日光温室成败的关键是温室的透光和保温。我们在辽北地区推广中,紧紧抓住了这个问题,在海城市感王式日光温室的基础上,对温室结构作了八个方面的改进,定型为辽北式日光温室(如下图),适用于我省寒冷的“三辽地区”。1.将日光温室中柱提高到2.25米,向前移0.2米,使南侧面角由65度增加到70度,以克服由于太阳高度角随纬度增高而降低造成对透光率的影响。并延长后坡,增 The key to the success or failure of a solar greenhouse is its light and heat preservation. In the promotion of northern Liaoning, we firmly grasped this issue. On the basis of the sensory solar greenhouse in the city of Haicheng, we made eight improvements to the greenhouse structure, which are shaped as northern Liaoning solar greenhouse (as shown below) , Apply to our province cold “Sanliao area.” 1. Raise the column in the greenhouse to 2.25 meters and move forward 0.2 meters to increase the southern flank angle from 65 degrees to 70 degrees to overcome the impact on the light transmittance due to the lowering of the solar elevation angle with increasing latitude. And extend the slope, increase
