The Yunnan Pu'er Ning'er county ground black town, Tong Xin Xiang, Ning Meng Xiang, Erzhen first 4 main tea producing township of formula fertilization by soil testing tea garden, soil fertility analysis that Meng first Township, relative to other three places to low soil fertility, Ning Erzhen best, followed by Tong Xin Xiang, wear black town. The "3414" after the test Ning Erzhen per mu yield increased by 111.23%, the output value reached 4465.79 yuan, nitrogen, phosphorus, potassium fertilizer were 3.14 kg / mu, 23.87 kg / mu, the corresponding optimum yield is 509.84 kg. Concentric Xiang Mu tea dry weight up to 84.03 kg / mu, according to the market survey, tea grower Mu output value reached 2212.49 yuan / mu, the best nitrogen, phosphorus, potassium fertilizer application was 24.76 kg / mu, 11.95 kg / mu, 11.05 kg / mu. The per mu yield reached 291.05 kilograms. Wear black town yield of fresh leaf growth rate reached 45.52%, the output value reached 1670.42 yuan, the per mu yield of black town grinding processing experiment of negative growth, the best nitrogen, phosphorus, potassium fertilizer application was 16.15 kg / mu, 8.83 kg / mu, 3.99 kg / mu, the optimum amount of fertilizer, output reached 214.62 kg / mu. Xiang Meng first growth rate reached 136.70%, the output value reached 5697.66 yuan, the best nitrogen, phosphorus, potassium fertilizer application was 21.46 kg / mu, 8.72 kg / mu, 4.21 kg / mu, the optimum amount of fertilizer, output reached 748.56 kg / mu. At the same time, carried out research on biological characteristics of tea tea production tests under different fertilization modes four, the test area average 500 bud weight fluctuation is fertility better Ning Erzhen and fertility relatively poor Meng Xiang Tong Xin Xiang first, and grinding black town fluctuates smoothly especially grinding black town. Fertility better Ning Erzhen plots tea bud number fluctuations than without fertilization, the remaining three township (town) volatility is high, but it is not more than Erzhen concentric Xiang Ning, the volatility of the largest, followed by grinding black town, volatility, relative to the first township two township (town) to low. Soil fertility better Ning Erzhen plots bud tea bud length is longer than the other three township (town), concentric Xiang volatility relative to other three township (town), the test area of tea bud low soil fertility Meng first Xiang sprout length maximum stability, tea bud length of each of the higher than unfertilized plots, wear black town in steady state. On the basis of the above experiment, the author hopes to effectively improve the technological level of scientific fertilization mainly tea area in Yunnan Province, hope that through good understanding of four Township tea suitable ratio of fertilization, the establishment of tea fertilizer effect function, suitable for four tea area ratio of fertilization; thus to our province tea area and reasonable fertilization, implementation of science and technology tea, take "quality, quality, famous brand" strategy, the development of pollution-free tea production, take the road of sustainable development to provide strong scientific basis and theoretical support.
