Abstract
The invention discloses a method for preventing and stabilizing sand, comprising the following steps of: (1) preparing colloid mud: mixing and stirring the colloid mud and water according to the ratio of 1:15 and feeding the mixture into a spray pot; and (2) spraying: spraying the colloid mud on desertified land according to the spray amount of 0.5-1kg/m<2> so that not only the surface of desert can be stabilized, but also and prevent the sand body from flowing, but also prevent sand storm. The invention has the advantages of low cost, convenient operation, quick response, no toxic or side effect, no pollution and no influence on the growth of plants.
Description
Technical field
The present invention relates to a kind of method for preventing and stabilizing sand.
Background technology
/ 4th of a present global land surface is suffered the harm of desertification, has the multiple district of four big sandstorms in the world, and they are respectively: North America, Australia, the Central Asia and the Middle East that comprises middle not sum West Asia.
The desert in North America mainly is distributed in US West and Mexican the north.At the desert arid biogeographic zone of bordering on the desert, sandstorm happens occasionally, even has broken out historical famous black burn on llanura, reason such as that the reason of North America sandstorm mainly is that the soil utilizes is improper, continuous drought.20th century, an especially big sandstorm took place in the '30s US West llanura, was called as black burn, and in the most serious sandstorm, llanura has lost 300,000,000 tons rich soil on this American history.After the great calamity, millions of hectares farmland is discarded, and the hundreds of thousands stream of people is from becoming homeless, and numerous cities and towns become the empty city that is desolate and uninhabited.Many people are forced to the inferior migration of secondary Buddhist nun of markon, have caused the wave of immigration of maximum on the American history.
Australia is an arid country, and 75% of land surface belongs to the arid and semi-arid lands.Australian middle part and the area sandstorm of western seashore are the most frequent, on average have every year five times more than.Because many microclimate dryings, add farming and herd that the covering of upper soll layer shortage vegetation has caused the desertification gradually in soil, in case sweep strong wind, sandstorm will produce.
The desert district at middle part, Asia is also in continuous expansion, and the five Central Asia countries of the former Soviet Union are relatively serious area of desertification, and the gross area has nearly 4,000,000 square kilometres.Because the quick increase of population, the people is the heavy irrigation water, the indiscriminate felling of trees forest, and overgrazed, deterioration of grasslands, desertification is very serious.Central Asia's solonchak area is very vast, reaches 150,000 square kilometres, so caused the mixing of sandstorm and salt dust storm to take place.
The sandstorm of Middle East is mainly in edge area, Sahara south, from the early 1970s to the mid-80, because drought and the locals is excessive herds and open up wasteland year after year, cause deterioration of grasslands, the field is uncultivated, desertification land spreads, the sandstorm aggravation, and locals's living environment sharply worsens.Other area is also brought disaster in frequent sandstorm, and the sand and dust that have are crossed the Atlantic Ocean by the wind band and arrived South America Amazon area, and the sand and dust that also have have been blown to Europe.
China is one of serious country of desertification harm in the world, the control desertification, and the containment hazards of sand storms is built good ecologically, is a long-term and important strategic task.
Desertification is a type of desertification of land, and main reason is climatic factor and human irrational activity in production.Desertification has produced serious harm to human social economy's life.Check winds and fix drifting sand and water resource utilization rationally is 2 key issues of control of desert.
Summary of the invention
The technical issues that need to address of the present invention just are to overcome the defective of prior art, and a kind of method for preventing and stabilizing sand is provided, and its cost is low, are convenient to operation, and instant effect has no side effect, and is pollution-free, do not influence the growth of plant.
For addressing the above problem, the present invention adopts following technical scheme:
A kind of method for preventing and stabilizing sand of the present invention, described method comprises the following steps
1), the preparation of colloid mud: with colloid mud and water is 1: 15 ratio by weight, is mixed into colloidal substance, squeezes in the spray tank;
2), spraying: press 0.5-1kg/m
2Quantity for spray the colloid mud in the spray tank is sprayed on the sandy land, promptly curable desert surface prevents that husky body from flowing, and also can prevent sandstorm.
Described colloid mud can be selected the colloid mud that viscosity is big on the loess plateau.
Perhaps described colloid mud also can be selected the colloid mud that viscosity is big in the Yellow River.
The present invention breaks into colloidal substance with the big colloid mud of viscosity, is sprayed at the sandy land surface and reaches the purpose of fixing the sand, and cost is low, is convenient to operation, and instant effect has no side effect, and is pollution-free, do not influence the growth of plant.
The present invention can be used for the seedling phase sand prevention in farmland, and the protection seedling is not blown away by dust storm, and simultaneously, it keeps the effect of fertilizer efficiency in addition.
The present invention also can be used for large-scale control of desert.
The specific embodiment
Embodiment 1
1), the preparation of colloid mud: colloid mud that viscosity on the loess plateau is big and water are 1: 15 ratio by weight, are mixed into colloidal substance, squeeze in the spray tank;
2), spraying: press 0.5kg/m
2Quantity for spray the colloid mud in the spray tank is sprayed on the sandy land, promptly curable desert surface prevents sandstorm.
Embodiment 2
1), the preparation of colloid mud: colloid mud that viscosity in the Yellow River is big and water are 1: 15 ratio by weight, are mixed into colloidal substance, squeeze in the spray tank;
2), spraying: press 1kg/m
2Quantity for spray the colloid mud in the spray tank is sprayed on the sandy land, promptly curable desert surface prevents that husky body from flowing, and also can prevent sandstorm.
The present invention breaks into colloidal substance with the big colloid mud of viscosity, is sprayed at the sandy land surface and reaches the purpose of fixing the sand, can be according to actual conditions, and the wind major region, the thickness of spraying can thick point, the area that wind is little, the thickness of spraying can point.Thereby cost of the present invention is low, is convenient to operation, and instant effect has no side effect, and is pollution-free, do not influence the growth of plant.
It should be noted that at last: obviously, the foregoing description only is for example of the present invention clearly is described, and is not the qualification to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being extended out thus or change still are among protection scope of the present invention.
