采用供硅处理与否的盆栽水稻作供试材料,研究了施用不同浓度SiO_2溶胶制剂对水稻增产的生理效应.结果表明,施用SiO_2溶胶制剂对水稻有明显的增产效应,不仅可增加茎秆充实度和机械组织厚度,有利于水稻抗倒伏能力的提高,而且还能改善冠层叶片的直立性,延长叶片光合功能持续时间,延缓叶片衰老速度并提高光合速率.试验还表明,以施用50 mg/L和80 mg/L的SiO_2溶胶制剂对水稻增产效果显著.

The experiment material was potted rice which was treated by silicon or not, the physiological effect of rice production by different SiO_2 hydrosol was studied. The result showed that yield of rice was significantly added by SiO_2 hydrosol, which not only increased haulm repletion and mechanical tissue thickness,and made for raising the anti-lodging ability of rice, but also improved the straighten of canopy blade, extended its time duration of photosynthesis function,and deferred its senescence speed and raised its photosynthetic rate. It indicated application of 50 mg/L and 80 mg/L SiO_2 hydrosol were the best treatment.
