为了解东圣宝液体有机肥对水稻秸秆腐熟的施用效果，以东圣宝液体有机肥为基肥，施用量分别为9、15、30 t/hm2，以施化肥作对照，研究施用东圣宝液体有机肥后秸秆的腐熟程度及土壤理化性质的变化，为该微生物有机肥的产品化和合理施用提供理论依据。结果表明，在施肥15 d后，施肥量为30 t/hm2的处理，水稻秸秆腐熟最快；且土壤中氮、磷元素含量与对照无显著差异；而钾含量显著高于对照，其钾元素含量为124.50 mg/kg，对照为61 mg/kg，约是对照的2倍；该处理中的有机物含量也显著提高。研究表明，东圣宝液体微生物有机肥对加快水稻秸秆腐熟具有显著作用。

In order to understand the composing effect of Dongshengbao liquid fertilizer on rice straw,four treatments were set using Dongshengbao liquid organic fertilizer as basal fertilizer,and the applying amounts were 9 t/hm2,15 t/hm2,30 t/hm2,with fertilizer as control. The changes in the degree of maturity of rice straw and soil physical and chemical properties after applying liquid organic fertilizer were studied,so as to provide a theoretical basis for the rational application and products of Dongshengbao liquid organic fertilizer. The results showed that the rice straw the treating with 30 t/hm2 fertilization decomposed the fastest in 15 days,the contents of N and P in soil was no significant difference with the control,the content of K was significantly higher than the control. The content of K was 124.50 mg/kg in 30 t/hm2 fertilization treatment,which was about twice as much as the control(61 mg/kg),and the organic content of treatment was also significantly increased. The research results indicated that Dongshengbao liquid organic fertilizer played a significant role in accelerating the composing of rice straw.
