Comprehensive Evaluation on Soil Fertility in Lincang Tobacco-growing Areas
摘要
Abstract
To understand the soil fertility status in Lingcang, Yunan province, the major nutrient contents of 41 soil samples from Lingcang tobacco-growing was determined, and soil fertility index(CCI) was established by using fuzzy mathematics. The results showed that soil nutrient contents varied much among counties in tobacco growing areas, the membership degrees of pH and chloride were less than 0.6;The CCI in Lincang could be classified into middle and high groups. Based on CCI, Lincang tobacco-growing areas could be classified into 3 groups. The group A included Shuangjiang County, Linxiang District, and Cangyuan County. The group B included Gengma County, Zhenkang County, and Fengqing County. The group C included Yongde County and Yun County. Overall, Lincang is suitable for flue-cured tobacco planting, but chloride fertilizer and organic manure are desired.关键词
