Matters needing attention in flowering period of kidney bean

Kidney beans are beans that we often eat in our lives, also known as second-season beans and kidney beans. They are more popular beans and vegetables. Every household in rural areas will grow some. The flowering period of kidney beans is an important point for planting them. Many growers often have low fruit setting rate when planting, resulting in the yield not going up all the time. It is caused by improper management at flowering period. Therefore, in order to achieve high yield of kidney beans, we should pay attention to several points at flowering period. Let's take a look together with Xiaobian.

1, avoid high temperature

Kidney beans do not like high temperature environment when planted, high temperature often makes its branches grow excessively, resulting in malnutrition and falling of flowers and pods, while kidney beans planted in spring through greenhouse are, if ventilation conditions are poor, kidney beans flowering and fruit setting rate is also low, and flowers and pods will also appear in the later stage. Therefore, in order to improve the flowering and fruit setting rate and increase the yield, it is necessary to pay attention to the temperature at the flowering stage of kidney beans to avoid the influence of high temperature. Under normal circumstances, the suitable growth temperature for kidney beans at flowering stage is 20-24 degrees, not more than 24 degrees, which will lead to a decrease in fruit setting rate, and if it exceeds 30 degrees, flowers and pods will fall.

2. Avoid watering

A point of attention in the flowering period of kidney beans is to prohibit watering. Watering in the flowering period of kidney beans may cause flowers and pods to fall, but the soil is too dry to affect the growth of kidney beans. Therefore, a small ditch is generally opened before flowering, or a small amount of water is slipped through the planting ditch to ensure that the soil of kidney beans is not excessively dry during flowering.

3. Avoid boron deficiency

Kidney beans need an important element in flowering and pod setting: boron, boron can promote flower and pod growth, improve fruit setting rate, boron deficiency will cause kidney beans to drop flowers and pods. Therefore, sufficient boron element must be supplemented before the flowering of kidney beans. Borax can be applied by about 1 kg per mu. Borax 600 times solution can also be sprayed on the leaves to improve the flowering and fruit setting rate and avoid falling flowers and pods. In addition, it should be noted that too much drought or excessive water in the soil will affect the absorption of sprayed elements by the roots, so in order to maintain a certain humidity of the soil during flowering, it is necessary to carry out the operation of the previous point.

4. Avoid indiscriminate medication

In the process of kidney bean planting, it is inevitable to suffer from pests and weeds. Many farmers often use pesticides for prevention and control in order to save time and effort, and the effect is good. However, kidney beans are extremely sensitive to drugs at flowering stage, which often leads to phytotoxicity. When using pesticides, pesticides containing pyrimethanil, mancozeb, anthrax and ethomyl should not be used. After these pesticides are used, the leaves of plants will turn yellow and die, and serious flowers and pods will be dropped. In addition, attention should also be paid to the dosage and concentration when using pesticides, and various pesticides should be scientifically and reasonably matched to avoid resistance of pests and diseases. Spray should be stopped at flowering stage to avoid phytotoxicity.

The above are the precautions for kidney bean flowering, I hope to help you, if you want to know more about kidney bean planting knowledge, please pay attention to us.
