摘要:

为明确湖南邵阳市植烟土壤的养分空间分布特征和综合肥力情况,本研究采集并分析了该烟区3个植烟县的代表性土壤样品的养分含量。运用地理信息系统技术分析了土壤养分的空间变异特征,采用模糊综合评价法(Fuzzy)对土壤综合肥力进行量化分析。结果表明:邵阳市植烟区土壤酸碱度平均为pH 6.47;主要养分含量总体处于烟草适宜生长范围,但有效磷含量偏高;土壤综合肥力指数平均值为0.6374,大部分区域土壤综合肥力处于I~III级。研究表明,邵阳烟区土壤整体肥力状况良好,适宜优质烟叶生产,但需重点关注磷肥的减量施用与土壤养分的均衡管理。

Abstract:

To explore the spatial distribution characteristics of soil nutrients and the soil integrated fertility level of tobacco-planting areas in Shaoyang City, the representative soil samples had been collected from three tobacco- planting counties in Shaoyang City for nutrients detection. Geographic Information System (GIS) technology was used to analyze the spatial variation characteristics of soil nutrients, and the tobacco-planting soil integrated fertility was evaluated by Fuzzy comprehensive evaluation method. The results showed that the soil average pH in the tobacco-planting areas of Shaoyang was pH 6.47. The contents of main soil nutrients were within the suitable range for tobacco growth. However, the content of available phosphorus was relatively high. The soil comprehensive fertility index was 0.6374 and the soil integrated fertility in most area was from level I to level III. The results indicated that the soil integrated fertility in Shaoyang tobacco area was good and suitable for the production of high-quality tobacco leaves, but it was necessary to focus on the reduction of phosphate fertilizer application and the balanced management of soil nutrients.
