NOVELTY - Humic acid type fluid or solid organic-inorganic compound fertilizer, comprises 5-500 pts. organic fertilizer, filter mud from sugar refinery, alcohol, monosodium glutamate (MSG), yeast, 5-500 pts. inorganic fertilizer, and trace elements.    USE - As humic acid type fluid or solid organic-inorganic compound fertilizer.    ADVANTAGE - The fertilizer improves chlorophyll content in cucumber blade.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) method for preparing the above-mentioned humic acid type fluid or solid organic-inorganic compound fertilizer, which involves (a) adding water in fermentation tank, fermenting the mixture at 50-80 degrees C, adding the fresh filter mud in the fermentation tank and uniformly stirring the mixture, where the filter mud, water and fermentation microbial inoculum are mixed in a weight ratio of 100-200:200-600:0.5-5, (b) filtering the fermented liquid at 50-80 degrees C for 5-10 days and stirring the filtrate, (c) standing the filtrate at normal temperature for 5-10 hours, collecting fermented liquid and removing precipitate from the bottom, (d) concentrating the fermented liquid 60-80 degrees C, collecting the concentrate to a initial weight ratio of 1/6 to 1/15, cooling the concentrate to normal temperature, adjusting pH value of the concentrate to 6-8, filtering the cooled broth, regulating concentrated liquid pH value to 6-8 and inoculating fermentation microbial inoculum chosen from Aspergillus oryzae, A.niger, Bacillus cereus, B.megaterium, Candida, nitrogen fixing Rhizobium and Azospirillum, and (e) adding large number of elements chosen from urea fertilizer, ammonium nitrate, potassium dihydrogen phosphate, superphosphate, potassium chloride, and potassium nitrate, fertilizer elements are chosen from calcium sulfate, magnesium sulfate, magnesium chloride, and their mixtures, trace element fertilizer are chosen from sulfate, manganese sulfate, zinc chloride, copper sulfate, ammonium and sodium, and penetrating agent is chosen from wetting penetrant T, alkyl glycosides, polyoxyethylene trisiloxane, and methyl oleoyl taurate, where the method involves adding 30-80 pts. filter mud fermented residue, 8-20 pts. macronutrients fat, 2-6 pts. fertilizer elements, and 1-5 pts. trace element fertilizer; (2) method for increasing crop blade chlorophyll content, increasing crop root and/or increasing crop yield, involves spraying fertilizer, preferably solid fertilizer to plant at a dose of 40-60 kg time and spraying fluid compound fertilizer at a dose of 3-6 kg after diluting the fertilizer for 15-30 times; and (3) fertilizer for increasing the crop blade chlorophyll content by performing the above-mentioned method.
