The invention provides a straw biological decomposition method by the adoption of a lactobacillus casei decomposition accelerator. The method comprises the step of adding the lactobacillus casei decomposition accelerator, the decomposition accelerator is composed of, by mass, 3-7 parts of complex microbial inoculants, 24-36 parts of radix ophiopogonis, 15-26 parts of rape flower pollen and 22-33 parts of scenedesmus quadricauda breb, according to the straw which is subjected to the decomposition treatment by means of the straw decomposition method, the cation exchange capacity is 70.4-72.6 cmol/kg, when the decomposition is finished, C/N is 14.23-15.15, T is 0.44-0.47, the germination index of seeds is 108.6-110.8%, and the germination rate of the seeds is 83.4-94.6%. The invention further provides the application of the method in recarburization and fertilization in saline-alkali soil, by means of the application, the soil salinity and soil pH can be reduced remarkably, the soil structure can be improved, the soil pores can be increased, the organic contents in the soil can be improved, and the soil fertility can be enhanced.
