METHOD OF "IDEAL"-PEAT SUBSTRATE PREPARATION Russian patent published in 2005 - IPC

FIELD: peat industry.

SUBSTANCE: the invention is dealt with peat industry, in particular, with production of nutrient mediums on the basis of peat for growing of seedlings of forest cultures and garden species and bushes with the closed root systems and a non-polluting vegetable production in a glass-covered ground. The method of preparation of the peat substrate provides for clearing of the peat raw material from large remains of wood and other impurities, introduction of a bio-activator, commixing, fermentation, gauging, packing. In the capacity of peat raw material a weakly decomposed high sphagnum peat or a mossy waste are used and in the capacity of the bio-activator they use a nutrient yeast or a compost ferment in amount of 0.9-1.1 kg per 1 m³ of peat with a density of 0.02-0.1 g / cm³. Fermentation is conducted at the temperature of 10-36°C and moistures of 50-60 %, and gauging after fermentation - up to the particle size of no more than 24 mm. The method ensures production of a product of a loose fibrous structure with the optimal hygroscopic properties, optimal concentration of the nutrient substances and a low toxicity.

EFFECT: the invention ensures production of a product with a loose fibrous structure, optimal hygroscopic properties, optimal concentration of the nutrient substances and a low toxicity.
