我国加温温室蔬菜生产合理布局探讨

    AN APPROACH TO THE REASONABLE LAYOUT OF HEATING GREENHOUSE IN CHINA

    • 摘要: 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,日照时敬,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

       

      Abstract: It is not suitable to develop heating greenhuose in the high-latitudinal area of China, including the Northeast part, Inner Mongolia the northern part of Gansu Province and Xinjian Weiwuer Autonomous Region, for total solar radiation is insufficient and the air temperature is extremely low in winter, so it needs a long period to heat the greenhose. In Liao Dong penisula and Huabei Plains, though solar radiation and sunshine hours are sufficient, but the temperature is still too low in winter, to develop greenhouse on a large scale. It is possible to select some areas with favourable microclimate condition to develope greenhouses.In Jianghuai Plains, the poor sunshine is a limiting factor to vegetable production in heating greenhouse. In Huanghuai region (32°N—37°N), sunshine is enough and temperature condition is better than those in Huabei. It may be suitable to develop heating greenhouse. So Huanghuai region can be a winter heating greenhouse vegetable producing base in China.
