| 摘 要： | 目的]为免耕强化栽培在水稻种植中的应用提供参考。方法]以两优培九为供试品种，以免耕抛秧栽培为对照，采用随机区组设计，通过田间试验研究了免耕强化栽培条件下水稻的生长状况和产量。结果]免耕水稻强化栽培体系（SRI）和对照在分蘖高峰期的平均分蘖数分别为36．5和26．7个／株，相差36．7％；在成熟期的有效穗数分别为14．6和11．4个／株，相差28．07％．在分蘖期、抽穗期和成熟期，免耕SRI的根系活力分别比对照高17．43％、13．63％和22．41％，叶片脯氨酸含量分别比对照高21．37％、32．44％和9．92％，叶片丙二醛含量分别比对照高10．42％、13．62％和9．47％。与免耕抛秧栽培相比，免耕SRI的有效穗数减少了8．93％，穗粒数增加了11．32％。结论]免耕强化栽培是一种高产高效栽培模式，值得推广和应用。
