Organic tea seedling management
First, drought and seedling protection. After planting the seedlings, we should always keep the soil of the tea-pots moist. If it is sunny and not rainy, we must water the irrigation and pour water for 4 to 7 days. Second, the seedlings make up seedlings. Using the same age of tea seedlings in the establishment of the park within 1 to 2 years will be filled with missing seedlings. Third, weeding and weeding. The combination of shallow tillage and weeding for 2 to 3 times a year can reduce evaporation of topsoil and increase soil permeability, which is conducive to the growth of tea plants. Fourth, pay attention to fertilizer. The tea plants planted in the fall begin to be fertilized in the middle and late March of the second year, and they are usually dredged with manure water once or twice a month. The principle is to apply light and heavy fertilizers, gradually increase the concentration, and make a reasonable mix of nitrogen, phosphorus and potassium. Fifth, pest control. Can only use bio-pharmaceuticals (bt powder, Beauveria bassiana, etc.) plant extracts, or artificial removal; after the winter tube with lime sulfur agent once seal garden medicine. Six, reasonable cutting. After the first year of tea planting, the tea seedlings will have less tea and will be topped for the second year. After the tea plants are planted, they are pruned at a height of 0.9 to 1 foot from the ground, and are pruned at a height of 1.2 to 1.3 feet from the ground. After that, the cuts are increased by about 1 inch per year. Seven, disable the material. (1) Fertilizers include: all chemically synthesized hormones such as urea, ammonium bicarbonate, ammonium sulfate, and ammonium nitrate; compound fertilizers, compound fertilizers, and waste fertilizers. (2) Pesticides: All chemically produced pesticides, including herbicides, plant regulators, insecticides (powders), fungicides (powder).
