Advantages and disadvantages of cotton dripping in high temperature weather

The phenomenon of cotton dripping in hot weather is actually a self-protection mechanism, which can help cotton plants regulate their body temperature and reduce the damage caused by high temperature. Specifically, when cotton plants are stimulated by high temperature weather, excessive water will be discharged through stomata to evaporate body surface heat, thus lowering body temperature. This is the so-called "cotton dripping" phenomenon. The benefits of cotton dripping include: regulating body temperature: cotton dripping can help cotton plants regulate their body temperature and reduce the damage caused by high temperature. Protect the leaf surface: Dropping cotton can form a water film on the leaf surface, protect the leaf surface and reduce evaporation and water loss. Increase production: Appropriate cotton drip irrigation can improve the yield and quality of cotton, because it can adjust the growing environment of cotton and promote its growth and development. But cotton drops also have some disadvantages, including: too many drops will affect the quality; Too much dripping will lead to the decline of cotton quality, affecting cotton yield and quality. Dropping water will increase pests and diseases: cotton dripping water will form a water film on the leaf surface, which is easy to breed germs and pests and increase the harm of pests and diseases. Improper drip irrigation will harm cotton: improper drip irrigation time and dosage will cause certain harm to cotton plants.
