摘要
在河北坝上高寒地区，用替代试验(相同密度400粒／m2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)在混播群落中其竞争力一直超过箭舌豌豆，箭舌豌豆处于竞争劣势地位。
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.
