摘要：
PROBLEM TO BE SOLVED: To provide a control method for vegetation with native plants as dominant plants in regard to land where native plants decline due to the growth of exotic plants. SOLUTION: The control method for vegetation into land dominated by native plants from land dominated by exotic plants includes applying a salt compound of aluminum ion and/or a salt compound of iron (III) ion and/or a salt compound of iron (II) ion to soil. The applied amount of the salt compound of aluminum ion and/or the salt compound of iron (III) ion and/or the salt compound of iron (II) ion to the soil is preferably set to the applied amount having an exchange acidity y1 of 1-50 in a depth range of 20 cm or less from the surface layer of the object soil.
