摘要

PURPOSE: a kind of soil improver, which provides, effectively restores complex area by the pollution of cation and anion heavy metal in soil, improves the growth volume of plant to reduce and absorb a large amount of heavy metal. ;CONSTITUTION: a kind of oyster shell soil improver mixing obtains having improved basicity and the weight ratio of slag is 1:9 ~ 9:1. It is a kind of to prepare soil improver, comprising steps of discarded oyster shell crushes; Remove organic material from oyster shell, and be added quick lime (CaO) or magnesia (MgO) improvement use basicity; Mix the slag of oyster shell and which quick lime addition steel production. ;The 2010 of copyright KIPO submissions
