| 摘 要： | 以长沙百里苗木走廊苗圃为例,在实地调查与采样分析的基础上,对土壤肥力各单项指标进行了诊断分析,然后采用模糊数学综合评判法(Fuzzy法)对各苗圃基地进行了土壤综合肥力评价.结果表明长沙百里苗木走廊苗圃基地土壤pH值偏低,土壤质地粘重,有机质和土壤全氮及速效氮含量中等偏低,土壤磷和钾素养分含量较丰富,各苗圃基地综合肥力大都属于中等偏上水平,其中丘陵岗地苗圃基地综合肥力明显低于谷地和丘平地.

| Abstract: | Integrated evaluation on soil fertility in Changsha corridor of nursery seedling was conducted by Fuzzy evaluation method. The result indicated that pH value was lower, the soil texture was heavy clay, the content of soil organic matter, total N and available N was below the middle grade, the content of P and K was plentiful in the soil. The integrated fertility in nursery base was higher than the average, and that in hilly land was lower than the average. |
