据有关资料报道,一些国家已发现光波对植物发芽、茎叶的生长、叶片增大、花芽的形成和色素的生长均有重大的影响,如水稻用浅兰色乙烯塑料薄膜育秧,与无色薄膜相比,具有植株矮、分蘖多、鲜物重和干物重等优点。有色塑料薄膜,兰色的可大量透过400～500微米波长的光,而大量吸收600微米波长的光,红色塑料薄膜可以透通大量的600微米以上的波长的光,却大量吸收600微米以下的波长的光。光波的长短对植物生长影响不同,如315微米以下的光波(紫外线)几乎对所有的植物都有害,400～500微米(兰色)光波,可活跃植物叶绿体的运动,有利于植物的生长,600～700
According to relevant information, some countries have found that light waves have a significant impact on plant germination, stem and leaf growth, leaf enlargement, flower bud formation and pigment growth. For example, rice is planted with light blue vinyl film, Compared with the film, with short plants, tillers and more, the weight of fresh and dry weight advantages. Colored plastic film, blue can pass a large number of 400-500 micron wavelength of light, and absorb a large number of 600 micron wavelength light, red plastic film can penetrate a large number of wavelengths above 600 microns, but a large number of absorption below 600 microns Light of the wavelength. Light waves have different effects on plant growth. Light waves (UV rays) below 315 microns are harmful to almost all plants. Light waves of 400 to 500 microns (blue) activate the movement of plant chloroplasts and are conducive to the growth of plants. 600 ~ 700
