摘要
Abstract
Based on the investigation of yellow soil fertility in Liangshan tobacco planting area , a com-prehensive evaluation system was established by fuzzy mathematics and partial correlation analysis , and the a-bundance or lack and distribution situations of each nutrient index were analyzed .The results showed that the contents of organic matter , rapid available phosphorus , exchangeable calcium and magnesium were abundant ;the content of rapid available potassium was medium;but the available nitrogen content was lower .The pH value of soil showed subacid and the texture was partial viscous .The soil fertility was classified into 5 groups of high ,rel-atively high, medium, relatively low and low based on the IFI value .The soil whose fertility was medium and a-bove occupied 82.27%.Above all , the yellow soil of Liangshan tobacco planting area showed higher compre -hensive nutrient index on the whole with the change range of 0.3274~1.0000 and the average value of 0.7417.关键词
