INFLUENCE OF VARIOUS BIOLOGICAL PREPARATIONS ON THE PHYSIOLOGICAL GROWTH OF PINUS SYLVESTRIS L., LONICERA EDULIS L. ZHANE RUBUS IDAEUS L. UNDER THE CONDITIONS OF COMMON CHERNOZEM OF NORTHERN KAZAKHSTAN

Abstract

The article presents the data of a research work carried out to study the effect of biological preparations «Agro-MIX», «Agrarka» and Epin on the physiological growth of the species Pinus sylvestris L., Lonicera edulis L. and Rubus idaeus L.The studies were carried out in the forest nursery Branch «Northern Region» of the Republican State Enterprise «Republican Forest Selection and Seed Center» (BNRof the RSE "RFSSC") located in the city of Schuchinsk, Burabay district, Akmola region.The information provided is obtained from studies conducted in 2021-2022. In 2021, planting and sowing sites and materials have been prepared.In 2022, planting and sowing was carried out from the second half of May. This year, data from physiological, phenological, biochemical and soil methods were collected and processed throughout the growing season.The species of the studied families were sown and planted on a total area of ​​0.4 ha. In 2022, 20 kg of Pinus sylvestris L. seeds were sown on an area of ​​0.2 ha, 2,000 rooted cuttings of Rubus idaeus L. were planted on an area of ​​0.1 ha, and 2,000 unrooted cuttings of Lonicera edulis L. were planted on an area of ​​0.1 ha.To assess the biochemical activity in the leaves of seedlings and needles of seedlings, samples were collected and the content of chlorophyll was studied using the MINI-PAM II device.
