摘要
通过对太阳、地球相对位置季节变化的研究,从天文学和气象学的角度,依据有关数学、物理学原理计算出塑料棚面日光温室的设计参数。结果表明:据此建造的塑料棚面日光温室在冬季农业生产中每日可延长日照时间约为15 min,较其他日光温室日平均温度提高2—3℃,并具有较好的保温效果。
Based on the seasonal changes with opposite position changes of the sun and the earth,astronomy and meteorology knowledges, the optimal parameters of plastic greenhouse design were put up by the principles of mathematics and physics. The results indicate that this kind of plastic greenhouse can prolong the sunshine dura- tion about 15 minutes in the winter agricultural production. Air temperature of the greenhouse is higher about 2 to 3 ℃ than that of other solar greenhouses. And its thermal preservation is better.
