2012—2014年连续调查表明,冀西北亚麻田杂草种类约33种,隶属于15科。以狗尾草、藜、卷茎蓼、萹蓄、野黍、苦荞、苣荬菜、草地风毛菊等为优势种群。同一生态区域不同年份、不同地势杂草群落结构存在差异。近年来亚麻田狗尾草、野黍、苣荬菜、草地风毛菊等杂草比例上升,传播蔓延加快。根据亚麻与杂草生长指标对比,亚麻田除草最佳时期为亚麻苗期株高6~8 cm时。通过采取农业措施及化学防除相结合的综合防治技术,可有效控制亚麻田草害发生与危害。
A continuous survey from 2012 to 2014 showed that there were about 33 species of weeds in the northwestern Hebei Province, belonging to 15 families. The dominant species were Setaria viridis, Quinoa, Polygonum convolvulata, Artemia, wild millet, Tartary buckwheat, Sonchus sieboldii, The same ecological region in different years, different topography weed community structure differences. In recent years, flax field flamingos, wild millet, endangered cabbage, grass toadstool and other weed proportions increased, the spread of spread accelerated. According to flax and weed growth indicators comparison, the best weed flax field for seedling height of 6 ~ 8 cm. Through the adoption of agricultural measures and chemical control combined with a comprehensive prevention and control technology, can effectively control the occurrence of flax crop damage and hazards.
