摘  要:
以长沙县"百里茶廊"湖南省茶叶研究所实验场茶园为研究对象,利用模糊数学、主成分分析及聚类分析相结合的方法,对其土壤肥力状况进行了综合评价研究。结果表明:长沙县"百里茶廊"湖南省茶叶研究所实验场茶园土壤酸化程度严重,碱解氮含量较高,速效钾含量偏低,土壤养分状况存在广泛变异,各项土壤养分指标的变异系数为24.2%~90.9%。通过对土壤肥力综合指标值(IFI)的聚类分析,茶区土壤肥力分为高、中等、较低及低4个等级,属于中等以上(高、中等)土壤肥力茶园所占的比例为61.6%,茶园土壤肥力质量总体水平属于中等水平。

摘  要:
A comprehensive evaluation of the soil fertility in the tea garden of Hunan Tea Research Institute in Changsha county was carried out by fuzzy math,principal component analysis and clustering analysis methods.The results showed that soil acidification was serious in this tea garden,the content of alkali-hydrolyzable nitrogen in the soil was slightly higher,and the content of available potassium was relatively lower.The nutrient contents in the soil varied widely and the coefficient of variation of various nutrients was 24.2%~90.9%.Through clustering analysis of integrated fertility index,the soil fertility of the tea garden was classified to 4 levels,namely high,middle,slightly low and low,and the area of tea garden with high and middle soil fertility accounted for 61.6%.So the soil fertility quality of this tea garden belonged to middle level in general.
