NOVELTY - A water-soluble foliar fertilizer comprises sodium fulvate, potassium dihydrogen phosphate, carbamide, ammonium sulfate, waste silk, feather powder, monosodium glutamate leftovers, zinc nitrate, manganese sulfate, magnesium sulfate, sodium sulfate, boric acid, EDTA, kelp dreg, rape seed cake, soybean meal, beer, waste liquid, towel gourd, cortex meliae, tung root, radix sophorae flavescentis, thunder god vine, and daphne.    USE - A water-soluble foliar fertilizer.    ADVANTAGE - The fertilizer reduces disease rate of crop, reduces use of chemical pesticide, promotes fast growth, enhances stress resistance of crops, and improves quality of crops.    DETAILED DESCRIPTION - A water-soluble foliar fertilizer comprises 30-40 pts. wt. sodium fulvate, 40-50 pts. wt. potassium dihydrogen phosphate, 20-30 pts. wt. carbamide, 10-15 pts. wt. ammonium sulfate, 25-35 pts. wt. waste silk, 15-20 pts. wt. feather powder, 5-10 pts. wt. monosodium glutamate leftovers, 2-3 pts. wt. zinc nitrate, 1-2 pts. wt. manganese sulfate, 1-2 pts. wt. magnesium sulfate, 0.5-1.5 pts. wt. sodium sulfate, 1-2 pts. wt. boric acid, 0.5-1 pts. wt. EDTA, 10-15 pts. wt. kelp dreg, 5-10 pts. wt. rape seed cake, 8-12 pts. wt. soybean meal, 5-10 pts. wt. beer, 8-12 pts. wt. waste liquid, 2-3 pts. wt. towel gourd, 1.5-2.5 pts. wt. cortex meliae, 1-2 pts. wt. tung root, 2-3 pts. wt. radix sophorae flavescentis, 1-2 pts. wt. thunder god vine, and 2-3 pts. wt. daphne. An INDEPENDENT CLAIM is included for preparation of water-soluble foliar fertilizer comprising:    (A) mixing uniformly waste silk and feather meal at a ratio of 1:3-5, where the material liquid concentration comprises 15-20% sulfuric acid solution, hydrolyzing for 4-6 hours at 105-115 degrees C, and then modifying using 10-15% sodium hydroxide solution and hydrolysis solution until it is neutral, then adding monosodium glutamate, zinc nitrate, magnesium sulfate, sodium chloride, boric acid and EDTA, heating at 80-90 degrees C, carrying out chelating reaction for 30-40 minutes, concentrating, and freeze-drying to obtain the powder and chelated fertilizer;    (B) taking luffa vine, bark, tung root, radix sophorae flavescentis, thunder god vine and castor girald daphne, mixing uniformly, adding 4-8 times water to boil in low heat to extract for 2 hours, filtering, and concentrating the filtrate;    (C) mixing uniformly the kelp residue, rapeseed cake, soybean meal, beer, and methane waste liquid, filtering, adding water, controlling the amount of water to obtain the fermentation liquid, concentrating to proper amount, freezing and drying to obtain 50-60% powder, stirring uniformly, seal fermenting, controlling temperature at 32-36 degrees C, after 10-15 days fermentation, filtering the fermentation liquid; and    (D) mixing sodium yellow humic acid, monopotassium phosphate, urea, ammonium sulfate and amino acid chelated fertilizer, and packaging to obtain the finished product.
