Why does soybean only bloom and not pod? Management measures for soybean flowering and pod formation

Why does Soybean only bloom and not pod? There are four reasons why soybeans only bloom and not pod. One is that the temperature exceeds the suitable temperature for soybean growth (suitable temperature is 20 degrees); the second is that the planting land is high water and fertilizer, easy to form. "Appreciation of long-term" lodging yield reduction; third, excessive application of nitrogen fertilizer, reduction of nitrogen-fixation nodule; fourth, soil is too dry or encounters large sputum, failed to accumulate water in time; fifth, no topdressing in the early stage of pod-forming; sixth is pest and disease hazard, resulting in Soybeans only flower and not pod; seven is the seed is not purified, self-cultivation, mechanical mixing and other factors lead to soybean flowering does not pod, then Xiaobian said that soybean flowering pod management measures, I hope everyone can Helpful.

1. Pursue the flower-preserving pod

According to the specific strength of soybean, 30-40kg of urea per acre, or 20kg of urea mixed with 5kg of high-calcium fertilizer, and foliar application of boron fertilizer and chelated sugar calcium fertilizer can effectively increase Number of pods.

2, reasonable control

If the soil is full of moisture, in order to avoid the growth of soybean plants, the leaves should be sprayed with 15% paclobutrazol to control the long and madness of the soybeans, ensuring that the soybeans are more flowering and multi-pod.

3, drought protection

Soybeans are afraid of drought, so in high temperature and dry weather, it is necessary to timely irrigate to ensure sufficient irrigation, so as to prevent soybeans from drying out due to drought and pods drying up.

4. Prevention and control of pests and diseases

There are many pests and diseases in the flowering and pod-forming stage, so it is necessary to prevent the occurrence of soybean leaf blight and leaf spot disease in time and the damage of the bean pod, the heartworm, the green insect, etc. The control agent can be used with pyraclostrobin and benzepazine. A compounding agent such as azole, a vitamin salt or indoxacarb.
