摘要
【目的】研究野苹果林受害与苹果小吉丁及苹果腐烂病复合危害关系,为科学防控提供理论基础。【方法】以苹果小吉丁危害级别代表值(X1)和苹果腐烂病危害级代表值(X2)分别作为自变量,以野苹果受害等级代表值(Y)作为因变量,应用SPSS19.0软件,进行回归分析。【结果】苹果小吉丁危害等级代表值和苹果腐烂病危害等级代表值与野苹果受害等级代表值间有明显相关关系,这种关系可用多元回归方程表示为Y=0.973+0.398X1+0.329X2。【结论】野苹果林同时遭受苹果小吉丁与苹果腐烂病危害时,在制定野苹果林有害生物防控技术措施上,应将苹果小吉丁与苹果腐烂病均作为防治对象。
[ Objective ] The project aims to carry out preliminary research on relations of compsite damage of Agrilus mali Matsumura and Valsa mali Miyabe et Yamada in wild apple trees in the hope of providing a theoretical basis for conducting scientific and effective control of the damage . [ Method] Representative value of Agrilus mali Matsumura damage grade （X1 ） and representative value of Valsa mall Miyabe et Yamada damage grade （X2 ） were taken as the independent variable, representative value of damage of wild apple trees as the dependent variable, and regression analysis was performed using SPSS19.0 software. [ Result] The result showed that the interrelationship of both the representative value of the damage grade Agrilus mali Matsumura and Valsa mall Miyabe et Yamada with the damage of wild apple trees was evident, which could be expressed in a regression equation ： Y = 0. 973 ＋ 0. 398X1 ＋ 0. 329X2. [ Conclusion ] Agrilus mali Matsumura and Valsa mali Mivabe et Yamada should be used as control objects in taking measures on control pests of wild apple tree when wild apple tree is suffering compsite damage of Agrilus mall Matsumura and Valsa mali Miyabe et Yamada.
