| 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。

| Abstract: | 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. |
