| 摘 要： | 对生物复合菌肥进行菌群的分离鉴定、含菌量的测定和比较以及菌株生物学特性的初步研究.该生物复合菌肥中含有活性较高的固氮菌(维氏固氮菌)、钾细菌和无机磷细菌,每克菌肥中细菌总数达到2.0亿～2.5亿.固氮菌在修改的Dobereiner无氮培养基上生长良好,固氮活性较强,该菌生长最适温度在20～32℃之间,生长的pH值范围是5.5～8.5,最适pH值是7.5.

| Abstract: | The microbial flora in the compound bacterial manure were isolated,identified and the amount of the bacteria determined.The physiological characteristics of the strains were studied.In the compound bacterial manure,there were potash germs,phosphate germs and nitrogen fixation bacteria(Azotobacter vinelandii) with considerable activities.The total counts in the manure reached 200-250 million per gram.The nitrogen fixation bacteria grew well,and exhibited high activity on a modified Dobereiner culture medium.... |
