What is the reason for the rest of beans?

A lot of crops in the planting process will occur rest phenomenon, and once the rest phenomenon occurs, then the yield of the crop will be greatly reduced. Beans are one of our common vegetables. What should we do once the season stops? Let's take a look at it together with Xiaobian.

I. Bean rest symptoms

Bean resting mainly manifested in weak plant growth potential, yellow leaves, reduced flower quantity, dropped flowers and pods, resulting in a serious decline in yield. Generally, this phenomenon mostly occurs in summer when the high temperature weather lasts for a long time, that is, in the dog days, so it is called rest.

II. Causes

1. High temperature

Beans have certain requirements for temperature, germination suitable temperature between 25-30 degrees, seedling stage is higher, usually between 30-35 degrees, and flowering pod suitable growth temperature between 25-28 degrees, once the temperature is too high, then beans are prone to normal pollination.

2. Drought and rainy

In summer, many areas are hot and rainy, but once the rainy season lasts for a long time, the field is prone to ponding, and the roots of beans will rot and lack oxygen. In summer, if there is no rain for a long time and the temperature continues to be high, it will also lead to slow growth of beans and decrease in flower quantity. Moreover, after summer rainfall, the temperature rises rapidly, which is easy to cause pests and diseases.

3. Improper management of fertilizer and water

In the process of planting, it is easy to overwater, especially improper watering at seedling stage, excessive use of base fertilizer, partial application of nitrogen fertilizer and other problems, which easily lead to excessive growth of beans, resulting in less flowers, fewer pods and low yield in summer.

III. Prevention and control measures

First of all, before planting, we should select improved varieties and sow them in time. Before planting, we should select varieties that meet market demand according to local actual conditions. It is suggested to select bean varieties with good heat resistance, strong resistance and stable yield to reduce the possibility of resting. Then it is necessary to control the field environment well to avoid excessive growth. First of all, it is necessary to plant closely and refine seedlings at seedling stage to avoid excessive growth at seedling stage. In addition, we should pay attention to the pruning and topping of beans, avoid the high position of bean pods, affect the yield, there are many diseases and insect pests in summer, and also do a good job of prevention and control measures.

The above is the beans rest is what reason introduction, hope to help you, want to know more related knowledge, please pay attention to us.
