Problems solved by technology

The existing method of desert control mainly adopts the method of building windbreaks, but this method requires a lot of investment, slow results, long cycle, difficult follow-up management, and cannot directly prevent desert water from evaporating and losing, and has little effect; people also proposed to use spray film, Treatment methods such as liquid mulch and spraying nutrient solidified water, but the above methods can only work in a short period of time, and cannot provide a suitable growth environment for plants for a long time
In short, none of the existing desert control methods can comprehensively control the desert from the three aspects of sand fixation, water conservation and greening for a long time.

Embodiment approach 1

[0026] figure 1 , the embodiment shown in Fig. 2 comprises the following steps:

[0027] a. Lay artificial turf 1 with a width of about 12 meters on the surface of the desert;

[0028] b. Cut out several linear incisions 11 on the artificial turf, use the umbrella-shaped nails 3 to pass through the linear incisions 11 of the artificial turf and drive into the sandy soil layer 4, so that the heads of the umbrella-shaped nails 3 are pressed on the horizontal bead 7, horizontally The long direction of the bead 7 is perpendicular to the direction of the linear incision 11, and the artificial turf is compressed and fixed;

[0029] c. Use the drilling machine to drill the underground soil layer of the desert to measure the water content of the underground soil layer in the desert;

[0030] d. Cut out a number of circular holes with a diameter of about 0.6 meters on the artificial turf to form a circular planting hole 2. The density of the planting holes 2 is determined according t...

Embodiment approach 2

[0038] A second embodiment of the present invention includes the following steps:

[0039] a. Lay artificial turf 1 with a width of about 9 meters on the desert surface;

[0040] b. Use the drilling machine to drill the underground soil layer of the desert to measure the water content of the underground soil layer in the desert;

[0041] c. Use the locating nail 3 with the hollow hole up and down to pass through the artificial turf and drive into the sandy soil layer 4. After the locating nail 3 is driven into the sandy soil layer, remove the sandy soil in the hollow hole and inject fluid foam plastic 31 into the hollow hole. The foam plastic 31 passes through the hollow hole and reaches the sandy soil layer at the bottom of the positioning nail, and spreads and expands to the surroundings, so that after the foam plastic solidifies, an enlarged root is formed at the bottom of the positioning nail. tight, fixed;

[0042] d. Cut out several square holes of 0.4m x 0.4m on the a...

Abstract

The comprehensive desert tackling method includes the steps of spreading artificial lawn over desert; utilizing positioning nails to fix the artificial lawn; cutting planting hole in the artificial lawn; filling soil in the planting hole and planting; and spreading coarse sand on the artificial lawn. The said method can utilize the precious underground water resource in desert and tackles desert directly from fixing sand, maintaining water and greening. The present invention may be used in both tackling desert and preventing soil desertification and has the advantages of fast effect and short period.

Description

technical field [0001] The invention relates to a method for controlling deserts. Background technique [0002] In the northwestern provinces of our country, there are large deserts, and about 2,000 square kilometers are newly added every year. The existing method of desert control mainly adopts the method of building windbreaks, but this method requires a lot of investment, slow results, long cycle, difficult follow-up management, and cannot directly prevent desert water from evaporating and losing, and has little effect; people also proposed to use spray film, Treatment methods such as liquid mulch and spraying nutrient solidified water, but the above methods can only work in a short period of time, and cannot provide a suitable growth environment for plants for a long time. In short, none of the existing desert control methods can comprehensively control the desert from the three aspects of sand fixation, water conservation and greening for a long time.
