摘    要:文章根据1965~2000年河北省日光温室试验观测资料及各地历年低温寡照对蔬菜的影响程度,确定了低温寡照灾害等级指标,分析了低温寡照的时空分布规律,20世纪80年代以后,河北省各市低温寡照发生次数比60、70年代明显增多;随着纬度增高,河北省低温寡照发生次数明显减少,危害程度明显减轻。

关 键 词:日光温室  低温寡照  灾害指标  蔬菜  栽培技术  时空分布规律  河北

Abstract:Low temperature and spare sunlight is one of the main disaster of vegetable production in greenhouse. It is necessary to estimate the degree of the disaster to vegetable in daily weather service. According to the observational data and the damage degree of vegetable in the past years, the grades of low temperature and spare sunlight were established. The space-time distribution results of the low temperature and spare sunlight are presented in all regions of Hebei Province. After the 1980s,the frequency that low temperature and spare sunlight occurrs increases obviously than the 1960s and 1970s.Its frequency and damage degree decrease evidently with the latitude increasing in all regions of Hebei Province.
Keywords:greenhouse      low temperature and spare sunlight  disaster grade  space-time distribution
