The invention provides a straw decay agent and a corn straw turning, burying, returning and decay promoting method, and relates to the field of straw returning, and the method comprises the following steps: straw returning: from late September to early October every year, after corn is mature, harvesting by using a combine harvester with a cutting device, directly crushing the whole amount of corn straw, and uniformly scattering the crushed corn straw in the field, in the harvesting and smashing process, the straw length is controlled to range from 5 cm to 10 cm, the stubble height is controlled to be within 5 cm, efficient degradation of cellulose is achieved, degradation of lignin is accelerated, the colonization rate and the decomposition promoting efficiency of decomposition bacteria are remarkably improved, and rapid and high-amount decomposition of the corn straw returned to the field is promoted. 本发明提供一种腐秆剂及玉米秸秆翻埋还田促腐方法，涉及秸秆还田领域，包括如下步骤：秸秆还田，在每年9月下旬至10月上旬，在玉米成熟后，使用带有切割装置的联合收割机进行收割，将全量玉米秸秆直接粉碎并均匀抛撒在田间，收割
