Description

A kind of float stone aquifer that adopts is collected the method for rainwater and the application in alkaline land improving thereof
Technical field
The present invention relates to a kind of the adopt method of float stone aquifer collection rainwater and the application in alkaline land improving thereof, belong toIn soil improvement technical field.
Background technology
The content of organic matter of saline-alkali soil is few, and soil fertility is low, and physicochemical character is poor, and the yin, yang ion harmful to crop is many, doesThing is difficult for short seedling. Solonchak mainly refers to chloride or the higher salinization soil of sulfate, and soil is alkalescence, but pH value not necessarilyVery high. Alkaline earth refers to carbonate containing or heavy phosphatic soil, and pH value is higher, and soil is alkalescence.
The modification method in salt-soda soil is as follows: the desalinization of soil by flooding or leaching. The desalinization of soil by flooding or leaching is poured into water in salt-soda soil exactly, and soil salt is dissolved, logicalCross down to ooze and be discharged to saline and alkaline the solubility in topsoil in deep soil or drip washing is gone out, side is infiltrated gutter and is got rid of. SmoothSoil. Level land and can make moisture ooze under evenly, improve the effect that rainfall is drenched salt and irrigated the desalinization of soil by flooding or leaching, prevent soil spot shape salt marshChange. Deep ploughing is ploughed deeply. The distribution situation of salinity in soil is that surface layer is many, and lower floor is few, through ploughing, and can be in topsoilIt is following that salinity is turned upside down to topsoil, and soil less lower floor's saliferous is translated into surface. The arable layer of loosening of turning over, cuts off soil capillaryPipe, weakens soil water evaporation, effectively controls the soil accumulation of salt in the surface soil. The time of turning in salt-soda soil is spring and autumn preferably. Spring, autumnIt is heavier season of the accumulation of salt in the surface soil.
Under normal circumstances, soil underground water and topsoil water maintain certain dynamic equilibrium, and level of ground water is constant, top layerIon concentration in soil is relatively stable. When drought, soil evaporativeness increases, and the moisture in soil declines, and causesUnderground water is along moving on soil capillary, and the salinity in soil is also along with moisture moves simultaneously. After moisture evaporation, salinity is at soil, when salt ion reaches certain high concentration, just there is the salinization of soil in earth top layer accumulation. So most saline-alkali soil dividesCloth is in arid, semiarid zone. These area rainfalls in winter in spring are little, and rain time focused mostly in of short duration summer. Rainy seasonWhile there is flood, moisture is difficult to dredge rapidly, is difficult for again storing, and when freshwater resources waste, also causes soil erosion.
In the renovation technique in existing salt-soda soil, there is following shortcoming: (1) alkaline land soil pH, salt content, Cl-Content, Na+ Content, unit weight improved effect bad; (2) salt-soda soil moisture content, porosity improved effect are poor; (3) soil fertility is low; (4)After improvement, do not improve the water-holding capacity of soil.
Summary of the invention
The present invention be solve prior art exist deficiency, provide a kind of adopt float stone aquifer collect rainwater method andIts application in alkaline land improving, to realize following goal of the invention:
1, adopt the inventive method, reduce salt-soda soil pH, salt content, Cl-Content, Na+ Content, the unit weight of soil;
