| 摘 要： | 在河北坝上高寒地区，用替代试验（相同密度400粒／m^2下5种播种比例，6次刈割）研究了燕麦（冬牧70黑麦）＋箭舌豌豆混播草地种间竞争的动态变化，结果表明，巴燕6号燕麦（冬牧70黑麦）在混播种群落中其竞争力一直超过箭舌豌豆，箭舌豌豆处于竞劣势地位。

| Abstract: | The dynamic studies on competitive interaction between the species Avena sativa or Secale carele and Vicia sativa in mixture were carried out using a replacement series experiment (five mixture proportions, six harvest times at common density of 400 seeds/m2). The results indicated that Avena sativa L. cv. Bayan No. 6 (Secale carele L. cv. Dongmu No.70) is always superior to Vicia sativa in mixture, the latter is seriously suppressed by the former. |
