摘　　要：通过多年的生产实践,总结出云南早秋大麦生产中遇到的隐性灾害类型主要有渍害、冬春干旱、冻害、虫害、草害、药害、肥害等,针对性地提出了云南早秋大麦生产中应对隐性灾害的防治策略:科研部门培育丰产、高抗品种,栽培上合理灌排水,加强栽培管理,提高植株抗逆能力,应用物理防治、农艺措施和化学防治相结合的技术,防治病、虫、草、鸟、鼠害,并加强部门协作和农户培训,多措并举,将自然灾害损失降至最低。On the basis of many years of production practice,this paper summarizes the main types of unnoticeable hazards caused by waterlogging,winter and spring drought,cold,insect pest,grass,overdose of pesticides and chemical fertilizers in early autumn barley production in Yunnan Province.Accordingly,a number of strategies are proposed for preventing and controlling the unnoticeable hazards to early autumn barley production in Yunnan.They include breeding high-yielding and highly resistant varieties by scientific research departments;implementing effective irrigation and drainage and strengthening cultivation management;improving plant resistance;combining physical measures,agricultural measures,and chemical control measures to prevent and control the hazards caused by diseases,pests,weeds,birds,and rodent pests.In addition,efforts should be put on strengthening the cooperation of different departments and on training of farmers.All in all,multiple measures need to be taken to minimize the loss due to unnoticeable natural hazards.
