1. Cultivation season. According to the regional and climate of Guangshui City, seasonal cowpeas can be sown in stages from March to July. 2. Sow. Seed sowing in spring is generally in early April. Determine soil moisture before planting, sowing or planting two lines per plant. Sowing depth 3--4 cm. The amount of 2 kg per acre is used for seeding and covering the film. 3. Nursery. Early spring cowpea seedling transplanting can reduce the loss of dead seedlings caused by low temperature and high humidity, and can improve the harvest time by increasing the harvest time. Seedlings are generally 10-15 days ahead of live broadcast. Seedlings are planted in mid-to late March. Use plastic nutrient bowls with a diameter of 8 cm, soak 2 seeds per pot, soak the nutrient pots before sowing, and cover the soil 2 cm after sowing to cover the mulch. , Plus a small arch shed, do not lift the film before the emergence, do a good job of cold insulation, seedling age of about 20 days for transplanting. 4. Soil fertigation. Early spring planting should be chosen to shelter from the sun, combined with site preparation and base fertilizer. Use air and light to increase production. For a width of 1.3 meters, it is advisable to apply rotten pig cow dung or chicken dung, and apply calcium superphosphate and calcium sulfate. 5. Colonization and density. When sowing, sowing line spacing 40--50 cm, hole distance 20--25 cm, sowing 3 - 4 tablets per hole, seedlings in the late seedling stage, leaving 2 plants per hole. Sowing in summer and autumn can increase the density due to a short period of vegetative growth, and the density of a plot with poor fertility can be appropriately increased.
