Single planting or intercropping. Taking a single plant as the main crop, after the previous harvest, plow the soil, make a furrow with a width of 2 meters, plant two rows with a plant spacing of 40 cm, put two seeds in each hole, consume seeds 120 kg per hectare, sow the depth 10 ~ 15 cm, and leave seedlings 1 plant. In the case of intercropping, it can be intercropped with potato and corn, in which red beans intercropped with potato 1 row and beans intercropped with corn 1 row. Seedlings can also be transplanted.

The planting season depends on the length of frost-free period in different regions. There is no frost in winter in the south, and it is feasible to cultivate in winter and spring. Due to the high temperature in the Yangtze River valley in summer, it is advisable to choose early-maturing dwarf varieties and cultivate them in spring and autumn. High mountain areas such as Yunnan, Guizhou, Sichuan and Shaanxi, and areas with cool summer climate such as Northeast, Northwest, Inner Mongolia and Xinjiang. It can be cultivated in the open field, and can be sown on the surface layer of 65438 00 cm above 65438 00 degrees Celsius. Generally, seeds are sown in April-May, and dried beans are harvested in August-September. ① intertillage fertilization and irrigation: the root system of kidney bean has weak nitrogen fixation ability, and it is appropriate to apply topdressing 1 time at the initial flowering stage and full flowering stage in addition to adequate basal fertilizer. Weed in intertillage for 3-4 times and cultivate the soil.

Proper water control and squatting at seedling stage. Irrigation depends on the weather during flowering and pod setting. If it is dry and rainy, it needs to be irrigated 1~2 times to make the border soil not too dry. Pay attention to drainage in rainy areas to prevent water accumulation in ridges and ditches.

(2) Scaffolding and vine pruning: When plants with a height of about 30cm begin to draw vines, scaffolding should be set up in time to draw vines, excessive branches should be cut off, and it is more appropriate to leave 3-5 lateral vines for ventilation and light transmission. Isolation must be done in Taneda, because the stamens and anthers of red beans are slightly lower than the stigma, which is easy to cross-pollinate, and the natural hybridization rate is 30% ~ 40%. Therefore, seeds should be selected every year to ensure the purity of varieties. The seeds should be fully dried so that the water content of the seeds is about 65438 04%. Seeds are also vulnerable to the invasion of elephant during storage, so they should be smoked with chemicals before storage. In order to prevent insects, the seeds purchased from outside can be smoked with aluminum phosphide, and the dosage is 3.3 grams of 56% aluminum phosphide, which is used for 200 kilograms of bean seeds. After smoking in a closed container for 3 days, it can be dried for 4 days.
