In the production of soybeans, there is often a phenomenon of no flowers and no grain. We call it flowers and not. Next, Huinong.com will provide a reason analysis and countermeasures for the unrealistic flowering of soybeans.

First, what are the reasons for the unrealistic flowering of soybeans?

The reasons for the unrealistic flower are not only the improper selection of the variety, but also the following:

1. Sowing is too early or too late, and the meteorological factors are unfavorable after flowering. The high temperature or low temperature in soybean growth will reduce the photosynthesis of soybean, enhance the respiration, produce less nutrients and consume more, which is not conducive to soybean flowering and fruiting.

2. The proportion of soil nutrient elements is imbalanced. Boron is an important trace element to promote the growth of soybean flower pods. Boron deficiency can induce soybean flowers to be unreal.

3. Improper fertilization. Excessive nitrogen fertilizer, nutrient growth, high plants, many branches, poor field permeability caused by flowers.

Second, how to do soy flowers?

In order to avoid the occurrence of flowers, foliar spray fertilizer can be produced in production. Soybean leaves have a strong absorption capacity for nutrients, which can prolong the functional period of the leaves and have obvious effects on flowering and fruiting.

50-100g of potassium dihydrogen phosphate per acre can be mixed with 50kg of water, sprayed in the evening on a sunny day, and the sprayed part is better with the back of the blade. The flowering starts every 7-10 days and sprays 2-3 times. In the case of boron-deficient land, you can add 100g of boron and potassium dihydrogen phosphate to simultaneously apply balanced nutrients to promote fruiting and increase yield.
