NOVELTY - Compound leaf fertilizer comprises 9-18 pts. wt. urea, 18-36 pts. wt. potassium dihydrogen phosphate, 6-12 pts. wt. humate, 16-32 pts. wt. composite fertilizer, 3-10 pts. wt. composite microbes, 150-200 pts. wt. composite amino acid liquid, 5-15 pts. wt. potato extract, 1-2 pts. wt. tartaric acid, 0.2-2 pts. wt. piperonyl butoxide, 0.5-1.5 pts. wt. polyvinyl alcohol, 1-2 pts. wt. ethylene diamine tetraacetic acid, 1-2 pts. wt. polyoxyethylene laurate, 1.5-2.5 pts. wt. methyl jasmonate, 3-5 pts. wt. sandalwood extract and 3-5 pts. wt. root of Chinese Pulsatilla root extract.    USE - Compound leaf fertilizer used for cultivating plant (claimed).    ADVANTAGE - The compound leaf fertilizer prevents physiological disease, increases potato yield and quality, enhances stress resistance and increases immune force and disease resistance capacity, and ensures good absorption by potato plant and high utilization rate.    DETAILED DESCRIPTION - Compound leaf fertilizer comprises 9-18 pts. wt. urea, 18-36 pts. wt. potassium dihydrogen phosphate, 6-12 pts. wt. humate, 16-32 pts. wt. composite fertilizer, 3-10 pts. wt. composite microbes, 150-200 pts. wt. composite amino acid liquid, 5-15 pts. wt. potato extract, 1-2 pts. wt. tartaric acid, 0.2-2 pts. wt. piperonyl butoxide, 0.5-1.5 pts. wt. polyvinyl alcohol, 1-2 pts. wt. ethylene diamine tetraacetic acid, 1-2 pts. wt. polyoxyethylene laurate, 1.5-2.5 pts. wt. methyl jasmonate, 3-5 pts. wt. sandalwood extract, 3-5 pts. wt. root of Chinese Pulsatilla root extract, 3-5 pts. wt. caulis spatholobi root extract, 3-5 pts. wt. soybean root extract, 2-6 pts. wt. chitosan and 500-1000 pts. wt. water. The composite fertilizer comprises magnesium sulfate, ammonium molybdate, boric acid, ferrous sulfate, zinc sulfate, copper sulfate, cobalt sulfate, manganese sulfate, sodium selenite in weight ratio of 10:5:7:15:15:3:2:2:4. The composite microbe comprises rice Aspergillus, microzyme, actinomycetes, lactic acid fungus, photosynthetic bacteria, Bacillus subtilis, nitrogen-fixing bacteria, potassium bacteria and mixed flora of phosphorus bacteria. The composite amino acid liquid is obtained from fresh chicken manure. An INDEPENDENT CLAIM is included for a method for preparing compound leaf fertilizer, which involves:    (A) mixing chicken manure, composite microbes and water;    (B) fermenting obtained mixture at 35-40 degrees C for 6-7 days to obtain chicken manure fermented raw liquid;    (C) mixing chicken manure fermented raw liquid, brown sugar and urea;    (D) keeping obtained mixture in fermentation tank for 4-5 days at 30-35 degrees C to obtain composite amino acid liquid;    (E) obtaining bitter sandalwood extract, caulis spatholobi root extract, soybean root extract and potato extract;    (F) mixing remaining materials with obtained extracts and materials in stirrer;    (G) heating obtained mixtuer at 35-45 degrees C for 1-2 hours; and    (H) filtering stirred materials to obtain product that is filled in bottle.
