| 摘要: |
| 应用模糊聚类和统计分析方法研究了苹果叶片 P,K,Mo,Zn,Mn,Cu,B,Ca,Mg 和Fe 十种无机营养元素与苹果全爪螨和山楂叶螨危害的关系。结果表明:10种元素与不同果园或地域两种叶螨的发生比例及密度相关;在品种、树龄相同条件下10种元素含量的差异可能是制约叶螨发生的原因之一;苹果不同品种间10种营养元素含量的差异与苹果全爪螨密度有关;Mo,Fe,Mn 和 K 可能是影响两种叶螨发生危害的重要营养元素,它们在叶片上分布的不均匀性可能是导致两种叶螨在同一叶片上生态位分离的主要原因。 |

| Abstract: |
| Fuzzy cluster-and statistics-analysis were used to study the effect of 10 inorgano-trophic el- ements P,K,Mo,Zn,Mn,Cu.B,Ca,Mg.Fe of apple leaf on two leaf mites Tetranychus viennensis Zacher and Panonychus ulmi(Koch).The results of the analysis were as follows:there are relationship between the 10 elements and densities and proptions of the mites that live in different areas:mites densities are re- lated with the 10 elements of the same age and variety of apple tree:certain relatedness exist between P. ulmi... |
