摘　　要：为优化茶园施肥技术,采用田间小区对比试验方法,开展了2种有机无机配方专用肥连续2年施用对茶园土壤理化性质及茶叶产量、品质的影响研究。结果表明:施用茶树专用肥可提升土壤pH值,显著增加土壤有机质、全氮和有效磷的含量;在化肥施用量减少20%的前提下,施专用肥的茶叶产量第1年有所减产,但第2年与对照相比已没有显著差异;经过2年的茶树有机无机专用肥施用后,茶叶中水浸出物含量、粗蛋白和氨基酸总量均有所增加。综上,茶树专用肥在茶叶产区具有良好的推广应用价值。In order to optimize the fertilization technology in tea gardens,using the method of field plot comparison test,a study was carried out on the effects of two kinds of organic and inorganic formula special fertilizers on the physicochemical properties of tea garden soil and the yield and quality of tea leaves for two consecutive years.The results showed that the application of special fertilizer for tea trees could increase soil pH value,increase the content of soil organic matter,total nitrogen and available phosphorus significantly,and under the premise of reducing the amount of chemical fertilizer application by 20%,the yield of tea with special fertilizer application decreased in the first year.However,in the second year,there was no significant difference compared with the control.After two years of application of organic and inorganic special fertilizers for tea trees,the content of water extract,crude protein and total amino acids in tea all increased.In comclusion,the special fertilizer for tea trees has good promotion and application value in tea producing areas.
