摘要
对收集的 10 0份龙岩烟区植烟土壤样品 ,应用计算机系统确定 4项主要的土壤养分指标进行聚类分析 ,形成龙岩植烟土壤的系统分类。聚类分析结果表明 ,龙岩烟区植烟土壤可以分为四大类 :( 1)中等肥力土壤类型 ;( 2 )高磷土壤类型 ;( 3 )高氮高钾高肥力土壤类型和 ( 4)
major indicators of soil nutrients in 100 samples collected from tobacco planting soil in Longyan were analyzed using cluster analysis method with the computer system. A classification system of tobacco planting soil was established. The results indicated that the tobacco planting soil in Longyan could be divided into 4 groups: 1) a middle fertilization soil; 2) a high phosphorus soil; 3) a high nitrogen and potassium soil; and 4) a high nitrogen middle fertilization soil.
