NOVELTY - Producing sepiolite compressed nutritive soil comprises stirring sepiolite comprising e.g. acidified sepiolite, acidified sludge, high-viscosity attapulgite clay, pulverized peat and biogas slag into an input mixer, tableting to obtain gangue compressed nutritive soil sheet substance, conveying into a microwave belt drying sterilization machine, carrying out low temperature sterilization and drying, conveying the sterilized and dried sepiolite nutritive soil sheet into a heat-insulation sterilization reservoir, utilizing the waste heat, sterilizing and drying, cooling and packaging.    USE - The method is useful for producing sepiolite compressed nutritive soil (claimed).    ADVANTAGE - The nutritive soil: contains nitrogen, phosphorus, potassium, organic matter and multiple elements, which can provide nutritional elements required for plant growth; and reduces harm to a plant caused by pathogenic bacteria and pests, thus ensuring normal growth and development of plant and protecting ecological environment.    DETAILED DESCRIPTION - Producing sepiolite compressed nutritive soil comprises stirring sepiolite into an input mixer, allowing to enter into a tableting machine to obtain gangue compressed nutritive soil sheet substance, controlling the thickness of the sepiolite sheet substance to be 5-30 mm, conveying into a microwave belt drying sterilization machine, carrying out low temperature sterilization and drying, controlling the temperature at 60-100 degrees C for 30-120 minutes, and drying until the water content is less than 15%, conveying the sterilized and dried sepiolite nutritive soil sheet into a heat-insulation sterilization reservoir, utilizing the waste heat of sepiolite nutritive soil sheet, continuously sterilizing and drying, cooling and packaging to obtain the finished product. The sepiolite comprises 15-35% acidified sepiolite, 25-55% acidified sludge, 2-15% high-viscosity attapulgite clay, 2-15% biogas impregnated gravel-shaped attapulgite floral ceramic, 2-15% pulverized peat, 2-15% biogas slag, 1-10% crushed plant fiber, 0.5-5% expanded vermiculite, 0.5-5% expanded perlite and 0.1-5% high water-absorbing resin.
