The planting unit opening includes a middle planting part and a first dividing part, a second dividing part, a third dividing part, and a fourth dividing part located outside the middle planting part;

[0005] The planting unit is provided with a first part, a second part, a third part, and a fourth part. The first dividing part is located between the first part and the second part, the second dividing part is located between the second part and the third part, the third dividing part is located between the third part and the fourth part, and the fourth dividing part is located between the fourth part and the first part.

[0006] Further, the geomembrane includes an upper layer of polyester geotextile and a lower layer of polyethylene film.

[0007] The beneficial effects of the utility model are as follows:

[0008] The desert planting composite geomembrane of the utility model, on the one hand, can prevent the wind from blowing the sand, thus achieving the effect of sand fixation and not generating dust. At the same time, it is beneficial for rainwater to concentrate on the plant roots, and can effectively prevent the evaporation of groundwater. It can gather water vapor under the membrane, increase the water content of the surface layer, and is beneficial for the absorption and growth of plant roots. Description of the Drawings

[0014] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings required for use in the embodiments will be briefly introduced below. Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts.

[0015] The present invention will be described in detail below in conjunction with the drawings and specific implementation manners. The implementation manners cannot be elaborated one by one here, but the implementation manners of the present invention are not limited to the following implementation manners.

[0016] Combined with Figures 1 - 3 As shown, the present invention provides a desert planting composite geomembrane, including a geomembrane 1. The upper layer of the geomembrane 1 is a degradable polyester geotextile, and the lower layer is a degradable polyethylene film. A plurality of planting units 2 for planting plants are arranged at equal intervals on the geomembrane 1.

[0017] According to an embodiment of the present invention, an opening 3 is provided in the middle of the planting unit 2. The opening 3 includes a middle planting part 31 and a first dividing part 32, a second dividing part 33, a third dividing part 34, and a fourth dividing part 35 located outside the middle planting part 31. The planting unit 2 is provided with a first part 21, a second part 22, a third part 23, and a fourth part 24. The first dividing part 32 is located between the first part 21 and the second part 22, the second dividing part 33 is located between the second part 22 and the third part 23, the third dividing part 34 is located between the third part 23 and the fourth part 24, and the fourth dividing part 35 is located between the fourth part 24 and the first part 21.

[0018] The usage method of the desert planting composite geomembrane of the present invention is as follows:

[0019] Lay the desert planting composite geomembrane of the present utility model on the sand dune. Open planting units 2 in the upper planting area of the geomembrane 1. Then, dig out part of the soil on the lower side of the geomembrane 1 at the planting units 2 for plant planting. Then lay the first part 21, the second part 22, the third part 23, and the fourth part 24 at an inclination of 45° into the planting pits, and then use the dug-out soil to bury the first part 21, the second part 22, the third part 23, and the fourth part 24 to a certain extent by burying the outer periphery of the geomembrane 1.
