NOVELTY - Producing loess compressed nutritive soil comprises e.g. adding loess nutritional soil material in a stirrer and stirring, adding into compressed tableting machine to obtain loess compressed nutritive soil sheet product, conveying the nutrition soil sheet into a microwave belt type drying-sterilizing machine for low-temperature sterilization and drying, conveying into a heat-insulating sterilizing library, using loess nutritional soil sheet waste heat, continuously sterilizing and drying, cooling and packing nutritional soil sheet, obtaining loess compressed nutritive soil finished product.    USE - The method is useful for producing loess compressed nutritive soil (claimed).    ADVANTAGE - The method avoids the surrounding environment secondary pollution, and is suitable for producing nutritive soil of different formulation. The nutritive soil contains nitrogen, phosphorus, potassium, organic matter and multi-elements required for plant growth, reduces pathogenic bacteria and pest harm for the plant, which is good for normal growth and development of plant and protects ecological environment.    DETAILED DESCRIPTION - Producing loess compressed nutritive soil comprises adding loess nutritional soil material in a stirrer and stirring uniformly, adding into compressed tableting machine to obtain loess compressed nutritive soil sheet product, where the sheet thickness is 5-30 mm, (ii) conveying the nutrition soil sheet into a microwave belt type drying-sterilizing machine for low-temperature sterilization and drying, controlling the temperature at 60-100 degrees C, controlling nutritional soil sheet water content at 30-120 minutes, the water content is less than 15%, and (iii) after sterilizing and drying compressed sheet product, conveying into a heat-insulating sterilizing library, using loess nutritional soil sheet waste heat, continuously sterilizing and drying, cooling and packing nutritional soil sheet, obtaining loess compressed nutritive soil finished product, where the loess compressed nutritional soil component comprises 15-35 wt.% acidified loess, 25-55 wt.% acidified sludge, 2-15 wt.% high-viscosity attapulgite clay, 2-15 wt.% biogas slurry soaked gravel-shaped attapulgite floral ceramic, 2-15 wt.% pulverized peat, 2-15 wt.% biogas slag, 1-10 wt.% crushed plant fiber, 0.5-5 wt.% expanded vermiculite, 0.5-5 wt.% expanded perlite, and 0.1-5 wt.% high water-absorbing resin.
