Embodiment Construction

[0031] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0032] figure 1 It is a flow chart of the setting of live sand barriers of highland barley in mobile dunes in the specific embodiment of the present invention. like figure 1 As shown, the process includes the following steps:

[0033] Step 101, generally in mid-June, during the rainy season, sow the seeds on the mobile sand dunes, and use a special artificial opener to open a ditch with a depth of 4 to 5 cm.

[0034] Step 102, spreading the highland barley seeds evenly on the wet sand layer.

[0035] Step 103, covering sand while sowing.

[0036] Step 104, the highland barley germinates and unearths in one week, and grows 5 to 8 cm high in half a month, which can play the role of sand barrier. It grows 10 to 15 cm high in one month, and reaches a maximum of 20 to 40 cm. The root depth is greate...

Abstract

The invention discloses a method for arranging a highland barley living sand barrier in a moving dune. During the rainy season, the moving dune is ditched, and the depth of ditches reaches the wet sand bed; highland barley seeds are evenly sowed in the wet sand bed; the highland barley seeds are covered with sand; the highland barley living sand barrier is formed after the highland barleys grow up. By the adoption of the technical scheme, the living sand barrier can play the functions of sand stabilization, environment protection and energy conversation and is simple in method, high in survival rate and long in storage life.

Description

technical field [0001] The invention relates to the technical field of windbreak and sand fixation in alpine regions, in particular to a method for setting live barley sand barriers on moving sand dunes. 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 a combination of mechanical and biological measures. The mechanical measures are mainly to set up wheat straw grid sand barriers and clay sand barriers. The biological measures are direct seeding a...
