What are the key points for managing kidney beans during the flowering period?

Kidney beans are a common bean we often eat in daily life, also known as the second-season bean and the four-season bean. They are a relatively popular pod-type vegetable, and every household in rural areas grows some. The flowering period of kidney beans is an important point in growing them. Many growers often see a low fruit-setting rate when growing them, which keeps yields from rising. This is caused by improper management during the flowering period. So if you want to achieve high yields of kidney beans, you need to pay attention to the following points during the flowering period. Come and take a look with the editor.

1. Avoid high temperatures

Kidney beans do not like high-temperature environments when growing. High temperatures often cause their vines to grow excessively, resulting in poor nutrition for flowers and pods and causing them to drop. When growing kidney beans in greenhouses in spring, if ventilation conditions are poor, the flowering and fruit-setting rate of kidney beans is also relatively low, and flower and pod drop will also occur later. So if you want to increase the flowering and fruit-setting rate and raise yields, you need to pay attention to temperature during the flowering period of kidney beans and avoid the effects of high temperatures. Generally, the suitable growing temperature during the flowering period of kidney beans is 20-24 degrees, and it should not exceed 24 degrees. Exceeding it will lead to a decline in the fruit-setting rate, and if it exceeds 30 degrees, flowers and pods will drop.

2. Avoid watering

One point to note during the flowering period of kidney beans is to prohibit watering. Watering during the flowering period of kidney beans may cause flower and pod drop. However, if the soil is too dry, it will affect the growth of kidney beans. Therefore, generally before flowering, dig a small ditch, or use the planting ditch to run a little water, to ensure that the soil is not excessively dry during the flowering period of kidney beans.

3. Avoid boron deficiency

During the flowering and pod-setting period of kidney beans, an important element is needed: boron. Boron can promote the growth of flowers and pods and increase the fruit-setting rate. Boron deficiency will cause flower and pod drop in kidney beans. Therefore, before the flowering period of kidney beans, be sure to supplement enough boron. Add about 1 kg of borax per mu, or spray borax at 600 times dilution on the leaves, to increase the flowering and fruit-setting rate and avoid flower and pod drop. In addition, note that soil that is too dry or waterlogged will affect the roots' absorption of boron. So during the flowering period, a certain degree of soil dryness and moisture must be maintained, which requires the operation mentioned in the previous point.

4. Avoid using pesticides indiscriminately

During the process of growing kidney beans, it is inevitable to suffer from pests, diseases, and weeds. Many farmers, in order to solve everything once and for all, often use pesticides for control, which saves time and effort and also works well. However, during the flowering period, kidney beans are extremely sensitive to pesticides, which often leads to pesticide damage. When using pesticides, those containing pyrimethanil, mancozeb, anthracnose fumate, or diethofencarb should not be used. After using these pesticides, the plant leaves turn yellow and die, and in severe cases cause flower and pod drop. In addition, when using pesticides, pay attention to the dosage and concentration, and also combine various pesticides scientifically and reasonably to avoid pests and diseases developing resistance. Spraying should be stopped during the flowering period to avoid pesticide damage.
