Abstract

The invention discloses one kind to improve soil salt-soda soil restorative procedure, comprises the following steps：1）Rinse：Chisel one layer depth 2.3 3.4m irrigation canals and ditches are dug around soil to be repaired, one layer of cement plate is inserted on irrigation canals and ditches；Water is extracted using suction pump to be rinsed soil to be repaired, the cycle of flushing rinsed once for 47 days, continuous flushing 7 11 times.The present invention, which realizes, is constantly turned over and is sprinkled renovation agent to soil, enables to the soil layer in renovation agent and salt-soda soil to be well mixed, and so as to which renovation agent can enter the bottom of soil layer, is easy to repair the salt-soda soil of ground depths；Simultaneously after crops are gathered in, the plant ash after burning is backed among salt-soda soil, can greatly improve the acid-base value in salt-soda soil, so as to improve the property in soil, is easy to the later stage to plant again.

Description

Improve soil salt-soda soil restorative procedure

Technical field

The invention belongs to land remediation technical field, and soil salt-soda soil restorative procedure is improved more particularly, to one kind.

Background technology

Salt-soda soil is a species of salt aggregation, refers to that the salinity contained by inside soil has influence on the normal life of crop Long, from soil texture, salt-soda soil is all knotts clay, and gas permeability, the seepage of water of soil are very poor, and salinity is blended in knotts clay In, it is difficult to be separated, cause to precipitate year by year, saliferous more and more higher, but existing salt-soda soil is repaired when repairing Not thoroughly, all it is often the soil property on rehabilitating soil surface；After the time one is grown, the salinity of the soil of bottom will come back to Top layer；Simultaneously during conventional land restoration, also can on salt-soda soil Planting Crops, but by crops harvesting walk After, root system is just left behind, but the stalk of crops is not utilized well, can cause the waste of resource.

The content of the invention

The present invention is for overcome the deficiencies in the prior art, there is provided repairs in a kind of improvement soil salt-soda soil for making full use of resource Method.

To achieve these goals, the present invention uses following technical scheme：One kind improvement soil salt-soda soil restorative procedure, bag Include following steps：

1）Rinse：One layer depth 2.3-3.4m of chisel irrigation canals and ditches are dug around soil to be repaired, one layer of cement plate is inserted on irrigation canals and ditches； Water is extracted using suction pump to be rinsed soil to be repaired, the cycle of flushing rinsed once for 4-7 days, continuous flushing 7-11 It is secondary；

2）Deep ploughing：Soil memory to be repaired is turned over, the process turned over needs progressively to be turned over to center from periphery；Turning over Plough after completing and soil to be repaired is plowed using ploughing machine；Soil to be repaired is carried out again after completion of plowing Secondary flushing；Use sprinkles renovation agent after completion is rinsed；

3）The configuration of renovation agent：From calcium oxide 3-6 parts, silica 21-23 parts, aluminum oxide 5-7 parts, sulfur trioxide 1-1.5 Part, iron oxide 5-9 parts, magnesia 0.3-0.9 parts, titanium dioxide 0.1-0.5 parts, potassium oxide 0.6-1.4 parts, manganese oxide 0.4- 0.7 part, sodium oxide molybdena 2-7 parts and water 35-47 parts mix, and then stand three days, then barrelling is stand-by；

4）The reparation in salt-soda soil：By step 3）In renovation agent be spread on salt-soda soil to be repaired, then using ploughing machine to soil Ground is turned over, and completes to cause that soil is dry in drying in the sun afterwards turning over, the soil dried is turned over again, Turn over the crop for planting Salt And Alkali Tolerance after completing on soil；After later stage farming harvesting, stalk is rekindled, then will Plant ash after burning is from being newly played back among soil to be repaired.

The present invention, which realizes, is constantly turned over and is sprinkled renovation agent to soil, enables to renovation agent and salt-soda soil Soil layer be well mixed, so as to which renovation agent can enter the bottom of soil layer, be easy to repair the salt-soda soil of ground depths It is multiple；Simultaneously after crops are gathered in, the plant ash after burning is backed among salt-soda soil, can greatly be improved The acid-base value in salt-soda soil, so as to improve the property in soil, it is easy to the later stage to plant again.

Further, step 4）Described in dry need dry untill soil superficial drying；Done by drying to top layer It is dry, also in moisture state below its top layer, therefore it is easy to turning over for later stage, while also ensure that the renovation agent of underground will not can Saline and alkaline in soil is repaired.

Further, need manually to screen out the organic matter for being not easy to degenerate during turning over；By manually screening out not The organic matter easily degenerated, it can ensure in soil to be not in the material do not degenerated when later stage farming, so that it is guaranteed that kind The plant of plant can be deep into underground and be absorbed to more nutrient, while protect environment.

In summary, the present invention, which realizes, is constantly turned over and is sprinkled renovation agent to soil, enables to repair The soil layer in agent and salt-soda soil is well mixed, and so as to which renovation agent can enter the bottom of soil layer, is easy to the salt to ground depths Repaired alkali；Simultaneously after crops are gathered in, the plant ash after burning is backed among salt-soda soil, can Greatly improve the acid-base value in salt-soda soil, so as to improve the property in soil, be easy to the later stage to plant again.

Embodiment

In order that those skilled in the art are better understood from the present invention program, it is right below in conjunction with the embodiment of the present invention Technical scheme in the embodiment of the present invention carries out clear, complete description.

Embodiment one：

One kind improvement soil salt-soda soil restorative procedure, comprises the following steps：1）Rinse：One layer of chisel is dug around soil to be repaired Deep 3.4m irrigation canals and ditches, one layer of cement plate is inserted on irrigation canals and ditches；Drainpipe made of a polyethylene is connected in the lower end of irrigation canals and ditches；Use Suction pump extracts water and soil to be repaired is rinsed, and the cycle of flushing rinsed once for 7 days, continuous flushing 11 times；2）It is deep Plough：Soil memory to be repaired is turned over, the process turned over needs progressively to be turned over to center from periphery；And turning over Need manually to screen out the organic matter for being not easy to degenerate in journey；Complete afterwards to carry out soil to be repaired using ploughing machine turning over Plow；Flushing again is carried out to soil to be repaired after completion of plowing；Use sprinkles renovation agent after completion is rinsed.
