摘　　要：水稻强化栽培体系在马达加斯加的应用获得了较好的增产效果,近年在印尼等国以及中国都在进行试验,初步显示了较大的增产潜力,打破了在中国的较大栽培密度的传统习惯。通过适宜强化栽培技术的组合筛选和因素分析,试验结果表明:在川东南应用水稻强化栽培技术只要选用着粒数在173粒以内的组合,能获得显著的增产,提高稻谷的整精米率,降低垩白粒率,并且能省工省种,1 hm^2增收节支1250元以上。The system of rice intensification（SRI） is applied in Madagascar increase obtained good results,In recent years in Indonesia,the Philippines and other countries,as well as China are conducting tests,initial signs that a larger yield potential,breaking the larger of China＇s traditional practice of planting density. Through appropriate combination of cultivation techniques to strengthen screening and factor analysis,test results show that：In the southeast of Sichuan Province application as long as the choice of cultivation technology of rice intensification with less than 173 grains in combination were able to obtain a significant yield increase of rice milled rice rate and reduced the chalky grain rate,and can save labor and provincial species,1 hm^2 revenue and cut expenditure for more than 1250 yuan.
