利用太阳能照射种子是近年来兴起的一项简便而有效的种子处理方法。目前,苏联用此法照射棉花、水稻、小麦、马铃薯、胡萝卜、西瓜、甜瓜、番茄等。结果表明,棉花、水稻种子的发芽率可以分别提高22～27％和15％,甜瓜产量增加15～20％;瓜类、番茄幼苗经照射后产量增加 The use of solar energy to irradiate seeds has emerged as a simple and effective seed treatment method in recent years. At present, the Soviet Union uses this method to irradiate cotton, rice, wheat, potatoes, carrots, watermelons, melons and tomatoes. The results showed that the germination rate of cotton and rice seeds increased by 22 ~ 27% and 15% respectively, and the yield of melon increased by 15 ~ 20%. The yield of melon and tomato seedlings increased after irradiation
