Substrate containing Cyanophycea and Bryophyte protonemas for producing vegetation on bare terrain

摘要

A biologically enriched substrate containing organic matter rich in colonies of Cyanophycea(cyano-bacteria, also called blue or green algae) and Bryophytes(moss) is prepared for rapid creation of natural vegetation on bare terrain. More specifically, the substrate contains 20- 30% material rich in organic matter, 40-60% synthetic polymer and 10-20% clay material inoculated with a combination of colonies of Cyanophycea and colonies of Bryophytes in the form of protonemas. The material rich in organic matter is preferably black peat, blond sphagnum bog, Briere black, composts, straw, leaves, manure, tree barks, vine shoots, marc of grapes, seaweed, wood chips, saw dust, mushroom grindings, river mud or marsh mud. The clay material is preferably montmorillonite, micaceous or kaolinite clay. The substrate may also contain starch, limestone, phosphate chalk type A, phosphate chalk type B, calcareous marl, slimy sand or polder. Seeds of a higher plant species may be added to the substrate when it is applied to bare terrain. The substrate is prepared by inoculating the clay material with the combination of Cyanophycea and Bryophytes to form a bed of inoculated clay material, culturing the combination on the bed to produce a culture, drying and grinding the culture to produce a dried culture, spreading the dried culture over a new bed of clay material to produce an extended culture, drying and grinding the extended culture and mixing the dried extended culture with the material rich in organic matter and the synthetic polymer.
