摘要
对地膜中2种酞酸酯类化合物DBP和DEHP在土壤和大豆植株体内的残留进行了研究。结果表明：常规地膜用量在播种后30-90d土壤中DBP和DEHP含量分别在0．174-0．274mg·kg^-1和2．886-2．952mg·kg^-1；大豆植株体内DBP含量在0．319-1．646mg·kg^-1，90d后随株体生长DBP含量降低，DEHP在大豆植株体内未检测到。使用地膜对大豆的生长发育影响不明显，地膜用量对大豆生长、产量、蛋白质、脂肪和水分含量影响不显著。
The content of two phthalic esters,the DBP and DEHP,in soybean plant and soil under covering was studied. The result showed that the DBP content in soil was between 0. 174-0. 274 mg ~·kg^-1 ,and the DBP between 2. 886- 2. 952 mg ·kg^-1 30 to 90 days after seeding under covering;The former content in soybean plant was between 0. 319- 1. 646 mg·kg^-1 ,then 90 days after seeding,its content decreased as the plant grew while DEHP disappeard. The research suggested the covering took no obvious effect on soybean growth;Amount of covering did not affect its growth,produc tion, contents of protein, fat, and water.
