武乡县城关公社东村大队科研组去年进行了稻田免耕试验。试验地前年和去年都没有耕翻,对照田照常耕翻,其它管理措施一样。结果:免耕地亩产712.7斤,比对照田亩产447斤增产59.4％,每亩节省生产投资10元左右。稻田免耕的好处,一是减少了水分和养分渗漏,二是杂草少。因为落在地表的草子没有翻入土中,提早发芽长大,便于在插秧前整地时集中消灭。对于免耕后的其它增产措施,还在继续试验中。

Wuxiang County Chengguan commune Dongcun brigade research group conducted last year’s no-tillage rice paddy test. The pilot year and last year did not tillage, contrast Tianzhuo plowing, the same as other management measures. Results: No-tillage yields 712.7 kg, 447 kg more than the control field yield 59.4% yield per acre savings of about 10 yuan of production investment. The benefits of no-till rice paddy, one is to reduce the leakage of water and nutrients, the second is weeds less. Because grass fell on the ground did not turn into the soil, germinate and grow early, easy to concentrate in the field before planting eliminate. For no additional stimulation after tillage measures, still continue the experiment.
