摘要： 摘要：试验在内蒙古阴山北麓武川县旱作农田进行，以传统耕作为对照，研究免耕、年年深松、年年浅松、浅旋与隔年深松6种耕作方式对杂草控制以及燕麦产量的影响。结果表明：①农田中单子叶杂草所占比例大，主要有狗尾草、野燕麦等，都为禾本科杂草，占全部杂草的81.7%；其它为双子叶杂草，主要有猪毛菜、藜、黄花蒿等8种，占全部杂草的18.3%。②免耕、年年深松、隔年深松杂草发生频率较大，浅松、浅旋对杂草控制相对较好，免耕杂草密度比浅松、传统高42.4%、22.1%。③不同耕作方式结合除草剂株防效和鲜重防效均以草甘膦最高，分别达到76.3%～82.1%与79.3%～93.2%。④除浅旋外，其余耕作方式的单产均明显高于传统耕作。

Abstract: Abstract: Test in Wuchuan County in Inner Mongolia, the northern foot of dry farmland Yinshan .It carried out by Traditional Tillage as a comparison study of No-tillage, Annual Subsoiling, Annual Asamatsu, Light Rotation ,Subsoiling over year, six tillage treatment on weeds control and oat yield. The results showed that: ① It contains large proportion of monocotyledonous weeds in farmland. mainly Setaria viridis, wild oats, etc., all of them are the grassy weeds, accounting for 81.7%; Others for the dicotyledonous weeds, mainly Salsola, Chenopodium album, Artemisia annua, etc. which contains eight kinds of weeds, accounting for 18.3% of all the weeds. ②No-tillage, Annual subsoiling, Following year subsoiling in the frequency of large weeds, shallow loose and shallow rotary on the weed control is relatively good, no-tillage weed density than shallow loose, the traditional increased 42.4%, 22.1%. ③ Combination of herbicides with different tillage strains of anti-efficiency and the fresh weight control effect of glyphosate are the highest, respectively, 76.3% ~ 82.1% and 79.3% ~ 93.2%. ④ In addition to Light Rotation, all the other farming methods yields were significantly higher than traditional farming.
