苹果腐烂病的防治技术简

我国苹果产业近年得到迅猛发展，面积和产量均跃居世界第一，但受病害影响而需喷施大量化学农药，农残污染成为制约果品出口和食用安全的关键因素之一。既要控制病害又要减少用药，因而生物、物理防治在果树病害防治体系中占据愈来愈重要的地位。从苹果的腐烂病入手，主要论述腐烂病的病状、危害特征，提出一些较常用的化学防治、生物防治及相应的栽植管理技术。

Prevention and control of the apple rot disease

Apple industry is highly developed in recent years in China. The area and output are No. 1 of the world. Because of the disease and pest, the apple trees need to be sprayed with the pesticide, which results a large chemical pollution. Residual pesticide pollution becomes a leading export constraints and the key factor of food security. In order to control disease and reduce pesticide, biophysics prevention and control methods play an increasingly important role. Taking the apple rot disease as example, this paper mainly discussed the symptom and hazard characteristics, and provided some methods of chemical and biological control and plant management technologies.
