试验表明接种固氮菌能显著提高桉树苗木的生长及苗木各器官的生物量和Ｎ含量，接种苗木高生长比对照（不接种）增加２９．８１％、叶片数增加３７．３１％、叶片干重增加３５．０１％、茎干重增加５５．５９％、根干重增加７８．９３％、总生物量干重增加５５．８９％。不同菌株的增产效果存在差异，接种催娩克氏菌的效果较接种阴沟肠杆菌的好。接种＋施Ｎ８０ｍｇ／株处理的效果优于接种＋施Ｎ３０ｍｇ／株处理的效果。接种与施Ｎ肥的分析结果表明接种催娩克氏菌的效果等于施Ｎ８０ｍｇ／株的效果。
The results showed that inoculation of azotobacter could significantly increase the growth of eucalyptus seedlings and the biomass and N content of seedlings. The height growth of inoculated seedlings increased by 29.81%, the number of leaves increased by 37.31%, the dry weight of leaves Increased 35.01%, stem weight increased by 55.59%, root dry weight increased by 78.93%, total biomass increased by 55.89%. The yield of different strains of different effects, inoculation Caesarean section delivery effect than Enterobacter cloacae good. The effect of inoculation + application of N80mg / strain was better than that of inoculation + application of N30mg / strain. Analysis of inoculation and application of N fertilizers showed that the effect of inoculation with C. lactis was equivalent to that of N80 mg / plant.
