Autumn cucumber is a variety of vegetables in autumn and fall season. It has a wide market, high selling prices and considerable economic benefits. However, there is less rain in autumn, and the temperature is low in early and late periods, and the suitable growth period is short in the middle of rain. Here, I will introduce the experience of cultivation of high-yield and high-quality autumn cucumbers to farmers, and introduce them to everyone. First, pay attention to selection Strive to avoid weaknesses and choose strong, resistant varieties. After cultivation, "Jinyan No. 2" and "Jinyan No. 7" were the ideal varieties. Second, timely sowing The method of direct broadcast should be used to sow about 80 days before the local frost; if the seedlings are transplanted, seedlings can be planted 8-10 days in advance. After sowing, the soil in the Daejeon (seeding bed) should be kept moist, and the best live straw in Daejeon should be covered. It is best to put seedlings in the shade. Eyes poured (water) once every 2 days in the evening to reduce the soil temperature and make the seedlings grow quickly and neatly. Third, timely transplantation (sham) Live field when the melon seedlings have a true leaf when the seedlings, each hole to choose to leave a melon seedlings: nursery field when the melon seedlings grow a true leaf transplant, transplant should be carried out in cloudy days, sunny hot weather after 5 pm After the transplant, fill the roots with water. Autumn cucumbers, whether live or nursery transplants, line spacing can be smaller than the summer cucumbers, and each acre is planted within 5,000 plots. Fourth, strengthen management When the melon seedling grows 2 true leaves, it is sprayed once with the 200PPM “ethephon†solution to prevent legumes from growing and promoting female flowers. When the plant grows 4-5 true leaves, it should be used in time to bind the main vines and remove the side vines. During the entire growth period, topdressing 2-3 times fertilizer, each time applying ammonium sulfate 8-10 kg/mu, combined with fertilization irrigation, high temperature and high temperature, at night should be irrigation cooling, increase the temperature difference between day and night, and help improve the output and quality. In the morning, the water in the trench should be drained. V. Picking at the right time The first batch of melons at the base of the plant should be harvested early to encourage the plants to enter the reproductive growth period. When entering the prosperous growth period, tender melons should be picked as much as possible. Generally, they should be picked when the length and the maximum limit are specific to the variety. This will ensure the quality and increase the output, and the sale price will be good. When the local early frost approaches, the cucumber grows slowly and should be 1-2 days longer than the reproductive growth period. Ventilation is one of the most important components in a successful greenhouse.

If there is no proper ventilation, greenhouses and their growing plants can become prone to problems. The main purposes of ventilation are to regulate the temperature and humidity to the optimal level, and to ensure movement of air and thus prevent build-up of plant pathogens (such as Botrytis cinerea) that prefer still air conditions. Ventilation also ensures a supply of fresh air for photosynthesis and plant respiration, and may enable important pollinators to access the greenhouse crop.
