板栗疫病与主要生境和经营因素的定量分析

应用数量化理论I模型分析板栗疫病与生境和经营因素的关系。复相关检验结果表明，板栗疫病发病率和感病指数两个数学模型均达到极显著水平；偏相关t检验表明，发病率同A层厚度、土层厚度、经营水平有紧密的相关性，与土壤质地有较紧密相关；感病指数同A层厚度、土层厚度、土壤质地有紧密的相关，与经营水平有或较紧密的相关。

A Quantitative Analysis of Cryphonectria parasitica and Primary Factors of Habitat and Management

The relation between the disease of Cryphonectria parasitica and primary factors of habitat and management was analyzed by the quantitative model I. The result of correlation coefficient test showed, the relation betwen the two mathematics models of the incidence and dangerous index of the disease was remarkable. The result of partial correlation coefficient test showed, the relations of the incidence and infected index of the disease with thickness of A soil layer, thickness of soil, quality of management, quality of soil were close or comparatively close.
