摘　　要：试验研究了不同用量的猪粪氮替代化肥氮对水稻生长发育的影响。结果表明，不同用量的猪粪氮替代化肥氮不同程度地减少了稻谷的产量，但是处理之间差异并不显著，在水稻各个生育期土壤的氨态氮与硝态氮含量各处理之间差异也不显著；从水稻生长状况、产量及养分吸收状况分析，猪粪氮替代20％的化肥氮是比较适宜的，用猪粪氮替代部分化肥氮不会影响水稻对氮和钾的吸收。The effects of pig manure nitrogen replacing chemical nitrogenous fertilizer on soil nitrogen content and crop yields were studied in single cropping rice in Hubei province. The results showed that the rice grain yields had various degree reduction of output owing to pig manure nitrogen replacing chemical nitrogenous fertilizer in every treatment, but the differences were not significant be- tween treatments. Soil ammoniacal and nitrate nitrogen concentrations had no significant difference between treatments in every growth stages of rice. Considering rice growth surroundings, grain yields and nutrient uptake, pig manure nitrogen replacing 20% chemical ni- trogenous fertilizer was feasible. Nitrogen and potassium uptake in rice were not influenced by pig manure nitrogen replacing part chemical nitrogenous fertilizer.
