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。
Through the wheat after the water, dry direct sowing rice straw and non-returning experiment contrast to explore the wheat after water, dry direct sowing rice straw and non-returning to the difference between the growth and impact on the yield. The results showed that the effect of direct seeding of water and direct seeding straw on the seedling emergence and Qi-miao effect was better than that of direct seeding and direct seeding, in which the direct seeding of water was the most superior. 20d seedlings growing better than water, dry straw return to the field, which is better than the direct broadcast of water and direct seeding. From the point of view of simple operation, dry broadcast than direct water, easy to operate on the production. From the steady growth of rice, stable production point of view, the production should be selected water broadcast back to field operation.
