摘 要 ：为了解栽培措施对防治小麦白粉病的作用，通过不同栽培措施对病情产生不同影响的大量田间调查，明确了小麦早播、密播，过量水、肥条件下的旺苗和种植高度感病品种，都会加重小麦秋苗带菌量。短期播种、合理密植、视墒灌水、配方施肥、培育小麦壮苗及避免种植高感品种等均能减轻小麦秋苗带菌量。小麦秋苗带菌量大，则翌春病菌越冬菌源量也大。种植高感品种在田间有发病中心的作用。应把栽培防病措施规范化、科学化、制度化，以充分发

Abstract:It is ascertained that it will increase the quantity of powdery mildew of wheat seedlings in the autumn under conditions of early sowing, over-density, over-watering, over-doses of fertilizer and growing of highly susceptible cultivars through large scale
