1. Choose improved varieties: If you want a very high yield, very good quality, and a relatively high commodity value when planting kidney beans, the most important thing is to choose improved varieties. Before sowing, it is best to choose seeds that are not damaged, free from pests and diseases, have about the same luster, are very plump, and have relatively large grains.

2. Fine soil preparation: Before planting kidney beans, it is best to choose a sunny location for easy drainage, far from the groundwater level, ventilation, average fertility, deep soil layer, a lot of organic matter, and the best soil. It is slightly acidic. Base fertilizer must be applied in sufficient amount. One acre uses 1510 kg to 2010 kg of farmyard manure, and now 26 kg of compound fertilizer, as seed fertilizer. It must be remembered that phosphorus and potassium fertilizers cannot be in direct contact with seeds.

3. Sow seeds at the right time: If you are planting large white kidney beans, they cannot be planted again on the same piece of land. It is best to plant corn or potatoes before the field. It is best to sow kidney beans between April 21st and May 6th. It is best to plant them in liquid tide land, which can better retain moisture, so that all the seedlings can be grown at once. When sowing, the depth is the best At 11-16 cm, then cover with about 5 cm of soil.

4. Reasonable dense planting: During the growth process, they prefer moisture, but are afraid of waterlogging. Planting in ridge cultivation can increase the ground temperature, and the drainage will be very good, making the soil more permeable. The distance between rows is 2.1-2.6 feet, and the spacing between ponds is 2010-2510 ponds. 5.1-6.1 kilograms of seeds can be used in 1 mu, and 4 seeds can be sown in each pond. If it is an upper-class field with an area of ??1,510 ponds per mu, when planting, the dimensions are 91 cm x 51 cm; if it is a middle- and lower-class field with an area of ??1,610-1,810 ponds per mu, the dimensions are 91 cm by 41 cm. The seeding rate per acre is basically 8.1-10.1 kilograms.
