The reasons for the excessive growth of beans and its control methods

Beans are one of the common vegetables on our table. In the process of growing beans, many vegetable farmers know that they are difficult to manage and often have a lot of problems. And beans grow only is a very common phenomenon, beans only grow difficult to sit pods, and even appear the phenomenon of falling flowers and pods, so what is the reason for the growing of beans? How to prevent and cure it? Let's take a look.

1. The temperature is too high

The main reason for overgrowth at seedling stage is that the temperature is too high, especially at night, which leads to too much respiratory consumption of the plant, which is very easy to make the plant grow too much.

Prevention and control methods: in the seedling stage to reasonably control the temperature, bean growth temperature between 25-35 degrees, in which the temperature of 30 degrees is the fastest, so it is necessary to control the night temperature should not exceed 25 degrees, so as not to cause excessive growth.

2. Sowing is too dense

The development of cotyledons of bean seedlings is not only the period of fastest growth, but also the most likely to cause overgrowth, which is mainly due to over-dense sowing or timely removal of mulch, which leads to overcrowding and overgrowth of seedlings.

Control methods: after emergence, time should be given to seedlings and planting, light transmission and ventilation in the field should be strengthened, temperature and humidity should be controlled well, and low temperature can control the excessive growth of seedlings. Once the seedling appears the phenomenon of overgrowth, it can also be controlled by spraying dwarf solution.

3. Improper fertilization

In addition to temperature and humidity, the main reason for the excessive growth of bean plants is improper fertilization, which is mainly caused by partial application of nitrogen fertilizer or overnutrition. In order to accelerate the survival of plants, some farmers will apply a large amount of nitrogen fertilizer when planting, and the proportion of nitrogen in the soil is too large, which will lead to plant overnutrition, which will lead to plant overgrowth.

Control methods: less available nitrogen fertilizer can be applied in planting, and farm manure or organic fertilizer rich in organic matter can be applied, which can provide nutrients for plant growth continuously and stably. On the other hand, when combined with the prevention and control of diseases and insect pests, the planting should be sprayed with hormone drugs such as Zhuangxin and dwarfin, which has an excellent effect on restraining overgrowth.

The above are the reasons for the growth of beans and prevention and control methods, hope to help you, want to know more planting knowledge, please pay attention to us.
