The invention provides a straw biological decomposition method by adoption of an anabaena decomposition accelerator. The method comprises the step of adding the anabaena decomposition accelerator, the anabaena decomposition accelerator is composed of, by mass, 37-49 parts of anabaena, 5-8 parts of complex microbial inoculants, 32-38 parts of cortex ailanthi and 25-29 parts of cushaw flower pollen. According to the straw which is subjected to the decomposition treatment by means of the straw decomposition method, the total carbon content is 27.3-31.2%, the total nitrogen content is 1.86-1.92%, when the decomposition is finished, C/N is 14.2-16.8, T is 0.41-0.48, the total phosphorus content is 0.149-0.164%, and the germination index of seeds can reach 109.5-113.4%; the invention further provides the application of the method in the improvement of saline-alkali soil, by means of the application, the soil salinity and soil pH can be reduced remarkably, the soil porosity can be increased, the soil bulk density can be reduced, the soil water infiltration rate can be enhanced, and the soil fertility can be enhanced.
