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,苏联用该法照射棉花、小麦、马铃薯、胡萝卜、西瓜、甜瓜、番茄等,其结果表明,棉花、水稻种子发芽率分别比对照提高22—27％、15％;甜瓜增产15—20％;瓜类和番茄幼苗经照射后产量增加91.8％,而且生育期缩短,提高了农产品 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 used this method to irradiate cotton, wheat, potato, carrot, watermelon, melon and tomato etc. The results showed that the germination rate of cotton and rice seeds increased by 22-27% and 15% respectively compared with the control; the yield of melon increased by 15-20% ; Melon and tomato seedlings increased by 91.8% after irradiation, and shorter growth period, raising the agricultural products
