摘　　要：从供试土壤样品中筛选出几株高效解磷、解钾和自生固氮菌菌株 ,其中 ,以菌株P1 、K1 、N1 解磷、解钾和固氮效果最好。盆栽试验结果显示 :与对照相比 ,高效菌株组合P1 K1 N1 能使番茄和油菜的生物量分别提高 65 .9%和 68.4%。In this study, several bacterial stains with the function of desolving phosphorus, releasing potassium, fixing nitrogen were isolated from the trial soil samples,and bacterial stains P 1,K 1,N 1 were very effective, the results of pot cultures showed that new combination P 1K 1N 1 could obviously increase the biomass of tomato and rape compared with the controls (over 65.9% and 68.4%)
