	<span style=\"font-size:14px;\">根据实践经验，从小麦种子和收割机夹带杂草种子，土壤耕作频率低、耕层浅，农民缺乏认识、管理粗放，杂草繁殖能力强等几个方面分析了淮北地区麦田节节麦的重发原因，初步探讨了采取小麦种子生产净度达标、二次净化小麦种子、加深土壤耕层、与阔叶作物轮作、引诱杂草提前萌发、小麦生育后期人工除草等农业措施进行防控，制定了节节麦的防防治阈值，达到防治阈值的田块于冬前选择有效除草剂进行科学施药控制，以阻断杂草蔓延、减轻危害，从而保障小麦安全生产。<br />
Based on practical experience, this paper analyzes the reasons for serious occurrence of <i>Aegilops tauschii</i> Coss. on the wheat field in Huaibei area from several aspects: wheat seeds and harvester carry weed seeds, the frequency of soil cultivation is low and the ploughing layer is shallow, farmers lack understanding and extensive management, strong weed reproduction ability, etc. In order to stop the spread of weeds and reduce the harm and guarantee agricultural production, this paper preliminarily discusses agricultural measures of prevention and control from several aspects: wheat seed production purity up to standard, secondary purification of wheat seeds, deepen the soil layer, rotation with broad-leaved crops, lure weed seeds to germinate ahead of time, artificial weeding in the later period of wheat growth, etc. The prevention and control threshold are established. Scientifically control weeds of the wheat fields up to standard from selection of effective herbicides and scientific pesticide application.</span>
