The reason for the low yield of beans

Beans are a regular customer on our table all the year round, and its market price is relatively stable, but many vegetable farmers find that the output of beans is getting less and less year after year. So what is the low yield of beans? Pro-agricultural network brings you several reasons for the low yield of beans.

1. Weather and climate reasons

Beans are grown and harvested from June to July in summer. If the continuous rainy days lead to a continuous drop in temperature, and then continuous high temperature after clearing up, it is very easy to lead to physiological and metabolic disorder of beans. When beans blossom and bear fruit, overcast, rainy and low temperature weather will slow the growth of beans, resulting in the phenomenon of falling flowers and pods. The best growth temperature of beans is 20-25 degrees. When the temperature is lower than 15 degrees, the flower buds of beans can not differentiate normally, resulting in short and slender phenomenon, resulting in low yield.

2. Improper planting management

Beans grow rapidly, from sowing to harvest only 2-3 months, planting density should be paid attention to, planting density is too high, resulting in poor ventilation and light transmittance, resulting in weak plant growth and less flowering and fruiting. In addition, when applying fertilizer, we should also pay attention to balanced collocation. If a single fertilizer is applied, it will lead to nutritional imbalance of beans and low yield. And fertilization should be more organic fertilizer, as little as possible chemical fertilizer, excessive application of chemical fertilizer, lack of trace elements in the soil, soil consolidation, poor permeability, not conducive to the growth of beans.

3. Disease and pest control is not timely.

It is inevitable to suffer from diseases and insect pests when planting beans, and some do great harm to beans, such as root nematode disease, which harms bean roots, makes them nodulate, can not grow normally, and is easy to cause plant wilting and premature senescence, no pods or poor pods. On the other hand, many insect pests break out in concentration, sucking the branches and leaves of the tender parts of beans, making them wilt or not growing, which eventually leads to a reduction in production.

4. Improper use of drugs

Above we talked about diseases and insect pests, and some vegetable farmers for pest control is very in place, bean growth liquid is normal, but there is still a low yield. This situation may be excessive or improper use of drugs, excessive or improper use of drugs will cause slow growth of bean plants, short beans, deformities, and even dim color. It is necessary to use chemicals scientifically and rationally to maintain the normal growth and fruit of beans and improve the yield and quality.

The above are the reasons for the low yield of beans brought by the pro-agricultural network, the reasons for the low yield of beans are roughly introduced here, I hope it can be helpful to you, more agricultural knowledge, please pay attention to the pro-agricultural network.
