Tea planting technology: how to improve tea quality and tea output?
How to improve the quality and output of tea? Please introduce methods to improve tea quality tea output can refer to the following methods: first, fertilization time. In spring, summer and autumn, when the new shoots of tea sprouted and grew one bud and one leaf for the first time, spray it in the early morning, evening or cloudy day on a windless sunny day, spraying 2 or 3 times a week. Spray until the leaves drip. Second, the proportion of fertilizer. The ratio of N, P, K is mainly N, P, K, and the proportion of micro-fertilizer is 4 ∶ 1 ∶ 1. The proportion of micro-fertilizer is based on the principle of what tea plant lacks and what to make up. Third, the concentration of fertilization. The concentration of fertilizer is related to the variety of fertilizer and weather conditions. According to the test, urea is 0.5%, calcium superphosphate 1%, potassium sulfate 0.5%, zinc sulfate 50~100ppm, iron molybdate 20~50ppm. If the concentration is too high, it is easy to produce fertilizer damage, otherwise it will not have an effect. Fourth, the combination of many things. It can be combined with pest control, sprinkler irrigation and plant growth regulators, saving labor and easy to realize mechanization. Chemical properties of fertilizers and pesticides. Acidic chemical fertilizers should be mixed with acidic pesticides, while alkaline chemical fertilizers should be mixed with alkaline pesticides so as not to produce chemical reactions and precipitates, so as to prevent the fertilizer and drug effects from counteracting each other. Fifth, use biological pesticides to control diseases and insect pests. The use of biological pesticides to control tea plant diseases and pests is a safe, reliable, pollution-free, pollution-free, low-cost and high-effective choice, such as Bt emulsion, cyanobacteria, Beauveria bassiana, agricultural antibiotics and plant antibiotics.
