How to make more beans

It is difficult to manage the beans in the greenhouse, and it is difficult for Yiteng to sit down and fall. How can we get more knots and improve the production of beans?

First of all, the bean density should be reasonable. The seedlings of beans are the best time for planting when the leaves have just unfolded. Reasonable line spacing is generally 60 centimeters in small rows, 80 centimeters in height, and 1.8 to 2 meters in height. The higher the row spacing should be, the greater the spacing should be. The spacing is about 45 centimeters, and it is generally planted in pairs. If the colonization density is too large, it will cause bean plants to grow indefinitely.

Second, the temperature difference between day and night should be checked. The beans have strong heat resistance but are not tolerant to freezing. The suitable growth temperature is 20°C to 25°C. In the flowering stage of the bean pods, the day and night temperatures and the temperature difference between day and night should be mastered. The flowering period of beans should not exceed 30°C during the day and 18°C ​​at night. Therefore, to be properly ventilated with the changes in temperature, the standard for the flowering of the beans during flowering is 17°C.

Third, increase the light intensity. Although the varieties of beans grown in greenhouses do not require strict light hours, they require relatively high light intensity. Especially during flowering, if the light is insufficient, the bean corners will cause flower failure.

Fourth, skillfully apply fertilizer and water. The whole growing period of beans should be poured with at least three waters: for the first time after planting, the first watering must be done; otherwise, the plants are uneven; when the vine grows to 0.6 meters high, the second water is poured; Flowering is not suitable for watering, so the third water should be poured before the first flowering period, and combined with water spray to promote flower and fruit protection agent, which is more conducive to flowering and sitting beans. After sitting, you should pour a little water again to promote the expansion of beans.

Beans can not be partial nitrogen fertilizer, otherwise it will cause the beans vine leaves long and cause delay in flowering sitting, should increase phosphate fertilizer, in order to promote the formation of root nodules, enhance their nitrogen fixation capacity.
