The cowpea planting has the characteristics of short production cycle, less investment, labor saving and labor saving. After the cowpea is harvested, it can be planted with summer corn, summer peanuts and other vegetables. The production of cowpea is about 1,500 kilograms per mu. In recent years, the mu gain has been more than 3,000 yuan, and the planting benefit has been outstanding. Here are some of the highlights of cultivating spring cowpea.
First, fertilization site preparation
Choose fertile medium loam cultivation, base fertilizer Mushi maturity farmyard fertilizer 5000 kilograms, nitrogen phosphorus potassium ternary compound fertilizer 50 kilograms. Combine fertilization with ploughing and hoeing. The rake is 20 centimeters high and 50 centimeters wide. A horizontal line is used every 3 meters. Then select the sunny and weatherless film, use a mulch with a width of 1m, and compact both sides of the mulch to prevent wind damage.
Second, timely sowing
When the temperature is stable at 10°C for 5 consecutive days, it can be planted. In the south-central part of the province, the sowing time for mulching can be advanced to early April. Production can be selected for disease resistance, good yield, and other varieties of beans King, with the amount of 6-7.5 kg per mu. Use a hole puncher to drill and sow the seedlings in the film. The depth of sowing is about 3 cm, the distance between the points is 30 cm, and 3-4 seeds are planted in each hole. Each row is sown in two rows with a spacing of 20 cm.
Third, field management
When the seedlings break the ground, compact the edges of the mulching film around the seedlings with soil to prevent the wind from tearing the mulch film. Observe carefully after the storm and weather. If there is accumulated water on the membrane, remove the accumulated water. The damaged membrane should be pressured or re-laminated in time. Bean seedlings grow to 3-4 true leaves when the first water, with the water Mu topdressing 15 kg of nitrogen and potassium fertilizers, after entering the peak period in May, after topdressing 1, Mushi urea 20 kg. Kidney beans have strong resistance to diseases, generally do not need to use drugs for prevention and control. In the collection period, imidacloprid can be used to control insect pests such as aphids.
Fourth, timely harvest
It usually takes about a week from the flowering of soybean meal to the harvesting of soybean meal. The mulch spring pods generally enter the harvesting period in early May. At this time, it is the peak season for market demand, with large consumption and high prices, which can be appropriately harvested earlier to obtain higher economic benefits.
