野燕麦是我县农田的恶性杂草。全县每年发生面积约35万亩,每亩野燕麦平均达3～40万株,严重地块多达88万株以上。野燕麦与作物争肥、争光,受害小麦一般减产2～4成,严重地决小麦几乎绝产。人工拔除野燕麦十分困难,每亩有20～30万株野燕麦,拔除需化10～14个工日,工效低,劳动强度大,且践踏粮食又不易拔除干净。

Wild oats is a vicious weed in our county farmland. The county has an area of ​​about 350,000 mu each year, with an average of 300,000 to 400,000 wild oats per mu. As a result, there are over 840,000 serious land masses. Wild oats and crops fight fat, win glory, the wheat yield generally reduced by 2 to 4 percent, severely decided to almost absolutely wheat-yielding. It is very difficult to remove wild oats manually. There are between 200,000 and 300,000 wild oats per mu, and 10 to 14 days of labor are required for removal. The work efficiency is low, labor intensity is great, and trampling on food is not easy to remove.
