[目的]解决重庆地区苜蓿苗期的杂草问题。[方法]选用裸燕麦、皮燕麦2个燕麦类型,通过对株数、株高、产量、杂草率等指标测定分析,从中筛选春播苜蓿伴播作物中能较好控制苜蓿苗期杂草的燕麦类型及其伴播方式。[结果]与参试皮燕麦相比,参试裸燕麦用作苜蓿播种的伴生作物更能有效地抑制苗期杂草生长;重庆地区春播苜蓿适用的伴播处理为苜蓿（15kg/hm2）＋裸燕麦（120kg/hm2）,40cm行距条播;适宜的燕麦刈割时期在5月11日～5月21日间;适宜的苜蓿刈割时期在燕麦刈割10d后。[结论]应用燕麦伴播能有效地控制春播紫花苜蓿苗期杂草。

[Objective]The aim was to solve the weeds existed in seedling period of alfalfa in Chongqing.[Method]The naked oat and common oat were selected.Through the analysis of determiners such as plant number,plant height,yield and weeds ratio,the oat type and sowing method were screened through all the accompany sowing crops to better control weeds in the seedling period of alfalfa.[Result]Compared with common oat,the tested naked oat as the companion crop of alfalfa seeding can prevent weeds more effectively;the proper companion-seeding disposal of alfalfa sowed in spring in Chongqing area was 15 kg/hm2 of alfalfa and 120 kg/hm2 of naked oat,sowing in strip in 40 cm row spacing;the proper mowing period of oat was during the time from May 11th to May 21st;the proper mowing period of alfalfa was ten days later.[Conclusion]Spring sowing oats with alfalfa can control seedling weeds effectively.
