USE - The organic fertilizer is useful for Gynura divaricata plant.    ADVANTAGE - The organic fertilizer reduces the pollution to soil and water thus ensuring the growth of the plant.    DETAILED DESCRIPTION - Organic fertilizer comprises 5-10 wt.% of urea, 2-5 wt.% of monoammonium phosphate, 4-5 wt.% of potassium carbonate, 4-6 wt.% of monopotassium phosphate, 10-15 wt.% of humic acid, 5-7 wt.% of lignin, 3-5 wt.% of butyl acrylate, 5-10 wt.% of water, 1-5 wt.% of chitosan, 3-7 wt.% of sodium borate, 0.5-1 wt.% of zinc chloride, 0.05-0.3 wt.% of sodium molybdate, 0.05-0.1 wt.% of manganese sulfate, 0.05-0.3 wt.% of sodium dodecyl benzene sulfonate, 0.8-2 wt.% of ferrous sulfate, 0.03-0.8 wt.% of magnesium sulfate, 0.01-0. 05 wt.% of copper sulfate, 0.2-2 wt.% of dimethyl sulfoxide, 2-10 wt.% of plant fiber and livestock excrement as major ingredients, where the plant fiber is crop straw, sedge, corncob or bagasse, and the livestock excrement is pig manure, cow dung, sheep manure or stool of chicken or duck, where the organic fertilizer is prepared by selecting and weighing the ingredients, grinding the plant fiber into powder, mixing the livestock excrements and the plant fiber powder, sending the mixture into a fermentation vat, covering the fermentation vat using a moisturizing and insulating material when temperature of the vat reaches 50-70 degrees C, performing the fermentation process for every 24 hours, and finishing the fermentation process after completing 5-6 times, mixing the fermented product with urea, monoammonium phosphate, potassium carbonate, monopotassium phosphate, nanometer ferrous sulfate, nanocarbon, humic acid, lignin, water, chitosan, sodium borate, zinc chloride, sodium molybdate, manganese sulfate, sodium dodecyl benzene sulfonate, ferrous sulfate, magnesium sulfate, copper sulfate and dimethyl sulfoxide, stirring and dissolving the mixture in water at 100-120 degrees C for 2 hours, finishing a blending process after heating process is completed, and screening the solution with a sieve of 200 meshes to remove residue. An INDEPENDENT CLAIM is included for a method of using organic fertilizer, comprising diluting the fertilizer into water for 100 times and spraying the diluted fertilizer into the soil once in every three days at seedling time, diluting the fertilizer into water for 150 times, spraying the diluted fertilizer into the soil for two times in a week and evenly covering the Gynura divaricata leaves in seedling stage, diluting the fertilizer into 300 times of water, emerging the flower bud using fertilizer to the leaves for two times for two days and splashing the fertilizer onto the leaves of the plants in early phase of flowering, and diluting the fertilizer into 400 times of water, spraying the diluted fertilizer onto the blooming flower, splashing the diluted fertilizer around the plant, and minimizing the contact of the diluted fertilizer with petals.
