1. Choosing a good variety of cowpeas after the autumn extension, it is advisable to use a high-yield, disease-resistant, high-yield plant with moderate plant growth potential, which is not easy to grow and is suitable for dense planting.
2, seeding seedling planting time should be about 80 days before the arrival of early frost. It is usually planted from late July to mid-August, and the seedling age is 15 to 20 days. It will be harvested successively in early October.
3, strengthen management of cowpea autumn post-cultivation, seedling temperature is higher, soil evaporation is large, should be properly watered to cool and protect seedlings, and pay attention to cultivating loose soil to protect the roots, seedlings promote roots, prevent high temperature and high humidity leading to length. Plant growth period, more rain, should be timely drainage and flood control.
4, heat preservation and anti-freezing cowpea flowering and pod-forming period, the temperature begins to decline, pay attention to heat preservation. In the early stage, the film around the lower part of the greenhouse should not be buckled to facilitate ventilation and ventilation. As the temperature gradually decreases, the ventilation volume gradually decreases. The film around the greenhouse was uncovered during the day and tightened at night. When the outside temperature drops to 15 °C, the film around the night greenhouse should be fully sealed. Only when the temperature is high at noon during the day, short-term ventilation is provided. If the outside temperature drops sharply below 15 °C, basically do not ventilate.
5, timely harvesting generally 50 to 55 days after sowing can be harvested tender pods.
