| 摘 要： | 为了解冬闲田播种的不同种类牧草田的杂草群落发生动态，调查了30％黑麦草＋70％白三叶，30％黑麦草＋70％紫云英，30％黑麦草＋70％紫花苜蓿，3种不同牧草混播处理下冬闲田杂草的生长特点。结果表明：牧草混播种类的变化使冬闲田杂草的发生有差异，主要表现为杂草种类和危害程度不同，其中以30％黑麦草＋70％紫云英处理下的冬闲田杂草危害程度最低。

| Abstract: | In order to understand the dynamics growth of weeds during fallow winter season,experiments of forage grasses mixture were carried out：30% ryegrass mixed with 70% white three leaves （Treatment 1 ）,30% ryegrass mixed with 70% milk vetch （Treatment 2）,and 30% ryegrass mixed with 70% alfalfa （Treatment 3）.The results indicates that：weed species and damage degree of weeds of different forage grasses mixture were different.The damage of weeds in winter fallow fields was minimum under the treatment of 30% annual ryegrass mixed with70% milk vetch. |
