2, between dense to make up for the sparse: a root and stem of multiple plants, retain robust, productive main plant, the rest of all dug out, while in the sparse place, select the good varieties of replanting. A reasonable density of about 60 plants per acre.
3, deep digging and shallow reclamation: deep reclamation in winter and shallow reclamation of root and stem cultivation in summer combined with weeding. The role is to remove weeds, improve the soil, enhance drought resistance, improve the woodland environment, reduce pests and diseases.
4, water storage and soil conservation and fertilizer: steep slopes of the forest floor, as far as possible into a trapezoidal shape, or according to the band horizontal excavation 1 ~ 1.5 meters wide bamboo ditch.
5, pruning and shaping: through pruning and shaping to improve the tea forest wind and light conditions. The old tree should be cut to the dense branches, cross branches, overlapping branches, weak branches and disease, insect branches, etc., cut out the disease and insect branches to be burned. Secondly, the pruning mouth should be coated with healing antiseptic film to prevent nutrient loss and water consumption.
6, reasonable fertilization: one is interplanted green manure, the second is the tea withered tea shells back to the mountain, the third is the application of nitrogen and phosphorus fertilizer. Fertilizer method: winter soil fertilizer, about 30 kg per plant; spring fertilizer with nitrogen, phosphorus-based composite fertilizer, 1 to 2 kg per plant.
7, pest control: adhere to the prevention-oriented, combined with tree management, in April to July, regular spraying of Bordeaux liquid or polymyxin and other fungicides. If victimized by asphodel, weevil, should choose to use 90% trichlorfon crystals 1000 times liquid spray.
8, timely picking: around October began to gradually mature, before and after the cold dew frost picking. Tea seed harvesting picking is fruit maturity directly from the tree picking fresh fruit, and then centralized treatment out of the seed. After picking the oil tea mixed with a small amount of lime, composted on the soil ping for 3~5 days, to complete the oil maturation process, and then spread the sun to remove the seeds. After drying in the sun and drying for oil extraction.
