Document Type and Number:
WIPO Patent Application WO/2011/034262
Kind Code:
A1
Abstract:
According to the present invention, a method for manufacturing a biodegradable agricultural mulching film for directly seeding rice comprises the steps of: (A) manufacturing a mixture of raw materials for the biodegradable agricultural mulching film by mixing a raw material having a powder or pellet form and consisting of aliphatic polyester material having encapsulated calcium carbonate containing stearic acid, and then inputting the manufactured mixture of raw materials for the biodegradable agricultural mulching film through an inputting gate of an extruder; (B) blow-molding the mixture of raw materials for the biodegradable agricultural mulching film discharged from the inputting gate through one ejection hole; (C) longitudinally cutting the resultant blow-molded material and obtaining the biodegradable agricultural mulching film by winding the cut blow-molded material around a paper tube so as to be spread as a film; and (D) forming openings in the obtained biodegradable agricultural mulching film at regular intervals, and then attaching rice seeds around the openings.
