What is the reason for the latest resting of beans?

Many crops will have a rest in the planting process, but once the rest occurs, then the yield of the crop will be greatly reduced. Beans are one of our common vegetables. What should we do once we have a rest? Come and have a look with the editor.

1. Resting symptoms of beans

The main manifestation of bean resting is the weakening of plant growth potential, the decrease of yellow leaves, flowers, falling flowers and pods, resulting in a serious decline in yield. Generally speaking, this phenomenon mostly occurs when the summer high temperature lasts for a long time, that is, in three-volt days, so it is called resting.

II. Causes of occurrence

1. High temperature

Beans have certain requirements for temperature, the suitable temperature in the germination stage is between 25 and 30 degrees, the seedling stage is a little higher, usually between 30 and 35 degrees, and the suitable growth temperature in the flowering and podding stage is between 25 and 28 degrees, once the temperature is too high, then beans are extremely prone to abnormal pollination.

2. Dry and rainy

It is high temperature and rainy in many areas in summer, but once the rainy season lasts for a long time, the field is easy to accumulate water, the root system of beans will rot, lack of oxygen and so on. In summer, if there is no rain for a long time and high temperature continues, it will also lead to slow growth of beans and reduction of flowers, and after summer rainfall, the temperature rises rapidly, which is very easy to cause diseases and insect pests.

3. Improper management of fertilizer and water.

In the process of planting, it is easy to occur excessive watering, especially improper watering at seedling stage, excessive use of base fertilizer, partial application of nitrogen fertilizer and so on, and it is very easy to grow beans, resulting in less flowers, less pods and low yield in summer.

III. Prevention and control measures

First of all, the improved varieties should be selected to sow at the right time before sowing, and the varieties that meet the market demand should be selected according to the local actual conditions before planting. It is suggested that the varieties of beans with good heat tolerance, strong resistance and stable yield should be selected to reduce the possibility of rest. The second is to control the field environment, in order to avoid excessive growth, first of all, reasonable close planting, seedling stage should also be refined to avoid excessive growth of seedling stage. In addition, attention should be paid to the pruning and topping of beans, so as to avoid the pod position of beans to be too high, affect the yield, and there are many diseases and insect pests in summer.

The above is the introduction of the reason for the rest of beans. I hope it can help you. If you want to know more about it, please follow us.
