Buried drip irrigation pipe

A buried drip irrigation pipe comprises a drip irrigation pipe body and water outlets, a plurality of water outlets are formed in the drip irrigation pipe body, a lower film layer is arranged at eachwater outlet, an upper film layer is arranged on the back side of each water outlet, and the upper film layers and the lower film layers are bonded. The inner side of the upper film layer is providedwith an upper non-woven fabric layer, the outer side of the upper film layer is provided with an upper water blocking layer, the inner side of the lower film layer is provided with a lower non-woven fabric layer, the outer side of the lower film layer is provided with a lower water blocking layer, and the area of the upper film layer is smaller than that of the lower film layer. 一种地埋式滴灌管，包括滴灌管与出水口，所述滴灌管上设有数个出水口，所述每个出水口处设有下膜层，出水口的背侧设有上膜层，所述上膜层与下膜层粘合。所述上膜层的内侧为上无纺布层，外侧为上阻水层，所述下膜层的内侧为下无纺布层，外侧为下阻水层，所述上膜层的面积小于下膜层的面积，本实用新型可防止出水口被根系或者泥沙阻塞，并且有利于种子发芽，适用于工业化生产。
