【摘要】 以玉米做生测试材进行盆栽试验,研究萘二甲酐、对甲氧苯并呋喃、N-对氮苯磺酰基唑烷酮和农药降解菌单菌剂、复菌剂及有机处理复合剂6种除草剂"安全剂"对咪唑乙烟酸土壤残留的解毒效果。结果表明:咪唑乙烟酸有效成分用量为25、50、75ga.i./hm2,分别加入6种"安全剂"后,玉米的株高、鲜重和叶片数均高于无安全剂对照,筛选出了解毒效果较好的化学"安全剂"萘二甲酐及农药降解菌单菌剂和复菌剂。更多还原

【Abstract】 The alexipharmic effect of herbicide safeners to the imazethapyr residue in soil were made by pot trial using corn for bioassay material, 6 kinds of "safener" were 1,8-naphthalic anhydride, p-methoxy benzofurane, and N-p- nitrogen benzenesulphuracyl oxazolidone, herbicide degrading bacteria single preparation, herbicide degrading bacteria multiple preparation and organic treatment compound. The results showed that these safeners have definite alexip- harmic effect to the imazethapyr residue in soil. While using imazethapyr dosage is 25, 50, 75 g a.i./ha, adding 6 kinds safeners separately, corn plant height, corn plant fresh weight and corn leaf numbers were all higher than no safener treatment. The alexipharmic effect of 1,8-naphthalic anhydride is better than another two chemical safeners, the alexipharmic effect of herbicide degrading bacteria single preparation and multiple preparation is better than among the degrading bacteria.更多还原
