进口大豆中杂草籽截获规律及检疫要点

目的]研究归纳进口大豆杂草籽截获规律,提高口岸杂草籽截获的目的性.方法]根据杂草籽日常截获及鉴定情况,结合山东口岸截获的实际情况进行分析总结.结果]口岸截获杂草籽主要种类数是88种,主要集中于禾本科、菊科、旋花科、豆科、蓼科、锦葵科、苋科、大戟科、藜科9个科;检出检疫性杂草籽,共计48种,主要集中在菊科、禾本科、茄科、苋科;截获较多的有齿裂大戟、假高粱、豚草、刺蒺藜草、三裂叶豚草、苍耳属(非中国种)6种杂草籽.结论]研究结果对口岸进口大豆的检疫截获及防控提供了理论和数据支持.

Intercepting Rules and Quarantine Points of Weed Seeds in Imported Soybean

Objective]This study was to summarize the interception rules of weed seeds in imported soybean,so as to improve the purposefulness of weed seed interception at the ports.Methods]Based on the routine interception and identification of weed seeds,together with the actual interception at ports in Shandong Province,the analysis was conducted.Results]There were 88 species of weed seeds intercepted at the ports,which mainly concentrated on 9 families,including Gramineae,Compositae,Convolvulaceae,Leguminosae,Polygonaceae,Malvaceae,Amaranth,Euphorbiaceae and Chenopodiaceae?48 species of quarantine weed seeds were detected,mainly including Compositae,Gramineae,Solanaceae and Amaranthaceae?there were 6 species of weed seeds interceped largely at the ports:Euphorbia dentata,Sorghum,halepense Ambrosia,Cenchrus echinatus,Ambrosia trifida,and Xanthium(nonchinese species).Conclusion]This study provided theoretical and data support for the quarantine interception,prevention and control of imported soybean at the ports.
