摘　　要：将沙漠王子+红三叶、爱森特+红三叶按100%+0%、75%+25%、50%+50%、25%+75%、0%+100%比例混播,400株/m2同比例定苗,用替代试验研究2组禾豆草种种间竞争关系。结果表明:沙漠王子+红三叶按75%+25%的比例混播时,沙漠王子的竞争力超过红三叶,而按50%+50%、25%+75%的比例混播,沙漠王子的竞争力小于红三叶;在爱森特+红三叶的3种混播草地中,爱森特的竞争力一直超过红三叶。The studies on competitive interaction between the species Lolium perenne cv.Desert prince or Lolium perenne cv.Accent and Trifolium pratense in mixture sowing lawn were carried out using a replacement series experiment,according to five mixture proportions (100%+0%,75%+25%,50%+50%, 25%+75%,0%+100%)sowing and final singling with 400 plant/m^2.The results indicated that Desert prince was superior to T.pratense if the proportion of Desert prince to T.pratense was 75%and 25%in mixture sowing;but was lower than T.pratense L.if the proportion of Desert prince to T.pratense was 50% and 50% or 25% and 75% in mixture sowing.Accent was always superior to T.pratense in mixture sowing.
