Taking arable albic soil of Hailin Farm, Heilongjiang Province as the research sample, under the condition of the same amount of nitrogen (combined application of organic fertilizer in autumn with chemical fertilizer in spring), we designed 5 treatments:100% organic fertilizer (T1), 30% organic fertilizer+ 70% inorganic fertilizer (T2), 20% organic fertilizer+80% inorganic fertilizer (T3), 100% inorganic fertilizer (T4) and no fertilizer (CK) to study the effects of long-term application of fertilizers on soil biological, physical and chemical properties and maize yield. The results showed that during the growth period of maize, the amount of soil microbial went up and then declined, and the application of high amount of organic fertilizer was helpful to the formation of bacteria and actinomycetes community structure, while inorganic fertilizer and no fertilizer were both suitable for the growth of fungal; combined application of organic fertilizer with inorganic fertilizer treatments had absolute advantages in improving soil enzyme activities over other treatments, which embodied concretely that the activities of urease and invertase were significantly higher than other treatments all the time, moreover, the effects of organic treatments on enhancing soil microbial biomass was clearly superior than inorganic fertilizer; combined application of organic fertilizer with inorganic fertilizer could obviously increase the contents of total and available soil nutrients, and enrich the soil fertility, while the effect of single application of fertilizer had poor consequences, and showed little difference, apart from those, the high amount of organic fertilizer could significantly reduce soil bulk density and increase soil total porosity; 2-year accumulative total corn yield of 30% organic manure (T2) was the highest, and the yield of T2 was 57.34% and 4.59% higher than T1 and T4, respectively, which meant that T2 stabilized and improved maize yield most obviously. Overall, 30% of organic fertilizer+70% inorganic fertilizer was the best fertilization pattern in this area.
