由于今年秋季小麦种植基础好,冬季气温偏高,田间湿度适宜,山东一些地方麦田杂草发生重,因此应及时防治,确保明年小麦高产稳产。据调查,今冬麦田孳生泽漆、麦家公、猪殃秧等杂草严重,杂草密度在30～120株/平方米,个别严重地块达150株/平方米以上。目前由于气温较高,麦田墒情适宜,仍有杂草出土,出苗达总出苗量的80%～90%。由于年前杂草生长量小,根不深,叶不壮,抗 Due to the good foundation of wheat planting in autumn this year, the high temperature in winter and the suitable humidity in the field, weeds in some places in Shandong are heavy, so we should take timely control to ensure high and stable yield of wheat next year. According to the survey, weeds such as Zeqi, Mai Jagong and Cephalopus japonicus are severely weeds grown in the winter wheat fields. The density of weeds is between 30 and 120 plants per square meter, and some serious blocks reach more than 150 plants per square meter. At present, due to the high temperature, suitable moisture content in wheat field, weeds are still unearthed, the emergence of up to 80% of the total emergence of 90%. Due to the small amount of weeds grown years ago, the roots are not deep, the leaves are not strong and resistant
