What should I do if the tea garden is hot and dry in summer?

  Since the beginning of summer this year, high temperatures in many parts of the country have turned on “stove” mode, and tea gardens are vulnerable to extreme weather, such as heat and drought, which can affect the normal growth of tea trees and the yield and quality of tea leaves. Operation with a tea plucking machine is also a big problem. Therefore, master drought prevention and control techniques and thermal damage and post-sump remediation measures to reduce losses in tea plantations.

  Irrigation of tea gardens is the most direct and effective measure to prevent drought and heat damage. Therefore, tea gardens with irrigation conditions should do everything possible to arrange water sources and use drip irrigation, sprinkler irrigation and other methods for irrigation. To resist heat and drought and prevent high temperature burns, sprinkler irrigation works best overall, and drip irrigation is the most drought-resistant water saver. Those with fixed or mobile drip irrigation facilities should use facility sprinkler irrigation whenever possible. In hot weather, irrigation should be carried out in the early morning and early evening. If possible, spray once in the morning and evening. The amount of irrigation water should be 90% relative soil moisture, which can also speed up the working efficiency of the tea garden machine.

Spreading grass between rows of tea trees or covering the ground with plant stems, sunscreen, etc., and covering bare surfaces as much as possible, can also be effective in lowering ground temperature, reducing soil moisture evaporation and improving the resistance of tea plants to high temperatures. The application of straw directly covering tea gardens has a greater effect in resisting high temperature and drought. In addition, young tea gardens should be given special attention. Since seedlings have shallow roots and are extremely resistant to drought and heat damage, shading and growing soil are also among the effective protection measures.In summer, when the tea harvester is operating in the tea garden, the tea picking efficiency can be improved as much as possible.
