplanted into the seedling bag to continue cultivation. When the seedlings grow to 20 ~ 3Ocm, they can be moved to the ground or transferred to a larger seedling bag to cultivate large seedlings. The stem base of seedlings is swollen, so seeds are used for propagation, and stems, branches or leaves (with petioles) can also be used for cutting, but the stem base of cutting seedlings is often not swollen, so it is rarely used. Ornamental application has beautiful plant shape, thick rhizome, green stems and leaves all year round, soft branches, which can be woven and shaped, and the old branches germinate quickly. Because it can produce more new dry wood after logging, it has also become a rich tree. This kind of tree is often chosen for business, factory opening and decoration for good luck. Tree is a kind of high-piled foliage plant, which is mostly placed on both sides of the gate and in the corner of the hall. It is a popular ornamental plant in the north and south in recent years. The maintenance of pests and diseases and indoor viewing are mostly potted with piles. In order to accelerate growth, you can plant it first and then plant it in a pot. The well-drained sandy soil should be selected for ground planting, with the plant spacing of 30X5Ocm and the local seedlings reaching about 80 cm. Dig up, braid 3-5 plants, continue to cultivate, cut dry according to 80- 15 ocm after molding, and put in a basin for about 2 months to get the finished product. It can also be cultivated in a large seedling bag of 80 cm on the left, and then cultivated in a whip shape. Pile-making is a highly technical job. At present, the domestic pile-making level is not up to standard, and the product quality is not as good as that of Taiwan Province Province, so it is necessary to strengthen exploration. Or you can plant it on the ground until the stem reaches 8~ 1Ocm, and plant three high and low piles on the pot, or you can turn it into a beautiful potted plant with piles. Malabali is very adaptable to the environment, and it will thrive with sufficient fertilizer and water. It is fertilized once a month during the growing season to keep enough water, which can shade the leaves by 50% to make them light green. As long as it is not lower than ZC in winter, it can be safely wintered, but frost areas should be covered with film or put in greenhouses to prevent frost. This genus is vulnerable to sugarcane borer, which is a quarantine pest. Introduced into China in recent years, larvae corrode phloem and cause death. Drop omethoate to kill insects when you find insect eyes, or burn them in time. Malabali can be used for indoor viewing for a long time. If the branches are too long, they should be pruned vigorously. After a period of time, you can continue to watch the new branches. Brazilian keel Brazilian keel column, alias keel. Euphorbiaceae, Euphorbia. The plant is triangular, multi-branched, blue-green, 4 to 5 meters high, with small thorns on the edge, which is extremely short. Dragon bone column has white flowers in summer, 4-9, clustered at the base of thorns, which are open at day and closed at night (potted plants are generally not easy to bloom), and the berries are small and round, blue-purple and edible. Cutting is often used for propagation, and the keel is a succulent plant. When cutting, the pulp will flow out and can be sealed with plant ash. Leave it in the shade for 7 days to 10 days, and then cut it after the plant shrinks. One is to cut the keel into sections, and the upper and lower incisions are closed with plant ash, and the cutting length is 20 cm to 25 cm. The other is branches taken from keel branches, which can be cut after drying, but they are too small and tender to take root. This kind of cutting only has a small wound at the root, and the cutting takes root quickly. The matrix for cutting the keel needs vermiculite, pearl powder particles, pure river sand and no soil. Single-plant cutting or multi-plant centralized cutting can be carried out. After cutting, water is poured, only to the cutting place, where there is plenty of sunshine. Water as little as possible during rooting, don't dry it, and wait for 30 to 40 days to take root. Transplanting after rooting, the pot soil needs to be evenly mixed with 1/2 river sand and 1/2 loam soil, then planting, pouring 2% potassium permanganate water, not only disinfecting the soil, but also watering the soil. Tall plants can be tied and fixed with sticks. When cultivated in sunny places, it is still necessary to control the amount of water, which should be dry and not wet. There are many kinds of dragon bone columns, such as cluster, three columns and nine columns. The author thinks that nine columns and twelve columns are spectacular. The specific shaping method is as follows: When the nine-column plant grows to 20 cm to 30 cm, cut off the top with a sharp knife and seal it with plant ash immediately. After the plant grows branches, only the top three branches are left, one at each corner, and the rest are erased. When the second layer grows to 25 cm to 30 cm, the top is cut off again. After the branches are born, choose three branches, three at each corner, that is, 1, 3, 9-shaped keel. The angle selection method of twelve columns is the same as above, except that when the length of nine columns is 20 cm to 30 cm, the top is cut off, and then three branches are cultured, and each angle is selected as 1 or 3. Other twigs are erased with the increase of length, keeping the tree shape consistent. When the tufted columnar plants grow to 40 cm to 50 cm or 30 cm to 40 cm, cut off the top and let them grow naturally to form a multi-headed keel, but the selection should be orderly and not disorderly. When the growth height of the dragon bone column reaches 2 meters to 3 meters, many branches are formed, which is easy to cause top-heavy and unstable, and should be fixed with wooden sticks in time. Dragon bone column needs plenty of sunshine, the branches are blue-green, the leaves are like fish scales, and they will glow under the sunlight, with many bodies and sharp swords. Very spectacular, it is a good potted flower. Longguzhu is not cold-tolerant, but drought-tolerant, and likes dry loam. It should be kept indoors in winter in the north, planted in the open field in the south, or used as a fence, which is not only a green barrier, but also beautifies the courtyard, and flowers and fruits can be seen in summer. Dragon bone column is known as "universal rootstock", which can be grafted with Rosa davurica and Crab claw orchid, and it is colorful. Dragon bone column has few pests and poor indoor ventilation, which is easy to be harmed by red spider. It is found that the top of the branch is reddish brown with mesh, and it can be sprayed with omethoate 1000 ~ 2000 times, and the dosage should not be too large to prevent the head from festering. Yemen iron Category: Tequila Subclass: Dracaena Chinese Name: yemen iron Latin: Main points of Dracaena cultivation: The cultivation medium is fertile loam or rotten soil, and the drainage is good. 50-60% shading is the best illumination, and direct glare is not allowed. Indoor cultivation should be placed in a well-lit place. Insufficient light will make the leaves fade, and the leaves are slender and wavy. Fertilization can use organic fertilizer, such as rotten peanut bran or human feces as fertilizer, and can be combined with ternary foliar fertilizer, 3-4 times a month. Sex likes high temperature and high humidity, and the suitable growth temperature is 20-30℃. Winter in 10℃ should pay attention to cold protection measures, to prevent freezing damage to dry up the leaves. Pay attention to ventilation and keep the relative humidity of air above 80%. Changing pots and plastic pipes every spring is the best time to change pots. When the plant shape is large enough, it is advisable to change the big pot to make the roots have more room for growth. Dracaena plants are resistant to pruning. As long as the top or upper branches are cut off, the buds below the incision will germinate and grow into new branches, which can grow 1-5 buds at the same time, enriching the crown width, making the plant shape more symmetrical and increasing the beauty of the plant shape. Many growers often cut off the tops when the plants grow to 1 m high. After half a year to a year, the price of plants can be increased by 3-4 times, which is a typical flower deep processing process. Propagation is mainly based on tissue culture, and cutting propagation can also be used. The seedlings cultivated by tissue culture and propagation are neat and stable. The common phenomena of pest control are dead leaves and scorched edges, which are physiological diseases caused by too dry air, too irregular watering and fertilization or too low temperature after drought. Only by strengthening daily management can we overcome them. Maintain a warm, humid and well-ventilated environment in yemen iron. The optimum growth temperature is 20-30℃, and when it is lower than 10℃ in winter, adverse reactions will occur. I like semi-shade and can tolerate shade, but long-term maintenance in the shade is not conducive to plant health. It is best to put it in a bright and scattered place, avoid direct sunlight in summer, and avoid the leaves from being burned by the sun and turning yellow or white. If there is too little light, the leaves will be gray-green, and the brightness will be insufficient, and the basal leaves will turn yellow, especially for striped varieties. Under the condition of low light for a long time, the color will become lighter or disappear, thus losing its ornamental value. Yemen's iron mines have little demand for water. Generally, it is advisable to water until it is dry and wet. The interval is uncertain, but it has certain rules in a constant environment, but it needs personal experience. In addition, the water quality should be kept clean and fertilization should be combined with watering. Generally, water-soluble fertilizer or decomposed cake fertilizer should be used, and fertilizer can be supplemented every time watering during the vigorous growth period; But don't add fertilizer or less fertilizer when watering when the growth is slow. Fertilization is mainly based on ternary compound fertilizer of nitrogen, phosphorus and potassium, and one element is not suitable for single application. You can also spray foliar fertilizer outside the roots, such as spraying 0. 1-0.2% urea and potassium dihydrogen phosphate solution every half month. Usually keep the leaves clean, and don't let too much dust stay on the leaves, which is unsightly and easy to get sick. When the iron in the leaf gate grows too high, only the lower leaves are left, which can be shortened according to the viewing angle, and the upper branches after pruning can be cut into river sand or vermiculite for cultivation and rooting into new plants. Since there are no leaves to evaporate water, the branches below should be watered less or less, and kept in the semi-sunny or sunny place. After the leaf buds grow, nitrogen fertilizer should be combined with watering to promote the growth of leaves. The plants grown by pruning are not only beautiful in appearance, but also plump and beautiful.
