Generally speaking, tea trees will suffer from hot and dry symptoms such as focal spot, burnt leaves, and atrophy of tips and shoots after 8-10 days in high-temperature and dry weather. Especially young tea gardens are more serious and should be prevented and remedied as soon as possible.
Preventive measures (1) Scratch in time to reduce surface water evaporation. Before the onset of hot weather, if there is a possibility of drought, the grass should be plucked immediately after the weather turns rainy. Be careful not to perform in the dry season so as not to cause the tea tree (especially the young tea tree) to die. (2) The grass is planted on both sides of the tea tree to reduce the temperature of the soil, keep the soil moist, and suppress the growth of weeds.
Remedial measures For tea trees that have been damaged by heat and drought, after the drought has disappeared, pruning should be carried out in varying degrees according to the victim's conditions. The combination of root fertilization and foliar fertilization should be used to promptly increase available nitrogen and potassium fertilizers to cultivate autumn shoots. To reduce the impact on tea production in the coming year.
