The preparation method of functional fertilizer for growing the lawn grass and the functional fertilizer utilizing thereof

摘要

PURPOSE: A functional fertilizer for grass vegetation with plentiful far infrared radiation and alkali materials is provided to improve growth of grass, and prevent soil acidification and water pollution. CONSTITUTION: The functional fertilizer is manufactured by grinding nano-sized discharge water and inorganic composite powder in a ratio of 1:1 for 48hrs by rotation(40-80rpm) to be a mixture(gel type) with colloidal particles (10-100nm), followed by diluting the mixture with water for 1 : 5-20 dilution. The inorganic composite powder is obtained by grinding inorganic composite materials like granites containing more than 25% of K2O, MgO, Na2O and CaO, less than 58% of SiO2 and less than 20% of Fe2O3 and Al2O3, and classifying into 1micrometer(12500mesh) size by vacuum pressure difference. Also, the gel type mixture is continuously discharged, heated to 30-60deg.C, and diluted 10-50times by water for use as functional fertilizer.
