1977年至1980年,山西省太阳能育种联合试验组用柱形抛物面镜对种子进行了200余次照射试验,在140个试点中获得567个数据。统计分析表明,聚焦脉冲阳光照射不同农作物的种子可获得明显的增产效果,平均增产7—10％,其中玉米平均增产7.77—8.68％,小麦增产8.1—9.83％,棉花增产12.47％。 From 1977 to 1980, the joint solar solar breeding team in Shanxi Province conducted more than 200 irradiation experiments with cylindrical parabolic mirrors and obtained 567 data in 140 pilot projects. Statistical analysis shows that the effect of focused pulsed sunlight on seeds of different crops can be obviously increased, with an average increase of 7-10%. The average yield of corn is 7.77-8.68%, that of wheat is 8.1-9.83%, and that of cotton is 12.47%.
