Beans are a common vegetable in our daily life. They are grown in every household in rural areas, but the phenomenon of leaf curling leaves occurs during planting, which seriously affects the photosynthesis of leaves and directly affects the yield. So what is the bean leaf roll? Let’s take a look. 1, phytotoxicity Bean leaves are curled up, probably because the pesticides are sprayed on other crops, causing pesticides to scatter on the beans and causing phytotoxicity, which is a common phenomenon in rural areas. When causing damage to the leaves caused by phytotoxicity, it is necessary to wash the leaves with water in time, reduce the concentration to be connected, recover as soon as possible, or increase the light to reduce the harm caused by pesticides. 2, lack of water and fertilizer When the beans are cultivated, the lack of water and fertilizer will cause the leaves of the beans to curl up. At high temperatures, the transpiration of the beans leaves is large, and the water evaporation is large. If there is water shortage, it will shrink and curl. At this time, it is necessary to properly water the beans and replenish the water supply. In the air drying, it is necessary to spray water properly, increase the air humidity, and at the same time, apply fertilizer in an appropriate amount, and the yield increase effect is obvious. 3, lack of light Beans are plants that prefer light. If there is not enough sunlight during planting, its leaves will gradually curl up until it is dead. Therefore, it is necessary to ensure sufficient light when planting. If the lower leaves are unable to obtain sufficient light due to excessive growth, they can be trimmed at the right time to increase permeability, and a large amount of watering should be supplied under strong light to avoid leaf wilting. 4. Pest and disease hazards If the bean is damaged by pests and diseases, its roots cannot grow normally in the soil, and the leaves will curl, yellow and dry. At this time, it is necessary to cut off the branches and leaves of pests and diseases in time to keep the growing environment ventilated smoothly, and it is also possible to properly apply fertilizers and spray corresponding chemicals.
