摘　　要：为探讨牧草单作、间作和混播的种植方式,比较刈割利用牧草2次后对牧草产种量的影响。试验采用特高一年生黑麦草和本地凉山光叶紫花苕1∶1、1∶3、3∶1的比例进行间作和混作,设黑麦草、苕子单作作比较。刈割利用牧草后施予草地田间管理措施,进行再生牧草生产草种的测定探究,结果看出黑麦草93.4%植株可顺利完成结实产种,各组合产种量在850.50~2 029.5 kg/hm^(2),以混作方式和单作方式产量较高,性状指标偏低线水平,说明刈后及时加强田间综合生产技术管理,是保证一年生黑麦草刈割利用后再生生产草种的必要措施。In order to study the planting patterns of monoculture,intercropping and mixed seeding,the effects of cutting and using forage twice on forage yield were compared.The intercropping and mixed cropping were carried out at the ratio of 1∶1 and 1∶3.3∶1 between the annual ryegrass and the native vetch.The results showed that 93.4% ryegrass plants could successfully complete seed production by applying field management measures after cutting,the yield of each combination was between 850.50and 2029.5 kg/hm~2,the yield of mixed and single cropping was higher,and the index of characters was lower than the line level,it is a necessary measure to ensure the regeneration of annual ryegrass seed after cutting and utilization.
