Complex assessment of lawn grass stand of different functional purpose

The research objective was complex assessment of the quality of lawn herbages of different function created grass mixtures, presented in retail distribution network of Ulan-Ude. The experiment was put on Agroengineering ground of the FSBEI HE Buryat SAA (m. Gurulba) in 2016. For the study 10 grass mixtures were taken. The area of the allotments was 2 sq.m, the frequency was triple. The crops - at the end of the first decade of July manually with the seal by a rake and skating manual skating rink, the norm of seeding of 20 g/m2. The accounts and supervision were carried out by the standard techniques. The quality of lawn herbages was estimated on a complex 30-mark scale taking into account the density and general decorative effect. It was established that the presented range of grass mixtures allowed creating the coverings of all main groups: decorative, sports, special. Specific structure of the studied grass mixtures in general corresponded to the range of the lawn herbs for the first zone (damp, cold or moderately warm) to which the territory of the republic belongs, and was presented by 3-6 species of cereal (Poaceae) herbs. One grass mixture contains 10% small white clover. It is noted that the composition of the studied grass mixtures includes pasture ryegrass, which, under the conditions of the region, falls out of the grass stand for 2-3 years. But its inclusion in the composition of grass mixtures is justified by its rapid development in the sowing year, which reduces weed infestation of crops. As a result of integrated assessment, it was found that after three years the grass mixtures Sibiryak, Gazon dlya solnechnykh mest, Euro-len, Pridorozhnaya formed the grass stand of mediocre (8-12 points), and the grass mixtures Euro-gnom, Gorodskaya, Universalnaya - of satisfactory quality (16 points). The grass stand with good quality (assessment of 20 points) was formed by the grass mixtures Sport, Euro-universal, and Euro-sport.
