Kidney beans, also known as beans, long beans, native to tropical regions of southeastern Asia, including southern China, East Asia, and India, have a long history of cultivation in China, and are cultivated in various parts of the South and North, and are cultivated in the South. Variety types are cowpea stem length, can be divided into dwarf species, semi-manifold species and vine species. According to the length of the fruit, it can be divided into long bean and short bean. According to the color of the skin of Nenjang, it can be divided into the species of green bark, white bark and red bark. Vegetable kidney beans are mainly vine varieties, and a few are vineless varieties.
The cultivation of the nursery facilities for nutrition and seedlings can be appropriately sowed earlier and the seedlings for nutrition can be planted in greenhouses in the middle and early March. The autumn sowing period is suitable for Liqiu. Seedlings for nutrition cultivation, with 6 pieces of fully cooked manure, 4 pieces of mountain mud, 4 pieces of manure, 6 pieces of garden soil, well-mixed and sieved, and 6 centimeters in diameter and 8 centimeters in height. The food is neatly and neatly placed in a leveling nursery. Soak the nutrient pods before sowing. After the water is soaked, sow the treated seeds in the pods (2 seeds per pod) and then cover the sieved nutrient soil for about 3 cm. Seedling transplants can inhibit vegetative growth and promote reproductive growth. In early spring, seedlings can also be sowed early, harvested earlier, and extend the harvest time.
The seedlings of live seedlings are weak in root regeneration, and they are often broadcast live. When sown in open field, the seeds are sown when the temperature rises above 20°C to increase the germination rate. Before sowing, the selected seeds are soaked in warm water of about 30°C for 1 to 2 hours, then germinated at a temperature of 25 to 28°C, and sown when the buds are whitened. You can also broadcast seeds directly. During live broadcasting, they are usually planted at a spacing of 33 centimeters (66 centimeters) in diameter, planted at depths of 4 to 6 centimeters, about 3,000 holes per acre, and 3 to 4 seeds per hole. Planting density should be determined according to cultivars, cultivation measures, etc. The main vine pods are the main species, and the stems and leaves are small. The varieties suitable for dense planting, such as fine leaf blue, can increase to 4000-5000 points per acre. The green soybean meal varieties should be planted densely in comparison with the white soybean meal varieties. It is necessary to carry out the proper dense planting of whole vines. After the emergence of seedlings, leaving 2 to 3 per hole.
The temperature of the seedlings should be maintained at 30~35°C before unearthing. After unearthing, the appropriate temperature should be controlled at 25~30°C. After planting in early spring, take a plastic shed and cover the plastic film. After emergence, the film is peeled off at noon, and the film should be completely removed before the exit of the nursery, so that the seedlings grow fully and robustly. Before the emergence of water should not be too much to prevent seed rot. After emergence, soil should be kept moist. The seedbed should prevent the soil from drying out and should not be overly watered. It should also prevent the seedbed from accumulating water.
