METHOD FOR KEEPING OF PLANTS DURING COLD PERIOD OF YEAR Russian patent published in 2005 - IPC

FIELD: forestry, in particular, keeping of plants with closed root system during cold periods of year, for example, plants grown in containers or seedlings.

SUBSTANCE: method involves placing containers 5 with plants 4 at place 1 above heating main 2; providing covering 4 above containers 5; filling space between covering wall 3 and containers 5 with bulk material 6 with increased moisture capacity (for example, peat or compost); moistening material 6 and mellowing top layer 7 of said material. During heating season, part of heat is transferred from heating main 2 to ground surface. Moistened peat layer 6 has increased moisture capacity to provide for effective heating of containers 5. Mellowed layer 7 eliminates moisture and heat transfer from layer 6. Moisture stock in layer 6 provides optimal soil moisture in containers to be maintained. When necessary, layer 6 is periodically moistened and layer 7 is mellowed. Covering 3 and layers 6 and 7 of peat reduce heat losses from heating main 2 during the entire heating season. Upon completion of cold period, containers 5 with plants 4 are moved to territory to be landscaped.

EFFECT: reliable storage of plants, reduced costs for earth excavation works and heating of storage, provision for keeping soil moisture capacity in containers within optimal range, and reduced heat losses at heating mains.
