摘　　要：利用绿汁发酵液作为青贮添加剂研究其对水稻秸青贮品质的影响。结果表明,绿汁发酵液(PFJ)或其发酵液稀释再发酵后的绿汁发酵液(dPFJ)处理组的青贮稻秸中的pH和氨态氮水平明显低于其他处理组(P<0.05),乳酸含量显著高于其他处理组(P<0.05)。由此可见,PFJ和dPFJ能够明显地改善水稻秸青贮品质。The effect of previously fermented juice（PFJ） on the fermentative quality and changes in chemical composition during fermentation of rice straw silage were investigated.The result showed that the PFJ and dPFJ treated silages had significantly（P0.05） lower pH and ammonia-nitrogen content,while significantly higher lactic acid content compared with treatments.This study confirmed that the applying of PFJ and dPFJ improved fermentation quality of silage.
