Abstract
This article presents the results of a study of the effect of treatment of the root system of the M9 stock with the microbiological preparation Agrinos 1, which is a consortium of natural soil microorganisms - more than 80 strains from 10 families in combination with the preparation Agrinos 2, containing a complex of bioavailable nutrients (macro-, microelements, protein, amino acids, chitin, chitosan) in order to activate metabolic processes, reduce the impact of stress on the plant. The effect of biological products on the survival rate of the stock in the nursery, an increase in the yield and standardization of offshoots, and an improvement in their biometric parameters was established.
Highlights

This article presents the results of a study of the effect of treatment of the root system of the M9 stock with the microbiological preparation Agrinos 1, which is a consortium of natural soil microorganisms - more than 80 strains from 10 families in combination with the preparation Agrinos 2, containing a complex of bioavailable nutrients in order to activate metabolic processes, reduce the impact of stress on the plant
After the pre-planting treatment of the root system of the offshoots with Agrinos-1 product containing a complex of soil microorganisms capable of assimilating atmospheric nitrogen, converting it into various chemical forms, dissolving mineral phosphates, calcium, converting them into accessible forms for plants and other microorganisms, which, in general, contributes to an increase in the availability of soil nutrients, which, in combination with the additional application of Agrinos 2 fertilizer with a complex of bioavailable nutrients, contributed to an increase in the efficiency of plant root nutrition, as evidenced by data on an increase in rootstocks survival, which was 95.2%, which is 7.7% higher compared to control
Summary
In the Russian Federation, the production of fruit planting material is currently very relevant. Special requirements are imposed on the quality of the planting material. The production of healthy, certified planting material is associated with significant difficulties associated with a certain professional training of an agronomist, as well as the soil and climatic conditions of the region. One of the most important structural units of a fruit nursery is the mother plant of a vegetatively propagated rootstock [1-5]. Along with positive qualities (early maturity, high yield per unit area), the M9 stock has a number of disadvantages. The main ones are the high requirements of plantations on M9 to soil fertility, sufficient and uninterrupted supply of moisture due to the placement of most of the roots in the upper 30-40 cm offshoot. The rootstock offshoots in the nursery are poorly rooted [6-15]
