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 living sand barriers of wheat in mobile dunes in the specific embodiment of the present invention. Such as 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 wheat seeds evenly on the wet sand layer.

[0035] Step 103, covering sand while sowing.

[0036] Step 104, the wheat germinates and emerges 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 greater than 10 cm. It is firmer...

Abstract

The invention discloses a method for arranging a movable wheat sand-protecting barrier on a moving dune. The method for arranging the movable wheat sand-protecting barrier on the moving dune comprises the steps that a ditch is formed in the moving dune in rainy seasons, wherein the ditch is deep enough to reach the wet sand layer; wheat seeds are evenly sown on the wet sand layer; the wheat seeds are covered with sand; the movable wheat sand-protecting barrier is formed after wheat grows. By the adoption of the method for arranging the movable wheat sand-protecting barrier on the moving dune, the sand stabilizing function can be achieved through the movable sand-protecting barrier, environmental friendliness and economical efficiency are achieved, the method is simple, the survival rate is high, and the storage life is long.

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 wheat 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 af...
