Rat-proof buried drip irrigation pipe and manufacturing method thereof

The invention provides a rat-proof buried drip irrigation pipe. The drip irrigation pipe is made of the following components in parts by mass: 40-60 percent of high density polyethylene, 10-30 percent of low density polyethylene, 10-30 percent of linear low density polyethylene, 1-10 percent of rat-proof master batch and 1-2 percent of multifunctional master batch, wherein the rat-proof master batch is prepared from raw materials comprising ethyl cellulose microencapsulated capsaicine particles and cinnamamide. The invention further provides a manufacturing method of the drip irrigation pipe. Through adoption of a co-extrusion technology, rat-proof components exist in the drip irrigation pipe in the form of a color bar. The drip irrigation pipe has a good rat-proof effect, and acts for a longer time.
