Abstract

A mechanical reclamation of desert method is placing grass curtain on the sand, then connect then to be one by the linking string to fix sand, spray mud on them by patching machine to reach their saturated humidity and form a soil layer on which placing grass seed layer whose density can reach the level of linking the root system for fixing sand, then spray much by patching machine to form the soil lover layer assuring the seed growing, the grass curtain fix sand before decay and supply fertilizer after decay, can keep water and the soil layer can also do. The beneficial effect is that it has sovled three problems existing in reclamation of desert, which is fixing sand, keeping water and enough fertilizer, realized mechanical work, decreased labor density and increased work efficiency.

Description

The desert is administered in mechanization

Affiliated technical field

The invention belongs to the agricultural field, environmental improvement.

Background technology

The more effective desertification control method that present China husky district masses create is filling in into the grid of certain length and width to fix the sand on the sand bed surface with wheat straw, plant grass in grid, plant tree, this method is effective, but handwork, labour intensity is big, efficient is low, for large-area control of desert incompatibility.Though the aircraft seeding grass-seed is arranged, the method for the seeds of trees is not that any area can be used, and more is not that the ordinary people can use.Recent years, country came into effect the western strategy of exploitation, and project of South-to-North water diversion also comes into effect simultaneously, and this has brought opportunity for western large tracts of land control of desert.But the mechanized method that does not adapt to the large tracts of land control of desert so far.

Summary of the invention

In order to overcome existing desertification control method handwork, big, the inefficient deficiency of labour intensity, invention has designed the method that the desert is administered in mechanization.The invention provides a kind of mechanization and administer the method in desert.

The technical solution adopted for the present invention to solve the technical problems is, wheat straw, straw or weeds break into straw screen or mat with straw curtain machine, this straw screen or mat is laid in the sand bed surface, use cable connections between straw screen or mat, large-area straw screen or mat is connected as a single entity to fix the sand and to resist high wind, be used for stirring the yellow mud that forms with a kind of mine to loess and water that the pulp shooting machine that stone head periphery spraying cement mortar is finished with machine with the stirring and the spraying of consolidated rock sprays by a certain percentage to the straw screen or mat surface, make reach capacity humidity and form the alluvial loess bottom of 1-2 cm thick of straw screen or mat, can be for the herbage grass-seed that utilizes on this alluvial loess bottom with mechanical spraying, its density should reach the grass root system form the back root system interlink to fix the sand, spray yellow mud once more and form alluvial loess cap rock on this grass-seed layer, this layer thickness is as the criterion to guarantee that grass-seed can break ground to germinate smoothly.After the grass-seed germination is taken root, its root system sees through the straw screen or mat slit downwards from the alluvial loess formation and stretches into the sand bed, add that alluvial loess bottom has part loess to infiltrate the straw screen or mat slit when forming, this just makes grass, alluvial loess formation, straw screen or mat and sand bed become one, even the arid time is longer, the alluvial loess formation is dry and cracked, and loess formation is also unlikely is blown away by high wind for grass and alluvial, straw screen or mat plays sand fixation before rotting on the other hand, then provides humic fertilizer for herbage growth after rotting.Deposit simultaneously loess formation and straw screen or mat can keep moisture, and the less Atmospheric precipitation of desert area is fully used, for herbage growth.The essence of this method is exactly the loess formation and the sod that can keep moisture to fix the sand for herbage growth in sand bed surface formation artificially with the method for mechanical execution.

The invention has the beneficial effects as follows, realized the mechanized of control of desert work, reduced labour intensity, improved operating efficiency; Three difficult problems in the sand control work have been solved simultaneously: fix the sand to lack the required fertility problem of plant growing in problem, maintenance moisture problem and the desert.

Description of drawings

The present invention is further described below in conjunction with accompanying drawing.

Accompanying drawing is a sectional drawing of the present invention

In the drawings, connection rope 2, alluvial loess bottom 3, herbage grass-seed layer 4, alluvial loess cap rock 5 between straw screen or mat 1, straw screen or mat.

The specific embodiment

In the drawings, straw screen or mat 1 is laid in the sand bed surface and with connection rope between straw screen or mat 2 large-area straw screen or mat is connected as a single entity to fix the sand, on this straw screen or mat 1, spray yellow mud and form certain thickness alluvial loess bottom 3 with pulp shooting machine, reaching the herbage grass-seed layer 4 that can interlink after the root system generation with machinery spraying density on this alluvial loess bottom 3, on this herbage grass-seed layer 4, spray yellow mud with pulp shooting machine again and form the alluvial loess cap rock 5 that the grass-seed that can guarantee in the grass-seed layer 4 is broken ground smoothly and germinates, more than reached mechanization and administered the desert.

Claims

1, the method in desert is administered in a kind of mechanization, lays straw screen or mat (1) on the sand bed surface, and the straw screen or mat (1) that large tracts of land is laid with connection rope between straw screen or mat (2) interlinks and becomes one to fix the sand; Going up the loess and the water that spray by a certain percentage with pulp shooting machine at this straw screen or mat (1) stirs the yellow mud that forms and forms certain thickness alluvial loess bottom (3); Go up spraying density at this alluvial loess bottom (3) and reach the herbage grass-seed layer (4) that interlinks after root system generates; On this herbage grass-seed layer (4), spray yellow mud with pulp shooting machine once more and form the alluvial loess cap rock (5) that the grass-seed that can guarantee in the herbage grass-seed layer (4) is broken ground smoothly and germinates; It is characterized in that: the straw screen or mat (1) that large tracts of land is laid in the sand bed surface interlinks with connection rope between straw screen or mat (2) and becomes one to fix the sand; Going up the loess and the water that spray by a certain percentage with pulp shooting machine at this straw screen or mat (1) stirs the yellow mud that forms and forms certain thickness alluvial loess bottom (3); Go up spraying density at this alluvial loess bottom (3) and reach the herbage grass-seed layer (4) that interlinks after root system generates; The loess and the water that spray by a certain percentage with pulp shooting machine on this herbage grass-seed layer (4) stir the yellow mud that forms and form break ground the smoothly alluvial loess cap rock (5) that germinates of the grass-seed that can guarantee in the herbage grass-seed layer (4) and reaches mechanization and administer the desert again.
