Maksumchyk N. Ecology-biological and agrotechnic bases of growing of Scots pine in temporary nurseries of Kiev Polissya

Object -ecology-biological processes in the field of growing of Scots pine of in temporal nurseries. Purpose - scientific basis and development of practical bases of application of complex of agrotechnical measures, which allow intensifying the processes of growing of the planting material. Methods - for the lay a foundation of trial areas and establishment of different indexes of seedlings of pine-tree the ordinary was used by the methods of study of forest cultures. For determination of physical and chemical properties soils was used by methods soils analyses, for determination and account of exciters of illnesses of seedlings - phytopathological researches, for determination of specific composition of nematodes - nematological researches. The methods of variation of statistics were used for estimation of authenticity and features of display of the trained conformities to the law. Novelty - the staggered of seedlings of pine-tree is certain by the exciters of illnesses and exposed different types ofnematodes at roots one-year seedlings, their quantity is set. Influencing of moisten of seed is first found out in extractions of bodies of fungi on energy of germination, likeness, growth of young plants and decline of staggered. Action of stimulators and foliar top dressing seedling is set on indexes and staggered of seedlings of pine-tree ordinary. Results of researches are findings have the scientific and practical value in expansion of picture of intensification of growing of seedlings of pine-tree of in temporal nurseries. Can be drawn on results of researches for organization of mass production of seedling materials in the temporal nurseries of region. Branch - forestry.
