Method for sequestration and carbon sequestration of agricultural straws

The invention discloses an agricultural straw sealing and carbon sequestration method. The method comprises the following steps: step 1, straw collection; step 2, straw crushing operation; step 3, straw compression operation; step 4, drying operation; 5, curing and sealing operation; and 6, carrying out reclamation backfill operation. The method has the advantages that the agricultural straw is directly sealed and stored, the straw is derived from agricultural waste and is low in price and easy to obtain, meanwhile, CO2 trapping action is completed through respiration of the agricultural straw, energy consumption is reduced, carbon emission is reduced, the economic cost is further reduced, the straw is harmless to the environment, the chemical property of a solidified layer is stable, and the method is suitable for industrial production. In addition, the solidified layer is stable in structure, geological accidents are not prone to being caused, and sealed solid straw is greener, safer and risk-free than seal
