摘要

Aeration and maintenance of aeration of rockwool producing media and to prevent settlement and growth of algae, bacteria moulds, and insect damage affecting rockwool - is ensured by a known prepn. that contains two kinds of bacteria and D,L-S-methyl-methionine-sulphonium-chloride. Treatment is carried out opt. even at prodn. stage with the prepn. being applied intermittently during the whole prodn. span.
