紫外光对农作物有多方面的生理效应。据我们多年试验结果,经紫外光处理后的水稻种子,发芽率提高,根系发育较好,分蘖较多,穗型增大,后期茎叶清秀,不易早衰。据1986年滇榆1号品种试验结果,处理后发芽率提高9％,处理区一穴7穗、比对照多1.1穗,每穗93.1粒,比对照多18.1粒,绿叶数3.6片,比对照多1.3片,单穴粒重12.8克、比对照提高68.6％。又具两年来采用滇榆1号、晋红1号、云粳5号等10
UV light has many physiological effects on crops. According to our many years of test results, after UV treatment of rice seeds, increased germination rate, better root development, more tillers, panicles increased, the late leaves handsome, not easy to premature aging. According to the test results of Dian Yu 1 in 1986, the germination rate increased 9% after treatment, and one panicle 7 spikelets in treatment area, 1.1 spikelets per panicle, 93.1 spikes per panicle, 18.1 more spikes than the control and 3.6 green leaves, More 1.3 tablets, single grain weight 12.8 grams, 68.6% higher than the control. In the past two years, Yunnan Dian 1, Jinhong 1 and Yunjing 5 have been adopted
