FIELD: agriculture. ^ SUBSTANCE: method involves forest regeneration felling, removal of trees felled outside the site and peripheral ridging of the silvicultural area. After the site peripheral ridging, in winter, one performs freezing of an iced stratum of liquid manure, its upper level being above that of the felled trees stumps. Then one provides for thermal insulation of the iced stratum with the iced stratum volume and the thermal insulation value ensuring preservation of the iced stratum on the silvicultural area soil surface and its maintenance at a level above that of the felled trees stumps till the end of the vegetation period following that of the iced stratum freezing. Then the thermal insulation is removed and complete melting of the iced stratum is provided for. After the iced stratum melting one performs pre-planting preparation of soil and economically valuable forestry crops planting. ^ EFFECT: high quality suppression of undesired vegetation. ^ 1 tbl |
