野燕麦是危害小麦的一种恶性杂草。近十多年来,由于各地引调麦种频繁,缺乏严格的植物检疫制度,野燕麦已在我省迅速蔓延成灾。野燕麦不仅直接与麦苗争肥水争光气,影响小麦的生长发育,造成减产,且可夹杂在麦粒内影响品质,还是传染小麦赤霉病的中间寄主。全省已有五十多个县、市不同程度发生危害。据调查偃师、泌阳、卢氏、中牟、长葛、遂平、叶县、郑州市郊等部分麦出,每平方米内有野燕麦少则几株、几十株,多则几百株。每平方米内混生野燕麦50株的可造成小麦减产20%,200株的减
Wild oats are a vicious weed that harms wheat.

The province has more than 50 counties and cities in varying degrees of harm. According to the survey Yanshi, Biyang, Lushi, Zhongmou, Changge, Suiping, Ye County, Zhengzhou suburbs and some other wheat out of every square meter there are few wild oats, dozens of strains, as many as several hundred strains.
