TECHNOLOGY FOCUS - POLYMERS - Preferred Material: The paper-making material can be waste paper fibers, biodegradable plant fibers or polymer fibers. The adhesive material is natural amylum gel, carboxymethyl cellulose, glue spray and/or starch.Preferred Component: The dry strength agent is melamine formaldehyde resin, polymeric amine-epichlorohydrin resin, phenoic resin, glyoxalated polyacrylamide resin, polyacrylamide resin, raw starch, modified starch, gelatin or anionic or cationic acidic or neutral dry strength agent. The wet strength agent is melamine formaldehyde resin, polymeric amine epichlorohydrin resin, phenoic resin, glyoxalated polyacrylamide resin or various anionic or cationic acidic or neutral wet strength agent. The chemical agent is ethylene glycol, propylene glycol, butylene glycol, polyethylene glycol, polypropylene glycol, polybutylene glycol, glycerin or 2-octyl glycol.    TECHNOLOGY FOCUS - TEXTILES AND PAPER - Preferred Method: The papermaking material is treated to form a cleaned paper pulp by classifying, pulp-dispersing, coarse pulp-clarifying, fiber-separation, coarse screening, fine pulp-clarifying, fine screening, heat-dispersion, bleaching, pulp-washing or pulp-refining. The Camellia seed cake's powder is added into the cleaned paper pulp at 1% for controlling the propagation of golden apple snails and increasing dispersion level of the fibers. The calcium carbonate is added into the cleaned paper pulp at a usage based on the classification of the papermaking material, sieving ratio of the fibers, desired water-absorbing ability and air permeability of the mulching paper for increasing the physical strength of the mulching paper, encouraging the breed of microorganisms and decrease the pesticide of sodium dodecyl sulfate (SDS) or Camellia seed cake's powder consumption. The fertilizer powder or capsules are coated on the mulching paper to form a slowly released organic or chemical fertilizer coating (3) to provide required nutrition for plants. A fixing layer (5) is attached on the mulching paper by an adhesive material for securing the seeds on the mulching paper. The seeds are treated by a chemical agent cooperating with algin soda acid, gelatin or polyvinyl alcohol for protecting the germination of seeds.Preferred Property: The multi-purpose functional agricultural mulching paper has a neutral pH of 6, basic weight of at least 120-150 g/m2, thickness of 0.2-0.3 mm, water-absorbing ability larger than Cobb, 1 minute, 20 gsm, wet-breaking force in machine direction/cross direction lower than 1.0 kg/m2 after two hours immersion, and air permeability larger than 50 seconds/100 cc.Preferred Component: The multi-purpose functional agricultural mulching paper has light-blocking weed control ability and natural porous carriers for microorganisms to breed so that antagonistic microorganisms for controlling diseases of the plants, pest control agent and bacterial control agent can be coated, sprayed or immersed on the paper.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Component: The weed control agent is various inorganic or organic packing material from black carbon, silicon dioxide or titanium dioxide.    TECHNOLOGY FOCUS - BIOLOGY - Preferred Component: The antagonistic microorganisms for controlling diseases of the plants are rice sheath blight (Rhizoctoria Solani is one of the most important rice diseases) or radish seeding blight antagonistic microorganisms. The antagonistic microorganism, the pest control agent and the bacterium control agent can be coated on the surface of the mulching paper by an adhesive material. The seeds are seeds covered by paper pulp, seeds covered by polymer compound, seeds of cereal, seeds of medicinal herbs, seeds of economical plant, seeds of greensward, seeds of vegetables, seeds of flower, seeds of fruit, seeds of forestry tree or artificial seeds cultivated by embryonic callus or cell organization.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Component: The functional additive is Camellia seed cake's powder, calcium carbonate, dry strength agent, wet strength agent, weed control agent, pest control agent or bacterial control agent. The pest control agent SDS or linear alkyl sulfate, agricultural waste containing saponin and methyl alcohol extracted from Camellia seed cake or tobacco dust powder.
