通过长期定位试验,研究了长春地区2011-2012小麦大豆轮作体系下,以菜粕堆肥、猪粪堆肥和中药渣堆肥为原料的有机无机复混肥和化肥,对小麦和大豆土壤有机碳含量、土壤全氮含量和土壤微生物量碳氮的影响。结果表明,在小麦季和大豆季,菜粕堆肥、猪粪堆肥、中药渣堆肥有机无机复混肥处理的土壤有机碳含量、土壤全氮含量和土壤微生物量碳氮均不同程度上高于化肥处理。
Through the long-term experiment, the organic-inorganic compound fertilizer and chemical fertilizer with rapeseed compost, pig manure compost and Chinese medicinal residue compost as raw materials were studied under the 2011-2012 wheat-soybean rotation system in Changchun region. The soil organic carbon content, Effects of soil total nitrogen and soil microbial biomass carbon and nitrogen. The results showed that organic carbon content, total nitrogen content and soil microbial biomass carbon and nitrogen of organic-inorganic compound fertilizer treated by rapeseed compost, pig manure compost and Chinese medicine residue were higher than those of chemical fertilizers deal with.
