Description
Technical field
The present invention relates to technical field of land improvement, specially a kind of soil improvement method in salt-soda soil.
Background technology
Saline-alkali soil is distributed in that physical features is low flat, and level of ground water is higher, semi-moist, semiarid and arid hinterland.Underground
After soluble organic fraction in water rises to earth's surface along soil capillary, moisture evaporation, and salinity is then built up and forms saline-alkali soil.
Coastal saline-alkali soil is Seawater immersion formation.China's saline-alkali soil is mainly distributed on northwest, the low land in North, Northeast China Plain, lakeside
Or the lower edge of alluvial cone in the front area of mountains, and coastal area.Saline-alkali soil can be divided into solonchak, the major class of alkaline earth two.With chloride in solonchak
Change based on sodium and sodium sulphate, both salts are gathered in upper soll layer, form white salt incrustation.It is few containing soluble-salt in alkaline earth, B
Layer has solid column structure, rich in sodium carbonate.Therefore B layers are distributed more widely for the solonchak in strong basicity China.Alkaline earth is only fragmentary point
Cloth, in spring drought, a piece of white salt efflorescence is often presented in weak solonchak earth's surface, influences crop emergence or goes out full stand.It is to pass through to improve solonchak
The water resources industries such as draining, the desalinization of soil by flooding or leaching, and salt is improved with agricultural measures such as green manuring, organic fertilizer or kind rice.Improvement
Alkaline earth can gypsuming or sulphur, can also take sowing herbage or kind rice and to apply the aggregate measures such as gypsum.
The basic reason that saline-alkali soil is formed is that water regime is bad, so at the initial stage of improvement, emphasis should be placed on improvement soil
Above the water regime of earth.Typically it is carried out in several steps：Salt discharge, the desalinization of soil by flooding or leaching, reduction soil salt content first；Salt And Alkali Tolerance is planted again
Plant, fertilizing soil；Last long-term cropping.
The present invention is relevant with soil improvement method, especially with regard to a kind of soil improvement method in salt-soda soil.
The content of the invention
It is an object of the invention to provide a kind of soil improvement method in salt-soda soil, to solve to propose in above-mentioned background technology
The problem of.
To achieve the above object, the present invention provides following technical scheme：A kind of soil improvement method in salt-soda soil, including with
Lower step：
A, soil is subjected to processing of breaking ground first：
A, broken ground using excavator or plough, lower digging depth is more than 20cm；
B, carry out it is preliminary break ground, dig after, ground grading, certain gradient is left on the ground, after smooth
Deep ploughing is suned the earth which has been ploughed up on soil, at a distance of 35cm-45cm between adjacent upturned soil；
C, sealing bottom type soil moved in improve the original raises ground, and ground soil moved in improve the original is raised；
B, improved using washing：
E, clear water is largely irrigated in upturned soil, clear water rushes one end irrigation and flows to the other end, takes unidirectional irrigation；
Osmos tube is set in upturned soil f,；
G, after having irrigated water, base is made into using soil in the both ends of upturned soil, clear water was stored in upturned soil after the time of one end and opened
Upturned soil draining, one end continues slowly to irrigate clear water while draining；
Covered conduit salt discharge is dug, cobblestone is laid in covered conduit, coarse sand or chad are then covered on cobblestone, is then covered
Soil.
Preferably, chemicals improvement is carried out after washing improvement, comprised the following steps：
A, apply calcium superphosphate into soil, renovated soil while calcium superphosphate is applied, soil renovation is deep
Degree is more than or equal to 25cm；
B, increase substantial amounts of organic substance, such as sesbania, pale reddish brown lucerne place, sweet clover into soil again, while soil is turned over
Newly, organic matter and soil are sufficiently mixed, periodically apply organic matter into soil.
Preferably, plant improvement is carried out after chemicals improvement, comprised the following steps：
A, the green manure of grown on soil salt tolerant in renovation, herbage, various alkaline-resisting, salt tolerant plants, a large amount of plantations are planted
Turf, saline and alkaline ground surface is carried out to the covering of large area；
B, the spacing between planting is maintained at 100cm-120cm, and planting depth is 40cm-50cm
Compared with prior art, the beneficial effects of the invention are as follows：
The modification method cost that the present invention uses is low, quick.It is all fine to afforest and beautify effect, using physically improved method,
Water conservancy modification method, chemical modifying method, biological modification method, salt-soda soil is improved from various angles, effective fast prompt drop
Low soil saliferous, alkali number.
