NOVELTY - Liquid fertilizer mulching film comprises vermicompost, coffee beans, soybean meal, traditional Chinese medicinal residues, complex microbial agent, modified starch solution, polyacrylamide and water. The complex microbial agent comprises silicate inoculant, Bacillus subtilis microbial inoculum and photosynthetic bacterium microbial inoculum. The modified starch solution comprises potato starch, calcium acetate, potassium permanganate solution, acrylic acid, sodium hydroxide, N,N-methylene bisacrylamide, ferrous sulfate, zinc sulfate and manganese sulfate.    USE - The liquid fertilizer mulching film is used for planting corn (claimed).    ADVANTAGE - The liquid fertilizer mulching film increases fertilizer use efficiency.    DETAILED DESCRIPTION - Liquid fertilizer mulching film comprises 37-43 pts. wt. vermicompost, 7-10 pts. wt. coffee beans, 26-28 pts. wt. soybean meal, 19-21 pts. wt. traditional Chinese medicinal residues, 3-5 pts. wt. complex microbial agent, 16-20 pts. wt. modified starch solution, 1-2 pts. wt. polyacrylamide and suitable amount of water. The complex microbial agent comprises silicate inoculant, Bacillus subtilis microbial inoculum and photosynthetic bacterium microbial inoculum in ratio of 2:1:1. The modified starch solution comprises 45-55 pts. wt. potato starch, 2-4 pts. wt. calcium acetate, 2-3 pts. wt. potassium permanganate solution, 15-20 pts. wt. acrylic acid, 3-4 pts. wt. sodium hydroxide, 0.1-0.3 pt. wt. N,N-methylene bisacrylamide, 8-10 pts. wt. ferrous sulfate, 6-8 pts. wt. zinc sulfate and 7-9 pts. wt. manganese sulfate. The modified starch solution is prepared by dissolving potato starch in 2 times water, gelatinizing at 70-90 degrees C for 30-60 minutes, adding potassium permanganate solution, stirring for 50-70 minutes, adding acrylic acid, sodium hydroxide and N,N-methylene bisacrylamide, cross-linking for 20-30 minutes, adding calcium acetate, stirring, adding ferrous sulfate, heating to 50-60 degrees C, chelating for 15 minutes, adding zinc sulfate, chelating for 15 minutes, adding manganese sulfate, heating to 60-80 degrees C, and chelating 20-30 minutes to obtain chelated iron, zinc, manganese modified potato starch solution. An INDEPENDENT CLAIM is included for method for producing the liquid fertilizer mulching film.
