- Abstract
Data on the species and quantity composition of weed plants in wheat agrophytocenosis are given, depending on agroclimatic conditions. Features of changes in the composition and abundance of different biological groups of weed plants during the vegetative period are considered. During the years of research in the field of spring wheat, there were 16 species of weed plants belonging to 11 families. The seasonal dynamics of the weed component is analyzed depending on the biological characteristics of weed plants, the development phase of the cultivated plant and the weather conditions of vegetation. The degree of contamination of wheat agrophytocenosis during three years of research was determined, which amounted to 10.8% (2001), 3.7% (2002) and 21.9% (2003). It is determined that the composition of the flora of weed plants is affected not only by biological features, but also by weather conditions. Weather conditions determine the massive appearance or disappearance of species of weeds. The dominant species of weed plants in wheat agrophytocenosis are established. The accumulation of dry mass by weeds was studied, as well as the relationship between the biomass of weeds and cultivated plants and their numbers.
