(A) Test Materials and Methods Experimental tea plantation for the Yunnan big leaf species, age 10 years, tea tree growth are basically the same. Fertilization management of the same district management, the same picking standards. Amino acid test 300 times, 400 times the high Meisu, 800 times liquid compound fertilizer, spraying Shi Bao 10000 times 4 treatment to spray the same amount of water as a control, repeated three times randomly arranged, each plot area of ​​0.02 acres. Spraying time for a summer tea bud early exhibition, the first for the May 20, the second on May 28, are using a knapsack sprayer spray evenly on the front and back leaves, picking a two-leaf bud standard , Each picking by hand to make a good record of production. (B) test results 1. The impact on tea production According to the summer tea spray twice after picking 5 times
