摘要
针对节节麦在山西小麦主产区麦田已成为杂草优势种的现实,通过调查研究与分析,从防除策略制订入手,建立起以深翻除草、种子精选、合理密植、人工拔除及适期药防为主要措施的节节麦防除技术体系,在山西南部盐湖区、闻喜县、洪洞县、尧都区、襄汾县等地示范推广4 333 hm2,小麦平均单产6 900 kg/hm2,较对照田增产750 kg,共挽回粮食损失325万kg,增收325万元。节节麦的总防效达95%以上。
Aimed at the fact that Aegilops tauschii has become dominant weed in main wheat producing areas in Shanxi, technical system against Aegilops tauschii of deep ploughing, selected seeds, reasonable close planting, hand removal and suitable time chemical management was established through pains taking work of investigation, analysis and control. The system had been used in a total area of 4 333 hm2 in Yanhn prefecture, Wenxi county, Hongtong county, Yaodu prefecture and Xiangfen county. The average yield for these areas was 6 900 kg/hm^2, which was 750 kg higher than the control and total recover of 3 250 thousands kilograms wheat loses has been got.
