The latest course of cowpea cultivation techniques and methods

Cowpeas, also known as belt beans, are commonly sown and planted in spring in the south and pods are common in summer. there are many cultivated varieties and planting; they have a long history and a lot of cultivation experience. A farmer who often plants will also know a lot of relevant cultivation techniques, but there are also some things that may not be noticed by everyone, which need to be introduced to you.

I. selection of varieties

When planting, we should pay attention to select some heat-resistant and drought-tolerant varieties that have strong adaptability and can adapt to the local environment. There are also many local varieties specifically cultivated locally or native species that farmers have been spreading.

II. Site selection

Need to choose deep soil, so that the root system is better, cowpea root is not very strong, afraid of flooding, flood is easy to rot roots, so you can plant in places with lower groundwater level or high terrain. Farmers in the south often plant on the ridges of the fields, but it is better not to plant on the slopes, and the water supply is inconvenient. The loose sandy soil in the field is the best.

III. Fertilization

In the soil preparation, the base fertilizer should be combined with the soil, and then the ploughing should be mixed with fine. after planting, it needs to be watered thoroughly to promote root growth. Before flowering, the first topdressing applied compound quick-acting fertilizer to promote flower bud differentiation and ensure flowering; the second time, in the early stage of podding, more fertilization promoted multiple pods and full pods; finally, in the later stage of podding, more phosphorus and potassium fertilizer was applied in order to prolong the podding period.

IV. Field management

1. Replenish seedlings and set up a frame

Direct seeding, do not need to raise seedlings, if most of the seedlings, there are no seedlings, you can open the inspection, most of them are rotten or eaten by bugs, you can reseed. When the seedling grows to 30 centimeters long, it is necessary to build a frame to let the plant grow upward, otherwise it will be entangled with the plant. The scaffolding is usually made of bamboo strips, three bamboo strips, inserted into the soil at a uniform angle, and tied together with a rope at the top.

two。 Adjust the structure

Because of the strong sprouting ability of branches and vines, it is necessary to prune to ensure a good plant structure, remove leaf buds during flowering and podding, avoid sprouting, scramble for flower bud nutrition, not too many new shoots, plants are exuberant, leave more sides full of pods, and avoid excessive growth of lateral vines.

The basic content of cowpea cultivation is seed selection, land selection, fertilization and watering, and the key content is to set up frame and pruning, maintain good growth potential, concentrate nutrition, adjust pod branches, etc., which are all the main management contents, but also for more convenient management.
