Application of low-yielding tea

Feature, set the NPK ratio of 15:6:4, and the formulation containing 10% rare earth. By 31 points, 3-year comparison test,[link widoczny dla zalogowanych], fertilizer than urea, and NPK (Western European production N: P: K = 15:15:15) pretty. Promotion in 1994 has been accumulated more than 6,000 hm. Yunnan tea is currently diazo light of phosphorus, potassium is still fairly prominent, and likely to cause soil compaction, tea premature aging, poor quality tea. Rare earth fertilizer Sang Cha, because earth containing 10% tea to meet the needs of different minerals. At the same time for containing SO-. . To create a slightly acidic soil environment, the growth of tea is very beneficial. To verify the tea in the low-yielding mulberry garden of rare earth compound the effects of the transformation,[link widoczny dla zalogowanych], the author conducted in 1999 and comparison test, are summarized as follows: 1 Materials and methods 1.1 for the test fertilizer plant production, bag high-quality middle-inferior> 0.30.20.1> 0.20.150.1> 0.80.60.40.90.60.30.60.450.32.41.81.2 stubble after harvest to remain about 60% of the phosphorus in the soil, the second crop after harvest there are still about 30% of the phosphate to remain in the soil. Large amount of weak acid phosphate fertilizer residue,[link widoczny dla zalogowanych], to promote application of high concentrations of phosphorus fertilizer. In addition to the overall balance fertilization, but can choose to fertilizer response function method and target yield with method, among them are not mutually exclusive, in determining the program with the application of fertilizer and complementary. I. 1I �� 194 Agricultural Science Supplement 2002 installed 50kg / bag, N: P: K: = 15:6:4, and contains 10% rare earth. 1.2 Test sites and test site features tea, Yunlong Town, Temple of Azure Clouds in Chuxiong tea, tea growing medium, fertilizer for many years, spaced 1.8m, age 26 years. 1-3 design options including no fertilizer application (hereinafter referred to as Area A), applied only once a year, fat area (hereinafter referred to as Area B) and applied twice a year fat area (hereinafter referred to as C,) a total of 3 treatments, each treatments with 3 replications, plot area 0.033hm. Repeat both between and around the tea isolation. Fertilization method for broadcast facilities (who pulled a small planter), specific criteria for the B, fertilization 750kg/hm, on March 6 facilities; C District 6 March for the first time fertilization 750kg/hm!, 8 �� 6 �� second fertilization 750kg/hm. 1.4 survey items (1) 1999 full year production of fresh leaves, dry tea production. (2) annual average number of plant bud. (3) Autumn standard (60om Peng surface height) pruning, the cut quality of the fresh material (including branches, leaves, fruit, etc.). 2 Results and analysis 2.1 fresh yield and dry tea production output of fresh leaves throughout the year in various districts in Table 1 and Table 1 shows the yield of dry tea B, C District fresh yield was much higher than A, were 157% and 236% higher; dry tea production B, C areas were 156% higher than A, and 231%. That rare earth fertilizer Sang tea tea production has greatly improved results. 2,2 average bud number per plant of Table 2 Number of various plant average bud can be seen from Table 2, Cha Sang rare earth fertilizer can greatly increase the number of plant bud. Tea bud a few more, that increase yield per unit area, increasing tenderness, helping improve the quality of tea. 2,3 After the fall pruning pruning weight of Table 3 the weight of the repeat region analyzed l1 pruning tea season ends in mid-January, on the tea plantations were raised 60cnl Peng high standard trim, cut material weight in Table 3. Table 3 shows the weight of material cut B, C area than A, has greatly improved,[link widoczny dla zalogowanych], indicating that tea mulberry plants of rare earth fertilizer has increased the role of products of photosynthesis, the plant nutrition of tea is a comprehensive and effective. 3 Summary (1) low-yielding mulberry tea tea rare earth fertilizer application on tea production and improve yield and quality obviously. Whether fertilizer once or twice, have greatly increased production; C Area B, several indicators although larger than growth, but growth rate has declined, indicating that the initial fertilization of tea mulberry obvious effect of rare earth compound. (2) rare earth fertilizer Sang Tea tea after application, increased bud number, increasing tenderness, improve quality and enhance the cold resistance, where the application of rare earth fertilizer Sang had tea tea, tea, soft and strong support, although the case of the winter frost snow, still flourish, as the tea quality,[link widoczny dla zalogowanych], efficient and productive foundation.
