摘　　要：通过麦后水、旱直播稻秸秆还田与不还田试验对比,探索麦后水、旱直播稻秸秆还田与不还田之间生长差异及对产量的影响。结果表明,水直播与水直播秸秆还田在出苗与齐苗效果上优于旱直播和旱直播还田,其中,水直播最为优越;在发苗方面,水、旱直播稻在播后的前20d秧苗长势优于水、旱秸秆还田的处理,其中水直播又优于旱直播。从操作简便角度讲,旱直播比水直播省事,便于生产上操作。从水稻生长稳健、稳产角度讲,生产上应选用水直播还田操作方式。The results showed that the seedling emergence rate of in＇igated direct sowing and irrigated direct sowing plus returning straws to soils was better than tbat of dry direct sowing and dry direct sowing plus returning straws to soils. In seedling growth, the irrigated or dry direct sowing was superior to irrigated and dry direct sowing plus returning straws to soils. Dry direct sowing is easier to handle than irrigated direct sowing. The irrigated direct sowing plus returning straws to soils are recommended in the view of stable population development and yield formation of rice.
