Beans are also known as cowpeas, and their habits and cultivation techniques are similar to those of green beans. The growth characteristics of bean pods Although rhizobia can fix nitrogen, they are harvested with tender pods and tender bean grains, so nitrogen supply is indispensable, especially in the early stage. Nitrogen: Phosphorus: Potassium = 1:0.6:1.3. Trace element molybdenum promotes vigorous growth of root nodules. Beans are also sensitive to boron, zinc, and other trace elements. Therefore, based on rational application of N, P, and K fertilizers, spraying Boron, molybdenum and zinc fertilizers have a certain effect on improving the rate of scabs, promoting grain filling and increasing yield. Let's talk about the high-yielding cultivation techniques of legumes. Root rhizobia are aerobic, which is one of the reasons why kidney bean can tolerate short-term soil drought and poor moisture resistance.
First, soil preparation and selection of fields that have not been planted with beans is appropriate, and the crop must be disinfected because it is very prone to root rot and blight, and it is difficult to prevent and cure.
1, disinfection. 1 mu of lime 60 to 80 kg of Putian, 7 to 10 days after the drainage, whitening; 2 can be used before the planting 500 times potassium permanganate, or bean bacterium fear (also can be used Badaming or Bacteria Zhenqing 2 ) + Bellin (Gaga iodine) 500 times more than 3 cm deep.
2, according to the level of land to choose to do ridge, ridge width of about 40 cm, height 30 cm. Open a small ditch with a depth of 10 cm in the ridge, and 1000 kg of decomposed manure water in the mu. After rinsing, choose the suitable variety. Seeds are soaked in water after 4 hours of drying. Seed dressing with chlorothalonil is used. 25 grams of seed powder is used per 500 grams of seeds. Seeds are sown in the small trenches and planted in a row at intervals of 20 centimeters. Two seeds, after sowing, covered with earth-fertilizers or fire-soiled soils.
Second, seedling management sowing two days according to the wet and dry conditions of ridge surface light water, to ensure the required water for emergence, after 5 to 6 days when the bean pods with two leaves as one heart, with bacteria poison clear 800 times plus Jinggangmycin 300 times Once again, 750 kilograms of medicinal liquid for mu were used to prevent root rot and epidemics. Timely seedlings, guarantee a strain every 20 centimeters. Be careful not to touch the plant when taking the medicine. Appropriate fertilization according to the growth conditions of soybean meal, mu urea 3 ~ 5 kg, plus equal amount of potassium fertilizer 1000 ~ 1500 kg, after the application of thin water. Prevention and control of soybean pods is the focus of the seedling period. Soybean pods harm the young shoots, which is also commonly seen in the absence of shoots. They see only two leaves, commonly known as “blind heartâ€. Anti-fibrin can be used to control 600 times the amount of water amifluosporin plus 600 times the benefit of sweeping, or avermectin 1500 times imidacloprid 1500 times, or a good 500 times in winter and 5% fipronil 1500 times, spray once every 6 days, seedlings Spray 1 to 2 times Yunda 120.
Third, pumping ranch management pods have vines out, to carry out large earth, combined with fertilization, acres of phosphate fertilizer 30 kg plus urea 10 kg, evenly applied to both sides of the ridge, with ridge ditch to cover the fertilizer and weeds, pay attention to fertilizer and mud Do not touch the bean stems. There are conditions to apply 2000 kg of manure in Mushi, in the ridge edge soil. After the earth is soiled with thiamine mixture, 1 kg of copper sulphate, 2 kg of carbonic amine and 1000 kg of water are used. At the same time, the vines are put on the shelves. Generally, they are used with a human frame. The seedlings are long and can be used as a taper, that is, every 40 centimeters, with three bamboos inserted into an equilateral triangle, tied from the ridge to the cone with a rope, the upper side of the horizontal bamboo, for ease of operation should control the height of the scaffold 2 meters Within. Tapered racks can produce more than 10% more than a rack. Control the water content. In sunny days, horses and horses should be insulted once every 3 days, and the ridges should be wetted. Pay attention to drainage on rainy days. The insect pests in the vine rafting stage are mainly rust, powdery mildew, bean pod horses, and soybean meal. The use of triadimefon (800-500 times) can be used to add 500 times more of the amines of phosphorothioate and 800 times of Anluobao, 600 times of that of Xiansheng, and 600 times of that of Wanpan Powder. 800 times, pay attention to triadimefon concentration from light to strong (800 to 500 times), spray once every 7 days, every day plus 120 spray clouds.
IV. Harvesting Management Sowing for about 60 days, the plants enter the reproductive growth, and the harvest period appears. Fertilize once every 7 days. Each time, mu compound fertilizer 10 kg plus urea 5 kg, manure 100 kg mix for 3 days, add water 1500 kg applied to the ridge surface, after the application of thin water, or in the ridge edge points, acres of compound fertilizer 20 kg plus 10 kg of potash and urea 10 kg, in the ridge edge 35 cm to open a small hole, apply a ridge on each side After 10 days, apply it on the other side with the same amount of fertilizer. Before the application of acupuncture points, sufficient water should be given. Do not apply water on the ridge surface within two days after application. Do not apply fertilizer on rainy days. Harvesting should maintain 1 to 2 cm of water in the furrows. Pest control The following agents can be selected to control spot blight and epidemic diseases: 75% chlorothalonil 600 times plus 70% mancozeb manganese 600 times; rust, powdery mildew: 50% colloidal sulphur 300 times, 1000 kg per acre , but the premise is that no illness is better, and prevention is better than cure. Insect pests are mainly soybean meal, available: 1 dish hi 1000 times imidacloprid 1500 times; 2 avermectin 1500 times plus Anluo treasure 600 times; 3 Bacillus thuringiensis 1000 times plus pest enemy 800 times. The above three kinds of agents should not be mixed with bactericides. Because the control of soybean meal is very difficult, the spraying time should be sprayed once every 3 to 4 days. Before 10 o'clock in the morning, the spraying effect of tofu blossoms is better. Every day, plus 120 big clouds. It is advisable to harvest water in the morning.
