摘　　要：通过不同时期喷施硅肥,研究硅肥对高粱产量、光合速率及抗折力的影响,为硅肥在高粱上的推广应用提供科学依据。试验选用"归来"牌液体硅肥,采取随机区组设计,共设3个处理,每个处理3次重复。研究结果表明:喷施硅肥具有提高高粱净光合速率、叶绿素含量的作用,可以降低重心高度提高茎秆抗折力,提高高粱籽粒中淀粉、蛋白质、脂肪含量,其中以高粱10片叶时期喷施硅肥效果最好。Through spraying silicon fertilizer in different periods, the effects of silicon fertilizer on sorghumproduction, photosynthetic rate and flexural strength were studied, to provide a scientific basis for siliconfertilizer application in sorghum. The ＂Return＂ brand liquid fertilizer was used in the test, randomized blockdesign was adopted with a total of three treatments, and each treatment had three repetitions. The resultsshowed that： spraying silicon fertilizer on sorghum could increase net photosynthetic rate and chlorophyllcontent, lower center of gravity height to improve stem flexural strength, and raise the content of grain starch,protein and fat. The effect of spraying silicon fertilizer at sorghum 10 leaf stage was the best.
