First, sowing (1) Applying the base fertilizer: After the harvest of the former crop, it will be turned 30 cm deep and dried for about 20 days. Then, 2,500 kg of farmyard manure, 25 kg of 45% compound fertilizer, 40 kg of ammonium hydrogen phosphate, and 18 cm of shallow fertilization per acre. (2) Reasonable close planting: the ridge width is about 60 cm, the groove width is 60-70 cm, the ridge height is 16-18 cm, the hole distance is 28 cm, about 8000 holes per acre, and 3 seedlings per hole. (3) Selection of good varieties: choose cowpea varieties with strong growth potential, disease resistance, heat resistance, long angle, high yield, low fiber and good cooked food. (4) Suitable sowing: It is more suitable to plant in early August. Soak seeds with 55 °C warm water and potassium permanganate 0.1% for 15 minutes before sowing. Wash and soak for 4-5 hours in water, then dry and sow. Seed 3-4 seeds per hole, live on the back of the ridge, sowing depth 3-4 cm, pour the bottom of the water after sowing, so that the back of the ridge is permeable, to ensure that the whole seedlings are broadcast. Second, management (1) Fertilizer and water management: After seedlings, timely replenish seedlings and seedlings, and keep 3 seedlings per hole. After 10 days, pour 1 small water to promote seedling growth, combine cultivating loose soil and promote root growth. When the tender angle is 3-5 cm long, water is poured once every 7-10 days to keep the soil dry and wet. When watering for the first time, 15 kg of urea and 10 kg of potassium sulfate were applied per acre to the peak of flowering and horns. The water, fertilizer and water were applied successively. The general topdressing was 2 times, the first time applying 20 kg of ammonium phosphate per mu, the second Apply 10 kg of urea per mu. (2) Temperature regulation. Cover the shade net and insect net from the beginning of September to the beginning of October. When the night temperature of the open field drops to 15 °C, the film is buckled, and the film is generally buckled around October 10. After the film is buckled, the temperature in the shed is kept at about 25 °C during the daytime. When the temperature is higher than 32 °C, the air is ventilated and cooled, and the night temperature is kept at about 20 °C. When the temperature is lower than 15 °C, the straw curtain is kept warm. (3) Plant adjustment. When the plant is vine, it is necessary to insert the "human" frame to promote the uniform distribution of the vine leaves, which is conducive to ventilation and light transmission, and reduces the falling angle of the flowers. Cowpea is strong in branching and branches grow fast. It is necessary to adjust the balance between growth and knot by pruning. Generally, the side vines of the first inflorescence of the main stem should be removed in time, and the main stem is thickened and the upper side branches are earlyly angled, and the middle side branches need to be topped. When the main stem grows to 18-20 knots, it will hit the top of the heart and promote the knot. Third, harvest Generally, harvesting starts 60-65 days after sowing, and it is harvested once every 2-3 days at the beginning of the knot. It is harvested once a day during the peak period and the harvest period is about 50 days. Disclaimer: Some articles on this website are transferred from the Internet.
