摘要
以广东省主要烟区11个县(市)的516个耕层土壤样本的养分分析数据,采用Fuzzy综合评判法对烟区土壤综合肥力水平进行评价。结果显示,全省植烟土壤的IFI值为0.590,综合养分肥力总体评价为强Ⅲ级。其中以Ⅱ、Ⅲ级养分肥力的土壤为主,共占64.15%;按植烟土壤类型划分,红火泥地的IFI值为0.531,牛肝土田的IFI值为0.751,沙泥田的IFI值为0.529,石灰土田的IFI值为0.738,紫色土的IFI值为0.639。
The Fuzzy comprehensive adjust method was adopted to evaluate soil fertility level in several tobacco planting regions based on nutrient analytical data of 516 topsoil samples from 11 counties （cities） in Guangdong Province. The results showed that the average IFI value of tobacco growing soils was 0.590, and generally the comprehensive nutrient fertility was the third grade. Most of them belonged to the second and third grade which accounted for 64.15%. According to the types of tobacco growing soil, the IFI value of Honghuonidi, Niugantutian, Shanitian,calcareous soil and purple soil was 0.531, 0.751, 0.529, 0.739 and 0.639 respectively.
