A nano pore channel-type natural slow and controlled release carrier material and a preparation method therefor; the method comprises: using shrimp and crab shells and other products having natural nano-pores as carriers, and producing, directly or by means of a co-production process, a series of slow and controlled-release carriers of functional chemical substances having natural nano-pores. The described carriers can be used for the slow-release and controlled-release of medicines, pesticides, plant growth regulators, and long-lasting fertilizers, and are protected by virtue of nanopores inaccessible to microorganisms so as to avoid decomposition or loss caused by enzymes or microorganisms. |
