| 摘 要： | 施用多效硅肥可以明显增加单位面积上群体的总颖花量和结实粒数；提高成穗率；提高叶面积指数、粒/叶和粒重/叶；显著提高花后干物质的生产积累能力；改善茎系结构，提高抗倒伏能力，从而使群体质量明显提高。研究结果表明，150 kg/hm2硅肥作基肥和分蘖肥对水稻群体质量和产量的影响效应较好,而拔节期不同硅肥用量中以225 kg/hm2效果最好。 |
| 关 键 词： | 硅肥 水稻 群体质量 产量 |

| Abstract: | The result of using Si in rice showed that (1)Obviously adding gross flower number and grain.(2)Raising rate of effect ear.(3)Improving maxmum LAI, grain-leaf area ratio(grain/cm2) and leaf weght(mg/cm2).(4)Obviously raising accumulated dry matter after anthesis(5)Improving structure of stems and enhancing energy of autilodge.Thereby the population quality obviously improved.It was shown that the silicon fertilizer amount of 150kg/hm2 applied as the basic or tillering fertilizer was better for population quality and yield and that 225 kg/hm2 among the different silicon fertilizer amount at jointing stage for population quality and yield was best. |
