| 摘 要： | 施硅可提高根系对土壤水分的吸收能力,施硅伤流液量比对照区增加3.6%～9.4%;施硅可降低植株的蒸腾强度,减少植株水分蒸腾26.0%～39.7%,提高了植株体内水分的利用效率;施硅改变了玉米叶片细胞的形态结构,抑制了体内水分的渗透,明显改善了玉米植株体内的水分状况,为增加产量创造了良好的水分条件。

| Abstract: | The application of silicon increased the amount of soil water maize roots absorbed. The amount of xylem sap increased by 3.6% to 9.4% compared with the control. The transpiration rate of maize decreased by 26.0% to 39.7% and water use efficient were improved by the application of silicon. The morphology and structure of cells in maize leaves was changed and osmosis of water in plant tissues inhibited. So the application of silicon significantly improved water conditions in maize plants and created a better basis for the increase of maize crop yield. |
