摘要
通过对雄安新区90块麦田450个样点杂草发生情况的调查,明确了雄安新区麦田杂草涉及12科17种,优势种以播娘蒿和雀麦为主,发生重度、中度和轻度发生田块比例分别为4.44%、8.89%和86.67%,明确了各种杂草发生的密度、频度和多度,并有针对性的提出了加强植物检疫和麦田杂草监测,科学分类施治;改变麦田杂草防治习惯,改春季防治为冬前防治;大力推行专业化统防统治等综合防治策略。
By investigating the occurrence of weeds in wheat field of 90 wheat fields and 450 sampling sites in Xiongan New Area, we have figured out there are 17 species of weeds in 12 families in wheat field, among which the dominant species are Descurainia sophia and brome, and the proportion of severe, moderate and mild filed field are 4.44%, 8.89% and 86.67%, we have also clearly got the density, frequency and abundance of various weeds. Based on the investigation, we put forward some comprehensive prevention strategies, such as strengthening plant quarantine and weed monitoring in wheat field, treating them scientifically by classification, changing the habit of weed control in wheat field from spring control to pre-winter control, vigorously promoting professional unified prevention.
