After the lunar lunar new year, the tea gardens were harvested and stopped before the beginning of winter. At this time, the growth of the tea tree was slowed down, and the growth of the underground roots was still very strong. This is an important period for the management of tea gardens. First, basal fertilizer. Spring tea germination and growth, 80% of the nutrients from the first year of autumn and winter tea tree roots absorb nutrients from the soil. In autumn and winter, when the amount of fertilizer applied to tea gardens is sufficient and nutritious, the spring tea of ​​the following year germinates early, yields high, and the quality is excellent. The main organic fertilizers that can be used as basal fertilizer include cabbage cakes, livestock and poultry manure, compost and various soil miscellaneous fertilizers, etc. Base fertilizers should also be suitably equipped with quick-impact commercial NPK fertilizers. The amount of basal fertilizer is generally 50% to 60% of the total amount of fertilizer used in the whole year. Take tea plantations with 800 kg of fresh leaves per mu as an example. Mushi cakes should be used for 100 kg (or water manure 50 lbs) plus urea for 40 kg and phosphate fertilizer. Kg, potassium sulfate 10 kg. Basal fertilizer is generally combined with the autumn tea plantation by deep slashing method, that is, a groove of 20 to 30 cm in depth is cut vertically along the edge of the canopy, and the sulcus soil is loosened, applied to fertilizer, and finally covered with soil. Pay attention to the use of ash, fertile soil and chlorine-containing fertilizers in tea gardens. Second, mild trim. After the closure of the park and the closure of the park, the prominent branches and branches of the pests on the tea-pods were lightly trimmed once to ensure that the buds were neatly trimmed to promote the formation of lateral buds and increase the density of tea heads. Pay attention to pruning should be light should not be heavy, as much as possible to retain the green leaf layer, cut in the trimming of the previous year on the basis of 2 to 3 cm, the time to cut back buds can be formed but not the most appropriate time for germination. Pay attention to the high-altitude tea plantation cut first and the low-mountain tea plantation cut. Third, the Qingyuan disinfection. Stopping and sealing the garden immediately after the disinfection of tea garden, one can reduce the base number of disease and insect overwintering, reducing the risk of pests and diseases the following year; Second, reduce the production period of medication, reduce pesticide residues in commercial tea, improve tea quality. The method is based on cutting off the dead branches of the pests and removing the weeds from the net tea. The whole park sprays 0.3-0.5 Baume degrees of lime sulfur agent twice. Pay attention to the front and back of the leaves and the tea tree branches. Spray at intervals of 15 to 20 days.
