SCOTCH PINE PLANTATION METHOD Russian patent published in 1997 - IPC

FIELD: forestry. SUBSTANCE: method involves determining forest structure of given natural population by type of biological synthesis of coniferous ethereal oil; determining number of trees of pinene, intermediate and carene type of biosynthesis of ethereal oil monoterpines; grouping seedlings grown in nursery by ethereal oil monoterpine biosynthesis. During laying of plantation among seedlings of pinene and intermediate type taken in the ratio characteristic of given natural population, carene type seedlings are placed in equally spaced relation, with number of such seedlings being increased by 15-20% as compared to designed value. In the process of care clearing, trees of intermediate type least developed are removed to reach ratio of trees of each type of ethereal oil monoterpine biosythesis characteristic of forest structure of given natural population. EFFECT: increased efficiency and improved quality of pine plantations.
