摘　　要：自装载美国大豆的外轮货舱中取样,研究进口美国大豆携带杂草和杂质的含量关系：取样量为5 kg/1 000 t,是能反映进口大豆中杂草和杂质含量关系的最低取样量;把进口美国大豆杂质含量划分为〈1.5%、1.5%-2.0%和〉2.0%3个区间,其携带杂草含量和种类与杂质含量呈显著的正相关;进口大豆中携带杂草含量高的,检出频率也相对高,但检出的杂草总种类数少于杂草含量低的;杂草含量低的,检出频率也相对低,但检出的杂草总种类数多于杂草含量高的。Weeds and impurity content relationship of importing U.S. soybean were researched by taking samples from ocean shipping cargo. 5 kg sample quantity per 1 000 tons was the minimum amount of sample which can accurately reflect weeds and impurity contents. Weeds contents and species showed the conspicuous positive correlation with impurity contents by divided U.S. soybean into three intervals：〈1.5%、1.5%-2.0% and 〉2.0%. High content of weeds has a high checking frequency during importing soybean,but the checking quantity of total high content of weeds was less than low content of weeds. Low content of weeds has a low checking frequency,but the checking quantity of total low content of weeds was more than high content of weeds.
