This is a physiological disease of cucumber and should be attributed to the category of physiological withering. The reason is that the sunlight is strong, the temperature in the shed is high, and the leaf transpiration is large. The roots can not absorb water to keep up with the amount of water loss. The leaves can wither. The middle leaves are large and thin, and the natural loss of water is the fastest. In the final analysis, this is caused by soil salinization and reduction of capillary roots. When the light is strong, you can spray water in the shade at noon to increase the microbial agent for rooting to relieve salt damage and flush with water.
