在川西稻麦生态区进行水稻强化栽培体系 (SRI)研究 ,首先要考虑结合耕作制度 ,选用具有较强感温性的杂交中稻中熟组合 ,通过迟播、旱育秧、幼龄 (2叶 )单苗稀植 (9.0万穴 hm2 )、控水等措施 ,全生育期 13 1～ 13 2d ,穗粒结构合理 ,比相同组合常规栽培增产 6.4%～ 16.3 % ,比迟熟组合汕优 63的SRI栽培增产 3 .8%～10 .5 % ,可扩大示范与深入研究 In the rice-wheat eco-region in western Sichuan, SRI research should first consider the combination of farming system, selection of mid-season hybrid rice combination with strong temperature sensitivity, late-sowing, drought- (90,000 acre hm2), water control and other measures, the whole growth period of 13 1 ~ 132 days, grain structure is reasonable, than the same combination of conventional cultivation yield 6.4% ~ 16.3%, than the late combination of Shanyou 63 SRI cultivation yield 3. 8% ~ 10 .5%, can expand demonstration and in-depth study
