| 摘 要： | 为了揭示芜湖市烟草种植区土壤肥力质量的空间变化规律，运用Fuzzy综合评判法，对芜湖市湾沚镇烟草种植基地土壤的肥力状况进行研究。共选取8个理化指标（pH、粒径、有机质、全氮、全磷、速效磷、速效钾、有效钾）对土壤养分状况进行了综合评价。结果表明：56.4%的土壤样品土壤综合肥力指数(integrated fertility index，IFI)达到了高等级，平均值为0.86，位于较高和中等级别的土壤样品所占的比例均为12.7%，其IFI平均值为0.70和0.58，二者相差不大，基本上能够满足烟草生长所需的肥力。18.2%的土壤样品位于较低的等级，IFI平均值仅为0.52，需要对其采取有针对性的措施来提高其综合肥力。

The Comprehensive Evaluation of Soil Fertility Status for Tobacco-growing Areas in Wuhu City, Anhui Province |
| |
| Abstract: | The method of Fuzzy was used to analyze the contention of soil fertility in the tobacco base in Sanyuan town of Wuhu city. Eight indicators were selected: pH, particle size, organic matter, total nitrogen, total phosphorus, rapidly available phosphorus, rapidly available potassium, and available potassium. It can be concluded that the IFI of 56.4% soil samples reached the highest level, and the average value was 0.86.The percent of the higher and middle level of soil samples were both 12.7%. Correspond, the average value of IFI were 0.70 and 0.58. The both level can satisfied the fertility need of tobacco. 18.2% of soil samples were in the lowest level, and the average value was 0.52. The situation of fertility should be improved in order to increase the amount and quality of tobacco. |
