METHOD FOR INCREASING INFECTION LODGING RESISTANCE OF PINE AND SPRUCE SPROUTS AND SEEDLINGS (VERSIONS)

FIELD: forestry. SUBSTANCE: method involves presowing treatment of pine and spruce seeds by exposing them to superhigh frequency electromagnetic field within frequency range of 0.5-10 GHz at intensity of 0.3-1.0 W/cm for 5-30 s before stratification laying process or presowing treatment of pine and spruce seeds by exposing them to extremely high frequency electromagnetic field within the frequency range of 20-100 GHz at intensity of 0.1-1 microW/cm for 5-20 min after stratification laying process. Method takes into account agronomic procedures of presowing preparing of said seeds, i.e. stratification thereof during 1-2 months before sowing process. Method uses ecologically clean technology allowing resistance of pine and spruce sprouts and seedlings to lodging caused by pathogenic fungi of Fuzarium kind to be increased. EFFECT: reduced production costs and increased efficiency. 3 cl, 2 dwg, 1 tbl
