THE STUDY OF EVOLUTION AT THE SPECIES DACTYLIS GLOMERATA PRODUCTIVE CHARACTER UNDER THE INFLUENCE OF DIFFERENT DOSES OF SLUDGE FROM MUNICIPAL WASTEWATER TREATMENT PLANT PUBLISHEDNarcis BAGHINĂ, Alexandru MOISUC None
The Orchard grass (Dactylis glomearata, ssp. Glomerata) is a large scale plant, often exceeding 100cm in height. The stem is erect or genicular upward at the base. The shoots are bombed out and thick at the base and quickly lignify, which prevents them from falling easily (5). The Orchard grass is perennial grass forage with a great culture resisting from 5 to 8 years, depending on operating conditions, the culture area, etc. (5) By analyzing the production capacity of the species Dactylis glomerata depending on the amount of sewage sludge that has been given, we can observe an increase in its range, depending on the amount of sludge and implicitly the nitrogen given. Production of dry matter taken obtained from Dactylis glomerata biomass, under the influence of different doses of municipal sludge has the same growth curve as for the production of green mass. Plant height is also an important feature when talking about production, since this fact significantly influences production. In our case, the average height of plants varies between 88.5 cm (at the control) and 96.7 (the version sludge variant of 40t/ha) that height being registered in the biological limits described for this specie.
