摘要
在小麦、玉米一年两熟制农田上,进行耕法定位及配合试验,试验表明,耙茬少耕的有效年限为1~2年。秋季麦前耕作可实行耙茬少耕1~2年、翻耕或深松1年的轮耕制。轮耕制较连年翻耕具有高效、争时、节能、降本、护土、增产的效果。夏玉米可免耕种植。
Tillage location test and its cooperative test in the wheat-maize double cropping field showed that the best time limit for applying disc plough was one or two years.The conventional mouldboard ploughing before planting wheat in autumn can be replaced by an alternate tillage system,disc ploughing for 1-2 years+mouldboard ploughing or deep chiselling for one year.The new tillage system can save time and energy,reduce the cost,im- prove soil fertility and increase yields.Summer maize can be cropped by no-tillage system.
