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。
The effects of silicon fertilizer on sorghum yield, photosynthetic rate and anti-fracture ability were studied by spraying silicon fertilizer in different periods to provide a scientific basis for the popularization and application of silicon fertilizer on sorghum. Test selection \\ \"return \\\" liquid silicon fertilizer, to take a randomized block design, a total of three treatments, each treatment 3 times repeated. The results showed that spraying silicon fertilizer could improve the net photosynthetic rate and chlorophyll content of sorghum, reduce the center of gravity and improve the anti-cracking ability of the stem, and increase the content of starch, protein and fat in the sorghum grain. Silicon fertilizer best.
