据《农林科技泽丛》介绍,每年地面上接收到的太阳能量约有60亿亿千瓦小时,等于目前全世界每年消耗能量的几万倍。当前农业上利用太阳能的设备,主要是将太阳辐射能转换为热能或电能。现择其要者,介绍如下。1.太阳温室:太阳温室是人们最熟悉的一种利用“热箱原理”(亦称“温室效应”)的太阳能设备。它被用来冬季种菜和早春育秧等。日本已经研制出一种以太阳能为热源、夜间严密保温的填充颗粒温室。
According to “Forestry Science and Technology Ze Cong” introduction, the annual solar ground received about 60 billion kilowatt hours, equivalent to the current annual energy consumption in the world tens of thousands of times. The current agricultural use of solar energy equipment, the main solar radiation is converted to heat or electricity. Now choose their best, introduced below. 1. Solar greenhouse: Solar greenhouse is one of the most familiar with the use of “hot box principle” (also known as “greenhouse effect”) of solar energy equipment. It is used to grow vegetables in winter and to grow seedlings in early spring. Japan has developed a filled grain greenhouse with solar energy as heat source and nighttime heat preservation.
