Influence of chemical and biological properties under long-term applying organic manure and chemical fertilizers on fluvo-aquic soils

摘要

摘要:研究长期施用有机肥与化肥对潮土土壤化学和生物学性质的影响结果表明，有机肥和化肥均使土壤有机质、全N、全P、速效磷、速/效钾、阳离子交换性提高，增加土壤微生物数量和活性，但有机肥在培肥地力、创造有利于微生物生长繁育的土壤环境方面明显优于化学肥料。

Abstract:The influence of chemical and biological properties under long-term applying organic manure and chemical fertilizers on fluvo-aquic soils is studied.The results show that both organic manure and chemical fertilizers increase soil fertility,cation exchange capacity,exchangeable base,amount of microbe,microbial biomass C and enzyme activity,but organic manure is obviously superior to chemical fertilizer in improving soil chemical and biological characteristics.
