Sowing and management of white kidney beans;

Sowing should be timely, preferably between Qingming and Grain Rain. Generally, 7.5- 10 kg seeds are needed per mu. Every 4 rows of potato intercropping 1 row of white kidney beans; It can also be intercropped with corn, and intercropped with white kidney beans every two rows of corn 1 row. It is best to choose corn varieties with thick stems, which can be used as natural supports for large white kidney beans, but attention should be paid to proper sparse sowing to facilitate ventilation and light transmission.

Management is generally carried out 7- 10 days after sowing. When there are 8-4 true leaves, they can be thinned; 15- 20 days after sowing, the scaffold and water chestnut should be put on the shelves in time, and bamboo poles and branches can be used as supporting materials, and the height is about 1.5 meters.

There are many lateral vines in the axils near the base of white kidney bean. Although lateral vines can blossom and pod, too much will affect ventilation and light transmission, leading to falling flowers and trees and reducing yield. Too many lateral vines at the base should be trimmed. In addition, T white kidney beans have extremely strong tendrils for infinite growth, so when the main tendrils are wound on the top of the frame, the tips of the tendrils should be cut off to inhibit excessive growth.
