INTENSIVE METHODS OF GROWING SEEDLINGS IN THE REPUBLIC OF KARELIA

The article discusses the prospects for using seedlings with a closed root system in the taiga zone, where, due to the short growing season, it is necessary to grow standard seedlings in greenhouse conditions. The seedlings were grown at different times and in cassettes of different volumes in a private nursery in Karelia with automatic sowing. Morphometric and weight indicators of seedlings were carried out, and it was noted that the timing of sowing affected them to a greater extent than the volume of the cassettes. It is noted that compliance with fertilizing technology, hardening and watering regimes ensured the production of standard pine seedlings during one-year cultivation. It is recommended to start the second rotation 1-2 weeks earlier for further growing of seedlings.
