采用田间小区试验，研究了有机肥(稻草、猪粪、猪粪堆肥和沼渣沼液)与化肥配施对水稻光合特性、硝酸还原酶(NR)及蔗糖磷酸合成酶(SPS)活性的影响．结果表明，猪粪堆肥与化肥配施处理在提高水稻功能叶净光合速率、水稻碳氮代谢关键时期NR和SPS酶活性方面较其他类型的配施处理有较明显优势，并能提高水稻产量和改善品质．与施纯化肥相比，以20%的猪粪堆肥氮配施80%的化肥氮处理的早稻孕穗期功能叶NR酶活性提高了65.06%，蜡熟期SPS活性提高了7.70%，游离氨基酸含量提高43.87 mg/kg，产量增加19.65%．

Field plot trial was conducted to study the effects of organic manure and inorganic fertilizer combination on photosynthesis characteristics and activities of nitrate reductase （NR） and sucrose phosphate synthetase （SPS） in rice functional Leaves, by applying different combination of organic fertilizer （straw, pig manure, pig manure composting or biogas fertilizer） and inorganic fertilizer. Results showed that combination of pig manure composting and chemical fertilizer showed more advantages than the other organic fertilizers, which embo...
