摘要
应用方差分析法,研究了不同立竹度、竹林结构、坡位、坡向、腐殖质厚度、林地卫生状况等因素与浙江双栉蝠蛾发生的关系。结果表明,立竹度、竹林结构、坡位、坡向的变化对浙江双栉蝙蝠蛾危害程度影响不明显。土壤腐殖质厚度和林地卫生状况的变化对浙江双栉蝙蝠蛾发生有显著的影响.
By applying the method of variance analytic and the relative modulus and studying the bamboo density, structure of bamboo ages, sloping position and direction, humus and the relationship between the sanitation of the forest land and the population density of Bipectilus zhejiangensis Wang, the results showed that the changes of the bamboo density, structure of bamboo ages, sloping position and direction are not efficient to the occurrence of Bipectilus zhejiangensis Wang. The change of humus and the relationship between the sanitation of the forest land are seriour effect to Bipectilus zhejiangensis Wang.
