Description

A kind of method of saline land greening afforestation
Technical field
The present invention relates to afforestation technical field, specially a kind of method of saline land greening afforestation
Background technology
Saline and alkaline is the second largest abiotic stress for being only second to arid for plant.Salt-soda soil is the one of salt aggregation Individual species, refers to that the salinity contained by inside soil has influence on the normal growth of crop, according to UNESCO and grain farmer Incomplete statistics is organized, the area in whole world salt-soda soil is 9.5438 hundred million hectares, and wherein China is 99,130,000 hectares.China's alkaline earth With the formation of alkali-affected soil, major part is accumulative relevant with Carbonates In Soil, thus basicity is universal higher, and serious is saline and alkaline Soil region plant can hardly survive;Alkali using among process, briefly, light salt-soda soil, moderate can be divided into saline and alkaline Ground and heavy saline.Light salt-soda soil refers to its emergence rate in 70%-80%, and its salt content is below 3/1000ths;Geavy salt alkali Ground refers to its salt content more than 6/1000ths, and emergence rate is less than 50%;This middle block is exactly that moderate saline-alkali soil (is represented with pH value For:Slight alkaline land pH value is:7.1-8.5, moderate saline-alkali soil pH value is:8.5-9.5, heavy salinized ground pH value is:9.5 with On).Now with the development of science and technology, unfavorable one side should not be only seen, it should more be regarded as very precious soil Ground resource, because having many biological including plant, including microorganism, can adapt to this environment, and increasing section Skilled worker author is just put into the enthusiasm having one's bosom filled with and administered among the work in salt-soda soil, and the work for administering salt-soda soil is bound to obtain most Whole triumph.
The basic reason of saline-alkali soil formation 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, first salt discharge, the desalinization of soil by flooding or leaching, reduction soil salt content;Salt And Alkali Tolerance is planted again Plant, fertilizing soil;Last long-term cropping.Specific ameliorative measure is:Draining, irrigates the desalinization of soil by flooding or leaching, warps improvement, rice cultivation, Foster and apply fertilizer improvement, level land and chemical modifying;Saline-alkali soil is the general name of solonchak and alkaline earth.Solonchak refers mainly to chloride or sulfuric acid The higher salinization soil of salt, soil is in alkalescence, but pH value is not necessarily very high.Alkaline earth refers to carbonate containing or the phosphatic soil of weight Earth, pH value is higher, and soil is in alkalescence, and the content of organic matter of saline-alkali soil is few, and soil fertility is low, and physicochemical character is poor, harmful to crop Anions and canons it is many, crop be difficult promote seedling.The fertilization principle of saline-alkali soil is the control based on organic fertilizer material and efficient compound fertilizer The use of low concentration chemical fertilizer processed.Organic fertilizer contains substantial amounts of organic matter, and cushioning effect is played to harmful anions and canons in soil, Be conducive to root of hair, promote seedling.High-concentration compound fertilizer invalid components are few, and residual is few, but the consumption of chemical fertilizer every time can not be excessive, to keep away Exempt from the secondary salinization of exacerbation soil, applied to combine after chemical fertilizer and pour water, to reduce soil liquid concentration.
China's saline-alkali soil distribution is quite varied.Coastal area is the intermediate zone of continent and ocean, easily by storm tide, salt The influence of dirt, salt fog, and general physical features is relatively low, soil salt content and level of ground water are high, the glutinous weight of the soil texture, natural salt rejection rate It is low, easily bud into saline-alkali soil.The saline-alkali soil of coastal area large area seriously governs building for afforestation and ecological environment If.
The content of the invention
It is an object of the invention to provide a kind of method of saline land greening afforestation, 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 method of saline land greening afforestation, including with Lower step:
A, level land, leave certain gradient, drainage trenching, so as to washing salinity by irrigation;
B, deep ploughing are suned the earth which has been ploughed up, the glutinous weight of all quality, the soil of bad hydraulic permeability dysplasia, particularly former platform saline-alkali wasteland, in rain Season is turned over before arriving;
C, loosen the soil in time, the machine cultivated by machinery is regularly turned over to salt-soda soil;
D, sealing bottom type soil moved in improve the original raise ground and ground flowerpot type raises ground;
E, storage fresh water on saline-alkali land for leaching, washing salinity by irrigation, big cave soil moved in improve the original, bottom set separation layer and ooze pipe salt discharge, and pipeline is set by underground Salinity is discharged to;
F, to salt-soda soil increase apply chemical acidic waste calcium superphosphate, using a large amount of organic matters;
G, the green manure in salt-soda soil plantation salt tolerant and herbage, ground is raised to soil and ground flowerpot type soil moved in improve the original raises ground Measure;
H, select alkaline-resisting plant and carry out distribution plantation;
I, depths is buried and oozes pipe in soil, is oozed the laying of pipe and is oozed pipe using closed burial two-stage, it is direct that one-level oozes pipe Access open channel, the end of diode set catchment, well;
J, raise ground and divide into separation layer, utilize the discrepancy in elevation to carry out draining pouring, salt;
K, periodically salt-soda soil is digged, periodically using the method for washing filtering, that checks trees survives situation, to tree Woods carries out pulling out withered benefit green grass or young crops.
It is preferred that, one-level pipe horizontal range is 5m-15m in the step I, and burying depth is 1m-1.2m.
It is preferred that, diode uses brick pipe in the step I.
Compared with prior art, the beneficial effects of the invention are as follows:In the present invention, by the ameliorative measure of saline-alkali soil and landscape architecture skill Combine closely, both created colourful landscape for Urban Landscape Construction, and reached to improve the soil again and controlled the purpose of salt, so that It improves in terms of landscaping, greening, ecological benefits, urgent benefit, to promote and accelerating the gardens in saline-alkali soil area green Change cause contributes.
