Abstract
The invention relates to a soil improvement method for saline-alkali soil. The method is characterized by comprising the following processing steps: bulldozing, i.e. shoving soil on the surface of the saline-alkali soil which needs to be improved; pipe laying, i.e. laying leaky pipeline systems on the ground of which the surface soil is shoved; stone laying, i.e. laying a broken stone layer in gaps between the pipeline systems; fertilizer covering, i.e. covering an organic fertilizer layer on the cobblestone layer; soil leveling, i.e. raking the surface soil in the bulldozing step broken and then covering the organic fertilizer layer with the broken surface soil; alkali washing, i.e. wetting the surface soil with water or aqueous solution to wash out excessive saline-alkali substances in the soil. The broken stone layer in the soil improvement method cuts off salt conveying from soil capillary water to the ground surface, takes a good salt accumulation prevention effect after washing out alkali and is beneficial to durability and stability of improving the saline-alkali soil; moreover, microbiological degradation of the organic fertilizer also can reduce alkalinity of the soil; the method can be used for comprehensively treating the saline-alkali soil.
Description
Technical field
The present invention relates to soil improvement field, particularly to a kind of saline-alkali soil improvement method.
Background technology
Salt-soda soil is a species of salt aggregation, refers to that contained salinity inside soil has influence on the normal life of crop
Long, according to UNESCO and food and agricultural organization's incomplete statistics, the area in whole world salt-soda soil is 9.5438 hundred million public affairs
Hectare, wherein China is 99,130,000 hectares.China's alkaline earth and the formation of alkali-affected soil, most of accumulative with Carbonates In Soil
Relevant, thus basicity is generally higher, serious salt affected soil regional plant can hardly be survived.At present, domestic to salt-soda soil
Processing method generally comprise salt discharge method and pressure salt method etc., but they all have weak point, and for example, salt discharge method is by using
Substantial amounts of fresh water is rinsed for a long time to salt-soda soil and so that the salinity of saline and alkaline ground surface is reduced.Pressure salt method is to utilize natural precipitation
Or artificial flood irrigates, partly saline and alkaline hole along soil, crack etc. is made to permeate downwards, by the salinity of topsoil with water band
To bottom, although said method can make the salinity of saline and alkaline surface layer reduce, it is permanent not to keep, and needs substantial amounts of
Water source, therefore, urgently need to develop a kind of water consumption little and can be permanently effective improvement salt-soda soil method, salt can be made
The planting technique in the suitable gardens in alkali ground.
Content of the invention
The technical problem to be solved is to provide a kind of saline-alkali soil improvement method.
The technical problem to be solved is achieved by the following technical programs:
A kind of saline-alkali soil improvement method, including following process step:
Bulldoze, described soil-shifting is that the salt-soda soil surface soil improveing need is pushed open;
Pipe laying, described pipe laying is the tubing laying seepage on the ground pushing topsoil;
Paver, described paver is to lay a metalling in the gap of tubing;
Lid is fertile, and described lid fertilizer is to cover a fertilizer bed of material on cobblestone layer;
Grading, described grading is that the table soil harrow broken in soil-shifting step is then covered by fertilizer layer;
Soda, described soda is with water or solution immersion topsoil, salt alkaloid substance excessive in eluting soil.
Preferably, described metalling is the cobblestone layer of particle diameter 0.5-3cm, and rubble thickness is 3-10cm.
Preferably, described fertilizer thickness of feed layer is 3-10cm.
Preferably, described tubing is interlocked the latticed of connection for pipeline transverse and longitudinal, and the area of the little lattice of any of which is
0.5-1.5 square metre, this tubing at least provided with one can inject effusion be opened on earth's surface, pipe diameter is 3-
7cm, tube wall has the weepage holes that aperture is that 0.5-2mm does not wait.
Preferably, the table soil thickness on the described fertilizer bed of material is more than 30cm.
Further, described soda step can be implemented 1-4 time according to salinization of soil degree, 3-5 days after each soda
Table soil is implemented to implement soda next time again within 1-3 days after harrow broken is processed.
Preferably, described effusion is dry yeast and water quality than the aqueous solution for 1:2000-5000.
Preferably, mistake 50 mesh sieve containing humic acidss more than 60% can be mixed in described grading step in the table soil of harrow broken
Weathered coal, mixed ratio be every square metre 0.5-3 kilogram.
Preferably, the soil after soda process can put into Lumbricuss loam, and supply volume is not less than 20 for every square metre
Only.
The invention has the following beneficial effects:
1. the metalling of the present invention blocks soil capillary water and conveys salinity to earth's surface, serves and prevents the accumulation of salt in the surface soil well
Effect, be conducive to salt affected soil improvement persistency and steadiness.
2. the fertilizer bed of material of the present invention is laid on metalling, and fertilizer fertilizer forms humic through microbial decomposition, conversion
Matter, can improve the buffer capacity of soil, and can act on formation sodium humate with sodium carbonate, reduce surface soil alkalinity.With pipeline system
The seepage of system, moistening, decomposition rate quickening, and in effusion, insert dry yeast, accelerated decomposition speed.
3. the present invention mixes the weathered coal of mistake 50 mesh sieve containing humic acidss more than 60% in table soil, for topsoil
Saline and alkaline neutralization serves good effect, and the loam plus Lumbricuss, and the improvement for topsoil salinization of soil is entered
One step is consolidated.
Brief description
