Embodiment 1

[0068] Embodiment one: comprise the following steps:

[0069] a. Prepare modified sand body:

[0070] a1 Polyvinyl alcohol is selected as the substance soluble in water;

[0071] Stir polyvinyl alcohol and water according to the weight ratio of 5:100 to form a solution;

[0072] a2 Mix 200kg of solution formed by dissolving polyvinyl alcohol in water, 1000kg of sand body and appropriate amount of corn seeds and stir evenly to form a modified sand body; the weight ratio of polyvinyl alcohol to sand body in the modified sand body is 1:105.0 ;

[0073] b Spread the modified sand body containing corn seeds on the simulated Gobi surface with a certain area using gravel and saline sand body (the soil content is more than that of ordinary sand body), the paving thickness is about 10cm, and the water content of the modified sand body It is well preserved. Under the spring climate conditions in Chongqing, the evaporation is small. The appearance of the modified sand body is similar...

Embodiment 2

[0076] Embodiment two: comprise the following steps:

[0077] a. Prepare modified sand body:

[0078] a1 The substance that can dissolve in water is selected from hydroxypropyl methylcellulose;

[0079] Stir hydroxypropyl methylcellulose and water according to the weight ratio of 0.2:100 to form a solution;

[0080] a2 Mix 100kg of the solution formed by hydroxypropyl methylcellulose, 1130kg of sand body and appropriate amount of grass seeds and stir evenly. The weight ratio of hydroxypropyl methylcellulose in the modified sand body to the sand body is 1:3779;

[0081] b Spread the modified sand body containing grass seeds on the simulated Gobi surface with a certain area using gravel and saline sand body (the soil content is more than that of ordinary sand body), the thickness of the paving is about 5cm, and the water content of the modified sand body It is well preserved. Under the spring climate conditions in Chongqing, the evaporation is small, and the appearance of the...

Embodiment 3

[0084] Embodiment three: comprise the following steps:

[0085] a. Prepare modified sand body:

[0086] a1 The water-soluble material is sodium carboxymethyl cellulose;

[0087] Stir carboxymethylcellulose sodium and water according to the weight ratio of 1:100 to form a solution;

[0088] a2 Mix 210kg of the solution formed by sodium carboxymethyl cellulose, 1000 kg of sand body and appropriate amount of cabbage seeds and stir evenly. The weight ratio of sodium carboxymethyl cellulose in the modified sand body to the sand body is 1:481.0;

[0089] b. Pave the modified sand body containing cabbage seeds on a certain area of ​​gravel and saline sand body (the soil content is more than the general sand body) to simulate the Gobi surface. The thickness of the paving is about 15cm. Good, under the spring climate conditions in Chongqing, the evaporation is small, the appearance of the modified sand body is similar to that of soil, and the amount of rapeseed added is the amount ...

Abstract

The invention discloses a method for governing gobi by utilizing vegetal modified sand. The vegetal modified sand is paved on the surface of gobi to be governed, and is formed by dissolving a water-soluble solid organic matter in water to form a cohesive and adhesive solution, and mixing the cohesive and adhesive solution with plant seeds and sand; after moisture evaporates, the water-soluble solid organic matter can bond sand, and can be dissolved in water again after meeting water to form the cohesive and adhesive solution to bond sand. According to the invention, common sand can serve as soil; the interaction among sand grains is changed fundamentally; a particle pore structure with binding force (sticking force) is formed; materials cannot run off easily due to the cohesive and adhesive properties; the vegetal modified sand can be as stable as soil, and can store water and nutrients as soil; plants can grow directly after the vegetal modified sand is mixed with the plant seeds. Therefore, the method provides a solid condition for tree growth, and is an ideal gobi governing measure.

Description

technical field [0001] The invention relates to the field of utilization of sand resources and the control of Gobi and Gobi, in particular to a method for treating Gobi by using modified sand with soil properties. Background technique [0002] Gobi is a type of desert, which is a desert terrain covered with coarse sand and gravel on a hard soil layer. The ground is mainly composed of gravel, that is, a desert with undulating and gentle terrain covered with large gravels. The fine sand on the Gobi ground has been blown away by the wind, leaving gravel covered, so there is a difference between a gravel desert and a stony desert. This area is full of sand and rocks, with little water on the ground and few vegetation. [0003] China's Gobi is widely distributed in the vast desert and semi-desert flat land to the northwest of the Wendul Temple-Bailing Temple-Otuoke Banner-Yanchi line, with a total area of ​​about 455,000 square kilometers. The vast Gobi Desert is covered with c...
