摘　　要：从坪面养护、追施肥料、浇水、枯草层清理、杀菌剂施用、刈剪、新坪的管理等方面阐述了冷季型草坪养护中发病原因及机理。病原、感病寄主和环境条件是草坪病害发生的三个基本因素。草坪植物和病原在长期的进化过程中经过自然选择呈现一种平衡共存的状态,不少病害的发生是由于人类活动打破了这种自然生态平衡而造成的。因此,对草坪养护应达到使其有利于草坪抗病性的提高而不利于病害的发生和发展为目的。The article explains the cause of disease and mechanism in the aspects of turfgrass maintenance,using fertilisers,watering,withered grass clearing,insecticide usage,trimming and management of new turfgrass.Pathogeny,disease infecting narasitisn and environment conditions are three basic factors of turfgrass disease.Turfgrass plants and pathogeny show a kind of balanced co-existance statuo and the happening of many diseases is caused by the destroying of such natural ecology balance done by human beings.So the maintenance of turfgrass must arrive at the aim of raising the level of disease- resistance and keep out of the happening and developing of disease.
