The reason for the low yield of broad bean

Broad bean, also known as Buddha bean in some areas, is a more common legume vegetable. It can also be used as food, feed, green manure, etc., and is welcomed by many people. When planting broad beans, what people are most concerned about is the yield. It's just that sometimes the yield of broad bean is not very ideal, so what is the reason for the low yield of broad bean? Today, the editor will give you a brief introduction. Let's take a look at it.

1. Climate

Climate factor is one of the main reasons for the low yield of broad bean. Especially in the broad bean flower and pod period, if the climate is relatively bad, encounter overcast and rainy weather. Then broad bean flowers and pods will be hit by wind and rain, and the phenomenon of falling flowers and pods will occur. And even if there are no fallen flowers and the pollen is washed and broken by Rain Water, it may crack because it absorbs too much water. It directly affects the pollination of broad bean, which leads to the decrease of yield. Therefore, we should pay attention to do a good job of management, it is best to be able to grow in the greenhouse to avoid the impact of bad weather.

2. Moisture

Although broad bean has a certain demand for water in its growth. However, we must pay attention to control the amount of water when watering, if too much watering leads to stagnant water in the soil or failure to drain in time after rain, resulting in excessive soil moisture. Then the permeability of the soil will be reduced, the respiration of broad bean roots will be blocked, and retting root rot may also occur. It is unable to absorb and transport nutrients and water normally, while broad bean plants can not grow normally under the condition of long-term lack of fertilizer and water, which leads to death, and the yield will naturally decrease.

3. Nutrition

Nutrition must be an indispensable substance in the process of broad bean growth. When planting broad beans, we should not only apply sufficient base fertilizer, but also do a good job of topdressing according to the growth of broad beans. To meet the nutritional needs of broad bean growth, if broad bean in the growth of insufficient nutrition, then the impact on its growth is very great. Especially the lack of basic elements such as nitrogen, phosphorus and potassium, as well as trace elements such as boron, will lead to a reduction in broad bean production. However, we should also pay attention not to apply too much fertilizer, especially nitrogen fertilizer, too much nitrogen fertilizer can easily lead to plant falling flowers and pods, overgrowing and so on, resulting in a decrease in yield.

4. Diseases and insect pests

Diseases and pests are also one of the main reasons for the low yield of broad bean. The common diseases and insect pests in broad bean growth are rust, red blight and aphids. These diseases and insect pests will harm the growth of broad bean plants in varying degrees, resulting in the phenomenon of falling flowers and pods. It seriously affects the yield, so in planting, we must pay attention to the prevention and control of diseases and insect pests. Strengthen management, control fertilizer and water, disinfect regularly, eliminate pests and germs in the field, ensure the normal growth of broad bean, reduce the harm of diseases and insect pests, so as to increase yield.

The above is a brief introduction to the reasons for the yield of broad bean. That's all for today's introduction. This article is for reference only. I hope it can help you all.
