随着农业产业结构调整、土地承包及麦田化学除草大面积推广应用,麦田优势杂草危害种类发生了一些变化。目前播娘蒿、麦家公、猪殃殃等杂草在本市关中地区大部分麦田成为优势种类。同时野燕麦、看麦娘、节节麦、多花黑麦草发生范围逐渐扩大,危害程度不断加重,严重影响小麦生产安全。笔者通过对30a来麦田杂草演变过程分析,提出以农业防治为基础,以化学防治为主的综合治理对策。
With the adjustment of agricultural industrial structure, land contracting and large-scale popularization and application of wheat field chemical weeding, wheat weed species have undergone some changes. At present, sowing Artemisia annua, wheat family male, Galium aparine and other weeds in the city most of the wheat fields become the dominant species. At the same time, wild oatmeal, Ophiopogon japonicus, Arthropod Festival wheat and Lolium multiflorum grassland have gradually expanded their scope of occurrence and their harm degree has been aggravated, which seriously affects the safety of wheat production. Based on the analysis of the evolution of weeds in the field of wheat in the past 30 years, the author put forward a comprehensive management countermeasure based on agricultural control and chemical prevention and control.
