Abstract
The present invention discloses a method for improving salinized soil, especially for desalting salinized soil, and features that said method includes such technological steps as digging drainage ditch to surround the salinized soil area to be improved, deep ploughing, levelling, introducing fresh water onto the salinized soil by slurry pump to flush it section by section, and draining the water after the salt in soil is thoroughly dissolved.
Description
The present invention relates to the method on a kind of transformation salinity ground, especially a kind of desalination process of saline land.
In " saline-alkali soil forestation " that China Forest publishing house published in 1986, once disclose a kind of improving the soil and controlled the salt measure, taked the water conservancy project measure, promptly built irrigation and drainage system, the fresh water desalinization of soil by flooding or leaching, storage fresh water on saline-alkali land for leaching; Tillage control measure is promptly deep ploughed and is suned the earth which has been ploughed up, levels land, intertills and loosen the soil; Biological control measure is a green manuring.Comprehensive reformation is carried out in the saline land.This measure need drop into lot of manpower and material resources, and alkaline land improvement is needed a very long process well, often needs the time of 3-5 even 7-8.
The object of the present invention is to provide a kind of easy and simple to handle, cost is low, utilizes less fresh water amount, makes the method for soil quick desalination.
Technical scheme of the present invention is: the ditch at first begins to rehearse, the soil that will improve impales, deep ploughing, leveling, with fresh water desalination is carried out in the saline land, this desalination process is, fresh water is introduced the saline land, closes on freshwater source with the slush pump utilization saline land burst is washed, when treating that salinity in the soil fully is dissolved in the irreducible water of the soil water and the free water, in time flushing water is entered in the drain ditch.
Before the saline land carried out desalination, apply wheat straw or stable fertilizer, repeatedly flushing of row is again planted plant then and is covered.
After adopting above-mentioned method for desalting salinized soil, because the saline land can influence the deep soil desalination after utilizing soil layer desalination about 30cm.Therefore the method taked of the present invention can make the soil desalination about 30cm preferably, and the salinity more than 80% can wash away with water, organic matters such as wheat straw are sneaked in the soil layer, become fertilizer through becoming thoroughly decomposed of a rainy season,, plant the wheat per mu yield then and can reach 300 kilograms through the soil that this method is transformed.So the soil-ripening of improvement is fast, content of organic matter cumulative year after year.Can become the good farmland through careful farming.After 2 years, survival rate reaches more than 85%.Salt content reduces to 3/1000ths by tens/1000ths, makes topsoil can satisfy anti-medium saline and alkaline plant growing.This method is less relatively with the fresh water amount, and cubic metre of earth amount of moving is little, and desalination is rapid, and cost is low, can large tracts of land utilization in the improvement of beach saline land, can also be used for urban afforestation.
Below in conjunction with embodiment the present invention is elaborated.
The ditch that at first begins to rehearse, the soil that will improve impales, deep ploughing, leveling, apply wheat straw or stable fertilizer, with fresh water desalination is carried out in the saline land, this desalination process is that fresh water is introduced the saline land, when treating that salinity in the soil fully is dissolved in the irreducible water of the soil water and the free water, close on freshwater source with the slush pump utilization,, and in time flushing water is entered in the drain ditch the flushing of saline land burst, row is flushing repeatedly, plants plant then and covers.
Claims (2)
1, a kind of method for desalting salinized soil, the ditch at first begins to rehearse, the soil that will improve impales, deep ploughing, leveling are carried out desalination with fresh water to the saline land, and it is characterized in that: this desalination process is, fresh water is introduced the saline land, close on freshwater source to saline land burst flushing with the slush pump utilization, when treating that salinity in the soil fully is dissolved in the irreducible water of the soil water and the free water, in time flushing water is entered in the drain ditch.
2, method for desalting salinized soil according to claim 1 is characterized in that; Before the saline land carried out desalination, apply wheat straw or stable fertilizer, repeatedly flushing of row is again planted plant then and is covered.
