The invention discloses a self-leakage-repairing type high-standard farmland PE pipeline sheath applied to the field of PE pipelines, the self-leakage-repairing type sheath is sleeved at the joint of two PE pipelines, and after water leaks, the self-leakage-repairing type sheath is broken to release a waterproof sealant under the dissolution action of a water-soluble film, so that the leakage part is subjected to self-leakage-repairing, and the self-leakage-repairing type high-standard farmland PE pipeline sheath has the advantages that the self-leakage-repairing type high-standard farmland PE pipeline sheath is convenient to use. Meanwhile, the annular water-soluble belt expands under the water guide effect of the first water guide strip, the waterproof sealant is tightly pressed at the water leakage position through the annular water-soluble belt, and therefore the self-leakage-repairing effect is effectively improved, the annular water-soluble belt tightly presses the watertight ring on the PE pipelines un
