摘要: 为了解襄阳市植烟土壤肥力状况,2019年对全市3个烟叶产区961个土壤样品5项养分指标进行检测分析,运用主成分分析法确定各土壤养分指标的权重,并运用模糊数学隶属度函数对土壤肥力状况进行综合评价。结果表明,全市植烟土壤pH处于适宜范围的占比为41.73%;速效钾、有效磷含量整体较丰富,处于高水平范围占比分别达60.87%、66.29%;有机质含量整体偏低,处于高水平范围占比仅为18.73%;碱解氮含量处于高水平范围的占比为34.96%;全市植烟土壤综合肥力指标值平均为0.58,变异系数为31.28%,处于中等及以上水平占比达80.85%。襄阳市大部分植烟土壤适宜优质烤烟种植。

Abstract: In order to clarify the status of tobacco planting soil fertility in Xiangyang city, five nutrient indices of 961 soil samples from three tobacco-growing areas were tested and analyzed in 2019. The weight of each soil nutrient index was determined by principal component analysis method, and the comprehensive evaluation of soil fertility was conducted by using the membership function of fuzzy mathematics. The results showed that the proportion of soil pH in the suitable range was 41.73%. The contents of available potassium and phosphorus were relatively sufficient, reaching 60.87% and 66.29% respectively in the high level range. The proportion of organic matte in the high level range was only 18.73%, slightly less than the average. The proportion of alkali-hydrolyzable nitrogen in the high level range was 34.96%. The average of comprehensive evaluation indexes of tobacco planting soil was 0.58, the coefficient of variation was 31.28%. Comprehensive fertility of 80.85% tobacco planting soils was in the medium or above level. So most of the tobacco planting soil was suitable for high-quality tobacco cultivation in Xiangyang city.
