  • This study has approached the effect of inorganic nitrogenous fertilizer in combination with organic fertilizer on the microflorain paddy soil and enzymatic activities.The location experiments of 10 rice cropping seasons in five years showed that compared with the relative treatments of equivalent nitrogens urea, the combining treatments of urea separately with Azolla,green manure and barnyard manure revealed that soil bacteria increased by(5.46-7.28)?105, Fungi increased by(0.96-1.96)?103,Actinomycets increased by(10.06-11.30)?104,Azotobacter increased by(7.85-9.56)?104,Urease-producing bacteria increased by(5.66-7.74)?105, the content of soil Hydrogenperoxide enzymatic activities increased by(0.36-0.49)(0.1 mol/L KMnO4ml/g.mil),the content of urease activities increased by 0.83-1.63(NH3-Nmg/g.soil).Meanwhile the combining treatments also raised the nutrition providing capacity in soil and the rice productivities acquired remarkable benefit in soil ecological recycling and economical efficiency.
