Abstract

This invention publicized one kind to use the straw to treat guards against the sand to control the sands, this method was on the desert or the sand land, used the straw to install Sha Duidie the rice straw bag worked as the sand wall, constructed the rice straw bag check and the rice straw bag covers Sha Ti the method, was Sha Ti is not swayed under the wind function with the migration, simultaneously also had good guarantees the water function, created for the cultivated plant has survived and the growth essential condition, could not cause any pollution to the soil, conformed to the environmental protection requirement. This invention has good guards against Sha Gusha the effect, may prevent the sand storm the occurrence, has avoided the desert or the sand storm to humanity's threat.

Description

The method that the straw bag is defended and controlled sand

Technical field the present invention relates to a kind of method of defending and controlling sand, and is specifically related to a kind of method of utilizing the straw bag to defend and control sand.

The background technology desertification is considered to one of world today's great environmental problem, has caused the extensive concern of international community.At present, China has become and has been subjected to one of the most serious country of desertification harm, and the loss that causes is huge especially.For this reason, all will drop into great amount of manpower and material resources and administer every year, and adopting commonplace method is to break into straw checkerboard barrier with straw, corn stalk and wheat straw etc. on the desert, though this has certain regulation effect, usually falls short of success for lack of final effort because of buried by drift sand; In addition, also have and take machinery to fix the sand to plant after the measure method sand control of sand consolidation with biologic such as trees, herbage, but slow, can not reach the effect of timely improvement because of the speed of growth of plants such as trees, herbage.In general, though these measures have obtained some effects in some areas, desertification, sandstorm still continue the survival and development that the Chinese nation in serious threat.

Summary of the invention is present, and defending and controlling sand and adopting commonplace method is to break into straw checkerboard barrier with straw, corn stalk and wheat straw etc., also has taking machinery to fix the sand to plant after the measure sand consolidation with biologic methods such as trees, herbage.Though these measures have certain sand fixation, take effect slow, the weak effect that have, the need that have often drop into human and material resources reparation, expend a large amount of financial resources.The invention is characterized in: can once reach the purpose of defending and controlling sand, need not often to drop into human and material resources and keep in repair, also have certain water retaining function simultaneously, more help planting plants such as trees, herbage.Implementation of the present invention is: first kind of mode is sand blocking wall made by rice straw bags, promptly on desert or sandy land, with the packed full grains of sand of straw, is stacked as the husky wall of retaining of city wall formula on the spot, is used for stopping wind-force, changes wind direction, prevents that husky body from moving.This mode is specially adapted to the protection to railway, highway, water channel and building etc.The second way is a rice straw bag square grid, is about to the packed full grains of sand of straw, constructs the preventing and fixing sand grid by a certain size on husky body, the feature of this mode is different from existing straw checkerboard barrier, and it can not be blown to four winds, and also is difficult for being buried by drift sand, can keep its steadiness for a long time, need not frequent maintenance.This mode is applicable on comparatively smooth desert of physical features or sandy land and implements.The third mode is that the straw bag covers, and is about to the packed full grains of sand of straw, covers Sha Tishang, prevents that husky body from moving the generation with sandstorm.This mode is applicable to the sand prevention of key area, important historical relic, important building protection, particularly the grassland that the part is wrecked and repair because of the impaired vegetation of constructing and to have quick regulation effect.The straw bag method of defending and controlling sand, the material that is adopted is a straw, straw is a kind of renewable plant, wide material sources, braiding straw bag technique is simple, and general personnel can both process, and cheap.Therefore, utilize the straw bag to defend and control sand, both created condition, also found social connections for making full use of straw for increasing peasant income.Simultaneously, straw can not cause any pollution to soil yet, thereby compliance with environmental protection requirements.Therefore, adopt the straw bag method of defending and controlling sand, will bring huge ecological benefits, economic benefit and social benefit for the mankind.

First kind of mode of the specific embodiment: sand blocking wall made by rice straw bags.With the packed full grains of sand of straw, be stacked as the husky wall of retaining of city wall formula on the spot, keep off height, width and length and the trend of husky wall and determine according to actual landform.The position that keeps off husky wall should be selected in that wind direction edge, moving dunes enliven the area under the desert, the basic and this area's cardinal wind quadrature of trend.The second way: rice straw bag square grid.With the packed full grains of sand of straw, on desert or sandy land, construct sand prevention grid (similar) to existing straw checkerboard barrier according to certain specification, the size of grid, height are determined according to actual landform and wind-force size.The third mode: the straw bag covers.The mobile big area in the desert, with the packed full grains of sand of straw, one bag one bag be tiled on the desert tightly covers husky body, stops husky body to move, and prevents to produce sandstorm because of wind blows away the grains of sand.

Claims (2)

1, a kind of method that adopts the straw bag to defend and control sand, it is characterized in that: on desert or sandy land, adopt the folded sand blocking wall made by rice straw bags of the packed sand drift of straw, construct rice straw bag square grid and straw bag and cover the method for husky body, with present normally used straw, corn stalk and wheat straw etc. break into straw checkerboard barrier or fix the sand after the measure by machinery, adopt the identical point of sand consolidation with biologic methods such as plantation plant to be, can both play the effect of fixing the sand, prevent that husky body from moving, thereby reach the control sandstorm, the generation of radical cure desert and desertification, the threat of avoiding desert and sandstorm that the mankind are caused.

2, the straw bag according to claim 1 method of defending and controlling sand is characterized in that three kinds of different governance models, promptly adopts the packed sand drift of straw to fold sand blocking wall made by rice straw bags, constructs rice straw bag square grid and the straw bag covers three kinds of governance models of husky body.These three kinds of governance models can be given full play to sediment trapping, the husky performance of resistance, the disposable regulation effect that reaches of energy needn't often be changed and repair small investment, labour intensity is little, need not special expertise, can both implement throughout the year, and can not cause any pollution soil, and has good water retention, help planting plants such as trees, herbage, and create good surviving and growth conditions, thereby reach the optimum efficiency of improvement.
