NOVELTY - Nutritious vegetable special fertilizer and its preparation method are claimed. The vegetable special fertilizer comprises 40-50 pts. wt. castor rod, 10-12 pts. wt. grain amaranth, 20-30 pts. wt. silkworm pupa, 60-70 pts. wt. calcium superphosphate, 30-40 pts. wt. ammonium sulfate, 14-16 pts. wt. potassium silicate, 10-12 pts. wt. coal powder, 7-9 pts. wt. ferrous sulfate, 6-9 pts. wt. potassium sulfate, 4-6 pts. wt. manganese sulfate, 3-4 pts. wt. zinc gluconate, 5-8 pts. wt. soybean oil, 10-15 pts. wt. soil conditioner, and water (remainder).    USE - As nutritious vegetable special fertilizer.    ADVANTAGE - The nutritious vegetable special fertilizer promotes the growth and development of vegetable, improves disease resistance, quality and yield of vegetables, soil structure, water preservation and fertility of soil, and is rich in organic matter, highly safe as it does not cause toxic effects.    DETAILED DESCRIPTION - Nutritious vegetable special fertilizer and its preparation method are claimed. The vegetable special fertilizer comprises 40-50 pts. wt. castor rod, 10-12 pts. wt. grain amaranth, 20-30 pts. wt. silkworm pupa, 60-70 pts. wt. calcium superphosphate, 30-40 pts. wt. ammonium sulfate, 14-16 pts. wt. potassium silicate, 14-18 pts. wt. potassium chloride, 12-15 pts. wt. potassium feldspar powder, 10-12 pts. wt. coal powder, 8-10 pts. wt. fly ash, 4-5 pts. wt. zinc sulfate, 7-9 pts. wt. ferrous sulfate, 6-9 pts. wt. potassium sulfate, 4-6 pts. wt. manganese sulfate, 3-4 pts. wt. zinc gluconate, 5-8 pts. wt. soybean oil, 10-15 pts. wt. soil conditioner, and water (remainder), where the soil conditioner comprises 150-170 pts. wt. attapulgite, 40-45 pts. wt. bamboo charcoal, 5-7 pts. wt. nano jade powder, 1-2 pts. wt. nano-carbon powder, 1-2 pts. wt. ascorbic acid, 4-5 pts. wt. starch, 2-3 pts. wt. polyvinyl alcohol, 4-5 pts. wt. manganese sulfate, 3-4 pts. wt. ammonium citrate, 4-5 pts. wt. soybean oil, 1-2 pts. wt. sodium alginate, 2-3 pts. wt. ammonium persulfate, and 3-4 pts. wt. water. The method involves adding the above-mentioned raw materials except ammonium persulfate to water, mixing, and grinding the mixture into slurry, heating the slurry at 80-90 degrees C, and adding ammonium persulfate, stirring and reacting the mixture for 40-60 minutes, heating and concentrating the reacted mixture to paste, preparing the paste into granule, and drying the obtained product.
