Tea garden management points in autumn and winter

After many times of picking springs and summers, tea trees have suffered great damage to the trees. If autumn and winter seasons can promptly do a good job of tending, it will directly affect the output and quality of the coming year. The autumn and winter management of tea gardens should focus on the following tasks. 1. Deeply turn the soil. Deep plowing can be carried out in autumn and winter. The adult tea gardens are generally required to be deeply plowed once, and the depth is 15-20 cm. In young tea plantations that have not been generally deep-turned, in the year of planting, the troughs were deep-turned. Through deep turning, the soil compaction is broken and the permeability of the soil is increased. At the same time, some underground overwintering pests can also be killed. In addition, when the deep fall in autumn, even if some of the root system is damaged, due to the high temperature in autumn, it is also conducive to the timely restoration of vitality and growth of the root system. 2, reuse basal fertilizer. The amount of fertilizer in the tea plantation in the Shishi Tea Plantation in the fall is sufficient, and it is beneficial to the early spring germination of the spring tea, high yield, and high quality. When autumn tea is harvested, the application of basal fertilizer should be emphasized. Generally require the production of 100 kg of dry tea tea garden, the application of manure or compost organic fertilizer 2000-4000 kg; or with cake fertilizer 150-250 kg, phosphate fertilizer 50 kg, potassium fertilizer 20-30 kg, urea 20-30 kg, or ammonium bicarbonate 40-60 kg stratified. The bottom of the farm fertilizer, topsoil 10-15 cm at the application of nitrogen and phosphorus and potassium fertilizer, after the cover should be covered with soil to prevent loss of fertilizer. The amount of fertilizer depends on the age of the tree and the tree vigor. It means that the tree is young and the tree potential is weak. 3, trim the crown. Pruning is an important measure to promote the rejuvenation of tea plants and regulate the germination of tea buds. After the end of autumn tea, the tea trees were trimmed in the autumn and early spring when the tea trees stopped growing. However, autumn pruning often cut off winter buds and delayed the picking of spring buds the following year. According to the experience, delaying the pruning of tea leaves will help spring tea grow early and harvest early. Generally, it is carried out before mid-December. For those tea trees with good tree vigor and strong growth, only the protruding parts of the bonsai can be cut off, so that the canopy can be evenly arranged; for there are more “chicken claws”, thin branches and yields. The tea gardens that began to decline should be heavily pruned. Generally, it is required that the canopy be cut 8-10 centimeters, and the chicken claws should be completely cut off to promote the neat germination in the next season. 4, grass covered grass. After applying basal fertilizer, weeds or stalks can be placed between the tea gardens to preserve water, soil, heat, and weeds, increasing organic matter. The thickness of the grass can be seen without seeing the ground, pressing a layer of fine soil. 5, Qingyuan disinfection. After the closure of the closed tea garden in the autumn tea garden, timely disinfection of the tea garden Qingyuan, there are many benefits, you can receive a multiplier effect. One is to reduce the base number of overwintering diseases and insect pests and reduce the risk of pests and diseases in the next year. The second is to reduce the use of drugs during the production period, reduce the amount of pesticide residues in commercial tea, and improve the quality of tea; third is to ease the contradictions in agriculture. The method of disinfecting tea gardens in the Qingyuan Garden is that after the tea plantation is stopped, the dead branches of the pests are cut off, and in addition to the net tea garden weeds, the 0.3-0.5 degree stone that is treated with both diseases and insect pests is sprayed 2-3 times in the whole garden in October-January. Sulfur compound, pay attention to the positive and negative sides of the leaves and the tea tree stalks must be sprayed with liquid, each interval of 15-20 days, such as autumn and winter climate is mild, there are still tea insects damage, available cypermethrin 4000 times or 20% Sweeping 1,000 times the liquid, dichlorvos 1000 times the whole garden spray, especially in the trees to be sprayed through the spray.
