PURPOSE: To easily obtain the blasted material appropriate for fertilizer and a soil conditioner by placing the bark of cryptomeria and cypress or its ligneous part in a closed vessel, blasting the material in saturated steam at high temp. and pressure, adding microbes, nitrogen compds., enzyme, etc., to the blasted material and fermenting the mixture. n CONSTITUTION: The bark of cryptomeria or cypress or its ligneous part alone or their mixture is placed in a closed vessel and blasted in saturated steam at high temp. and pressure. The blasting pressure is appropriately controlled to 20-40kg/cm 2 and the blasting temp. to 200-250°C. The microbes such as filamentous fungi and actinomycetes and nitrogen compds. such as ammonium sulfate, nitrolime and urea are added to the blasted material or an enzyme (e.g. cellulase) is added, and the mixture is fermented. Consequently, since the bark, etc., are blasted by the saturated steam at high temp. and pressure, large amts. of the contained lignin, hemicellulose, etc., are decomposed and made soluble and fluffy, and microbes are propagated. n COPYRIGHT: (C)1990,JPO&Japio |
