中国农科院土肥所吴观以等研究用0.25毫克/公斤的2,4—D处理胡萝卜离体根诱导结瘤,并分别接种田菁茎瘤菌（ORS_(571)）和巴西固氮螺菌,经乙炔还原活性测定表明:空白对照、2,4—D对照、接菌对照,三者之间无差异,固氮酶活性几测不出,但用2,4—D+田菁茎瘤菌的固氮酶活性比单接种田菁茎瘤菌提高16倍,而2,4—D+固氮螺菌的则比单接种固氮螺菌提高
Soil and Fertilizer Institute of Chinese Academy of Agricultural Sciences, Wu Guan and other research with 0.25 mg / kg of 2,4-D treatment of root tissue of carrot root nodulation, and were inoculated with Sesbania (ORS 571) and Azospirillum , The determination of acetylene reduction activity showed that: the blank control, 2,4-D control, inoculation control, there is no difference between the three, nitrogenase activity few can not be measured, but with 2,4-D + Nitrogenase activity was 16 times higher than that of monocotyledonous T. aureum, while that of 2,4-D + Azospirillum than that of monoclone alone
