两种联合固氮菌剂对玉米的拌种试验

Experiment of Dressing Maize Seeds Separately with Two Formulations of Synaptic Nitrogen Fixation Bacteria

用田菁茎瘤固氮根瘤菌与肺炎克氏杆菌分别拌种玉米，结果，玉米分别增产１５３％和１０２０％。每公顷７．５ｋｇ菌剂与每公顷施６００ｋｇ碳酸氢铵增产效果基本相同。

Dressing maize seeds separately with Azorhizobium caulinodans ORS 571 and klebsiella sp lead to yield increase of 15.3% and 10.2%. The results are just the same as applying Nitrogen fertiltzer.
