Abstract

The invention relates to a soil improvement method for saline and alkaline land by creating leakage on the surface of the earth, comprising the following steps: leakage is created on a humus layer and a compact soil layer of the ground by shaft sinking until the shaft enters a hydrous sand soil layer; and coarse sandstone is filled in the shaft, and a pit mouth is covered by a grid plate sand net. Shaft sinking from the surface of the ground to the hydrous sand soil lay destroys the formation of capillary, thereby lowering the critical water level and eliminating salification. The soil improvement method for saline and alkaline land by creating leakage on the surface of the earth is simple, easy to carry out and low in cost; on one hand, the use of the shaft can lower the underground critical water level, destroy the formation of the capillary, prevent evaporation of underground shallow layer water and effectively solve the problem of formation of new saline and alkaline; and on the other hand, owing to the shaft sinking, a large quantity of water (such as rainfall)on the surface of the earth is caused to enter the underground water layer by the grid plate sand net and sandstone to clean the surface layer of the saline and alkaline land, so that the problem of evaporation and salifying of the surface water is completely solved, and the earthiness is effectively improved.

Description

The method of alkaline land by making leakage on earth's surface soil melioration
Technical field
The invention belongs to the method for soil melioration, particularly relate to a kind of method of alkaline land by making leakage on earth's surface soil melioration.
Background technology
The saline land is meant that soil contains the soil of excessive solubility salt.The whole world has nearly 10% land to be covered by dissimilar saline-alkali soil, is distributed in arid, semiarid zone mostly.The world has half in having now and irrigateing land approximately, has the threat of secondary salinization of soil; Simultaneously, by irrigation, draining, open up wasteland out large stretch of saline-alkali wasteland again.The reason of soil salinization of soil is because soil and underground water saliferous are too high, under strong surface evaporation effect, underground shallow seated groundwater is transported to the face of land through capillary and is evaporated, capillary is in the process of face of land water delivery, also the salinity in the water is taken to the face of land, after water is evaporated, soil salt rises by capillarity and accumulates in upper soll layer, salinity has just been stayed in the face of land and the ground thin solum, Ji Lei salinity is many like this, do not have the dilution of enough fresh water again and it is drained, just formed the salinization of soil.Crop growthing development is suppressed.At rainfall under the plentiful or irrigation conditions, soil salt can be by drip washing to the root layer, and drains into to hold by drainage system and let out the district, so that go into the sea.Salification and desalination all have substantial connection with the activity of water.At present, in order to prevent and treat the salinization of soil, major measure is controlled the phreatic water position exactly and is in below the critical groundwater table, specifically takes following measures: the dark formula box culvert of armored concrete conveyance canal; Dike, dam upstream face lining cutting add geomembrane and subtract and ooze; Soil cement adds geomembrane and subtracts and ooze; Vertical plastic spreading subtracts and oozes; Subtract to ooze with cutting and ooze draining and combine, control underground shallow-layer water level subcritical water level; Irrigate the measure that combines with draining; The canal irrigation measure that combines with well irrigation.But these measures all exist the desalination DeGrain, not thoroughly, investment is big, cost is high, engineering is complicated, be difficult for the shortcoming promoted.
Summary of the invention
The present invention is intended to overcome the deficiencies in the prior art, and a kind of method of alkaline land by making leakage on earth's surface soil melioration is provided.
Capillary in the stratum has the certain altitude ability to face of land water delivery, has surpassed this height, and it is transported to the face of land with regard to unable with underground water, and underground water just can not be evaporated, and surface soil just can salification, just can not produce the salinization of soil yet.When capillary when face of land carrying capacity is zero, the evaporation discharge of underground water on the face of land also is zero.People are called critical depth of water to the depth of groundwater table of this zero evaporation, and corresponding water level is called critical groundwater table.
The method of alkaline land by making leakage on earth's surface soil melioration of the present invention comprises: with the method for beating vertical shaft ground detritus soil layer and the close soil layer of matter are made leakage, in entering moisture sand layer.Beat vertical shaft to aquifer sand layer on ground, destroyed formation capillaceous, critical groundwater table is descended, stopped the phenomenon of salification.
As a further improvement on the present invention, insert grit in vertical shaft, well head covers the husky net of grate plate.
As a further improvement on the present invention, the described face of land is made leakage and is made of the vertical shaft more than a bite.
As a further improvement on the present invention, the bore of described vertical shaft is 10~500 centimetres.
As a further improvement on the present invention, to enter the degree of depth of moisture sand layer be 1~10 meter to vertical shaft.
The method of alkaline land by making leakage on earth's surface soil melioration of the present invention, simply, easily row, cost are low, the use of vertical shaft descends underground critical groundwater table on the one hand, has destroyed formation capillaceous in the soil, prevent underground shallow-layer evaporation of water, solved new saline and alkaline formation effectively; On the other hand, the cutting of vertical shaft makes a large amount of water in ground (as rainfall) enter water table by husky net of grate plate and sandstone, has cleaned the top layer, saline land, has thoroughly solved the problem of surface water salina stone deposition by evaporation, has improved soil property effectively.
