本文从充分利用地区光热资源,节省能源出发,根据我国冬季总辐射,日照时数,日照百分率和日平均气温≤5℃期间的间隔日数和负积温的地理分布,提出了我国加温温室蔬菜生产合理布局的探讨.指出①东北、内蒙、甘新北部,不宜发展加温温室.②辽东半岛、华北平原,加温温室不宜大量发展,但可选择小气候条件较优越的局部地区,建造保温和透光性能好的温室群.③黄淮地区,大致在32°N—37°N范围内,适宜发展加温温室.④江淮平原.日照条件差,成为发展加温温室蔬菜生产的限制因子
Based on full utilization of regional light and heat resources and energy saving, according to the geographic distribution of winter days’ total radiation, sunshine hours, percentage of sunshine and day interval temperature ≤5 ℃ and negative accumulated temperature, It is pointed out that it is not appropriate to develop a warming greenhouse in northeastern Inner Mongolia and Gansu northern part of China.②Liaodong Peninsula and North China Plain are not suitable for large-scale development of greenhouse, but some localities with better microclimate conditions can be selected to construct thermal insulation Good light transmission greenhouse group.③ Huang-Huai region, roughly in the range of 32 ° N-37 ° N, suitable for the development of heating greenhouse.④Jianghuai Plain, poor sunshine conditions, as the development of greenhouse greenhouse vegetable production limiting factor
