Determination of reserves of phytomass and circannual deposition of fast-growing wood species in central Kazakhstan

摘要

The article shows the results of the research of determination of phytomass and circannual deposition of the fast-growing wood species on the dark chestnut soils of the middle and light clay-loamy granulometric composition of the dry-steppe zone of Central Kazakhstan. The aim of the research is to study the volumes of carbon and perspective of the increase of carbon deposition in the central Kazakhstan. The object of the study is poplar crop grown on the territory of Republican State Enterprise "ZhasylAymak". The growth plots were planted for determination of phytomass. Forest crops of hybrid poplar "Kazakhstanica" in the green zone of Astana are created by the various coulisses (five-six coulisses, width of coulisses is 24 m, intercoulisse spaces are 10 m, distance of interrows is 4 m). Total mass of deposed carbon of the poplar in Republican State Enterprise "ZhasylAymak" is 0.057 tons and the phytomass reserves are 1.343 thousand tons.
