NOVELTY - A degrading floating seedling plate comprises 60-70 pts. wt. main material, 0.7-1 pt. wt. straw leavening agent, 10-20 pts. wt. modified starch, 6-8 pts. wt. adhesive, 0.5-0.8 pt. wt. release agent, 3-5 pts. wt. nutrient agent, 0.1-0.3 pt. wt. fertilizer, 0.8-1.2 pts. wt. antibacterial agent and 3-5 pts. wt. waterproof film. The main material is cured tobacco, wheat, corn or soybean straw. The straw leavening agent is white rot fungi, Bacillus, microzyme and Trichoderma reesei.    USE - Degrading floating seedling plate.    ADVANTAGE - The plate has simple proportion, convenient manufacture and good disease resistance ability, and effectively solves tobacco straw waste accumulation and pollution.    DETAILED DESCRIPTION - A degrading floating seedling plate comprises 60-70 pts. wt. main material, 0.7-1 pt. wt. straw leavening agent, 10-20 pts. wt. modified starch, 6-8 pts. wt. adhesive, 0.5-0.8 pt. wt. release agent, 3-5 pts. wt. nutrient agent, 0.1-0.3 pt. wt. fertilizer, 0.8-1.2 pts. wt. antibacterial agent and 3-5 pts. wt. waterproof film. The main material is cured tobacco, wheat, corn or soybean straw. The straw leavening agent is white rot fungi, Bacillus, microzyme and Trichoderma reesei. The adhesive is polyethylene alcohol sizing agent, carboxymethyl cellulose sizing agent or polyvinylpyrrolidone sizing agent. The release agent is paraffin, talc, mica and white clay. The nutrition agent is mixture of potassium dihydrogen phosphate, potassium nitrate, potassium sulfate and ammonium molybdate. The fertilizer is boric fertilizer, molybdenum fertilizer, manganese fertilizer, iron fertilizer and zinc fertilizer. The antibacterial agent is carbendazim, salicylanilide, water, lignin, cinnamic aldehyde, diatomite and kaolin. The waterproof film is polyvinyl alcohol, polyacrylamide or methyl acrylate, pentanenitrile dialdehyde, borax, formaldehyde, aluminum sulfate or glycerin. An INDEPENDENT CLAIM is included for manufacture of degrading floating seedling plate comprising putting straw into pulverizer, crushing into 2-3 cm, regulating water content to 60%, and adding straw fermentation microbial inoculum, fermenting for 3-5 days, adding modified starch, fertilizer and antibacterial agent, mix stirring, adding adhesive and release agent, stir mixing uniformly to prepare raw material premixing liquid, placing into mold, forming into square or round at 100-130 degrees C at bottom reserved diameter of 1-2 mm, and coating.
