Why does the bean sit hard?

Colonization density should be reasonable

The seedlings of the bean seedlings were best colonized when they had just opened. The reasonable line spacing of beans is usually 60 cm in small rows, 80 cm in rows, and 1.8-2 meters in height. The higher the row spacing should be, the greater the spacing should be. The spacing is about 45 centimeters, usually two colonies. If the colonization is too big, it will cause the bean plants to be difficult to sit.

Day and night temperature difference

The beans have high heat resistance and are resistant to freezing. The suitable growth temperature is 20-25°C. In the flowering stage of flowering beans, the daytime temperature, nighttime temperature and the temperature difference between day and night should be controlled. The optimum growing temperature for the flowering period of beans should not exceed 30°C during the day and 18°C ​​during the night. Therefore, it is suggested that the farmers who grow beans should delay the shelf time with the promotion of the temperature, and the standard for the shelf life of the beans during flowering is 17°C.

The lighting conditions should be suitable

Although the bean varieties suitable for growing in greenhouses are not as demanding for light hours, they are more demanding for the light intensity, especially during flowering and sitting, if the light is insufficient, the bean corners will fall out of flower.

Soil moisture and nutrients are appropriate

Local soil moisture should be considered, and watering time and watering volume should be controlled. The basic phase of the whole growing period of beans should be poured into three kinds of water: in the first watering planting line, must be poured, otherwise the plants are uneven; when the vine grows to 0.6 meters high, the second water is poured; bean production The key is that the beans do not pour, and the water is not suitable for watering at the flowering stage of the beans. Therefore, the third water should be poured before the first flowering period, and the water spray should be used to promote the flower and fruit protection agent, which is more conducive to the flowering of the beans. . After sitting, you should pour a little water again to increase the expansion of beans. In addition, can not be partial nitrogen fertilizer, otherwise it will cause beans vine leaves long and cause delay in flowering sitting, should increase phosphate fertilizer, in order to promote the formation of root nodules, strengthen their nitrogen fixation capacity.
