激光是六十年代发展起来的一门新兴科学技术,它应用于农业的时间虽短,但发展较快。近年来,国内外广泛开展用激光照射作物种子和植株的研究,很多结果都表明:激光在一定剂量下能引起生物遗传变异,这一效应,被农作物育种工作者所采用,并取得了一定成绩;采用适宜的激光剂量处理种子,有提高种子的发芽率,刺激植物生长,促进发育,增加产量的效果。在医学上利用小剂量激光刺激细胞的活性,加速伤口愈合,用 Laser is an emerging science and technology developed in the 1960s. Its application to agriculture is short but rapid. In recent years, extensive research has been carried out at home and abroad on the irradiation of crop seeds and plants with laser light. Many results show that the laser can cause biological genetic variation under a certain dosage. This effect has been adopted by crop breeders and has achieved certain results ; The use of appropriate laser dose of seed treatment, improve seed germination rate, stimulate plant growth, promote development, increase the yield effect. In the medical use of small doses of laser to stimulate cell activity, accelerate wound healing, with
