太阳能是一种巨大的自然能源,世界各国都非常重视应用太阳能的研究。我国地处太阳能资源丰富的地区,据测算,每平方米面积上一年可以接受的总辐射能量为160～200万大卡,最少也能接受80～100万大卡。我国幅员辽阔,农村占绝大多数,而且农村障碍物少,阳光充足,因此在农业上充分利用这种取之不尽的自然能源有着广阔的前 Solar energy is a huge natural energy, all countries in the world attach great importance to the study of solar energy. Our country is located in a region rich in solar energy resources. According to the calculation, the total radiant energy per square meter area acceptable for the previous year is 160-2 million kcal, and at least 80-100 million kcal can be accepted. My country is vast with vast rural areas, few rural obstacles and plenty of sunshine, so having a vast frontier in agriculture that exploits this inexhaustible supply of natural energy
