| 摘 要： | 比较研究了硅对杂交粳稻和常规粳稻干物质与养分积累及产量的影响,结果表明:施用硅肥对杂交粳稻增加籽粒产量、提高干物质积累量的效应大于常规粳稻;同时在促进水稻植株对N、P和K吸收的作用上,也表现出对杂交粳稻的作用较为明显,尤其对促进K的吸收,效应更为明显.杂交粳稻对硅的需求量高于常规粳稻.建议在杂交粳稻高产超高产栽培中注意硅肥的施用. |
| 关 键 词： | 硅 杂交粳稻 干物质 养分 产量 |

| Abstract: | The effects of silicon on dry matter and nutrient accumulations and grain yield in hybrid Japonica rice were studied and the results summarized below: increase in grain yield and dry matter accumulation as a result of silicon application was more remarkable in hybrid Japonica rice than in normal Japonica rice. Absorption of nitrogen, phosphorus and potassium by rice plant was enhanced by silicon application and this effect was also more obvious in hybrid Japonica rice than in normal japonica rice, especially in case of potassium. Demand for silicon was higher in hybrid Japonica rice plant. Thus, application of silicon as a prospective measure in high or super high yield culture of hybrid Japonica rice deserves our due attention. |
| Keywords: | silicon hybrid japonica rice dry matter nutrient grain yield |
