Beans high-yield planting technology: how to make beans high yield?

First, planting on the ground

It is advisable to use a field that has not been planted with beans. It is necessary to disinfect it in a heavy place, because it is prone to root rot and blight in heavy shovel, causing the dead vines of the Beans, which is difficult to control.

1. Disinfection. 1 mu with quicklime 60 ~ 80 kg of polder, 7 to 10 days after drainage, whitening; 2 can be used before planting with potassium permanganate 500 times, or fangs fear (also available as carbendazim or fungus Zhen 2 ) + Bellin (Plus Jia iodine) 500 times liquid pouring soil wet more than 3 cm deep.

2, according to the height of the ground, choose to do the ridge, the ridge surface is about 40 cm wide and 30 cm high. Open a small ditch of 10 cm deep in the ridge, and use 1000 kg of decomposed manure to drench the ditch. After drying, loosen the soil, choose suitable varieties, seed soaked for 4 hours, soaked with water, seed dressing with chlorothalonil powder, 25 grams per 500 grams of seed powder, sowing in small ditch, single planting, every 20 cm seeding Two seeds, covered with soil or fired soil after sowing, and drenched.

Second, seedling management

Two days after sowing, according to the dry and wet conditions of the ridge surface, the water is drenched to ensure the water required for emergence. After 5-6 days, when the soybean meal has two leaves and one heart, use the bacteria to clear 800 times and add Jinggangmycin 300 times. 750 kg of liquid, used to control root rot, disease and other diseases. And time seedlings, guaranteed one per 20 cm. When taking the medicine, pay attention to the medicine particles and do not touch the plants. Appropriate fertilization according to the growth of soybean meal, the use of urea 3 to 5 kg per acre, plus the same amount of potassium fertilizer to water 1000 to 1500 kg, after the application of thin water. Prevention and control of soybean meal is the focus of the seedling stage. Soybean horses endanger the young heart. It is also common to have no tips, only two leaves, commonly known as "blind heart." Prevention and control of soybean meal can be 600 times of heptaphos and 600 times of benefit, or 1500 times of avermectin plus 1500 times of imidacloprid, or 500 times of good winter plus 5% of 5% of sharpen, spray once every 6 days, seedling Spray 1 or 2 times Yunda 120.

Third, the management period

The cardamom has vines to be extracted. It is necessary to carry out large-scale cultivation of soil, combined with fertilization, 30 kg of phosphate fertilizer and 10 kg of urea. Apply evenly on both sides of the ridge, cover the fertilizer and weeds with ridge soil, and pay attention to the fertilizer and soil. It is possible to apply 2,000 kilograms of manure fertilizer to the soil and cultivate the soil on the ridge side. After cultivating the soil, leaching with thiamine mixture once, using 1 kg of copper sulfate, 2 kg of carbonamine and 1000 kg of water. At the same time, the vines are put on shelves, generally with a herringbone frame. The seedlings are long and can be used with a cone frame, that is, every 40 cm, three bamboos are inserted into an equilateral triangle, and the ridge surface is tied with a rope into a cone, and the upper side frame is a horizontal bamboo. For the convenience of operation, the height of the scaffold should be controlled at 2 meters. Within. The cone can increase production by more than 10% compared to the herringbone frame. Control the water, fill the horse water once every 3 days on a sunny day, and at the same time wet the ridge surface, pay attention to drainage when it rains. The pests and diseases of the vines are mainly rust, powdery mildew, soybean meal, soybean meal, and can be used for powder rust (800-500 times) plus sulphate 500 times plus 800 times of sapphire, or 600 times of sage plus 600 times of universal powder. 800 times, pay attention to the concentration of pink rust from light to thick (800 ~ 500 times), spray once every 7 days, every other 14 days to add a cloud 120.

Fourth, harvest management

Planting for about 60 days, the plants enter reproductive growth, appear in the harvest period, fertilize once every 7 days, each time with 10 kg of compound fertilizer plus 5 kg of urea, mixed with 100 kg of manure for 3 days, add 1500 kg of water to the ridge. Noodles, thin water after application, or applied at the edge of the ridge, 20 kg of compound fertilizer plus 10 kg of potassium fertilizer plus 10 kg of urea, applied at a hole of 35 cm on the side of the ridge, each side of the ridge, 10 days later The other side is applied with the same amount of fertilizer. The water should be drenched before the application of the hole. Do not pour water on the ridge within two days after application, and do not apply fertilizer on rainy days. The harvest should maintain 1 to 2 cm of water in the furrow. Pest control can be selected to prevent spot blight and disease: 75% chlorothalonil 600 times plus 70% mancozeb 600 times; rust, powdery mildew: 50% colloidal sulfur 300 times, 1000 kg per acre , but only if the condition does not appear to be good, prevention is better than treatment. The insect pests are mainly soybean meal. Available: 1 dish is 1000 times plus imidacloprid 1500 times; 2 avermectin 1500 times plus Anthony is 600 times; 3 Bacillus thuringiensis 1000 times plus small insects 800 times. Do not mix the above three agents with fungicides. Since the control of soybean meal is very difficult, the spraying time should be sprayed once every 3 to 4 days, and the effect of opening the bean flower before 10 am is better. Add spray clouds every 7 days to 120. Harvest in the morning fog is not dry.
