随着我省农村商品经济的发展和人民生活水平的提高,近年来,节能日光温室的蔬菜生产发展十分迅速,各地区根据本地的自然条件、生产习惯,都有适合本地区的棚型结构和茬口安排形式。总的看来,我省节能日光温室的棚型结构是由海城感王镇矮后墙、长后坡式向高后墙短后坡高棚架方向发展。实践证明,这种高棚架结构的日光温室在采光、升温、保温的性能上有很大改善。在茬口安排上也向多茬次高效益方向发展。提高节能日光温室经济效益的途径很多,而探讨安排
With the development of rural commodity economy and improvement of people’s living standards in our province, vegetable production in the energy-saving sunlight greenhouse has developed rapidly in recent years. According to the local natural conditions and production habits, all regions have suitable shed type structures and Crop arrangements form. In general, shed energy-saving greenhouse greenhouse shed structure is the sense of Wangcheng Haicheng dwarf back wall, long after the slope to the high back wall short slope high scaffolding direction. Practice has proved that this high-shelf structure of the greenhouse in the lighting, heating, thermal insulation performance has greatly improved. Arrangements in the crop also to the stubble more efficient direction. There are many ways to improve the economic benefits of energy-saving solar greenhouse, but to explore arrangements
