How do beans bear more pods?

The planting density should be reasonable: the best planting age is when the heart leaves of bean seedlings are just unfolded. The reasonable row spacing of beans is generally 60 cm in small rows, 80 cm in large rows and 1.8 cm in height. The higher the frame is, the larger the row spacing should be, and the plant spacing is about 45 cm, which is generally planted in two plants. If the planting density is too high, it will cause the bean plant to grow too hard to set pods.

The temperature difference between day and night should be checked: beans have strong heat resistance and are not resistant to freezing, and the suitable growth temperature is 20 ℃ ~ 25 ℃. During the flowering and pod setting period, the daytime temperature and night temperature and the temperature difference between day and night should be well grasped. The suitable growth temperature of bean during flowering period should not exceed 30 ℃ in daytime and 18 ℃ at night. Therefore, to remind all bean growers to put off the shed time, it is necessary to postpone the shed time with the increase of air temperature. the standard of soya bean flowering and pod setting period is that the greenhouse temperature reaches 17 ℃.

The light conditions should be suitable: although the bean varieties suitable for planting in the greenhouse do not have strict requirements for the number of light hours, they have higher requirements for light intensity, especially during the period of flowering and pod setting, if the light is not enough, it will cause beans to drop flowers and pods.

Soil moisture and nutrients should be appropriate: the watering time and amount of water should be flexibly controlled according to the local soil moisture. The most basic thing in the whole growing period of beans should be watered: after planting, the first watering must be thoroughly, otherwise the plants are uneven; when the vine grows to 0.6 meters high, the second water is watered for the second time; the most important thing for bean production is to water beans without pods, so the third water should be watered before the early flowering stage, and combined with watering to promote flowers and fruit protectors, which is more conducive to bean flowering and pod setting. After setting pods, you should pour a little water again to promote the expansion and elongation of beans. In addition, nitrogen fertilizer should not be applied, otherwise it will cause excessive growth of bean vine leaves and delay flowering and pod setting. Phosphate fertilizer should be applied to promote the formation of root nodules and enhance its nitrogen fixation ability.
