Skillfully applying foliar Fertilizer to improve the quality of Tea
If famous tea is contaminated, especially the export products, its output value and reputation will be seriously compromised. In order to improve the quality and output of tea, in addition to planting green manure in tea gardens, covering and moisturizing, applying sufficient farm manure after each harvest, and improving tea-making technology, foliar fertilizer should also be used skillfully, which is a good way to use less fertilizer, quick results and high profits. generally, the yield can be increased by more than 20% and 30%. The technology is: 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. Fertilizer ratio. With nitrogen, phosphorus and potassium as the main, supplemented by micro-fertilizer, the proportion is 4:1:1, and the proportion of micro-fertilizer is based on the principle of what tea plant lacks. Fertilization concentration. The concentration of fertilizer is related to the variety of fertilizer and weather conditions. According to the test, 0.5% urea and 1% superphosphate. 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. 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. Biological pesticides were used 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.

Manufacturing technology of black tea
The manufacturing process of black tea is to kill green, knead, pile and dry. Among them, woodpile is a unique process in the manufacture of black tea, and it is also a key process to form the quality of black tea. The main results are as follows: (1) because the leaves picked by black tea are thick and old and the water content is low, they need to be stir-fried at high temperature and stir evenly, showing dark green. (2) after kneading and killing green leaves out of the pot, immediately knead and twist while it is hot, it is easy to shape a good shape. The method of kneading is the same as that of ordinary black and green tea. (3) the rolled leaves are piled on the bamboo mat, 15 thick.
