通过野外采样和室内测定,研究了长沙县"百里茶廊"6个茶叶基地的土壤pH,有机质,全N、P、K,有效N、P、K以及缓效钾等指标的土壤肥力状况,并以此为评价指标,运用模糊综合评判法,对这6个茶叶基地的土壤肥力质量进行了综合评价.结果表明,长沙县"百里茶廊"6个茶叶基地的土壤肥力质量均属于中等水平,土壤pH值偏低,全N、全P含量偏低,有机质含量和有效N、P、K含量中等,全K和缓效K含量较高,并据此提出了该地区高产优质茶园建设的若干建议.

Taking the nine indices,i.e.,soil pH,organic matter,total N,P and K,available N,P and K,slowly available K,as assessment parameters,by use of fuzzy comprehensive assessment the paper comprehensively evaluated soil fertility quality for 6 tea bases of Baili Tea Zone in Changsha county through field sampling and laboratory analysis. The results showed that soil fertility quality of 6 tea bases of Balli Tea Zone in Changsha County were of medium level in all. The soil pH,and total N and P contents were all low. The contents of organic matter,and available N,P and K were middle. The contents of to...
