Brovko D. Phytomelioration of the sand soils in the Green Zone Kyiv town

The thesis is devoted to the researches and analysis of silvicultural methods of phytomelioration of sand soils in a green area of Kyiv. There are an analytical review of the literature on issues relating to the geographical distribution of sands in Ukraine and their classifications, the flow of natural overgrowing sands of anthropogenic origin, as well as methods of chemical and mechanical fixing and phytomelioration. It is established quantitative stock of productive moisture in the sand and loess loam. Results of researches showed the importance of optimizing their water-physical properties. It was found that by making local loess loam planting in the cracks, the sand, the possible seeding of scotch pine, black locust, amorphous shrub, buckthorn and red oak. It’s traced, the effect of depth wrapping of pine seedlings pine the sand and locally made in propagating crack loess loam on the survival rate of seedlings, biometric performance and fractional composition of biomass plants and established quantitative values of density of sand, for which the seedlings of pine with place significant changes in the fractional part of overground and underground organs of balance and calculated the cost of water for transpiration of pine plantations. It’s researched the influence of the length of the stem lignified willow holly, wild grapes, yellow acacia, tamarix and locally made in sand loess loam on the survival rate of cuttings on the survival cuttings, twig formation and rhizogenesis and influence on the water regime in the seedlings.
