摘　　要：以两优培九为试验材料,采用正交试验设计方法,研究了水稻强化栽培体系(SRI)秧龄、密度、施氮量等三因素三水平对两优培九产量及其构成因素的影响,建立高产的水稻强化栽培农艺措施的优化方案。试验结果表明,密度、施氮量、秧龄三因素对产量影响均达极显著水平。水稻强化栽培体系(SRI)农艺优化措施是:15d秧龄移栽,密度为每公顷栽150000丛、施氮量为每公顷在30000kg绿肥作基肥的基础上,加化肥纯氮150kg。The optimization of high-yield cultural practices under the system of rice (Oryza sativa L.) intensification was carried out in farmer's field at Xianju in Zhejiang, used a super hybrid rice (Liangyoupeijiu) as material on orthogonal design (three factors and three levels) in the experiment. The results indicated the effects of major cultural practices of transplanting seedling, transplanting density, chemical N fertilizer input on the grain yield and its components significantly. The optimization of high-yield cultural practice under the system of rice intensification was: seedling of 15d from sowing date to transplant, transplanting density of 150000 hills/hm2, and total N application of 150kg/hm2 under basic fertilizer of 30000kg/hm2 green manure.
