Abstract
The invention puts forward a method for transforming desert into fertile farmlands. The main characteristics are as follows: mountain loess is utilized in the construction of a dam and a muddy water reservoir on the upstream loess plateau of the desert, the dam is broken to lead muddy loess water into desert plots, the muddy loess water freely flows to flood the desert plots, so that the desert plots can be transformed into fertile farmlands plot by plot, consequently, the muddy loess water flushing down from the loess plateau is intercepted, and thereby cannot flow into rivers, so that flood hazard is reduced, moreover, the muddy loess water can be utilized to replenish the desert with loess and water to change the structure of the desert, and thereby can help to transform the desert into fertile farmlands in a short time along with other desert control measures, as a result, the hazard is changed into benefit, and the flood hazard control investment is saved.
Description
Technical field
The invention belongs to agricultural technology field, relate to soil improvement method, be specifically related to a kind of method of transforming desert into fertile farmlands.
Background technology
The desert area of China is big, and provinces and regions such as the Xinjiang of the northwestward, Qinghai, Gansu, the Inner Mongol particularly, large-area desert not only can not be as kind of the plants of ploughing, and causes disaster to the locality.
Control of desert is transformed, and is a huge engineering and a difficult problem.For many years, people take to build shelter belt, or plant drought enduring plant in the desert, and to check winds and fix drifting sand, though obtained certain effect, the desert after fixing the sand in a short time can't be transformed into the good farmland, arable land.
And spread all in the provinces and regions, northwest in desert, large-area loess plateau, mountain, loess plateau, a large amount of loess by rain drop erosion after, muddy loess water flows into rivers, and the riverbed is raised in the alluvial river course, cause flood damage, people drop into huge human and material resources, financial resources again, and build huge hydraulic engineering and administer rivers, also be a long-term task.
Summary of the invention
The inventor through a large amount of investigation and investigation, is concerned about large-area desert idle in the author's long practice activity, and cultivated area is in continuous minimizing, purpose is to propose a kind of method of transforming desert into fertile farmlands, by engineering measures to reform desert, makes it progressively to transform as the good farmland.
The technical solution used in the present invention is, utilizes loess to build the loess dam by laying bricks or stones on the mountain, loess plateau of upstream, desert, builds the muddy water storehouse, and the flood irrigation of plot, desert is introduced with loess muddy water at least once broken dam, progressively is transformed into the good farmland.
For rugged desert, through arrangement, the muddy water gravity flow flood irrigation of getting off is convenient to draw in plot, smooth one-tenth desert;
For plot, desert far away, distance muddy water storehouse, muddy water be difficult to from purling and, link to each other with the muddy water storehouse and to build muddy water and carry channel, the flood irrigation of flowing automatically is again come in the conveying of loess muddy water.
The present invention takes technique scheme and measure, the desert is transformed, build the muddy water storehouse owing on the loess plateau of upstream, desert, utilize on the mountain loess to build a dam, both tackled the loess muddy water that the loess plateau upper punch brushes down, make it not flow into rivers, the silting river course, be used to water the desert again, mend into loess and water to the desert, changed the constituent in desert, not only help cooperating other control of desert measures, the desert block-by-block is being transformed into piecewise the good farmland that can plant plant than short-term, and become to suffer from for sharp, alleviated the flood of downstream, loess plateau rivers, saved the investment of improvement flood.
The specific embodiment
On the mountain, loess plateau of upstream, desert, utilize loess a large amount of on the mountain, the loess dam is built in many places, builds up the muddy water storehouse of a plurality of big or small storage capacity, break the loess dam during use, muddy water is introduced through smooth plot, desert gravity flow flood irrigation, behind the empty storehouse of muddy water, also can be continued the muddy water storehouse in the muddy water storehouse in the former address, secondary interception savings muddy water, broken once more dam draws muddy water to be gone into the plot, desert and carries out the secondary flood irrigation, progressively prolongs widely, consolidates and enlarge the area of improveing the desert.
The muddy water that links to each other with the muddy water storehouse is carried channel, and the muddy water storehouse that links to each other with channel specially can be established in its muddy water storehouse, and its muddy water carries channel to build open channel, secret tunnel on ground, and also sky sets up tank or conveyance conduit on the ground; Set up total canal, sublateral canal separately; Its muddy water storehouse can utilize the muddy water storehouse of continuing; After improving desert took effect the plantation crops, muddy water storehouse and channel also can continue to bring into play project benefit, and further improvement or water conservancy irrigation are implemented in the plot after the improvement.
Claims (3)
1. the method for a transforming desert into fertile farmlands is characterized in that utilizing loess to build the loess dam by laying bricks or stones on the mountain, loess plateau of upstream, desert, builds the muddy water storehouse, and the flood irrigation of plot, desert is introduced with loess muddy water at least once broken dam, progressively transforms the good farmland.
2. the method for a kind of transforming desert into fertile farmlands as claimed in claim 1 is characterized in that for rugged desert, and through arrangement, the muddy water gravity flow flood irrigation of getting off is convenient to draw in smooth one-tenth plot;
3. the method for a kind of transforming desert into fertile farmlands as claimed in claim 1 or 2 is characterized in that for distance reservoir plot, desert far away, muddy water be difficult to from purling and, link to each other with the muddy water storehouse and to build muddy water and carry channel, the flood irrigation of flowing automatically is again come in the conveying of loess muddy water.
