THE USE OF BIOPREPARATION FOR ARTIFICIAL MYCORHIZATION SEEDLINGS OF FOREST TREE SPECIES IN NORTH – EASTERN KAZAKHSTAN
Abstract
The article presents the results of research carried out on the use of artificial mycorization of seedlings of forest tree species. The aim of the work is to study the mycotrophy of pinus sylvestris L. and betula pendula Roth. in forest ecosystems of North-Eastern Kazakhstan and mycorization of seedlings in open ground conditions. Experiments were made on 1160 seedlings of betula pendula Roth.and 1000 seedlings of pinus sylvestris L. in open ground conditions in the Shaldai branch of SFNRErtisormany " of Pavlodar region. In experimental seedlings, the survival rate in 2019 was 83.3% for betula pendula Roth., 55.2% for pinus sylvestris L., in 2020 it was 81.4% for betula pendula Roth., and 53.3% for pinus sylvestris L.
The need to study mycorrhizal formation in coniferous seedlings in forest nurseries in Kazakhstan is caused as a way to improve the quality of planting material.
