NOVELTY - Fertilizer comprises solid fertilizer and liquid fertilizer. The solid fertilizer comprises straw powder, peanut shell, glucose, nucleotide, sulfuric acid, phosphoric acid, zinc sulfate, ferric sulfate, magnesium sulfate, copper sulfate, borax and manganese sulfate. The liquid fertilizer comprises glucose, nucleotide, sulfuric acid, phosphoric acid, zinc sulfate, ferric sulfate, magnesium sulfate, copper sulfate, borax, manganese sulfate and ammonium sulfate.    USE - The fertilizer is useful for promoting plant growth and protecting soil (claimed), preventing soil hardening, providing plant nutrition, improving saline alkali soil, quality of crop and disease resistant in crop.    DETAILED DESCRIPTION - Fertilizer comprises solid fertilizer and liquid fertilizer. The solid fertilizer comprises 10-20 wt.% straw powder, 20-30 wt.% peanut shell, 20-30 wt.% glucose, 10-20 wt.% nucleotide, 2-10 wt.% sulfuric acid, 1-5 wt.% phosphoric acid, 2-4 wt.% zinc sulfate, 2-4 wt.% ferric sulfate, 1-2 wt.% magnesium sulfate, 0.5-1 wt.% copper sulfate, 0.5-2 wt.% borax and 1-2 wt.% manganese sulfate. The solid fertilizer is prepared by adding sulfuric acid and phosphoric acid to straw powder and peanut shell, and reacting at 40-60 degrees C for 2-5 hours, then adding glucose, nucleotide, zinc sulfate, ferric sulfate, magnesium sulfate, copper sulfate, borax and manganese sulfate, and continuously reacting for 8-10 hours to obtain the solid fertilizer. The liquid fertilizer comprises 30-50 wt.% glucose, 20-40 wt.% nucleotide, 1-7 wt.% sulfuric acid, 0.5-3 wt.% phosphoric acid, 2-20.5 wt.% zinc sulfate, 3-12 wt.% ferric sulfate, 2-8 wt.% magnesium sulfate, 0.5-1 wt.% copper sulfate, 1-3 wt.% borax, 1.5-4 wt.% manganese sulfate and 0.5-1 wt.% ammonium sulfate. The liquid fertilizer is prepared by adding sulfuric acid and phosphoric acid to glucose and nucleotide, and reacting at 40-60 degrees C for 2-5 hours, and then adding zinc sulfate, ferric sulfate, magnesium sulfate, copper sulfate, borax, manganese sulfate and ammonium sulfate, and continuously reacting for 8-20 hours to obtain the liquid fertilizer. The nucleotide is chosen from adenosine triphosphate, uridine-5'-triphosphate, cytidine triphosphate, and guanosine triphosphate.
