【目的】近年来,美国高粱开始大量进入我国,其携带的杂草种子状况尚未有相关研究。通过对进境美国高粱携带的杂草种子现状进行分析,可为出入境检验检疫机构的检疫监管和后续监测提供依据。【方法】通过对2014—2016年进境美国高粱截获的杂草种子的研究,了解其携带的杂草种子状况。【结果】黄埔检验检疫局和南沙检验检疫局从进境的美国高粱中截获的杂草种子种类共涉及19个科106种。主要包括禾本科27种、菊科14种、大戟科3种、茄科2种、苋科15种、豆科10种、蓼科7种、锦葵科4种、旋花科7种、十字花科4种、藜科4种等,其中检疫性杂草共涉及5科25种,检出率高。【结论】美国高粱携带的杂草种子数量大,种类丰富,检疫性杂草含量大,应予以高度重视。
【Objective】 In recent years, the United States began to enter a large number of sorghum into China, its status of weed seeds carried no relevant research. By analyzing the current status of weed seeds carried by the U.S. sorghum, it can provide the basis for the quarantine supervision and follow-up monitoring of entry-exit inspection and quarantine authorities. 【Method】 Through the study of weed seeds intercepted from US sorghum entering China from 2014 to 2016, the status of weed seeds carried by them was studied. 【Result】 The results showed that the species of weed seeds intercepted by the Huangpu Inspection and Quarantine Bureau and the Nansha Inspection and Quarantine Bureau from the imported U.S. sorghums involved 106 species in 19 families. It includes 27 species of Compositae, 14 species of Compositae, 3 species of Euphorbiaceae, 2 species of Solanaceae, 15 species of Amaranthus, 10 species of Leguminosae, 7 species of Polygonaceae, 4 species of Malvaceae, 7 species of Convolvulaceae, 4 species of cruciferae, 4 species of Chenopodiaceae, etc. Among them, there are 25 families of 5 families of quarantine weeds, the detection rate is high. 【Conclusion】 The weed seeds carried by the U.S. sorghum have a large number of species, abundant species and large amount of quarantine weeds, which should be given high priority.
