1. Scientific planting

Grow cowpea seedlings before planting, select seeds according to local climate, environmental and other conditions, prepare a seedbed for sowing, and use 50% carbendazim wettable Disinfect with 500 times of powder and sow the seeds to raise seedlings. One week before planting, the seedlings should be hardened at low temperature to improve the adaptability of the seedlings. Select the planting soil, plow it deeply and rake it 30 cm deep in advance, and apply sufficient base fertilizer. Cowpea seedlings can be planted when they are 30-35 days old. Dig holes for planting at a spacing of 25-30 cm, ensuring 2-3 plants in each hole. After planting, water the planting water in time.

2. Timely tipping

During the management period, cowpeas must be timely tipped, that is, the top growth point must be removed. All side buds below the first row of flowers on the main cowpea vine can be cut off to concentrate nutrients for cowpea growth. When the side branches growing above the inflorescence grow a few leaves, they need to be topped. When the main vine grows to 2-3 meters high, the front tip of the main vine needs to be cut off. 3. Adjust the temperature

Cowpeas are resistant to high temperatures and not frost-resistant. The suitable temperature for growth and development is 20-25°C. When the temperature is higher than 35°C or lower than 15°C, growth will be affected, so please pay attention. Adjust the temperature.

4. Water and fertilizer management

Water should be properly controlled in the early stage, and water needs should be met as it grows. After the first inflorescence sets the pods, gradually increase the fertilizer and water, and apply top dressing again when the pods are fully harvested. 5. Set up a stent

A stent should be set up when the cowpea grows 5-6 true leaves. Later, the vines will be introduced and attention should be paid to pruning and shaping.
