Paulownia as power culture
Scientific Messenger of LNU of Veterinary Medicine and Biotechnologies
The interest for production of energy crops, which biomass may be used as renewable fuel have been grown in 70 years of last century after dramatically rising price of fossil fuels. The energy crops growing have been also stimulated by environmental factors and approval some International political initiatives, like White Paper for a Community Strategy and Action Plan and The Kyoto protocol. After some decreasing, the area of energy crops in EU and North America countries are stabilized. In
... stabilized. In Ukraine in the last few years there is a gradual increase of part of energy consumption of biopropellant from 1.3 % in 2008 to 3.4 % in 2018 in the general energy consumption of country. As the most widespread energy cultures biomass of that is used as a biopropellant come forward willow, saccharine sorghum and miscanthus. However, the last years industrial plantations of power direction appeared the paulownias taken under growing. This arboreal culture is mainly presented by the artificially shown out hybrid of Paulownia Clone in of Vitro 112®. Paulownia it quickly grows tree that for today occupies the first places for speeds of increase bio the masses, the not demanding to the agrotechnics growing proof to illnesses and wreckers is suitable for recultivation of exhausted and useless for the conduct of traditional agriculture of soils. It is characterized a softwood that successfully can be used also in furniture industry, green mass has high maintenance of albumen confronted with leguminous cultures. Bio mass of paulownia is suitable for the production of bioethanol (it is possible to get a to 0.5 ton of ethanol from a 1 ton of dry wood) and fuel preforms and пелет (power value 4211.1 kkal/kg). Next to that, a paulownia is a melliferous culture from honey the productivity 700 kg/hectare of ecological honey, as during growing does not require chemical treatments. A paulownia can be useful to 20–50 years. After each the offcutss, that is conducted at any time year with an interval in 4–8, a tree grows. At the proper supervision in 7 it is possible to get a 240–350 m³ of quality wood from 1 hectare. Taking into account the features of growing and power descriptions bio the masses of paulownia her growing will be rational with the aim of receipt of high-energy bio mass and commercial timber, and also as a melliferous culture.
