The embodiments of the present application provide a method for making continuous micro-irrigation tubing, the continuous micro-irrigation tubing so made, a method for performing irrigation using the said continuous micro-irrigation tubing, and the application of the said continuous micro-irrigation tubing in agricultural irrigation, wherein the method for making continuous micro-irrigation tubing comprises: preconditioning a filler blending the preconditioned filler with high-pressure polyethylene resin at a predefined weight ratio and making said filler and resin into filler pellet making preformed tubing from the filler pellet and threading the preformed tubing into a high-temperature extractor in which continuous extraction is performed to make continuous micro-irrigation tubing. The method enables the making of continuous micro-irrigation tubing containing micro-pores on the tubing wall. After the continuous micro-irrigation tubing is filled with water, water exudes through the micro-pores.
