At present, the focus of tea farming is the prevention and rescue of drought and heat damage in tea garden and the prevention and control of diseases and insect pests. Prevention and rescue of drought and heat damage: under the attack of high temperature and drought, tea trees will appear symptoms of drought and heat damage such as scorched spots, scorched leaves and atrophy of terminal buds and tender stems after 8-10 days, especially in young tea gardens. Defensive measures: first, ploughing and hoeing in time. Timely weeding can reduce the evaporation of topsoil water, which is an effective measure to prevent drought.

In August, the climate is hot, which is conducive to the occurrence of diseases and insect pests. At present, the focus of tea farming is the prevention and rescue of drought and heat damage in tea garden and the prevention and control of diseases and insect pests.

Prevention and rescue of drought and heat damage: under the attack of high temperature and drought, tea trees will appear symptoms of drought and heat damage such as scorched spots, scorched leaves and atrophy of terminal buds and tender stems after 8-10 days, especially in young tea gardens.

Defensive measures:

First, ploughing and hoeing in time. Timely weeding can reduce the evaporation of topsoil water, which is an effective measure to prevent drought. Production practice has proved that before the hot weather begins, if there is the possibility of drought, we should take advantage of the rain to improve the day after tomorrow, immediately weeding and loosening the soil, must not be carried out in the dry period, resulting in tea trees (especially young) suddenly exposed to the sun and died.

The second is to lay grass. Grass is laid on both sides of the tea tree to lower the soil temperature and keep the soil moist. Storing water and restraining weeds are good ways to prevent drought and conserve water.

Rescue measures: tea trees that have been damaged by drought and heat should be actively saved. For example, the withered branches and dry leaves of the injured tea trees should be pruned in different degrees according to the damage situation after the disappearance of drought. Timely increase the application of available nitrogen and potassium fertilizer to cultivate autumn shoots in order to restore the vitality of tea trees.

Pest control: at present, the main pests are the fourth generation of tea inchworm, false-eyed small green leafhopper (the second peak), tea orange gall mite, diseases include tea cloud leaf blight and tea anthracnose.

The control agents and their dosage are as follows:

The fourth generation of tea inchworm: kungfu 20-25ml/ mu; enemy killing 20-25ml/ mu; Saidan 60ml/ mu; bt preparation 6-1000 times.

False eye small green leafhopper (second peak): 25% buprofezin 30g/ mu; 10% imidacloprid 15g/ mu.

Tea moire leaf blight: 75% chlorothalonil 75-100g/ mu; 50% carbendazim 75-100g/ mu.
