The pods of late-maturing soybeans are not solid. What will the temperature cause the pods of soybeans to be not solid?

It is grown in many areas and has good nutritional and economic value. However, when we plant soybeans, we often find that the soybean pods are not full, which will seriously affect our yield and cause us losses. This is especially true for late-maturing soybeans. Why is this?

What happens if the late-maturing soybean pods are not solid?

When planting soybeans, late-maturing soybean varieties are prone to having pods but no fruits. If the temperature is low during the filling period of late-maturing soybeans, the low temperature will cause the soybean fruits to expand slowly, and the soybean pods will easily become empty.

When planting soybeans, local climate conditions must be considered. Temperatures below 15°C or above 33°C will affect the growth of soybeans. If the temperature is low during the pod-setting period of soybeans, early-maturing or mid-maturing varieties should be selected for planting.

Will temperature cause soybean pods to become unripe?

The flowering and pod stage is a critical period for the number of soybean pods. The most suitable temperature for the flowering and pod stage is 22-28℃. If the temperature is higher than 32℃ during the flowering and pod stage, it will easily cause soybean flowers to fall, affecting the differentiation of flower buds and the fertilization of pollen. Even if the soybeans are podded, empty pods are likely to appear, which will seriously reduce the yield and quality of soybeans.

If the temperature is too high, you can set up a shade net to provide appropriate shade, and spray water to cool down after the sun sets.

What should I do if soybeans have heartworms?

Soybean pod borer, commonly known as soybean pod borer or small red worm, mainly harms soybeans. The larvae usually bore into the pods from the joints and eat the beans inside the pods. One larva can eat about two beans, causing the pods to be unfilled. When the soybeans are ripe, the larvae break away from the pods and burrow into the soil to make cocoons for the winter.

When planting soybeans, it is necessary to rotate them reasonably with other non-legume crops and try to avoid continuous cropping; choose soybean varieties that are resistant to woodworms, such as smooth-pod soybean varieties and varieties with a high degree of lignification; deep plow the soil in autumn to turn the overwintering insect eggs to the soil surface, and use the low temperature in winter to freeze the eggs to death.

Soybeans are native to China and are cultivated in various parts of China. They are also widely cultivated around the world. Soybeans are one of China's important food crops, with a 5,000-year history of cultivation. They were called "shu" in ancient times and are mainly produced in Northeast China. Soybeans are a crop whose seeds are rich in plant protein. Soybeans are most commonly used to make various soy products, extract soybean oil, brew soy sauce and extract protein.
