At present, the focus of tea farming is the prevention, rescue and pest and disease control of drought and heat damage in tea gardens. Prevention and rescue of drought and heat damage. Under attack by high temperature and drought, tea trees will show symptoms of drought and heat damage such as scorched spots, scorched leaves, and shrinkage of terminal buds and young stems after about 8~10 days, especially in young tea gardens, where it is more serious. Prevention measures: First, timely hoeing and cultivation. Timely weeding can reduce evaporation of surface soil moisture and is an effective measure to prevent drought. Production practice has proved that before hot weather begins, if drought is likely to occur, weeds should be hoed and the soil loosened immediately when the weather improves after rain. Never do this during a drought period, causing tea trees (especially young ones) to suddenly be exposed to the sun and die. Second, mulching with grass. Spread grass on both sides of the tea trees to lower ground temperature, keep the soil moist, store water, and suppress weeds. This is a good way to prevent drought and retain water. Rescue measures: For tea trees that have already suffered drought and heat damage, active rescue measures should be taken. For example, for the dead branches and dry leaves of damaged tea trees, after the drought disappears, pruning of varying degrees should be carried out according to the degree of damage. Apply quick-acting nitrogen fertilizer and potassium fertilizer in a timely manner to cultivate autumn shoots and restore the vitality of the tea trees.
