Planting technology of kidney bean

To grow kidney beans, we should first select varieties suitable for the local environment, and then choose fertile and well-drained soil to start sowing. After sowing, watering and fertilization are arranged according to the change of temperature, and proper topdressing is helpful to the rapid growth of kidney beans. The prevention and control of diseases and insect pests can not be ignored, and finally arrange the harvest.

Introduction of kidney beans

1. Kidney beans, kidney beans, cottonbeans, black beans, white beans, knife beans, jade beans, etc., are cultivated species of legumes and annual twining herbs. Kidney beans originated in the tropical mountains of Central and Northern South America, spread to Europe in the 16th century, from France to Africa, from Spain to the United States, to the Philippines, and to China in the 1940s. With the development after the 1980s, kidney bean has become one of the famous legume dishes among the main high-quality vegetables in northern China and even all over the country.

2. Kidney bean has a straight root system, the root system is well developed, and the main root is developed from the radicle in the seed. There are also many nodules on the lateral roots and multistage fine roots. In the seedling stage, the main root develops rapidly, which is obvious; to the adult stage, the main root can be more than 80 cm deep. The hairy root of kidney bean is less, and the regeneration ability of root system is weak, so it is necessary to adopt root protection cultivation in production, and the seedling age should not be too long, generally cultivated in a pair of true leaf stage. Because the root nodule can fix nitrogen from the plant, the use of nitrogen fertilizer can be reduced.
