摘 要:水稻旱直播是一项轻简栽培技术,可节省大量劳动力,缓解劳动力季节性紧张的矛盾,具有广阔的应用前景。为探索水稻旱直播在云南山区半山区的最佳栽培技术,以楚粳27为材料,设置覆膜与氮肥用量2个因素,研究了覆膜与否及不同氮肥用量对楚粳27产量和生产效益的影响。结果表明,F12处理(覆膜,氮肥用量为180kg/hm2)综合表现最好,增产增收效果最佳。Dry direct seeding technology is a simple cultivation technology ,it can save labor and reduce labor intensity. In order to determine the application effects of dry direct seeding technology in mountainous and mid-levels of Yunnan province, a field experiment was conducted with 8 treatments according to cover film or not cover film and different amounts of nitrogen fertilizer, using Chugeng 27 as material.The results showed that , F12 treatment (cover film, the amounts of nitrogen fertilizer is 180 kg/hm2) had the best effects on increasing grain yield and income. It could be widely used in mountainous and mid-levels of Yunnan province.
