【摘要】 选择了3株分别具有固氮、溶磷和解钾功能的产芽孢菌,利用垃圾堆肥吸附制取菌肥,并进行了盆栽试验,无论是单一菌肥还是复合菌肥,都对提高土壤中全氮、有效磷、速效钾的含量有显著的影响,菌肥的保存期均能达到国家标准的要求,有效性明显。更多还原

【Abstract】 Three strains of bacillus, which can fix nitrogen, dissolve phosphorus and potassium separately, were chosen for producing microbial fertilizers using refuse compost as carrier. Potted experiment was carried out the experiments result showed that fertilizers made from both single strain and combined strains had significant positive influence on total nitrogen, available phosphorus and quick-acting potassium contents of the soil samples. Their preservation time could meet the demand of national standard. Availability of all the microbial fertilizers is obvious.更多还原
