野燕麦是世界范围的一种恶性杂草。初步统计,目前在我国危害面积已达6000万亩以上,估计可减产20亿斤左右。黑龙江省西部地区野燕麦杂草较猖獗,有的地块每平方米有这种杂草株数甚至超过保苗株数。这一恶性杂草严重地影响着农业生产。据资料介绍,每平方米有野燕麦12株时,可减产8%,当这种杂草发展到120株/米~2时,则减产30%。燕麦畏对这种杂草具有良好地防除效果。现将初步试验结果汇总如下。
Wild oatmeal is a vicious weed in the world. According to preliminary statistics, at present, the hazardous area in our country has reached more than 60 million mu and it is estimated that it will reduce the output by about 2 billion kilos. Wild weeds in the western Heilongjiang Province more rampant weeds, and some plots per square meter of this number of weeds and even more than seedlings.
