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。

关 键 词:一年生牧草  种间竞争  高寒牧区  燕麦  箭舌豌豆  混播草地  替代试验

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.
Keywords:annual forage crop  competitive interacting  high-cold pasturing area
