BIOLOGICALLY ENRICHED SUBSTRATE, METHOD FOR MANUFACTURING SAME, AND ITS APPLICATIONS FOR REGULATING PIONEERED VEGETATION

摘要

This substrate consists essentially of an organic material rich in Cyanophyceae and Bryophytes combined with a non-erosive support consisting of a clay material in which the biological components are inoculated. It also comprises materials rich in organic matter, limestone amendments, dry starch and water-repellent polymers. BR/ Its manufacturing process consists in forming the first stages of colonization of Cyanophyceae-Bryophytes in hygrocline to xerophilic situation. BR/ Cyanophycea in the form of a polyspecific association and Bryophyte associations in the form of protonemas are cultivated together on a bed of clay, these two associations being in agreement with the species present in the natural environment to be regraded. drying and then grinding of this culture, it is spread on a new bed of clay for extension of the biomass to be produced then, after drying and grinding of the whole, it incorporates materials rich in organic matter, amendments limestone, starch and partially hydrated hydroretrating polymers. BR/ Application to the regradation of pioneer vegetation by inclusion in the substrate, at the time of application, a small amount of seeds of the higher plant species of the prepelouse or the lawn.
