少(免)耕法的应用我国自古有之,宋代吴怿总结“地久耕则耗”的经验;农谚“宜早、宜晚、宜勤、宜懒”则是对少(免)耕法的绝妙概括。然而长期以来,农业生产上所谓“三犁九耙”、“平如镜、细如面”等不科学耕作危害匪浅,致使土壤肥力下降、水土流失等。所有这些都说明改革土壤耕作是当前农业生产的一项紧迫任务。近年来在我省国营农场迅速发展起来的少(免)耕法即是耕作改革的重要内容。 Less (free) the application of arable land in our country since ancient times, the Song Dynasty Wu Zong summed up the “long time-consuming farming is the” experience; agricultural proverb “should be early, late, should be ground, should be lazy” The wonderful summary. However, for a long time, unscientific farming such as “Sanlijiu rake” and “Pingruijing as fine as noodles” in agricultural production has done great harm, resulting in the decline of soil fertility and soil erosion. All this shows that reforming soil farming is an urgent task for current agricultural production. In recent years, the rapid development of the state-owned farms in our province has resulted in fewer (free) farming practices that are an important part of farming reform.
