Unsuitable temperature

The suitable temperature for kidney bean growth is 23℃~25℃ during the day and 18℃ at night. If the temperature during the day is lower than 20℃ or higher than 30℃, it will affect the sitting of kidney beans. It is necessary to regulate the temperature of the greenhouse at noon during the flowering period.

Unsuitable soil moisture

The soil in the greenhouse is too dry or too much water can cause the pods that have just been seated to appear crooked. This is because the soil is too dry or too wet to damage the root system, which leads to plant weakness and affects flowering and pod setting. Watering should be based on the soil moisture and should not be flooded to avoid root damage.

Spray sensitive drugs

Kidney beans are sensitive to mancozeb, mancozeb or dimethocarb, and the pods may bend when applied in excess. Kidney beans are very sensitive to anti-toxin alum and are prone to phytotoxicity, causing deformities in the pods. Some kidney beans are also harmed by spraying copper preparations or anthrax thiram. The light ones have bent pods, and the heavy ones have fallen leaves and pods.

Boron deficiency

Kidney beans lack boron and are not easy to sit in the pod, even if the fruit is easy to flower, the pod is long, the pod is bent, and the commodity is poor. The solution is to spray 1200 times of Sule Boron solution before the kidney bean flowers.

Excessive use of growth inhibitors

Spraying excessive inhibitors, such as chlormequat, difenoconazole, etc., on kidney beans that can't hold their pods can easily cause kidney beans to appear crooked. When spraying naphthalene acetic acid to prevent pod falling, the pod was bent due to the excessive concentration. When spraying growth inhibitors, follow the instructions for preparation and use, not excessive.

Soil solution concentration is too high

Excessive application of chemical fertilizers or saline-alkali soils can cause malformed pods, so you should use less chemical fertilizers and more humic acid fertilizers. When the pods grow to 3 to 4 centimeters, 15-30 kg of humic acid fertilizers can be applied per acre to supplement nutrients. Do not apply excessive fertilizers to increase the concentration of the soil solution and cause the pods to bend. Growing kidney beans in saline-alkali soils*** Use soilless cultivation to avoid direct contact between kidney bean roots and saline-alkali soils, which will affect root growth.
