Эколого-географическое обоснование формирования видового состава сорных растений на территории Свердловской области

Abstract

In the protection of cultivated plants is of great importance to develop multi-year forecast of weed distribution in the regions. The purpose of the study was to identify the types of weeds, for which the territory of Sverdlovsk region is suitable in terms of heat and humidity. The method of ecological-geographical analysis of the simulated complex of the 113 species of weeds, for which the territory of the Sverdlovsk region suitable conditions of heat and humidity, as well as 14 species for which this area is partially suitable. The species occurrence on the territory of Sverdlovsk region species of weeds are included in the simulated prognostic complex, was confirmed by the data of scientific publications and private studies. For farmers and crop areas it is important to know that the identified 127 species of weeds are the basis for the formation of contamination of crops (planting) in the Sverdlovsk region, and the decrease in the level of technology of cultivation of agricultural crops, widely spread in agro-ecosystems.
