Report on Application of Controlled Release Fertilizer in Tea Garden

In order to alleviate the negative influence on soilhardening,environmental pollution, decreasing quality of tea, made a test on nitrogen stage regulation technology during 2012 — 2014. The data of yield,increasing rate,N absorption of new shoot, amino acid content, tea polyphenol content, amino acid- tea polyphenol ratio were treated with analysis of variance. The results showed that applicated controlled release fertilizer could increase N absorption of new shoot, decreased amino acid- tea polyphenol ratio, improve quality and yield and reduce production cost. Therefore, applicating controlled release fertilizer could reach the expected goal of increase yield and improve quality.
