Chang Zongtang, an expert from the Yangling Association for Science and Technology and a researcher at Northwest A&F University, said that bean cultivars do not have strict requirements on the length of sunlight. They can form flower buds and bloom and set pods under longer or shorter sunlight. They can be cultivated in both spring and autumn. Most areas can introduce each other. Kidney beans are temperature-loving vegetables and are not tolerant to low temperature and frost. They should be cultivated in the frost-free period in the open field. The low temperature resistance of dwarf kidney beans is slightly stronger than that of vine kidney beans. The optimum temperature for growth in the adult stage is about 20℃, and the growth of the above-ground part is affected at 8℃. The suitable temperature for flower bud differentiation and development is 20-25°C. When the temperature is above 30°C, the growth of flower buds will be poor, the number of flowers will increase, and there will be more buds and flowers. But when the temperature is lower than 15 ℃, it is easy to appear incompletely developed flower buds and fall off. The suitable temperature during flowering and pod setting is 18-25℃. Beans are suitable for cultivation in the season when the average monthly temperature is 10-25℃. In summer and autumn, the climatic conditions are suitable for the growth and development of kidney beans, and open autumn kidney beans should be sown 90-100 days before the local frost.
