FIELD: agriculture.
SUBSTANCE: invention is related to the field of forestry. Cuttings of planting stock and hydroponics channels with host material are prepared. Cuttings for rootage are placed in greenhouse gutters with polyethylene covering. Rootage stimulators are used. Flow exchange of water is created in gutters. Stimulating sprinkling of cuttings and their leaves with sugar solution creates conditions of natural sugar generation in cutting, which defines development of its rootage. Additional stimulating fertilising of cuttings is provided by leaf treatment with growth regulator spraying. Bed of hydroponics is filled with substrate from cutting wood type chips. Polyethylene film that forms hydroponics bed and maintains its permanent temperature is laid in gutters arranged in natural soil of greenhouse. Prepared cuttings of planting stock are formed in bundles in cases arranged in gutters.
EFFECT: invention makes it possible to eliminate dependence of individual peculiarities of trees and weather conditions in period of rootage and to improved yield of biennial standard seedlings.
