摘要: 在北京大兴区选择一普通温室大棚,观测正常管理方式下黄瓜生长期(2012年10月12日-2013年4月26日)温室大棚内的空气温、湿度数据,根据病菌侵染适宜的空气温度、相对湿度和叶片湿润时间,分析作物潜在病害的发生概率。结果表明,88.1%的潜在病害发生在凌晨和夜间,加强凌晨和夜间时段的温室管理是减少温室大棚病害发生的关键;潜在病害发生天数占观测周期内总天数的22.8%,2-4月潜在病害发生概率占全生育期的97.7%,其中3月最严重,占总量的53.3%,3月份温室大棚作物的食品安全潜在风险可能最大。研究结果可为北京地区温室大棚作物病害的管理提供科学依据。

Abstract: Experiments were carried out in a sunlight greenhouse in Daxing district,Beijing. The cucumber was cultivated by the cultural practices.Air temperature and relative humidity during the growing season(2012.10 to 2013.04)were collected.Based on the proper air temperature,relative humidity and leaf wet duration for disease infection,the probability of potential diseases were analyzed.The results showed that 88.1% potential diseases occurred in night and early in the morning.The managements during the period played a key role.The potential disease occurred days accounted for 22.8% during the experiment.97.7% potential diseases occurred from February to April.The most serious month was March,which accounted for 53.3% of the total.The vegetables from the sunlight greenhouse in March might be in the highest risk in food security.The conclusions could provide valuable information on crop disease management in greenhouse.
