Description

A kind of method of improved soil saline alkali
Technical field
The invention belongs to biological husbantry technical field, and in particular to a kind of method of improved soil saline alkali.
The content of the invention
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, according to UNESCO and food and agricultural organization's incomplete statistics, the area in whole world salt-soda soil is 9.5438 hundred million hectares, Wherein China is 99,130,000 hectares.The formation of China's alkaline earth and alkali-affected soil, it is most of accumulative relevant with Carbonates In Soil, Thus basicity is universal higher, and serious salt affected soil regional plant can hardly survive.
Various saline-alkali soil are formed under certain natural conditions, and its essence formed is mainly various ease of solubility salt Class makees redistributing for horizontal direction and vertical direction on ground, so that upper soll layer of the salinity in collection salt area is built up Get up.Influenceing the principal element that saline-alkali soil is formed has:1st, weather conditions, China northeast, northwest, North China it is arid, semiarid Area, precipitation is small, and evaporation capacity is big, and the salinity being dissolved in water easily gathers in upper soll layer.Summer rainwater is more and concentrates, greatly Amount soluble-salt is seeped into lower floor with water or flowed away, and here it is " desalination " season;Spring evaporation from topsoil is strong, in underground water Salinity rises with capillary and is gathered in upper soll layer, and this is main " accumulation of salt in the surface soil " season.Northeast, North China, semiarid zone Saline-alkali soil has obvious " desalination " " accumulation of salt in the surface soil " season, and the Northwest, because precipitation is seldom, the seasonal variety of soil salt Unobvious.2nd, formation of the geographical conditions landform positions height on saline-alkali soil influences very big, landform height directly affect surface water and The motion of underground water, also just move and accumulate substantial connection with salinity, in terms of megarelief, water soluble salt with water from eminence to Lower moves, and is gathered in low lying areas.Saline-alkali soil is mainly distributed on the Plain of interior basin, intermountain depression and flat impeded drainage Area, such as distant Plain of pine.From ninor feature(In subrange)From the point of view of, with megarelief antithesis, salinity often accumulates salt accumulation in soil situation Gather in the small convex of part.3rd, the soil texture and underground water, quality thickness can influence the speed and height of soil capillary water motion, In general, the loamy soil capillary rate of climb is very fast, and height is also high, and sand and clay salification are slow.Influence on groundwater soil The saline and alkaline key issue of earth is the height of level of ground water and the size of the degree of mineralization of ground water, and level of ground water is high, and salinity is big, easily Salification.4th, the soil for influenceing river and channel both sides of river and seawater, raises level of ground water because being oozed river side, promotes to accumulate Salt.Coastal area can form coastal saline-alkali soil because of Seawater immersion.5th, flood overflows during some improper place waterings of cultivation management Fill, or low laying areas only fills and do not arrange so that level of ground water rises and salification quickly, make it is original become salt-soda soil well, this Individual process is secondary salinization.To prevent secondary salinization, water conservancy projects wants irrigation and drainage supporting, forbids broad irrigation, will after pouring water Timely hoe.
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.Improvement of the prior art to salt-soda soil is divided into following aspects:Water conservancy improves, the row of Erecting and improving Fill system, accomplish to fill, arrange and separate, strengthen management of the use of water, strictly control groundwater level, rinse by pouring water, draw flood and warp, Salinity constantly in elution and exclusion soil.Agricultural technology improve, by deep plough, level land, be filled with soil moved in improve the original, lid grass, turn over silt, Gai Sha, applying organic manure etc. improve soil constituent and structure, strengthen soil moisture monitoring, accelerate salt leaching.Biological modification, kind Plant and turn over green manure herbage, straw-returning, using bacterial manure, plantation salt-tolerant plant, afforestation etc., increase soil fertility, improvement Soil texture, and improve agricultural microclimate, evaporation from topsoil is reduced, suppresses the accumulation of salt in the surface soil.Chemical modifying, to alkaline earth, alkali soil, Soviet Union Beat solonchak and apply the modifying agents such as gypsum, black alum, reduce or eliminate soil alkali point, improved soil physicochemical property.Various measures should Pay attention to comprehensive use, more to suit measures to local conditions, can just attain the results expected.
