The pull rope 12 limits the two sides of the membrane assembly 11 to prevent the membrane assembly 11 from being over-extruded and then forming a flat surface in the soil, and to a certain extent ensures the looseness of the soil to prevent the soil from being too compacted and affecting the breathing of plants. The top middle side of the membrane assembly 11 is connected to the membrane strip structure 2, and the first anchor ring 13 and the second anchor ring 14 are each provided with no less than three, and the first anchor ring 13 and the second anchor ring 14 are located in the middle of the membrane assembly 11 and are symmetrically distributed on the left and right. The anchors are inserted and positioned in the soil through the anchor rings on both sides to ensure the stability of the overall membrane structure after installation.

[0024] Among them, the membrane body assembly 11 includes a waterproof layer 111, an intermediate layer 112, a microporous membrane layer 113 and a hygroscopic layer 114 arranged in sequence from top to bottom. The microporous membrane layer 113 can allow water vapor to pass through, but prevents the penetration of liquid water, thereby enhancing the air permeability and moisture retention capacity of the soil. The top middle side of the waterproof layer 111 is connected to the membrane strip structure 2, and the left and right sides of the inside of the hygroscopic layer 114 are connected to the pull rope 12 to limit the position on both sides by the pull rope 12.
