| 摘 要： | 研究了1年生人工混播草地杂草群落特性。结果表明，在燕麦、毛苕子和箭菩豌豆3组分按不同比例混播的草地中，杂草入侵强度变化很大。其中，燕麦60％＋毛苕子10％＋箭苦豌豆30％的混播草地中，杂草入侵最轻，杂草总盖度仅为牧草总盖度的37％，杂草总生物量仅为牧草总生物量的12％；燕麦50％＋毛苕子25％＋箭菩豌豆25％混播草地中，杂草入侵最为严重，杂草总盖度为牧草总盖度的76％，杂草总生物量为牧草总生物量的31％；燕麦33％＋毛苕子33％＋箭菩豌豆33％混播草地中，地上植物总生物量最大，达3．63kg／m^2，牧草鲜草产量也最高，为2．91kg／m^2， |

| Abstract: | The research of the characteristics of weed community of the mixed cropping of oat with vetch and common vetch revealed that the intensity of weed occupied was in great extent changes in different communities.The harm of the weed was the most slight in the community of oat(60%)+vetch(10%)+common vetch(30%).And the total coverage of weed accounted for 37% of the total coverage of forage.The harm of the weed was the most serious in the community of oat(50%)+vetch(25%)+common vetch(25%).The total aboveground p... |
