Over the years, we have used double-film covering nursery, early planting, multi-layer coverage and scientific management and other supporting cultivation techniques, so that the output of 1 mu of kidney bean reaches about 2,500 kg, and the income is as high as 6,900. Economic and social benefits are significant. Its main cultivation techniques are as follows. 1. The selection of good varieties is to choose varieties with good disease resistance, strong resistance, early maturity, high yield and good quality. Such as the preferred tender 4th, 9 white and so on. 2. Double-film covering and cultivating strong seedlings A. Site-cultivation and seedling cultivation facilities use plastic sheds to cover small arches and double membranes. Before the seedlings were raised in late February, the land was drilled to a depth of 23.3-27.0 cm, combined with deep plowing, and the plutonium was full, usually 1.2 m wide and 10 m long. B. Before planting sowing, soak the water first. After the water seeps down, use a scribe to cut the squares by 8-10 cm square. Then press a small hole on each square, about 1cm deep, sowing 3 seeds per hole. -1.5cm, arched film, film to stretch, tight around. C. Seeding after sowing. Do not let go of the wind before sowing. Cover straw at night. The straw cover should be covered with cover. Cover temperature should be kept at 25 degrees during the day and 60% of seedlings begin to bloom after 6-7 days. The method is that at 10:00 in the middle of the small arch shed, small bamboo poles should be used to support the small winds, and at 4 pm, the air outlets should be closed. The temperature of the greenhouses should be maintained at 18-20 degrees during the day. 7-8 days after emergence, in order to prevent seedlings from growing indefinitely, the membranes at the two ends of the small arch were opened at 9:00 a.m. and exhaled at both ends and closed during the day. About 20 days after sowing, when the true leaves appeared, the wind was magnified. During the day, the film on the step shed was removed and covered with film at night. Before the true leaves appeared, they were covered with straw curtains at night. 3. Management after planting and planting A. Fine soil preparation. Before applying the basal fertilization, plunge the soil and plunge 27 Cm deep. Apply 1 mus of 3500-4000 kg of cooked chicken manure, 40 kg of phosphorus nitrate, and 20 kg of urea, and then plow the soil. , Leveling the ground, do grow 10M, wide 1.2M big and wide 0.6M management line, it is advisable to use North and South. In addition, the area is warmed up in advance by slowing down the land. B. Planting In order to mention the city, the bean seedling age should not be too large. In late March, when the seedling age is 25-30 days, the first seedlings of the seedlings are planted on the first leaf and the compound leaves are selected for the proper colonization. A small open-shedded membrane covered the colonization. Before the planting, first drench the water, wait for the water to infiltrate and then bury the plastic film. When planting, planting holes were set at a spacing of 40 cm and a distance of 30 cm from each plant. Each row was 4 rows. After planting, planting holes were tightly closed with fine dry soil. C. After the planting, after the planting, the arches were covered with arches covering the shed film. The shed temperature was maintained at 20-25 degrees during the day and covered with straw curtains at night. The mulch curtains were covered every morning as soon as possible. One week later, the awnings began to put a small breeze. To control at 10-15cm, the temperature of the canopy is maintained at 18-20 degrees during the day. Normally, it starts to wind at 10:00 in the morning, and at 5:00 in the afternoon, it covers the straw at night. In mid-April, the waist wind must be placed on both ends, and straw curtains still need to be covered at night. The film was covered only at night after the rain and it was not covered with straw. After the film was removed at the end of April, the vine was introduced. Immediately after removing the film, pour water once, sit and pour the second water, and apply 1kg of urea with 10kg of urea under the membrane. The harvest will begin in mid-May and will be pulled in late August. During the fertility period, water is usually poured for 7-10 days, and each mus of urea is applied with 20-30 kg of urea or 50 kg of ammonium bicarbonate, and a total of 6-7 times of topdressing fertilizer is applied during the entire growth period. D Diseases and pests during the birth control period are mainly caused by the damage of tea plant and pods. The nymphs and larvae of the tea plant were mainly twigs, tender stems, leaves, flowers, and fruit pods, and the affected parts were brownish brown and deformed. The pods became brownish-yellow, dull, and corked. Unable to eat. If it is found in the tea plant, it can be used 72% chlorate EC 1200 times or 21% kill EC 2000 times and so on. Sprays every 10 to 14 days and sprays 2-3 times, which works well. The bean larvae damage the leaves, flowers, and pods, or drill into the pods to feed the young seeds. The pods in the pods and outside the pods are accumulated. The pods are bitter and unpalatable. Control methods: First, timely clearing the field of falling flowers, falling leaves and remove the victims of the curl leaf and pods to reduce the source of insects. The second is to promptly spray 90% crystal trichlorfon 1000 times or cypermethrin EC 3000-6000 times or 50% phoxim 1000 times or 40% cyanmethrin 6000 from buds or at the beginning of flowering. Double fluid, spray once every 7-10 days, spray a total of 2-3 times.
