Abstract

Problems of climatic changes and questions of the use of the natural resources for creation of a food security system are discussed. It demands an involvement in the agrarian production of the cretaceous South of the European part of Russia of local vegetable biological resources and of use for this potential of natural forage grasslands of the territory. The main objective of the made researches was assessment of territorial confinedness of economic and valuable plant species and also a status and productivity of a natural forage grassland within agrolandscapes of the cretaceous South of the European Russia (the territory of the Belgorod region). Biological and vegetable resources of the natural forage grasslands of the East part of the Belgorod region in a subband of the southern forest-steppe were studied. Field geobotanical inspections of large arrays of ravine and frame complexes and meadows, of the most perspective for the organization of haymaking and pasturable economy, were realized in 2012-2018. Research stations are located in Alexeyevsky district of the Belgorod region (tab time – 2002). The climate of the studied territory is moderately continental with a big annual amplitude of temperatures, a rather soft winter with a frequent thaw and snowfalls; with the solar and long summer; moderate unstable moistening with dominance of summer rainfall. It is established that in the steppe calciphilous communities long-term herbs prevail, and bushes and trees play the subordinated role. At decrease in degree of a pasture, intensity of mowing and recreational loading. The share of wood and shrubby vegetation increases. The overground phytomass of natural forage grasslands increases in process of remoteness from settlements and decreases in economic loading. The biggest value for the livestock production has communities with dominance of Bromopsis inermis, mixed herbs and the content of bean herbs of 15-25%. The received data about productivity and biological capacity of natural forage grasslands, allows to plan their share in the haying and pasturable line during cultivation of cattle. The oveground phytomass of communities slightly changed by years of a research. Communities with dominance of Bromopsis inermis and mixed herbs – on 50-68 g/m2 are higher than the others, have the largest phytoweight. The main phytomass of hay crops consists by the types having high growth rate: Bromopsis inermis, Diplotaxis cretacea, Festuca orundinacea, Lotus corniculatus, Matthiola fragrans, Medicago falcata. Perspective forage grasslands are located in the lower slope clots. Distribution of the types by the economic value showed that cereals make 10.8-47.2%, beans – 15.1-25.1% on weight of an absolute dry material. The correlation between productivity of the overground phytomass of communities and a projective covering (r=0.736) is discovered. The use of the studied territories as forage grasslands will allow to use rationally an arable land and to reduce the price of livestock production in the Belgorod region for 15-20%.
