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。
為瞭解鼕閒田播種的不同種類牧草田的雜草群落髮生動態，調查瞭30％黑麥草＋70％白三葉，30％黑麥草＋70％紫雲英，30％黑麥草＋70％紫花苜蓿，3種不同牧草混播處理下鼕閒田雜草的生長特點。結果錶明：牧草混播種類的變化使鼕閒田雜草的髮生有差異，主要錶現為雜草種類和危害程度不同，其中以30％黑麥草＋70％紫雲英處理下的鼕閒田雜草危害程度最低。

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.
