Conservation techniques of Orchid in Spring

The watering management of orchids is very important in spring. After the orchid comes out of the house, it should be given enough water to clean the orchid once through the clear water, remove the waste gas from the plant and the basin, and keep it moist so that the orchid can quickly restore its vitality.

When the weather is getting warmer, it is just when the new buds swell and unearth. At this time, due to the rapid volatilization of water in the basin, water should be supplied in time. Planting orchids with granular plant materials can be slightly wet. if large granular plant materials are used, they should be watered at noon so that they become wet in the basin at night to facilitate growth at night. If the water is well managed, the new seedlings can be seen growing taller almost every day.

When orchids sprout and unearthed in spring, the correct application of fertilizer is also very important. Too many times and too much fat and water will often hurt the orchid. As most orchids now use soilless granular plants, it is important to look at plant topdressing. Orchid mud, pond mud and charcoal soil are rich in fertilizers. If they are new plant materials, there is no need for more topdressing within a year, just once every half a month to once a month. Chemical fertilizer and organic fertilizer are very effective, it is better to use light and thin, choose cloudy days or evening application of fertilizer, do not let orchids stained with fertilizer solution.

In addition, it depends on the growth of the orchid itself. Big seedlings and strong seedlings should be applied nitrogen fertilizer frequently, but once every three or five days. The rejuvenated orchid should appropriately reduce the number of times, but once a month or once a week, the orchid can be absorbed. And if the grass, rootless grass, leafless bulbs are absolutely literacy, can not be fertilized, otherwise, haste makes waste, but suffer from it.

Key points for spring conservation of orchids

People usually refer to spring from the Beginning of Spring to Grain Rain. From the habit of orchids, cold orchids and ink orchids are in the late flowering stage, spring orchids are in full bloom, cymbidium is the initial flowering stage, and all kinds of orchids have entered a new growth period. The spring maintenance of orchids needs to pay attention to the following points:

Although orchids with light and temperature are semi-shade plants, the soft sunshine in spring is very beneficial and necessary for the growth and development of orchids. No matter the orchid plants are cultivated indoors or outdoors, the orchid pot should be moved to the sunny place as far as possible to receive full light. Such as orchid basin, orchid room lack of light, can be used to supplement the light source. The orchid basin can also be moved to the outdoor leeward and sunny place in sunny weather to receive sunlight, which can not only carry out photosynthesis, but also increase the temperature of the orchid plant. The time must be controlled between 10:00 and 4 p.m., especially not carelessly, leaving it outdoors for the night, hit by frost and cold winds. Thread art, crystal art and picture spot art can only accept light for a short time to prevent the degradation of leaf art. The temperature of orchid shed or orchid room in early spring should be kept above 5 ℃, and 10 ℃ ~ 15 ℃ for budding spring orchids. Occasionally encounter snow, rain, cold current, should close the doors and windows to prevent the attack of cold wind. If freezing occurs outside and the room temperature drops below 5 ℃, it is necessary to try to increase the temperature to keep the room temperature above 0 ℃. Orchid plants that are placed outdoors in winter or out in early spring must be covered with double-layer plastic film on rainy, snowy days and at night to avoid freezing damage.

Watering and fertilization has just entered the spring, the temperature is still very low, some varieties are still in the dormant period, water evaporation is slow; water demand is very little, it is generally seen that the plant surface is dry, and then irrigate the right amount of water. For Cymbidium which is about to open and Cymbidium which is pregnant with buds, it should be watered more frequently, but it should be moist with plant material. Since then, with the gradual rise of temperature, new roots and new buds sprout, the frequency of watering and the amount of water should be increased accordingly, but the basin soil should not be too wet, otherwise it is easy to cause rotten roots and buds. When the temperature rises above 20 ℃ or the weather is dry, you can spray or spray water to keep the relative air humidity between 30% and 50%. When the temperature in the early stage is below 15 ℃, except for applying phosphorus and potassium fertilizer to Cymbidium, fertilizing Cymbidium in the middle stage and promoting flowering, other orchids should not be fertilized. Comprehensive fertilization can be applied at the temperature of 15 ℃ ~ 20 ℃, but the principle of "frequent application of thin fertilizer" should be adhered to, mainly nitrogen fertilizer, nitrogen, phosphorus and potassium, usually once every half a month, and foliar spraying of 0.12 phosphoric acid: potassium dihydrogen to promote root sprouting, cultivate strong plants and enhance disease resistance.

The departure time of orchids and antifreeze orchids should be determined according to the local temperature. Due to the large temperature difference between the south and the north of our country, the time of leaving the room cannot be generalized, usually the south comes out first and the north comes out later. The proverb "Spring does not come out" is completely in line with the climatic characteristics of the north. The specific time should be controlled between Qingming Festival and Grain Rain, or the temperature is stable above 20 ℃, it is easy to suffer frost injury when leaving the room too early, and the growth will be affected if it is too late. Before leaving the room, the doors and windows of the orchid shed and orchid room must be opened on the 2nd day to make them ventilated and gradually adapt to the outdoor climate. However, due to the changeable climate in spring and large temperature fluctuations, orchids should still pay attention to cold protection and warmth after coming out of the room. Must pay attention to watch the local weather forecast, in case of late spring cold, continuous rain, flying snow, frost, to take timely anti-freezing measures, or covered with plastic film, or moved indoors to avoid serious losses.

The time of changing pots and ramet orchids depends on the size of orchid pots, the number of plants, and the strength of growth. Generally, large pot strong seedlings are replaced once every 2 years, medium seedlings and weak seedlings are replaced once every 3 years, and high tube and small pot strong seedlings are replaced once a year. When changing the basin, take the orchid plant out of the basin, shake the soil, wash the orchid root to dry, and then soak in 0.12 potassium permanganate solution for 10 minutes for sterilization. It is best to replace the new plant material at the same time and replant it in the pot. According to the requirements of spring flowering after autumn and summer and autumn flowering in spring, the corresponding plants of Cymbidium and Jianlan were divided at the same time of changing pots. Before ramet, water should be deducted to make the basin soil slightly dry and the root system soft. after rising the seedling, cut off the rotten root and old leaf, and when the root turns white, cut or break it from the wide place between the bulbs, and each clump had better have new buds or hidden buds. For the purpose of production, it can be divided into many or even individual plants, and for ornamental purposes, 5-6 plants can be divided into 1 clump, which is easy to sprout and blossom. Cut wounds should be smeared with plant ash or sulfur powder, dry slightly and then put on the basin. The water shall be watered from the edge of the basin or fed by the soaking method, and the plant material on the basin surface shall be moistened. Put the orchid basin in the shade or scattered light first, often spray water to moisturize, and move to the sunny place after half a month for routine maintenance.

The weather of disease prevention and pest control is warm in spring, which is the season for the breeding and spread of germs harmful to orchids, and it is also a good time to sterilize and prevent diseases in orchid fields. -it is necessary to do a good job in the cleanliness and hygiene of orchid cultivation sites, pay attention to ventilation and light transmission, strengthen scientific management, enhance the immune ability of orchid plants, and prevent or reduce the occurrence of diseases. Second, disinfect and sterilize with drugs. The commonly used fungicides are topzine, carbendazim, Dysen zinc, stone-sulfur mixture, Bordeaux liquid, etc., choose one or two kinds of mixture, spray the front and back of orchid leaves, bulbs and rhizosphere plants, generally spray once in 15-20 days, three times in a row, can have a good effect. Once the disease occurs, it is necessary to differentiate and treat the disease and control the disease. If you find some insect pests, you should use medicine according to them and wipe them out in time.

In spring, the watering management of orchids is very important. The weather is getting warmer, and orchids should be given plenty of water after they leave the house. Pass the orchid through the clear water, remove the waste gas and waste in the plant and the basin, keep it moist, and make the orchid recover quickly.

When the spring breeze rises and the weather gets warmer, it is just when the new buds swell and unearth. At this time, because the water in the basin soil volatilizes quickly, the water should be supplied in time. Planting orchids with granular plant materials can be a little wet. Spring is the golden time for orchids to sprout and grow, but in the south, there is a "plum rain". It rains almost every day and steams at 100% humidity. Bacteria will take the opportunity to enter and the new buds will rot away. Therefore, during this period of time, white fiberglass is often used to cover the rain, so that the orchid basin is dried and then watered according to the situation. It is different in the north, where it seldom rains in spring. If large grain plant material is used, it should be watered at noon. In this way, the basin turns wet at night to facilitate growth at night. If the water is well managed, new seedlings can be seen growing taller almost every day.

When orchids sprout and unearthed in spring, the correct application of fertilizer is also very important. Too many times and too much fat and water will often hurt the orchid. Since modern orchids mostly use soilless granular plants, it is important to look at plant topdressing. Orchid mud, pond mud and charcoal soil are rich in fertilizers. If they are new plant materials, there is no need for more topdressing within a year, just once every half a month to once a month. Chemical fertilizer and organic fertilizer are very effective, it is better to use light and thin, choose cloudy days or evening application, do not let orchids stained with fertilizer solution when fertilizing.

In addition, it depends on the growth of the orchid itself. Big seedlings, strong seedlings should be frequently applied nitrogen fertilizer, can be once every three or five days. Rejuvenated orchids should appropriately reduce the number of times, from once a month to once a week, with whether orchids can be absorbed or not. On the other hand, weak grass, rootless grass and leafless bulbs should definitely be educated and should not be fertilized, otherwise haste makes waste, and they will suffer from it.

If water and fertilizer are properly applied in spring, orchids will grow well in a year.
