摘要
为给节节麦的研究提供帮助,通过现有资料的分析整理,对我国冬小麦田节节麦的起源、分布、生物学特性、与作物的竞争关系及防除研究进展进行述评。结果表明,我国冬小麦田的节节麦与中东节节麦同源;主要分布于我国黄河流域冬小麦主产区的大、小麦田;可与作物竞争水分、光、养料和空间,还是小麦条锈病菌和吸浆虫的禾草寄主;植株分蘖能力强、靠种子传播;节节麦种子的发芽主要受温度、水分影响,光照、土壤pH值、盐分对其影响不大。目前,生产上对节节麦的防除主要通过阻止传播、人工拔除与甲基二磺隆喷雾防除,效果差、防除成本高,应加强新的防除手段和途径的研究。
The origin, distribution, biological characteristics and competition mechanism with other crops, transmission, and control ofAegilops tauschii were reviewed to provide help to Aegilops tauschiicontrol in wheat fields. Results showed that, Aegilops tauschii in wheat fields of China was homologous with that in the Middle East. They are mainly distributed around the globe in latitude 30° - 45°. Seed germination ofAegilops tauschii is mainly affected by temperature, light, soil pH, moisture, but salinity has little effect. Currently production control is mainly by blocked dissemination of A egilops tauschii, manual uprooting and herbicides. We should strengthen the study on ecological control techniques of weeds, response of Aegilops tauschii on farmland ecological system resource fluctuations, the allelopathy mechanism ofAegilops tauschii, development and application of biotechnology, and research and development of low cost, efficient and safe herbicides.
