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 experiment was conducted to study the effects of SRI seedling age, density and nitrogen application rate on the yield and its components of Liangyou Peijiu, and to establish a high-yielding rice fortification culture Optimization of agronomic measures. The results showed that the effects of three factors of density, nitrogen application rate and seedling age on yield were both significant. Rice agro-optimization system (SRI) agronomic optimization measures are: 15d seedling transplanting, planting density of 150000 cesium per hectare, nitrogen application rate of 30000kg per hectare of green manure as a base fertilizer, add fertilizers pure nitrogen 150kg.
