野燕麦(Avena fatua L.)近年来E成为我区油菜和小麦田的恶性伴生杂草,发生危害面积占种植面积的48.7％,田间密度达15—300万株/亩,每年粮油作物产量损失在1千万公斤以上。为此,1985—1986年在油菜田进行化学防除野燕麦试验,结果简报如下: 试验区设在土地平坦、肥力一致、野燕麦发生严重分布均匀的伊犁黄油菜田。栽培管理与大田相同。小区面积15m~2,随机排列,重复3次(对照重复6次)。结果见表。试验结果经方差分析,区组间差异不明显, Wild Avena (Avena fatua L.) In recent years, E has become a vicious associated weed in rapeseed and wheat fields in our region. The harms of the damaged areas accounted for 48.7% of the acreage and the field density was between 15 and 300 million plants / mu. The annual loss of grain and oil crops In more than 10 million kilograms. To this end, 1985-1986 in the rape fields of chemical control of wild oats, the results briefing is as follows: The test area is located in the flat land, fertility, serious distribution of wild oats Yili butter vegetable fields. Cultivation and the same field management. Cell size 15m ~ 2, randomly arranged, repeated 3 times (control repeated 6 times). The results shown in the table. The test results by analysis of variance, the difference between the groups is not obvious,
