In autumn and winter, the weeds and litters between the tea trees are the places where pests and germs are hidden. Clearing the garden in time will help reduce the number of overwintering pests in the tea garden. The overwintering pests of tea plants mainly include small green leafhoppers, tea leafhoppers, leaf blight, round spot disease, and fleas and fleas. Can be used 0.7% half Bordeaux mixture, 40% dimethoate 1000 times, 50% marathon 1000 times liquid and 0.3-0.5 Baume degrees of lime sulfur for prevention and treatment. During spraying, the tea plexus was sprayed up and down, inside and outside, and the front and back of the blade were sprayed. Weeds on the ground and shoots in the pod were also sprayed to improve the control effect. The closure of the garden will end before the end of November. Before the onset of the cold wave, it is necessary to do a good job of ploughing the soil, fertilizing soil, and paving the grass in time. In the tea garden line, apply some cow manure, coke ash, phosphorus and potassium fertilizers and other warm fertilizers to help increase soil temperature. After fertilization, soil shall be cultivated in time and a new 8-10 cm thick soil layer shall be planted at the base of the tea tree to prevent the root system from being exposed to frost damage. For tea gardens with serious water and soil loss, we must do a good job in earth-cultivation. After the soil is cultivated, local materials can be used to cover the tea tree rows and roots with fireweed, straw, and manure, so as to help increase soil temperature and maintain soil moisture. Before the onset of the cold wave, it can be covered with straw, weeds, or films, and the cover can be removed in time to open the spring, in order to prevent the tea tree from freezing, promote the early spring sprouting of the tea tree, develop strong shoots, and achieve high quality and high yield of spring tea.
