[0002] At present, in the control of desertification, grid sand barriers, sandbag sand barriers, and straw construction grass grid sand barriers have been widely used to fix the mobile desert, and then plant sandy plants on the fixed desert. The transportation cost of the grid straw is very high, and the construction cost is also high, and the straw grass grid will lose its sand-fixing function due to corrosion and weathering in three years, so that the planted plants will face the situation of being eroded by wind and sand again; the grid grid and sandbag sand The cost per unit area of the barrier is much higher than that of the grass square sand barrier, which is an economic burden that cannot be borne by large-scale sand control.

Embodiment Construction
[0018] According to the present invention, the net material for making V-shaped sand-fixing net sand ridge is an anti-aging plastic net with a width between 30cm and 40cm and a porosity between 15% and 25%. The film 7 between 10cm and 20cm is placed into a U-shaped sand-fixing net with a U-shaped cross section, and is cut section by section into a U-shaped sand-fixing net with a length between 60cm and 100cm.
[0019] A sand-fixing net for construction of a V-shaped sand-fixing net in the present invention is a U-shaped sand-fixing net with a length between 60cm and 100cm, and a gap 4 is cut from the center point to a net edge in a vertical direction, and folded into a V-shape when viewed from above. , the cross-section is U-shaped V-shaped sand-fixing net 1, the opening side of the gap of the V-shaped sand-fixing net is the outside 2 of the V-shaped sand-fixing net, and the complete side is the inside 3 of the V-shaped sand-fixing net.

The invention relates to the technical field of sand controlling engineering, in particular to a dot type sand stabilizing construction method for planting plants by V-shaped sand stabilizing net sand ridges. The invention aims to solve the technical problem and provides the technical task of overcoming the defects of prior art. U-shaped sand stabilizing net sand ridges are constructed one by one into dot type sections to be sparsely distributed on desert, the V-shaped sand stabilizing net sand ridges are presented, the outer sides of the V-shaped sand stabilizing net sand ridges are arched toward a main wind direction, the sections of V-shaped sand stabilizing nets filled with sand are U-shaped, two to four psammophytes are planted in pits dug in the inner side of each V-shaped sand stabilizing net sand ridge, or seeds of the psammophytes can be dibble-seeded on the inner side of each V-shaped sand stabilizing net sand ridge, therefore, the aim of greatly reducing a sand controlling cost is achieved.
Description
technical field [0001] The invention relates to the technical field of sand control engineering, in particular to a construction method for point-type sand-fixing and planting plants on sand ridges with V-shaped sand-fixing nets. Background technique [0002] At present, in the control of desertification, grid sand barriers, sandbag sand barriers, and straw construction grass grid sand barriers have been widely used to fix the mobile desert, and then plant sand plants on the fixed desert. The transportation cost of the grid straw is very high, and the construction cost is also high, and the straw grass grid will lose its sand-fixing function due to corrosion and weathering in three years, so that the planted plants will face the situation of being eroded by wind and sand again; the grid grid and sandbag sand The cost per unit area of the barrier is much higher than that of the grass grid sand barrier, which is an unbearable economic burden for large-scale sand control.
