Problems solved by technology

However, due to the difficulty in obtaining materials for traditional sand barriers, there are disadvantages such as high cost and slow construction in laying sand barriers. In addition, traditional sand barriers are perishable and pollute the environment. Moreover, the effect of traditional sand barriers on sand prevention and control is short-lived, and it is difficult to be widely promoted.

preparation example Construction

[0027] The present invention also provides a preparation method for the above-mentioned cow dung sand barrier. The preparation raw materials are mixed and then laid into a complete closed cow dung grid to obtain the cow dung sand barrier; the height of the cow dung sand barrier is 12-15 cm. It is preferably 13-14cm; the single side of the cow dung sand barrier is trapezoidal, and the bottom width is 10-15cm, preferably 11-14cm, more preferably 12-13cm; the top width of the cow dung sand barrier is 8cm. ~ 12 cm, preferably 9 ~ 11 cm, more preferably 10 cm.

[0028] In the present invention, the size of the cow dung sand barrier is preferably 1m×1m.

[0029] The present invention also provides the application of the above-mentioned cow dung sand barrier in desertification prevention and control.

[0030] A method for preventing and controlling desertification by using cow dung sand barriers, comprising the following steps: laying the above cow dung sand barriers; transplanting ...

Embodiment 1

[0041] A cow dung sand barrier, which is composed of the following raw materials: per 1m 3 The cow dung contains 0.5kg of Elymus pratense seeds, 0.5kg of bluegrass seeds, 1kg of ryegrass seeds, 0.5kg of purple fescue seeds, 0.25kg of polyacrylamide and 5kg of water.

[0042] The preparation of the cow dung sand barrier:

[0043] The prepared raw materials are mixed and laid into a complete closed 1m × 1m cow dung grid to obtain the cow dung sand barrier; the height of the cow dung sand barrier is 15cm, and the single side of the cow dung sand barrier is trapezoidal. The bottom width is 12-13cm, and the top width is 9-11cm.

Embodiment 2

[0045] A method for preventing and controlling sand by using cow dung sand barriers, comprising the following steps:

[0046] (1) Sample point layout: The sandy land to be treated (Oula Township, Maqu County, Gannan Tibetan Autonomous Prefecture, Gansu Province) will be uniformly drawn and dotted according to the size of 1m×1m, and the sample point layout task will be completed. Place the cow dung sand barrier prepared by embodiment 1;

[0047] (2) Live planting of shrub plants: Adhere to the principle of multiple plants per hole, dig tree pits on the well-placed points, and plant one-year-old mountain willow, seabuckthorn, white sand Artemisia, and scaly water cypress branches in each hole. For seedlings, there are at least 2 species in each hole, and at least 2 plants of each kind, so as to complete the task of living plant planting.

[0048] When planting, a group of 2 to 3 people is formed, one person supports the seedlings, one person aligns the direction, so that the ve...

Abstract

The invention relates to the technical field of sand prevention and control, in particular to a cow dung sand barrier and a preparation method and application thereof. The cow dung sand barrier is prepared from the following raw materials: 0.5 kg of elymus nutans seeds, 0.5 kg of bluegrass seeds, 1 kg of ryegrass seeds, 0.5 kg of red fescue seeds, 0.25 kg of an adhesive and 5 kg of water in every 1 m<-3 > of cow dung; and the adhesive comprises polyacrylamide, sodium polyacrylate, potassium polyacrylate or ammonium polyacrylate. Waste cow dung in a pasturing area is compounded with grass seeds of different plants and the adhesive, the prepared cow dung sand barrier is convenient in material taking, low in cost and fast in construction, the grass seeds in the sand barrier gradually germinate to form seedlings to form a living sand barrier, the sand prevention and control effect of the cow dung sand barrier is further prolonged and is 3-4 times longer than that of a traditional sand barrier, and the cow dung sand barrier is suitable for wide popularization.

Description

technical field [0001] The invention relates to the technical field of sand prevention and control, in particular to a cow dung sand barrier and its preparation method and application. Background technique [0002] The prevention and control of desertification in alpine regions is an urgent and arduous task. Since the 1950s, the desertification phenomenon of the Qinghai Plateau has been paid attention to, and a series of desertification prevention and control work has been carried out in the Gonghe Basin since the 1960s. With the continuous deepening of sand control work, some effective sand control measures have begun to be formed and gradually popularized and applied in the Qinghai Plateau. [0003] The commonly used sand control measures in alpine regions are mainly to set up traditional sand barriers such as wheat straw grid sand barriers, clay sand barriers and nylon net sand barriers. However, due to the difficulty of obtaining materials, traditional sand barriers hav...
