Composite snow melting agent and preparing method thereof

The invention provides a composite snow melting agent. The composite snow melting agent is prepared from 78-93 parts of composite salt, 6-23 parts of corrosion inhibitor and 1-4 parts of plant growth additive. By means of the prepared composite snow melting agent, the snow melting performance is good, corrosion to concrete and corrosion to metal are small, and growth of plants is facilitated.
