How to manage cowpea after planting

Cowpea is what we call long beans in our daily life, which is rich in nutritional value and has a very large market demand in our country. The planting mode of cowpea is mainly seedling transplanting, which can effectively increase the yield and expand the planting benefit. Therefore, the management of cowpea after planting is very important, so how to manage it? The following editor brings you the management skills after cowpea planting, let's have a look!

1. Rational watering

After planting, it is necessary to pour stable seedling water to improve the survival rate of seedlings. Then the seedlings were watered again after entering the slow seedling stage in autumn and winter, and again after the slow seedling was over. Then do a good job of ploughing and hoeing to promote the squatting of seedlings and improve the ability of soil moisture conservation. Must pay attention to control the amount of water, do not water too much, otherwise the accumulation of water will easily lead to dead seedlings. In the future, it should be watered reasonably according to the growth stage of cowpea seedlings, such as proper drip irrigation at bud stage and no watering at early flowering stage. Reasonable watering method can effectively improve the survival rate of cowpea seedlings.

2. Scientific fertilization

Before planting, we should first apply sufficient base fertilizer, and then apply phosphate cake fertilizer once in the cowpea seedling stage, and the amount of cake fertilizer per mu should be controlled at about 60kg. When topdressing, we should apply less fertilizer before anthesis and more fertilizer after anthesis. After the planting survived, the mature farm manure was applied once, and the amount of farm manure per mu was controlled at about 1000 kg. Then increase the amount of fertilizer application and reduce the frequency of fertilization after flowering. When topdressing, we should reasonably adjust the proportion of fertilizer nutrition according to the growth of cowpea and soil fertility and other factors to ensure the normal growth of seedlings.

3. Build the shed in time

Cowpea is a kind of trailing vegetable, so we should pay attention to building a shed after planting. After planting, the seedlings should be set up in time when they begin to shake off the vine, so as to avoid intertwining with each other, affect the growth, lead to falling flowers and pods, and reduce the yield. The stent of cowpea should be inserted about 12 cm from the base of the seedling, and the depth of the scaffold should be kept at about 18 cm. Then tie a bamboo pole in about the position of bracket 4x5, do a good job of drawing vines and let cowpeas grow along the bracket. Building a shed in time can effectively increase the yield of cowpea, so we must pay more attention to it.

4. Pest control

Pest control should not only be paid attention to after cowpea planting, but also should not be relaxed during the whole growth period of cowpea planting. There are different diseases and insect pests in different growth stages of cowpea, even in the whole growth period of cowpea. Therefore, after planting, we must strengthen management, spray disinfection regularly, and do a good job in ploughing and weeding. The common diseases and insect pests are anthracnose, Botrytis cinerea and bean pod borer and so on. After planting, we should often observe the growth of seedlings, and when we find the disease, we should make corresponding treatment in time to control it.

The above is a brief introduction to how to manage cowpea after planting. After planting, we should also do a good job of replenishing seedlings, pulling out some weak seedlings, diseased seedlings and dead seedlings in time, and then replanting healthy seedlings with the same growth, so as to improve the seedling rate and yield. That's all for today's introduction. This article is for reference only. I hope it can help you all.
