The Effect Of Utilizing Fertilizer In North Tea Garden On Tea Plant Growth And Tea Quality

Tea plant like growth in acidity soil, the best pH between 4.0-6.5, but SHAN Dong soil pH is on the high side, and that reducing some element validity, witch caused the tea plant undernourishment. So it is a cry for problem that improve SHAN Dong tea garden nutrition condition.It is a effective method by supply nutrition for tea plant by fertilizing, witch not only supply ample nutrition for tea plant growth but also improve soil condition a certain extent, so it can solve the nutrition problem in north tea garden radically.In this experimentation we fertilized in north new tea garden and determined some index and researched the effect of fertilizer for tea output and quality. The following researchs were conducted by the author:1. Fertilization in north tea garden with bioorganic fertilizer, Microbial fertilizer, Organic-inorganic complex fertilizers, Mineral nutrition fertilizer, Release-controlled fertilizer, Foliar-fertilizer.2. Determined the tea plant growth index. The results indicate that in this experimentation all fertilizer can accelerate the tea plant growth and increased the tea output. The index of one hundred buds weight, bud density, output had obvious increased compared to the comparison. In all treat, utilized Bioorganic fertilizer and Foliar-fertilizer in one treat have the best effect on tea plant.3. Determined the tea plant photosynthesis index. The result indicate that compared to the normal tea plants, all fertilizer in this experimentation can enhance tea plant photosynthesis speed, and some fertilizer can reduce cell gap carbon dioxide concentration, but all the fertilizer have little effect on tea plant stomatal conductance and transpiration rate. 4. Determined the tea plant biochemistry component content. The result indicate that the fertilizer have obvious effect on tea polyphenols and amino acid content. Utilized Bioorganic fertilizer and Foliar-fertilizer in one treat have the most obvious effect on tea polyphenols and amino acid content. Bioorganic fertilizer have best effect in all treat without Foliar-fertilizer on tea polyphenols and amino acid content. All fertilizer treat have little effect on tea theine and tea extract of water content.
