20 0 1年 2月 ,日本滨松光学公司通过实验发现 ,用半导体激光照射植物 ,能加快其生长速度。据称 ,利用这一光照技术 ,水稻 70天即可成熟 ,一年能够收获五次。据这家公司公布的资料显示 ,它采用波长为 680纳米的红光作主光源 ,并以蓝色荧光灯作辅助。激光加速植物生长的机制在于 In February 2001, Hamamatsu Optical Co., Ltd. found that using a semiconductor laser to irradiate plants accelerated the growth rate. Allegedly, using this light technology, rice matures in 70 days and can be harvested five times a year. According to the company’s published data, it uses the wavelength of 680 nm red light as the main light source, with blue fluorescent lamps as a supplement. The mechanism by which a laser accelerates the growth of a plant is
