The ecological habits of Cymbidium japonicum

Cymbidium japonicum was born in a well-drained and stony place under the forest or in rock crevices, with an altitude of 9-16 meters.

cultivation techniques of cymbidium japonicum

Orchard shed and orchid house should be located with the west facing the east, which is empty in the southeast and has high walls or trees in the west. You can see Chu Yang and keep out the scorching sun. A courtyard with clean air and a certain humidity guarantee in the surrounding environment. Pay attention to ventilation, exposure, avoiding the hot sun, avoiding smoking, etc. If it is built on the roof or balcony of the floor, in addition to shading it, the curtain should be hung in the northwest direction to prevent the grass leaves from being burned by the oblique setting sun in the afternoon. It is best to use mud or clear water pool under the orchid shed to keep the air around the orchid shed moist.

and pay attention to the ground cleaning to prevent the breeding of pests and diseases. When the outdoor temperature drops to about ℃, the orchid basin must be moved indoors to prevent frostbite of the orchid root. If the weather is fine in winter, the temperature in the blue room can exceed 15℃, but the room temperature drops in rainy and snowy weather. At this time, the room temperature should be kept at 15℃ by heating and lighting. There is no need to heat at night, just keep it at 5℃. Heating can be carried out in late autumn and early winter, in order to promote the full maturity of new plants in that year.

However, from mid-December to the end of January, it is not necessary to heat it, and it is enough to keep the room temperature not lower than 5℃, leaving its vegetative growth in a very slow state. Since February, humidification, heating and sufficient illumination have enabled orchids to enter the growth period ahead of schedule. After heating, the new buds germinate ahead of time, and the new buds are usually unearthed after 45 days of heating. After another 9 days, the plant can be grown. By the middle of June, the second new shoots were unearthed, thus achieving the effect of two batches of new seedlings in one year. When heating in winter, we should pay attention to the need to add light, but we must not keep heating for 24 hours so that there is no temperature difference.

in addition, the heating should not be too high, and it will be harmful and useless if it exceeds 25℃. Generally, the time to put the pots into the pots (or turn them over) is from March to April in spring or from October to November in autumn. The flowerpot with small mouth, deep pot and large bottom hole is better. Newly dug wild seedlings from the mountains need to be planted in earthen pots (clay pots), so that the orchid mud is easy to dry, has good ventilation and is easy to root; 2-3 years later, the purple sand basin or porcelain basin can be replaced.

The method of planting orchids (in pots) is different from that of ordinary flowers, especially famous orchids, and the roots must be washed when they are turned over and moved to pots. Methods Immerse the roots in clean water and gently wash them with an old toothbrush or writing brush. Do not use too much force to hurt the roots. Cut off the residual leaves, yellow leaves, broken roots and black rotten roots with scissors, and be careful not to hurt the buds.

then put the treated plants in a cool and ventilated place to dry, and then plant them in a pot when the roots are white and show fine wrinkles and softness. Method 1: After preparing the potted plants and planting materials, put the potted plants upside down (with roots above and leaves below) under the tap and rinse them with slow water, but the water pressure should not be too strong to avoid damaging the potted plants and leaves. Grasp the blue head with thumb and forefinger, hold the little finger against the edge of the basin, and fix the root with bamboo chopsticks. When putting it into the basin, try not to let the root touch the basin wall. Pour the mixed gravel with the size of beans into the bottom of the basin to one third.

then pour the medium-sized plant material to about five places, fill it and try not to leave any space. Pull out the bamboo chopsticks and shake the plant material in the pot. After filling the plant material, scoop it in with large plant material to a distance of 1.5 cm from the basin edge. Finally, pour in the bean seeds, so as to completely bury pseudobulb in the soil, and then fully shake it. Gently press the planting material with a soil compaction tool and smooth the surface. After planting, it is better to plant the material in the pot with the center slightly higher. Method 2: Pay attention to the drainage of the basin bottom, fill the clay basin with broken tiles, and cover the basin bottom with perforated nylon yarn for purple sand basin.

before planting, spread coarse stones in the basin, accounting for about 2/5 of the depth of the basin. The coarse stone culture soil is 3-5 cm thick, and then add bluegrass. Pay attention to the root of the basin to spread itself and not curl. When planting famous bluegrass, we must put the old grass aside and the new grass in the center, so that there is room for new grass. When planting, hold the bluegrass in your left hand, add mud in your right hand (to prevent the mud from penetrating into the leaf heart), and then lift the bluegrass slightly to make the roots stretch naturally. Then shake the basin while adding soil, so that the soil is in close contact with the roots. Then press the soil around the stem tightly by hand, and finally make the basin surface slightly steamed (that is, slightly lower around the middle).

cover it with a layer of moss or fine stones, so that the basin soil is not easy to harden and can reduce water evaporation. Water the basin immediately after serving it. The first watering should be sufficient. Finally, place the basin in the shade. It is not suitable to bask in the sun directly for one month, and water should be controlled, and it should not be too wet. In the future, the location should be chosen in a place where it is semi-cloudy and semi-sunny, ventilated and ventilated, and shines in the sun in the morning.

watering is in the peak period of orchid growth, and once there is water shortage in summer, potted orchids will not grow well, and orchids need to be eight parts dry and two parts wet. Watering should be based on the principle of "watering when it is dry, stopping when it is wet, and being moderately dry". Water must be thoroughly watered, not half watered. The watering times may depend on the planting materials of potted orchids. Hard and hydrophobic plants such as volcanic rocks, red bricks and pumice can supply water once a day; Pond mud, humus soil and other plants with strong water absorption can supply water once every two or three days. Watering is generally done in the early morning or evening, and it is forbidden to water and pour at noon.

it is better to use clean, pollution-free and slightly acidic water (pH 5.5-6.5). Orchid roots rot, black spots appear on the leaves, and leaf buds rot, which are mostly related to improper water supply. After planting flowers and plants, the first watering is called "root-fixing water". Rooting water must be poured thoroughly. Generally, it should be watered twice continuously after the basin is put on. After the first watering, it should be watered again after the water flows out from the hole at the bottom of the basin.

choose an appropriate watering method. Usually, the spraying method is used, which can not only increase the air humidity, but also wash the dust on the leaves. However, for flowers with fluffy leaves or blooming flowers, it is not advisable to spray them. Instead, the whole flowerpot should be placed in a water basin, so that the water does not flood the mouth of the basin, and the soil of the basin should be moistened by using the holes at the bottom of the basin. Pay attention to the water temperature.

If there is a big difference between the water temperature and the soil temperature (more than 6℃), put the water indoors for a period of time in winter, or add a little warm water to make the water temperature rise to about 15℃ before watering the flowers; In summer, you should avoid watering in the hot sun and at high temperature at noon. Watering time. In spring, autumn and winter, around 1 am and after 4 pm are the most suitable time to water flowers. Fertilizing farmyard manure is a good organic fertilizer, but it must be stacked and decomposed for more than one year before it can be used. This fertilizer solution can be used to pour water 1-2 times, and it should be applied at the edge of the basin as far as possible, without touching the roots or touching the orchid leaves.

When applying chemical fertilizer, attention should be paid to the balance of nitrogen, phosphorus and potassium, and the concentration should be strictly controlled. Leaf art seedlings should control the synthesis of chlorophyll, and it is not suitable to apply nitrogen fertilizer, nor fertilizers containing manganese and magnesium (such as calcium magnesium phosphate, etc.), because manganese and magnesium can accelerate the synthesis of chlorophyll.

foliar spraying is the main method. Foliar spraying can supplement the nutrition of orchid plants through the absorption of orchid leaves, without causing fertilizer damage to roots, which is the best fertilization method for orchids. As long as you spray fertilizer on the leaves for about 1 days during the growth and development period, you can completely raise orchids without fertilizing the pots.

potassium dihydrogen phosphate with a ratio of 1∶1 and boron fertilizer with a ratio of 1∶1 can be used, and aloe liquid can also be used. Because aloe contains a lot of nutrients such as polysaccharides and amino acids, and contains more than 2 kinds of minerals, it can meet the nutrients needed by orchids, and aloe tincture can kill almost all germs and viruses, so there is no need to apply pesticides to prevent diseases after application. Apply fertilizer sparingly, eat less and eat more meals: orchids don't need much fertilizer during the growth period. For vigorous orchids, apply thin liquid fertilizer every 1-15 days.

mainly natural organic matter. Natural organic fertilizer has comprehensive nutrients, no need to apply other fertilizers, and it is gentle in temperament and has no side effects on plants. However, chemical fertilizers are easy to harden the substrate, and most of them are acidic, which will cause the substrate to be too acidic and cause diseases for a long time.

propagation mode of cymbidium japonicum

ramet propagation can be carried out in spring and autumn, usually every three years. All plants with strong growth and dense pseudobulbs can be divided into plants, and at least 5 connected pseudobulbs should be preserved in each cluster after division. Before branching, reduce irrigation, so that the soil in the basin is smaller than that in the pot. When the plants are planted in the basin, first cover the hole at the bottom of the basin with broken tiles, then spread coarse stones, accounting for 1/5 to 1/4 of the depth of the basin, then put coarse soil and a small amount of fine soil, and then plant with sandy loam rich in humus.

The planting depth should be such that the pseudobulb is just buried in the soil, and the edge of the pot should be 2 cm along the mouth, covered with Cuiyuncao or fine stones, and finally watered and placed in the shade for 1-15 days, so as to keep the soil moist, gradually reduce watering and carry out normal maintenance. Orchid seeds are very fine, and there is only one immature embryo in the seed, so the germination ability is very low. In addition, the seed coat is not easy to absorb water, so it can't germinate by conventional sowing methods. Therefore, it is necessary to supply nutrients with orchids or artificial culture medium to germinate.

It is best to choose the fruit that has not cracked for sowing. After the surface is sterilized with 75% alcohol, take out the seeds, soak them in 1% sodium hypochlorite for 5-1 minutes, take them out and rinse them with sterile water for 3 times, then sow them in a culture bottle with culture medium, then put them in a dark culture room, keep the temperature at about 25C, and then move them to light after germination to form protocorms. It takes six months to a year from sowing to transplanting. Tissue culture has been successful, and this method can be used to breed where conditions permit.

disease control of cymbidium japonicum

disease control of white silk disease mostly occurs in the rainy season. At the beginning of the disease, the leaf base is covered with white hyphae, which leads to root rot.

control method: remove the soil in the basin with bacteria and sprinkle with quintozene powder or lime. Radical treatment: pay attention to ventilation and light transmission, and the basin soil is well drained. Serious diseased plants will be burned. Anthrax is found all year round, especially in hot and rainy seasons, especially in Cymbidium sinense. The lesion first extends from the tip of the leaf to the rhizome, which is brown at first, then gradually expands and increases, and many dry black spots appear, which leads to the death of the whole plant in severe cases.

prevention and treatment methods: in addition to actively improving environmental conditions, during the onset period, 5% thiophanate methyl wettable powder can be sprayed with 8-15 times solution once every 7-1 days; Then it is supplemented with 1% equal Bordeaux mixture, once every half month, and sprayed continuously for 3-5 times.

pest control scale insects are commonly known as "blue lice". In the case of high temperature and humidity and poor air flow, the reproduction is the fastest. It can be sprayed with 1% omethoate or 15 times 5% mala sulfur during the incubation period. If the number of pots is small, it can also be brushed off manually.

Distribution area of Cymbidium adenophorum

Cymbidium adenophorum is produced in China, Guangdong, Hainan, southwestern Guangxi, southwestern Guizhou and southeastern Yunnan (Mengzi, Yanshan, Malipo and Pingbian). Nepal, Bhutan, India, Myanmar, Thailand, Vietnam, Cambodia and the Philippines are also distributed. The type specimens of Cymbidium adenophorum were collected from Bhutan.

the cultural background of cymbidium japonicum

Orchid is one of the oldest flowers in China, and there was a legend of planting orchids as early as the time of Emperor Yao. The ancients thought that orchids had three beauties, namely, fragrance, flowers and leaves, and four beauties, namely, clear breath, clear color, clear spirit and clear rhyme, which were "the beauty of ideals and the magic of everything". Confucius was the first to endow orchids with a certain humanistic spirit. According to Qin Cao written by Cai Yong in the Eastern Han Dynasty, Confucius defended himself against Lu, and when he saw the secluded orchid in the valley, he sighed, "Orchids should be the king's fragrance." The real orchid culture originated from Qu Yuan, a patriotic poet of Chu State in the Warring States Period. He planted orchids, loved orchids and chanted orchids, and relied on orchids to influence future generations for thousands of years. Later poets in
