GROWTH AND DEVELOPMENT OF PLANTS ON PASTURES IN ARID ZONE AND QUESTION OF THEIR EXPLOITATION (ON THE EXAMPLE OF ARTIFICALLY CREATED MODELS

In the pasture problem, it is very important to takeinto account the load and time of grazing animals.  The article discusses these issues in detailand provides relevant mathematical dependencies related to their furtherdevelopment. The nature of the formation of vegetation on pastures of differentseason of use with the introduction of promising species of grass mixtures ofcereals, cereals and legumes, and cereals, wormwood and legumes of theStavropol breeding has been established. Tests were passed by grass mixtures – Agropyron cristatum L. + Agropyrum elangatum+ Bromus inermis; Agropyron cristatum L. + Festuca pratensisHuds. + Medicaga sativa L.; Agropyrumelangatum + Artemisia arenaria + Medicaga sativa L.


Keywords:

biomass, seizure (grazing), coefficient of optical density of plants, coefficient of vegetation screen, evaporation, model, factors.
