The environment-friendly biodegradable plant propagation multi-pot manufacturing methods and the products using starch and rice byproducts

PURPOSE: A biodegradable plant propagation multi-pot is provided to have moderate strength for plant propagation, and to improve sterilization ability, deodorant ability and heterogeneity, and to be naturally degradable in soil. CONSTITUTION: An environment-friendly composition for plant propagation comprises 30-60 weight% of rice chaff, 5-15 weight% of rice bran, 5-15 weight% of starch, 5-10 weight% of urea, 1-10 weight% of titanium powder, and 20-30 weight% of water. A manufacturing method thereof comprises: a step of crushing the rice chaff and the rice bran by using a pulverizer; a step of forming a composition for plant propagation by using the crushed rice chaff and the rice bran; a step of mixing the composition for plant propagation for 10-20 minutes; and a step of molding the composition by heating and pressurizing.
