Protein ratio in Leymus chinensis (Trin.) Tzvelev phytomass as a quality index of the forage indicators and growth ecological conditions

Abstract

L. chinensis (Trin.) Tzvelev is a valuable hay and fattening grazing plant. The paper objective is to study L. chinensis production and protein ratio in communities growing under different ecological conditions of West Transbaikalia. It was established that the leymus community primary production is 1029-2370 g/m2 a year; the aboveground phytomass is almost completely formed by L. chinensis. The biochemical composition, forage value and protein ratio of the edificator are determined by the growing conditions, and complies with regulatory indicators, in general.
