Yavorovsky P. The improvement of agro methods in cultivating the planting material of decorated trees

The dissertation is devoted to the improvement of agro methods in growing the planting materials of decorated woody plants, intended for greening the suburban territories of the cities, urban and suburban forests.It is shown, that the treatment by plant growing regulation triman-1 and root additional fertilizing by complex mineral fertilizers (VIDAKS-N) as well as by carbon-ammonium salts, contributes to increasing the line sizes and mass of woody plants.The application of dividend and benlat, growth stimulator triman-1, microelement mixtures, as well as a complex preparation containing triman-1,benlat and microelements, induces the increase in pine-tree germinating.It has been found, that one-year-old pine-tree and oak-tree seedlings, grown from the seeds, treated by triman-1 and with fertilizers (VIDAKS-N) are characterized by the highest biometrical indices.Adding the mixtures of carbon-ammonium salts and ammonium nitro favored to the most intensive growth of linden.A high efficiency of growth regulators triman-1 has been established when growing the adult trees in the containers.It has been found that getting dry of the root system when replanting, causes both inhibiting the process of water absorption, and decrease in leaf transpiration of woody plants.Seedlings exogenous treatment by polymeric growth regulators polystimulin K and polystimulin A-6 stabilizes water regimen, defends the root system from getting dry, decreases the transpiration intensity and unproductive respiration.The technology of preparing film forming mixtures for increasing the getting accustomed of seedlings of woody plants, has been developed.The results of visual and spectrum estimating the state and the level of the woody plant damage due to of water and mineral deficit are presented.For the first time the method for growing the seedlings of forest cultures, that makes it possible to improve essentially the quality of seedling material, is offered.
