If the contaminated tea, especially the export product, its value, reputation will be seriously undermined. In order to improve the quality and yield of tea, in addition to taking tea green fertilizer, covering moisturizing enough manure each postharvest facilities, as well as other measures to improve the tea process foliar outside companies, but also clever use of fertilizer, the amount of fertilizer small, quick, high-yielding good way, and can yield more than 20% to 30%. Its fertilization techniques are: a, fertilization time. In the spring, summer, autumn rounds germination grow tea bud early show shoots, select windless sunny morning, evening or cloudy spraying once a week and even spray 2 or 3 times. Foliar spray to drip so far. Second, the ratio of fertilizer. Nitrogen, phosphorus and potassium-based, fertilizer, giving a ratio of 1 pixel in horizontal, fertilizer conducted in accordance with the ratio of tea what we lack principles. Third, fertilizer concentrations. Concentration of fertilizer varieties and fertilizer, weather conditions factors. According to tests, 0.5% urea, superphosphate 1%, 0.5% potassium sulfate, zinc sulfate 50 ~ 100ppm, iron molybdate 20 ~ 50ppm. If the concentration is too large easy to produce fertilizer damage, or not achieve results. Fourth, more binding. Can be combined with pest control, irrigation and foliar spraying plant growth regulators, not only saving labor, work is also easy to implement mechanization. Fertilizers and pesticides and chemical properties. Acidic fertilizer to go with acidic pesticides, fertilizers should be equipped with basic alkaline pesticides, it will not produce a chemical reaction, precipitation, to prevent offsetting fertilizer and pharmacodynamics. Fifth, the use of biological pesticides to control pests. The use of biological pesticides to control pests tea is safe and reliable clean pollution-free, high efficiency and low cost of the anti-choice, such as Bt emulsion, caterpillar fungus, Beauveria bassiana, agricultural antibiotics and antibiotics and other plants. Nitrogen should generally be in fruit growth stage, post-use fertilizer, appropriate with phosphorus and potassium. Spraying appropriate concentration can effectively promote shoot growth foliar Price, improve fruit yield beneficial flower buds. Early use of urea concentration of 0.2% to 0.3%, the latter using a concentration of 0.3% to 0.5%; composting human waste pre-concentration of 0.5%, the latter using a concentration of 10%. Spraying should have less fertilizer early, late and more principles. In the best ammonium concentration of 0.5% to 1%; potassium dihydrogen phosphate at a concentration of 0.2% to 0.5%; superphosphate leaching solution at a concentration of 1% to 3%.
