The reason for the latest low yield of broad bean

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

1. Climate

Climatic factors are one of the main reasons for the low yield of faba beans. Especially in broad bean flower pod period, if the weather is more severe, encounter rainy weather, then. Then the broad bean flower pod will be due to wind and rain, and there will be flower drop pod phenomenon. And even if there are no flowers, pollen washed by rain burst, but also because of excessive water absorption and burst. It directly affects the pollination of faba beans, resulting in a decline in yield. Therefore, we should pay attention to the management work, it is best to be able to plant in greenhouses to avoid being affected by bad weather.

2. Water

The plant needs water to grow. However, we must pay attention to controlling the amount of watering when watering, if too much watering leads to water in the soil or fails to drain water in time after the rain, causing excessive soil moisture. Then it will reduce the permeability of the soil, the respiration of the roots of broad beans is blocked, and there may also be rot of the roots. Unable to absorb nutrients and water normally, and broad bean plants in the long-term lack of fertilizer and water under the state can not grow normally, seriously lead to death, yield will naturally decline.

3. Nutrition

Nutrition is definitely a substance that cannot be lacking in the growth process of fava beans. 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 growth of broad bean nutrition needs, if the broad bean in the growth of insufficient nutrition, then the impact on its growth is very large. In particular, the lack of basic elements such as nitrogen, phosphorus and potassium, as well as trace elements such as boron, will lead to broad bean yield. However, attention should also be paid to not applying too much fertilizer, especially nitrogen fertilizer. Too much nitrogen fertilizer is easy to cause plants to drop flowers and pods, grow long, etc., resulting in reduced yield.

4. Diseases and pests

Disease and insect pests are also a major cause of low yields in broad beans. 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 to varying degrees, resulting in the phenomenon of flower and pod dropping. Serious impact on yield, so we must pay attention to the prevention and control of diseases and insect pests in planting. Strengthen management, control fertilizer and water, disinfect regularly, eliminate pests and germs in the field, ensure the normal growth of broad beans, reduce the harm of pests and diseases, and thus improve yield.

The above is a brief introduction to the reasons for broad bean production. Today's introduction is here, this article is for reference only, I hope to help everyone oh!
