Researches regarding the use as a biomass of vines residues resulting from the dormant pruning

Abstract

At the global level, biomass is considered one of the main forms of renewable energy, as it ensures the conservation of the sun's energy in chemical form, being one of the most popular and universal resources on Earth, used for energy purposes since the discovery of fire by man. Today, biomass can be used for different purposes from room heating to the production of electricity and fuel for cars. Biomass is the biodegradable part of agricultural products, waste and residues, including plant and animal substances, forestry and related industries, as well as the biodegradable part of industrial and urban waste. Considering these elements, we can consider that vine plantations can make a significant contribution to the development of the biomass source, by using the vine ropes resulted from the cuts in the land.The research aimed the determination of the biomass potential of vine plantations, were harvested ropes from wine varieties and at different dates during plant rest to determine the evolution of their humidity. The samples were taken from the didactic resort farm "Vasile Adamachi" plantation of the University of Agricultural Sciences and Veterinary Medicine "Ion Ionescu de la Brad" of Iasi. The varieties studied were: Busuioaca de Bohotin, Cabernet Sauvignon, Feteasca Alba, Feteasca Neagra, Feteasca Regala, Muscat Ottonel, Pinot Noir and Sauvignon Petit.After the research carried out, it was found that the humidity of the strings is different, depending on the variety and the date of harvest.
