摘　　要：从福建省的不同土壤中 ,分离到 14株能在无氮培养基上生长良好的细菌。经固氮酶活性测定 ,得到 1株固氮酶活性高、抗逆性强的固氮芽孢杆菌 N117。利用该菌剂进行蔬菜盆栽试验 ,结果上海青、包菜、结球莴苣的产量分别比清水对照增产 40 .3%、 43.0 %、 5 5 .2 % 。The 14 strains of Bacillus that could grow well in nitrogen\|free media were isolated from the soil samples of Fujian.A Bacillus strain N117 with high N\|fixing capacity and strong adverse\|resistance was isolated by the nitrogenase activity determination.N117 could grow well at the range of pH 5-9 and 20-60℃,it could also live in organic fertilizer for a long time The yields of vegetable which were cultivated by applying N117 was remarkable increased to compare with CK Physical and chemical characters of soils were improved after applying N117.
