水气平衡栽培不同畦宽对免耕水稻经济性状及产量的影响

The impact on economic features and yield of no-tillage rice by different field width of water and air balance cultivation

为了探讨不同畦宽对免耕水气平衡栽培水稻性状和产量的影响,2007年早、晚季进行了水稻免耕水气平衡栽培不同畦宽对比试验,试验表明:水稻免耕水气平衡栽培比普通免耕栽培更有利于促进水稻根系生长和分蘖发生,增强根系活力,增加有效分蘖,明显提高水稻产量,早季增产4.1%～6.3%,晚季增产14.7%～17.7%;不同畦宽处理间的产量差异不明显。

In order to discuss the impact on economic features and yield of no-tillage rice by different field width of water and air balance cultivation, an experiment was conducted in early and late seasons in 2007. the results showed that water and air balance cultivation was in favor of root development and tiller sprouting, which could also enhance root vigor, increase effective tiller and obviously increase the rice yield by 4.1% -- 6.3 % for early season and 14.7 % -- 17.7 % for late season. But for the treatment of different field width, their yields had no obvious difference.
