Cultivation Techniques of Autumn Bean and Winter Bean in Sunlight Greenhouse
One, site preparation In early July, the former crop will be cleared and the land will be leveled. The quality of organic fertilizer shall be 10000-15000 kg per mu, 50 kg of diammonium phosphate, 20 kg of potassium sulfate, 20-30 cm of deep-dip, deep-watered, sealed membrane 7— In 10 days, high temperature was used to kill germs and eggs, and the organic fertilizer was thoroughly decomposed. Ten days later, the air was released and the top and bottom sides of the film were rolled up in a sky-like shape. Rilling but not covered, ridge spacing 120 cm, Ridgeback Chichi 70 cm, furrow width 50 cm, ridge height 15-20 cm, 3-5 days before sowing ridging ridge water. Allow the soil moisture to be sown or planted. Second, sowing The cultivation of autumn beans and winter pods of greenhouse beans is a season of high temperature and strong light, and the method of non-film-covered direct seeding is beneficial to the emergence and root development. After the seedlings are unearthed, the cultivator shall be cultivated in a timely manner, depending on the soil moisture, no drought or watering, so as to prevent the seedlings from growing steeply under high temperature and high humidity conditions. Third, management 1. Temperature management: Before the arrival of frost in early September, the shed film was buckled. In early October, the convective wind formed by the top wind and waist phoenix was dominant. After mid-October, the top wind was replaced. When the minimum temperature in the outside world drops below 12°C, it is closed at night and ventilated during the day, and the air volume is gradually reduced as the outside temperature decreases. The temperature is maintained at 20-25°C during the day, 19-23°C during the night, and 25°C during the day. To cool off the air, if it is below 10°C, cover with cotton or straw curtains to prevent cold currents from attacking and avoid death of frozen plants in all fields. 2, water and fertilizer management: Bean drought tolerance, seedling stage to try to control watering, leaves do not appear wilting droop does not water, enter the pod period, need to increase the water supply, the soil remains moist and loose, but the soil surface can not There is stagnant water, otherwise, the oxygen capacity in the soil will decline, the roots will be stunted and the plants will become yellow. When the air humidity is high, the pollen cannot develop normally and the flowering is serious. In the early stage of scab, every 5-7 days, pouring water, top dressing with water, topdressing 15 kg of urea per mu, 5 kg of potassium fertilizer, or 1,000 kg of liquid fertilizer of biogas residue, or 10 kg of potassium sulfate, to accelerate the rapid hypertrophy of soybean meal. From late October to mid-November, kidney beans enter the fruit-bearing period, gradually reducing the amount of watering and the frequency of watering as the outside temperature decreases, and pouring water once every 10 days or so. With the further decline in the outside temperature, the physiological and biochemical functions of kidney bean gradually depleted, the absorption capacity of the roots was greatly reduced, and the watering fertilizer was stopped. The harvesting period could only be extended by covering and incubating. 3, bean pest pest control The main diseases of greenhouse bean include bean rust and bean grey mold. The main insect pests are locust, red spider and greenhouse whitefly. (1) bean rust Control methods: selection of disease-resistant varieties to strengthen the management of field management chemicals At the beginning of the disease, spray 15% triadimefon WP 1000-1500 times, or 50% or 50% sulfur suspension 300 times, or 25% deconcentration oil 3000 times, prevent 1 time in 10 days, continuously or Alternately apply 2-3 times. (2) Botrytis cinerea: strengthen field management Chemical control: In the early stage of the disease, spray 50% fast-inking WP 1500-2000 times, or 50% acetaminophen wettable powder 1000-1500 times. (3) Greenhouse whitefly: Due to its strong fertility, fast breeding speed, large population, and harm to colony, it secretes a large amount of honey liquid, which seriously pollutes the leaves and fruits, and often causes the occurrence of coal pollution. [Control methods]: Agricultural control, promote the first greenhouse planting whitefly celery, garlic yellow and other low-temperature-resistant crops; greenhouse installed insect nets; avoid cucumber tomatoes, beans mixed plant, avoid greenhouse cultivation of cucumbers, tomatoes, Eggplant, beans, and other whiteflies are serious vegetables. Chemical control: Kike killing emulsifiable concentrate 1000 times; 1.8% abamectin emulsifiable concentrate 3500 times; swift smoke killing agent fumigation, once every other day, 3 times in succession.
