Abstract
The invention discloses a desalting method of saline-alkali soil. The desalting method comprises steps of ploughing and leveling a to-be-managed field after crops are harvested in winter; after paving soft materials with fine holes, performing winter irrigation, and uncovering the soft materials after water in the field completely infiltrates downwards, at which time parts of saline-alkaline has been adhered to the surfaces of the soft materials; during sowing at the beginning of spring, arranging grooves with 10cm widths and 5 cm depths in 30 cm places of two sides of a sowing line; and laying drip irrigation drip irrigation belts and mulching films on the sowing lines, dropping water into the drop irrigation belts when water is short in the field. Water moves towards 30-40 cm periphery of the sowing lines with salt and enters the soft materials. Via the siphonic effect, the salt is taken to the surfaces of the soft materials. According to the invention, based on cultivation characteristics of arid regions, saline-alkaline in soil can be collected and removed without changing cultivation modes by use of the soil siphonic effect, so salt in the soil can be quickly and easily collected, an objective of improving soil quality can be achieved, and the desalting method is easy to operate and lower in cost.
Description
Technical field
The present invention relates to soil treatment field, be specifically related to a kind of saline-alkali soil desalination method.
Background technology
The improvement method in saline land, current arid area is mainly washing salinity by irrigation method, according to the rule of " salt comes with water, and salt goes with water ", water is poured in ground, form the water layer of certain depth on ground, the salinity in soil is fully dissolved, then drain from drain ditch the salinity dissolved.Thus reduce the salt content of soil.For to have abundant water resources and also there is the method adopting rice cultivation in the area not possessing washing salinity by irrigation, because after rice cultivation.By basining irrigation for a long time and.Draining is changed, and the salinity in soil just can be leached and discharge.Also have deep ploughing subsoiling method, add deep plough level, can accelerate to drench salt, prevent the accumulation of salt in the surface soil, strengthen keeping soil water ability, the nutrient situation of improvement soil.Be exactly finally soil moved in improve the original pressure alkaline process, soil moved in improve the original is exactly soil removal and replacement, and soil moved in improve the original can improve the physical property in saline land.Have and press down salt, pouring salt, pressure alkali and reinforcement.The effect of soil fertility.Soil salt content can be made to be reduced to the degree of unlikely damage to crops growth.
Said method at some areas effect not good or promote unfavorable, mainly cost is higher, implement complicated, to water source or hardware requirement high, require to abolish ridge in time when spring irrigation or winter irrigation as washing salinity by irrigation, otherwise because the siphonage of soil, the part spilling the water surface at first can cause salt accumulation by the capillary attraction large quantity of moisture of soil, saline and alkaline crystallization is there is at the end of irrigation, if the unprocessed direct plough of this part soil falls, the situation that the crops in this region can be caused to grow occurs.And also cannot rice cultivation for a long time for insufficient area, water source.Dark for underground alkali is likely dug by deep ploughing subsoiling, causes more serious salinization of soil.Soil moved in improve the original pressure alkali cost is high, larger for spread difficulty.
Summary of the invention
For solving the problem, the invention provides a kind of saline-alkali soil desalination method, in conjunction with arid biogeographic zone farming feature, under the prerequisite of not correcting tillage method, the object utilizing soil siphon principle to carry out centralized collection to soil alkaline to remove, reach cost-saving, conveniently promote.
For achieving the above object, the technical scheme that the present invention takes is:
A kind of saline-alkali soil desalination method, comprises the steps:
To wait after S1, in autumn crop gather that administering field plough falls, leveling, after spreading the punctulate flexible material of band, carries out winter irrigation, after water consumpation oozes completely down, takes flexible material off; Now part is saline and alkaline has been attached to flexible material surface;
S2, the beginning of spring are when sowing, in sowing, 30cm place, row both sides offers the wide 5cm zanjon of 10cm, and lay flexible material, irrigate band and mulch film is laid at kind of a row, when field lack of water, drip in irrigate band, and it is mobile to the peripheral 30-40cm place of kind of row that moisture carries salinity, enter flexible material, by siphonage, salinity is brought to flexible material surface.
Wherein, described flexible material includes but not limited to fibrous paper, plastic paper.
Wherein, described flexible material includes but not limited to the fiber paper-like materials with capillary class formation.
The present invention has following beneficial effect:
In conjunction with arid biogeographic zone farming feature, under the prerequisite not changing tillage method, utilize soil siphon principle to carry out centralized collection to soil alkaline and remove, can salinity in convenient and swift concentrated collection soil, reach the object improving soil soil property, simultaneously the method convenient operation, cost is lower.
Embodiment
In order to make objects and advantages of the present invention clearly understand, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
