长沙县“百里茶廊”6个茶叶基地的土壤肥力质量评价

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。

Assessment for Soil Fertility Quality of 6 Tea Bases of Baili Tea Zone in Changsha County

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 total K and slowly available K were high. According to the results,some suggestions about the construction of no-harm tea garden in this area were put forward.
