小麦根际联合固氮菌剂是近年来我国研制成功的一种新型微生物增产剂。国营哈达图牧场1988和1989两年采用小麦根际联合固氮菌剂拌种播种的小麦,在同等条件下,均比不拌种的显著增产。 1988年在农林试验站春播的栗钙土壤地块上,以每亩125克的小麦根际联合固氮菌剂与“克丰2号”小麦拌种播种,播种前测定了土壤养份含量,播种时以没有拌固氮菌剂的“克丰2号”作对照,都没施基肥和化肥,
The rhizosphere combined azotobacter is a new type of microorganism production-increasing agent successfully developed in China in recent years. The wheat planted with wheat rhizosphere and rhizosphere combined with nitrogen-fixing bacteria in state-run Hadatou ranch in 1988 and 1989 both showed a significant increase in yield under the same conditions than those without seed dressing. In 1988, on the chestnut soil plots sowed in spring and forest experiment stations, the soil was inoculated with 125 grams of wheat rhizosphere combined with azotobacter and “Kefeng No.2” When not with azaleas agent mixed with “KF No. 2” as a control, no base fertilizer and fertilizers,
