Spring is the vigorous growth period of flowers, and it is also the golden period of orchid flowering, germination and growth. So? Let me tell you!

First, spring orchids.

It is very important to water orchids in spring, which should be carried out according to climate change, habits and growth process of different orchids. In early spring, the temperature is still very low, some varieties are still in dormancy, water evaporation is slow, and water demand is very small. Only when the planting materials are dry can you water them properly. For the soon-to-be-opened cymbidium, water more, water less during flowering to extend the flowering period, and stop watering a few days after flowering. However, this depends on the degree of wetting of the substrate. Since then, when the spring breeze blows and the weather turns warmer, it happens to be the time when the new buds are expanded and unearthed. At this time, due to the rapid evaporation of water in the basin soil, water should be replenished in time. The number of watering times and the amount of water should be increased accordingly, but the pot soil should not be too wet, and the air humidity should be kept between 40% and 50%, so as not to cause rotten roots and buds. Orchids should be planted with granular plants, which can be moistened a little. When the temperature rises above 20 degrees or the weather is dry, you can spray water or water the orchid plants to keep them moist. For flowering orchids, it is best not to spray water, and the soil in the basin should be dry to prevent the petals of orchids from lengthening. This is also the way that predecessors taught that spring is afraid of dripping water and spring must be moistened. When the weather gets warmer, after the orchids leave the house, they should be watered once to remove the waste gas and waste in the plants and pots and keep them moist, so that the orchids can recover quickly. Similarly, spring rain is as expensive as oil. If it is properly drenched on bluegrass, orchids can sprout like mushrooms after rain. Water more when sprouting, less after sprouting, more when flower buds appear, less when flowering to prolong the flowering period, stop watering for a few days after flowers wither, and let them sleep before watering.

In a word, spring is the golden opportunity for orchids to germinate and grow. The watering management of orchids should grasp a transparent word and highlight a moist word, so that orchids can quickly recover their vitality, new buds grow sturdily and flowers bloom like a scene.

Second, fertilization of orchids in spring.

Spring is the season when orchids germinate and grow, so it is necessary to supplement fertilizers to better sprout and grow seedlings. There are three aspects to be grasped in fertilization of orchids in spring: First, we should pay attention to comprehensiveness. Nitrogen fertilizer can be applied less once or twice in the early stage, and phosphorus and potassium fertilizer can be applied less many times in the later stage. Nitrogen fertilizer can accelerate the germination of orchids, and "phosphorus and potassium" fertilizer can promote the rooting after germination! It is a nutritional supplement for flowering bluegrass, and can also promote flower bud differentiation of four seasons bluegrass flowers that bloom in summer. Second, we should pay attention to sparse characters. Adhere to the principle of thin fertilizer and diligent application. Because it is also the time for new roots to sprout and stretch during the germination and leaf exhibition period. If concentrated fertilizer is applied, it is easy to damage buds and roots, affect the normal growth of plants and even cause plant death. Third, pay attention to the temperature. In early spring, the temperature is below 15℃, which is generally not suitable for fertilization. When the temperature rises to 15-20℃, comprehensive fertilization can be carried out. Nitrogen fertilizer is the main fertilizer, and phosphorus and potassium are used together, generally l times every half month. 0. 1%-0.2% potassium dihydrogen phosphate can also be used to spray fertilizer on leaves to promote rooting and germination and cultivate strong seedlings.

Third, the orchid light in spring.

In spring, orchid seedlings have entered the germination period. Good light can make orchid seedlings effectively accumulate energy, moisten reed heads and grow new buds. Very necessary. Orchids should be moved to sunny places as far as possible, whether indoors or outdoors. In sunny and warm weather, you can also move the orchid basin to the outdoor leeward and sunny place to receive sunlight, which can not only carry out photosynthesis, but also warm the orchid plants. But the time must be after 10 am and before 4pm. Pay special attention not to leave the orchid pot outdoors for the night, which will be attacked by frost and cold wind. On the other hand, Ye Yilan can only receive short-term light to prevent the deterioration of Ye Yi. In spring, when the temperature is below 28℃, orchids generally do not shade. Unless the temperature is too high at the end of spring and reaches about 30℃, it should be shaded properly at noon to prevent the seedlings from being burned by high temperature. In addition, when the light in the sky blue room is insufficient in rainy days, it is best to use plant lamps or incandescent lamps to fill the light.

Fourth, bluegrass keeps warm in spring.

According to predecessors' theories of spring covering, autumn freezing and spring climate change, orchids must be kept warm to ensure their survival and growth. Covering in spring can make Poa pratensis adapt to the coming high temperature in summer, and make it enter the vegetative growth period ahead of time, and sprout new buds ahead of time, thus improving the seedling rate of the year. The optimum temperature for the vegetative growth of Poa pratensis is 15℃-25℃. In spring, we should also pay attention to expanding the temperature difference between day and night of orchids, and make up the temperature when the temperature is below 20℃ during the day. The temperature at night can be controlled within the range of 5℃-65438 05℃. The low temperature at night reduces the nutrient consumption of Poa pratensis, which is beneficial to the storage of nutrients made by Poa pratensis during the day and promotes more seedlings and better seedlings. Occasionally it snows or rains, and there is a cold current. Be sure to close the doors and windows to prevent the invasion of cold air. If freezing occurs outdoors and the room temperature drops below 5 degrees Celsius, we must find ways to raise the temperature above 0 degrees Celsius. Orchid plants that overwinter or are placed outdoors should be covered with double-layer plastic films in rainy, snowy and nighttime to prevent frostbite.

Fifth, bluegrass turns the pot in spring.

Generally, the traditional basin turning season should be at the vernal equinox or autumnal equinox, and the north should be after the vernal equinox or before the autumnal equinox. The first half of the year is best to come in Grain Rain at the vernal equinox. At this time, the flowering period has passed, and the leaf buds have not yet germinated, so it is not easy to be frozen. It is the best time to divide the pots of bluegrass. Grasping the opportunity of potted bluegrass is an important part of turning over the pots to raise bluegrass. Turning the pan must be done purposefully according to the blue situation. Try not to turn the pages. This can reduce the unfavorable factors caused by pot turning, which is beneficial to the rejuvenation and rapid growth of bluegrass. Turn the basin scientifically. Turning the pot seems simple, but it is also very scientific. According to the objective habits and requirements of bluegrass growth, the pots can be turned over to raise grass. If you don't follow their habits and requirements, you won't turn over the pot at will, and bluegrass will suffer. Therefore, we should make great efforts to turn over the land and plant it seriously with the guiding ideology of seven points planting and three points in charge. Pay attention to the following items when operating:

1. There are three ways to turn the basin:

1 Run: Run the basin and soil;

(2) Proper inter-seedling: The key to cultivate Poa pratensis is the ventilation of soil inter-seedling, ventilation of root inter-seedling, Qing Ye withering and inter-seedling.

③ Appropriate shade: go to the basin on cloudy days and keep it in the shade for half a month to relieve the pain of not eating human fireworks.

2. Disinfect when turning over pots: tools, pots, orchids and the environment must be strictly disinfected and sterilized. This is the focus of the pot turning work.

3. Pay attention to the maintenance of new grass and weak grass after turning over the pot: clear tillage, dry tillage, shady tillage, accompanying tillage and weak wind tillage.

4. Other considerations:

(1) The soil used for turning pots should be kept moist and fertile.

② No root fertilizer was applied after turning over the pots,

③ Root cutting treatment. The root is broken, the central column is not reinforced, and the rotten root is not rotten. Just peel off the rotten part. After peeling off the rotten part, look at the tendons. After the tendon turns black and is cut off, the white tendon still has the function of absorbing and transporting water and nutrients, which can be preserved.

(4) Don't let the substrate containing base fertilizer near the wound of orchid plants to prevent the wound from festering.

⑤ Yin and Yang placement: The placement of bluegrass should be handled according to your own habits. Generally speaking, bluegrass such as Su Xin Cao, lotus petals, daffodils and artistic grass flowers should be born in the shade, while plum petals, exotic flowers and herbs should be born in the sun. When the petal shape and plant type are the same, downhill grass is more suitable than traditional grass; Strong and clumpy grass is more suitable for sunshine than weak seedlings. Therefore, the positioning of bluegrass can be selected.

In a word, turning over the pot of bluegrass is an important and complicated skill to protect orchids. You can't turn over the pot easily. You should stick to the science of turning over the pot. Only by understanding its nature and principle, turning over pots skillfully and managing it well, can you bring vigorous vitality to orchids-strong roots and lush leaves, and flowers bloom like a scene.

Sixth, protect the buds in spring.

The new buds germinated in early spring are the best buds to grow into strong seedlings, which are very important for the growth of bluegrass and should be carefully cared for. The newly sprouted blue buds are tender and tender, and the trousers are tightly wrapped in the leaves. If there is fat water and steam dripping from the scaffolding, it will easily lead to bacterial rot and bud rot. At the same time, because the buds are tender, they like to be bitten by insects and are easy to get black spots, so we should strengthen maintenance and protect the buds. Its maintenance measures are:

1. Orchids in the open air should be protected from rain; Orchid shed and orchid room should pay attention to air convection to prevent water vapor from depositing on the roof and dripping orchid plants.

2. The pot soil should not be too wet, and the air humidity should be kept between 40% and 50% to avoid root rot and bud rot.

3. When the new buds grow to 3 cm high, fill them with culture medium and bury the bud base for half a centimeter, or fill them with bryophytes to facilitate the growth of roots.

4. dry pots and strong buds. Mr. Zheng Tongmei said in the chapter "Experiment of Bamboo Sun" that orchids are best dried in the mud once or twice, and the new buds are already thick before the grass grows; First, after mildew, it is a flower, but the surface of the basin is dry, and it is dry to the roots. Ge Lan is often nourished in pots all the year round when there are droughts in mountainous areas, which seems to be out of tune with nature, so there is a risk of thinning leaves. If the source of the dry basin is poor, the mud will rise when it is dry and wet, and the root will bite the mud when it is wet, so it can rise effectively. 5. Sterilize and disinfect, and maintain the environmental sanitation of the orchard. Spray disinfectant once a week; Spraying agricultural streptomycin or metalaxyl copper on new buds and pot surfaces every ten days to prevent rotten buds.

In a word, the preservation of spring buds is the premise to ensure the vigorous growth of orchids, which must be paid attention to. Rotting spring buds will seriously affect the growth, reproduction and flowering of the whole potted orchid. As the saying goes: spring buds are flourishing, summer buds are weak, and autumn buds don't count. If the spring buds rot and die, you won't get the new seedlings that grew vigorously that year.

Seven, bluegrass out of the room in spring.

1. Time: The suitable time for orchids to leave the house depends on the local climate. Due to the large temperature difference between north and south in China, the time of leaving the room cannot be generalized. Usually it's south first and then north. The proverb of orchid planting never comes out in spring, which is aimed at the climate characteristics in the north. Specifically, it is more appropriate to keep the temperature above 20 degrees Celsius or to leave the house between Qingming and Grain Rain, which is vulnerable to freezing injury too early and affects growth too late.

2. Adaptation: One or two days before going out, open the doors and windows of the orchid shed and the orchid room to make them ventilated, so as to gradually adapt to the outdoor climate environment. Don't rush in, wait for the orchids to leave home for about half a month, and then they can be fattened.

3. Cold protection: orchids should still pay attention to cold protection and warmth after leaving the room. Because the weather is sunny and rainy in spring, the temperature changes from time to time.

4. Disinfection: When leaving the room, conduct a comprehensive disinfection to reduce pests and diseases to the lowest point. While watching the vigorous development of bluegrass, we should also pay attention to the other hand, that is, the four prevention and control:

First, prevent fertilizer damage.

When orchids germinate and come out in spring, we should use fertilizers correctly, not too many times, and start to apply fertilizers lightly, so as not to be too thick. At the same time, we should also look at the growth of orchids themselves. Qin Ying should be applied at the stage of big seedlings and strong seedlings, and weak grass and diseased grass should be applied with little or no thin foliar fertilizer. Chemical fertilizer and organic fertilizer are used alternately on the principle of lightness and thinness. It should be applied on cloudy days or in the evening, and it should be kept away from orchids when fertilizing, so as not to hurt orchids.

Second, prevent moisture damage.

One is not to water too much, the other is to increase ventilation, and the third is to see more sunshine. When wet, excessive humidity is harmful to hairy roots and long seedlings, especially to the growth of new roots.

Three major pests and diseases.

After bluegrass hibernates, it consumes a lot of energy and its resistance is greatly reduced. When the spring breeze comes, the temperature is getting higher and higher. In addition, the blue room is not well ventilated, all kinds of bacteria are stupid, and blue is not awake, so it is the easiest to get sick. It is the high incidence of orchid diseases. Leaf fungus is susceptible, it is not difficult to control, root fungus is difficult to check, and it is too late to cure! Therefore, we should adhere to the principle of putting prevention first and combining prevention with treatment. Do a good job of killing insects and sterilizing blue house and bluegrass, and generally give blue house an all-round killing insects and sterilizing job in early March. Especially in the rainy season, it is necessary to apply fungicides and virus drugs frequently. At the same time, when using a single drug, one drug should be used three times in a row, and then another drug should be used after three times to avoid drug resistance of bacteria and viruses! It is best to mix two or more different drugs, which has a wide range of effects.

Four cold prevention measures in spring.

The climate changes rapidly in spring, with snowstorms, rainy days, cold currents and frost. The weather is changeable and the temperature is changeable. The sudden attack of cold in late spring is like a sword. If not strictly guarded, it will do great harm to bluegrass. Pay close attention to the weather forecast, and take warm and cold-proof measures in time to protect bluegrass once it strikes. Spring is not only a season of vigorous orchid growth, but also an important moment of orchid conservation, which is related to the growth and decline of orchids throughout the year. We must take it seriously and take good care of it in order to lay a good foundation for the growth of orchids in one year.

As long as we do this "seven guarantees and four precautions", I believe that everyone's orchids will sprout and bloom more. You Lan, a novice in good writing, must only read more and learn more, hold the orchid in his hand, smell the orchid, enjoy the orchid and see the leaves.
