The bean is neither cold nor hot and can be cultivated at a monthly average temperature of 10-25°C. Generally, the accumulated temperature of dwarf beans from sowing to flowering is 700-800°C, and the creeping species is about 860-1,150°C. High, faster development; the shorter the number of days from sowing to harvesting. Application of protective facilities for early maturing of kidney bean can extend the supply period, plug the shortage, and increase production and output value. Premature cultivation in the middle and lower reaches of the Yangtze River is mainly cultivated in the form of mulching, large and small sheds, etc., in the early spring, and also cultivated in the winter with the use of a gaze-light greenhouse and a warming greenhouse. However, the proportion is very small, and the seeding period for early cultivation depends on different protections. Ground sowing can be planted 15-30 days earlier or even earlier; the sowing time of common film-covered cultivation beans in the middle and lower reaches of the Yangtze River is from mid-March to late March, and the corresponding planting period is from early April to mid-April. The harvest period is from late May to early July. Small canopy combined with plastic mulching can be used to arrange the bean sowing dates from mid-late February to early March. The corresponding planting period is from mid-March to early April, and the collection period is from early May to late June. Plastic bean sheds combined with small arch sheds and multi-layered plastic mulching can be used to arrange the bean sowing period from early February to late February. The corresponding planting period is from late February to mid-March, and the harvest period can be from mid-April to 5 Late in the month.
