1. Land selection and soil preparation: To plant cowpea in summer, choose fertile land and plough 30 cm. 2. Seed selection for accelerating germination: select varieties with high temperature resistance, high yield and high pod setting rate. 3. Sowing and shading: Scatter seeds on the soil surface and build a shading net for shading. 4. Water and fertilizer management: Cowpea needs topdressing with dilute liquid fertilizer after emergence.

How to plant cowpea in summer 1, select land and prepare soil.

Cowpea is afraid of continuous cropping, and there will be germs and pests in the continuous cropping field, which will increase the infection rate of plants. To plant cowpea in summer, we should choose fertile land where leguminous plants were not planted last year, then plough it for 30 cm, and then apply decomposed farmyard manure, calcium superphosphate and plant ash.

2. Choose seeds to accelerate germination.

When cowpea is planted in summer, varieties with high yield, high pod setting rate, high temperature resistance and long pod setting time should be selected, and then bran seeds, half-head seeds, mold seeds and miscellaneous seeds should be removed, and plump seeds should be put into gibberellin for seed dressing to improve the germination rate of cowpea.

Step 3 sow for shade

Do you need to plant cowpeas in summer according to 60 cm? Sow at a spacing of 35 cm, ensure 2-3 seedlings per hole, and then ditch around the plants, with a depth of 25-30 cm and a width of 30-40 cm, which is beneficial to drainage and waterlogging prevention. The cowpea should be shaded by a sunshade net.

4. Water and fertilizer management

Cowpea needs sufficient nutrients during its growth. When cowpea is cultivated, it should be fertilized once a month during the plant growth period. Fertilizers such as ferment bacteria and ammonium bicarbonate can be selected to promote their vigorous growth, and water them in time when the environment is dry and there is no rain.
