Abstract

A method for the production of biomass including: planting rows of poplar saplings or cuttings of the species Populus nigra or Populus tremula in ridges with a density greater than 40,000 units per hectare; cutting the plantation annually at the ridge level for a period of 15 to 20 years, and obtaining in each annual cut poplar stalks having a length less than 7 meters and a diameter less than 6 centimeters, and cutting the poplar stalks transversely into substantially cylindrical blocks of biomass having an adjustable length and a variable diameter, coinciding with the diameter of the poplar stalks in the cutting areas.

Claims (8)

1 . A method for the production of biomass, which comprises:

planting rows of black poplar ( Populus nigra ) or European aspen ( Populus tremula ) cuttings in ridges with a density greater than 40,000 units per hectare,

wherein the cuttings to be planted in the first year have a length of between 20 and 30 centimeters,

cutting the planted rows of black poplar ( Populus nigra ) or European aspen ( Populus tremula ) annually at the ridge level for a period of 15 to 20 years, and obtaining in each annual cut poplar stalks having a length less than 7 meters and a diameter less than 6 centimeters,

cutting the poplar stalks transversely into substantially cylindrical blocks of biomass having a length selected during cutting based on the type of boiler in which the blocks will be used as fuel and a diameter corresponding to the diameter of the poplar stalks in the cutting area,

wherein the ridges have a height between 10 and 15 centimeters and are arranged in pairs, and each pair comprises two ridges separated from each other by a distance between 70 and 80 centimeters, and each pair of ridges is separated from the next adjacent pair of ridges by a distance between 100 and 150 centimeters.

2 . The method according to claim 1 , wherein the poplar cuttings within the same ridge row are separated by a distance between 15 and 25 centimeters.

3 . The method according to claim 1 , which comprises covering the terrain between saplings with a permeable anti-weed sheet or mesh during the first year of cultivation.
