METHOD FOR GROWING OF KARELIAN BIRCH Russian patent published in 2022 - IPC A01H4/00 

FIELD: biotechnology.

SUBSTANCE: invention relates to the field of biotechnology. The invention is a method for growing Karelian birch, including planting two-year-old seedlings on the background soil with the application of mineral fertilizers and watering. Seedlings are planted in soil with close groundwater, and at a distance of 0.5-07 m from them, containers of 1-1.5 m³ with holes for aeration are built. During the first growing season, the containers are filled in a ratio of 5:1 with rapidly decomposing organic matter and slowly rotting material; at the beginning of the growing season of the next season, a 10-12 cm layer of compost mixture with sand is poured onto rotting organic residues, in which seedlings of vegetable crops are planted, the height of the organic layer ranges from 0.8-1.2 m. Regular watering of containers is carried out in the phenophase of intensive auxial and radial growth with the application of mineral fertilizers in the ratio N:P:K - 16:17:30.

EFFECT: method makes it possible to increase the photosynthetic surface area in the early growing season, which leads to the formation of an excess amount of assimilates, the outflow of which leads to a significant increase in the bark and the formation of structural anomalies, which increases the yield of decorative patterned wood and increases the rate of radial growth of Karelian birch seedlings.
