化肥减施对茶园土壤养分及茶叶产量和品质的影响研究
Study on the Effects of Fertilizer Reduction on Soil Nutrients and Tea Yield and Quality in Tea Garden
摘要
Abstract
Using field experiments,two fertilizer reduction treatments were set up,controlled release fertilizer reduction by 30%(F1)and organic fertilizer replacing 30%chemical fertilizer(F2),with conventional fertilizer treatment(CK)as the control.The effects of different fertilizer reduction treatments on soil nutrients and tea yield and quality were studied.The results showed that in the same growing year of tea trees,compared with CK,different fertilizer reduction treatments significantly increased the contents of available phosphorus,available potassium and alkali-hydrolyzed nitrogen in soil,among which F1 treatment had the most significant improvement effect,significantly increased by 114.72%,53.56%and 21.86%compared with CK in 2020.During the same growth period,both fertilizer reduction treatments significantly increased tea yield and tea polyphenol and amino acid content compared with CK,among which F1 treatment had more obvious effect than that of F2 treatment,and ensured tea polyphenol content was always at a higher level.In addition,compared with F2 treatment,F1 treatment improved the agronomic utilization rate of nitrogen fertilizer and was more conducive to enhancing the nitrogen absorption and utilization capacity of tea plants.It can be seen that soil nutrients can reach the high yield and high-quality fertility standard and tea quality and yield are optimal under the treatment of controlled release fertilizer reduction by 30%.The research results can provide a theoretical basis for scientific fertilization in Yunnan tea gardens.关键词
