| 摘 要： | 采用主成分分析方法对多点动态肥料试验聚类分析结果与土壤养分间的关系进行了研究。结果表明,土壤氮素状况是分类的第一主因子,磷素状况是第二主因子,有机质含量是第三主因子。确定类肥料效应函数应用范围的主要依据是土壤碱解氮和全氮含量,其次是土壤有效磷含量,再次是土壤有机质含量。 |
| 关 键 词： | 多点肥料效应函数方程 土壤养分 动态聚类 主成分分析 |

| Abstract: | Main component analysis was adopted to study relationship betwee n soil available nutrients and dynamic cluster classification of fertilizer respon se function derived from dispersed fertilizer experiment. Results indicated that soil N content is the determined factor of classification, soil available P con tent is the second classification factor and soil available K content is the thi rd classification factor. Therefore, the main classification basis to define fea sible area of cluster fertilizer response function is the contents of soil alkal i hydrolyzed N and total N, the content of soil available P is the second and th e content of soil available K is the third classification basis. |
| Keywords: | Equations of dispersed fertilizer response function Soil available nutrients Dynamic cluster analysis Main component analysis |
