摘　　要：通过大田对比试验,研究了底肥配施硅肥对玉米不同生育时期生理指标及产量的影响。结果表明,配施硅肥在玉米生育前期显著提高中部叶片叶绿素含量,显著改善穗位叶及穗上部1叶和下部1叶和2叶的叶向值,显著提高穗下部叶片的磷含量;在玉米生育后期显著提高叶面积指数,改善穗位叶叶向值,对玉米产量提高有一定影响。Effects of silicon fertilizer on physiological indices and yield of corn were researched under field comparison experiment. Results showed that,adding silicon fertilizer to compound fertilizer can significantly improve chlorophyll content of the middle leaves,significantly improve leaf orientation value of ear leaf and the first leaf above and the first and the second leaf below,significantly increase phosphate content of leaves below ears during earlier stage of corn growth. It also can significantly increase the leaf area index,improve leaf orientation value of ear leaf during later stage of corn growth. It had certain effects on the improvement of corn yield.
