Comparative analysis of segetal vegetation in different climatic zones of the Northern Trans-Urals

Abstract

The article presents the results on the species composition of the segetal component in different climatic zones of the Tyumen region based on an assessment of research data in the period of 2017-2019. The study of weed flora was carried out in crops of spring wheat in the Aromashevsk and Tyumen regions. The weed component in spring wheat crops is represented by species that are most often observed in these areas during phytosanitary monitoring. At the same time, the greatest variety of plant species adapted to grow in agricultural crops was recorded in the conditions of the northern forest-steppe. During the years of research, early spring segetal plants were most widespread, their number in the tillering phase of spring wheat was the highest among other biological groups. As a result of the research, it was determined that the change in the composition of the segetal component in the agrophytocenosis of spring wheat depends on the climatic and soil conditions of the study area.
