How to manage kidney beans during the flowering stage? These precautions you need to know
Kidney beans are a common bean we eat in daily life, also known as the second-season bean and the four-season bean, and are a relatively popular pod-type vegetable. In rural areas, every household grows some. The flowering stage of kidney beans is a key point in growing them. Many growers often see a low fruit-setting rate during cultivation, which keeps yields from rising, and this is caused by improper management during the flowering stage. So if you want to achieve high yields of kidney beans, you need to pay attention to the following points during the flowering stage. Come take a look with the editor.
1. Avoid high temperatures
Kidney beans do not like high-temperature environments when grown. High temperatures often cause their vines to grow excessively, leading to poor nutrition for the flowers and pods and causing them to drop. When kidney beans are grown in greenhouses in spring, if ventilation conditions are poor, the flowering and fruit-setting rate of kidney beans is also low, and flower and pod drop will also occur later. So if you want to improve the flowering and fruit-setting rate and increase yield, you need to pay attention to temperature during the flowering stage of kidney beans and avoid the effects of high temperatures. Generally, the suitable growing temperature during the flowering stage of kidney beans is 20-24 degrees, and it should not exceed 24 degrees. Exceeding this 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 stage of kidney beans is that watering is prohibited. Watering during the flowering stage of kidney beans may cause flower and pod drop, but if the soil is too dry, it will affect the growth of kidney beans. Therefore, generally before flowering, dig a small furrow, or use the planting furrow to run a little water, to ensure that the soil is not overly dry during the flowering stage 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 improve the fruit-setting rate. Boron deficiency will cause flower and pod drop in kidney beans. Therefore, before the flowering stage of kidney beans, sufficient boron must be supplemented. Apply about 1 kg of borax per mu, or spray borax at 600 times dilution on the leaves, to improve the flowering and fruit-setting rate and avoid flower and pod drop. In addition, note that soil that is too dry or has too much standing water will affect the root system's absorption of boron. So during the flowering stage, 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 unavoidable to suffer from pests, diseases, and weeds. To save effort once and for all, many farmers often use pesticides for control, which saves time and labor and also works well. However, during the flowering stage, kidney beans are extremely sensitive to chemicals, which often leads to pesticide damage. When using chemicals, those containing pyrimethanil, mancozeb, anthracnose fumet, or diethofencarb should not be used. After using these chemicals, will the plant leaves turn yellow and die, and in severe cases cause flower and pod drop? In addition, when using chemicals, pay attention to the dosage and concentration, and also combine various chemicals scientifically and reasonably to avoid pests and diseases developing resistance. Spraying should be stopped during the flowering stage to avoid pesticide damage.
The above are precautions for the flowering stage of kidney beans. I hope it can help you. If you want to learn more about kidney bean cultivation, please stay tuned to us.
