Background technology

Be that the area that the sandyization desert of sign distributes is about 6,000,000 sq-kms with the sand dune fluctuating on the earth, the sand dune area of China is 83.1 ten thousand sq-kms, the ground area that wherein desertifies is 20.1 ten thousand sq-kms, account for 24.2% of national sand dune area, the problems that cause because of the desertization problem are having a strong impact on the land resources safety problem in the China and even the world, also affect the problem of environment for human survival.Sandstorm, environmental problems such as global temperature rising have had a strong impact on the human beings'health life, and bring huge disaster to human economic society.

For drawing out of effective this phenomenon of containment, give the human good living environment of building, the Party and the people are handed down from age to age, and all will drop into huge manpower and financial resources every year, mobilizes the husky district masses to carry out sand control afforestation environment.At present, fixedly sand drift, the basic measures of stopping sand drift and preventing desertization are to adopt biological sand control, mechanical sand control and chemical sand-fixing technology both at home and abroad.

Biological sand control: though can manage protection and utilization rationally to natural vegetation; and artificial planting Qiao, filling, grass and plants such as mosses, algae; consolidate and enlarge vegetation coverage, thereby reach the control hazards of sand storms, improve the ecological environment, the ecosystem that recovers and set up rationally, continue.But this desertification control method transports, water consumption is big, invests wood high.

Mechanical sand control: be to adopt faggot, branch, wood lath, plastic wire, clay, gravel material material to be arranged on the sand ground face,, change the long-pending rule of erosion, reach and check winds and fix drifting sand, make protection object exempt from sand damage with control or promotion dust storm moving situation.Adopt this method to administer desertization, too big because of dropping into, be used for patch improvement so can only adapt to.

Chemical sand-fixing: be the macromolecular compound that utilizes natural or synthetic; be sprayed onto on the sand ground face through being processed into chemical substance with certain cementing properties; infiltrate the sand bed gap; one deck containment vessel will be formed after the grains of sand gluing; separate the direct effect of air-flow, reach tackling quicksand and prevent the purpose of eroding loose Shamian Island.Adopt this method, move though can control dust storm, this method can only be as the complementary and excessive property measure of controlling sediment by plant.

Summary of the invention:

The objective of the invention is defective, a kind of new method of quick improvement desertification is provided at above-mentioned existence.To achieve these goals, the main technical schemes that the present invention solves, at first with hedysarum scoparium, caragana microphylla, step on youth, prairie milk vetch four plant species grass seeds as basic species, in 1: 1: 1: the mixing of 1 ratio; Select sand, loess, nutrition soil as mixture again, and, be encased in then in the little paper bag (3) according to 1: 4 ratio mixed preparing; With straws such as straw, it is the 3-5cm straw rope that the production and processing of process special mechanical equipment becomes diameter, and according to the requirement of spacing in the rows 50cm, to the paper bag of plant seed and nutrition earth mixtures be housed, utilize special-purpose machinery to squeeze in the Manufactured straw rope (1) again, straw rope directly is routed on the surface, sand dune that needs to administer, every then interval 5-6 rice presses one to mill sand (2), promptly finish construction operation, plant species in the straw rope relies on natural precipitation, can root, thereby realize quick fixed dune, the function of restore vegetation.

The present invention has the following advantages through sand control practice and continuous exploration for many years:

The one, utilize batch production to produce that straw rope can solve because the restriction of natural conditions such as weather, traffic, region, places of origin of raw materials processing nearby, the strange land construction, be through with continue to use always manually set up the primitive technology that blocks operation.

The 2nd, the efficiency of construction height, per hour working area can reach 3000 square metres, with traditional manually setting up block operation per hour 200 square metres improve 15 times of effects, saved great amount of manpower.

The 3rd, the raw material of straw rope carrier is a straw, is 2.5kg/10m with grass amount, blocks and economizes on grass 75% than manually setting up grid type.

The 4th, round forms the roping easy to store, easy of product straw rope, and each handcar can transport 1600kg at every turn, and loose and draw straw only for 250kg, be more than 6 times of original freight volume, be applicable to large tracts of land length of run control of desert.

The 5th, need not to irrigate, need not fertilising, straw rope has water retention, utilizes the natural precipitation condition, for plant seed provides growth moisture, treats that can be plant again after straw rope is degenerated naturally provides nutrient.

The 6th, because of executing kind in ground, can select to be fit to local growing plants seed and advance sowing in conjunction with geographical environment.

The 7th, be applicable to the improvement of desertification land, the quick revegetation behind the vegetation deterioration that highway, railway, construction etc. cause has overcome the many drawbacks with artificial sand control, it is difficult to have solved the transportation of sand control raw material, complex procedures, problems such as the plague of rats are the effective ways that quickly fixating sand is administered.

The 8th, both make full use of rice straw and burned the problem of environmental pollution that brings, solved the problem that is difficult to control desertification in the world again.
