野燕麦是河西地区农田恶性杂草,发生历史悠久,分布广,危害严重。据在武威广场、二坝、张义和玉门市昌马、玉门镇等地调查,一般每亩有野燕麦4万至40万株,严重的达60万株以上。据1984年年初不完全统计受害面积达200多万亩,估计每年损失粮食1亿斤左右。为了防除农田野燕麦草,从1967年以来,我们先后在玉门、武威、嘉峪关、永昌、高台等县(市),从事化学防除野燕麦的试验研究。实践证明,燕麦畏是防除野燕麦的优良除草剂之
Wild oats are farmland vicious weeds in Hexi Region, which have a long history, wide distribution and serious harm. According to surveys conducted at Wuwei Square, Erba, Zhangyi and Changmen and Yumen Towns of Yumen, generally, there are 40,000 to 400,000 wild oats per acre and more than 600,000 serious ones. According to the incomplete statistics of the victimized area of more than 2 million mu at the beginning of 1984, it is estimated that about 100 million jin of grain is lost every year. Since 1967, we have conducted experimental research on the chemical control of wild oats in order to control wild oat grass. Since 1967, we have worked in counties (cities) such as Yumen, Wuwei, Jiayuguan, Yongchang and Gaotai. Practice has proved that oatmeal is a good herbicide to control wild oats
