| 摘 要： | 通过野外采样和室内测定,研究了湖南省洞庭湖区5个茶叶基地茶园土壤的pH值和有机质、全N、全P、全K,有效N、有效P、有效K、缓效K含量,并运用模糊综合评判法对这5个茶叶基地土壤的肥力质量进行了综合评价.结果表明,洞庭湖区5个茶叶基地土壤的pH值偏低;全N、全P含量偏低;有机质、有效N、有效P、有效K含量中等;全K、缓效K含量较高.雪峰山茶场、君山茶场的肥力质量等级为中上等;金井茶场、金华茶场和羊鹿茶场的肥力质量等级为中下等.

| Abstract: | 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, soil fertility quality was evaluated comprehensively for 5 tea bases of Dongting Lake region in Hunan province through field sampling and laboratory analysis. The results showed that contents of soil pH, total N and P contents were all low, contents of organic matter, and available N, P and K were middle, contents of total K a... |
