Cowpea is an annual twining herbaceous plant of the family Leguminosae and the genus Cowpea, and is also known as carob, ginger bean, and banded bean. China's north and south are generally cultivated throughout the country, young clip can be used as a vegetable to eat or processed pickles, canned food, dried products, etc., the seeds can be cooked porridge, rice, sauce or flour.

Cowpea is native to the tropical regions of Africa, China's north and south are generally cultivated all over the country, especially in Hebei, Henan, Gansu, Zhejiang, Hunan, Yunnan, Guangdong, Jiangxi, Sichuan, Shandong, Jiangsu and other places are the most common, the main distribution of foreign countries in India, Burma, Vietnam, the Korean Peninsula, the Philippines, Japan and other places. Cowpea likes temperature, heat-resistant, intolerant to frost, optimum temperature 20～25℃, frost damage when the temperature is lower than 5℃. Cowpea likes fertile, tolerate barren, with loose soil, well-drained and humus-rich sandy soil is suitable.

Cultivation Techniques of Cowpea

Interplanting

After cowpea has been sown, it is necessary to make real-time observation of its growth, and interplanting is necessary when the first leaves are found. Generally, two or three healthy seedlings in each hole are sufficient.

Seedling replenishment

For the poorly developed places where there is a lack of seedlings, you can replant them or move them. The replanted seedlings should be cultivated in the greenhouse for 2-3 days before transplanting, because only in this way can we ensure that all the seedlings grow at the same time and facilitate the subsequent management work.

Framing

When the cowpea reaches a certain stage of growth, it is necessary to set up herringbone frames and draw horizontal lines between the frames to establish the height of the frame according to the growth characteristics of the cowpea. Normally, the height of the frame is set at 2 meters. After the erection of the frame, the cowpea growth characteristics of the cowpea will be used as a guide for the upward trailing operation. Through continuous development, growers have improved the cowpea trellising method, transforming the herringbone frame into an X-shaped frame, and setting the height of the cross in the upward position, usually at about 1.2 meters.
