以黄土母质生土为材料,通过盆钵试验,研究了腐殖酸类物质风化煤与玉米秸配施在土壤熟化培肥过程中对土壤微生物量及生物活性的综合影响。结果表明,施用风化煤,特别是与玉米秸配施,对土壤生物量C和土壤呼吸强度、纤维分解强度等表征土壤生物学性状的指标均有不同程度的促进作用,互作激发效应较明显,有较好的实际应用价值。经统计优选,在本试验条件下,对土壤微生物及其活性具有较佳效应的方案为风化煤施用量24150～32400kg/hm2,同时配施玉米秸35550～41550kg/hm2,尿素1080～1290kg/hm2。
The loess parent material was used as raw material and the pot experiment was conducted to study the combined effect of humus anthracite and corn stalks on soil microbial biomass and biological activity during maturation and fertilization. The results showed that the application of weathered coal, especially with corn stalks, promoted soil biological C and soil respiration, fiber decomposition strength and other indicators of soil biological characteristics of different degrees of promotion, interaction stimulus effect is obvious , Have better practical application value. According to the statistical optimization, under the test conditions, the program with better effect on soil microbe and its activity is weighed with 24150 ~ 32400kg / hm2 of weathered coal, with 35550 ~ 41550kg / hm2 of corn stalks and 1080 ~ 1290kg / hm2 of urea .
