Description
Technical field
The invention belongs to the technical field of alkaline land soil improvement, be specifically related to a kind of saline-alkali land soil conditioner.
Background technology
Saline-alkali soil is the class soil that salinization or alkalization are formed, and comprises solonchak, alkaline earth and various salinized soil.In arid
And semiarid zone, salinity contained in underearth and underground water, due to evaporation from land effect, along with soil capillarity makes
Contained the waterborne of salinity is raised to surface layer, after moisture evaporation, makes salinity stay upper soll layer, builds up and form saltings.Strand
Stain is invaded due to resident seawater in area, and saltings is distributed more widely, and salt content is high, gathers too much solvable in upper soll layer or the soil body
Property salt.How dry saltings surface soil is, and in white, even form salt incrustation, be full of cracks of hardening, salinity is high, and corrodibility is strong, can destroy plant cell tissue, hinders plant-growth, and high salinity degree soil even can directly make root system of plant rot to cause plant dead.
The formation of China's alkaline earth and alkali-affected soil, major part is accumulative relevant with Carbonates In Soil, and basicity is generally higher, and serious salt affected soil regional plant almost can not be survived.Saltings is utilizing in the middle of process, briefly, can be divided into light saltings, moderate saline-alkali soil and heavy saline.What light saltings referred to it emerges very likely, and saltiness is below 3/1000ths; Heavy saline refers to that its saltiness is more than 6/1000ths, and seedling rate is lower than 50%, and moisture in soil pH value, more than 8.5, causes soil compaction, has restraining effect to the root system of crop, crop is not grown or grows unhealthy; Moderate saline-alkali soil is then between therebetween.At present along with the development of science and technology, should only not see disadvantageous one side, more it should be regarded as very precious land resources, because there are many biologies to comprise plant, comprise microorganism, can adapt to this environment, and increasing scientific worker is just putting into the enthusiasm of having one's bosom filled with among the work in improvement saltings, the work of administering saltings is bound to obtain final triumph.
Accessories during Binzhou is positioned at the inner edge in fan section, the Huanghe delta, inside faces the Yellow River, the external Bohai Sea, and its soil can be divided into three major types: alkaline soil, saline soil, sand.From the Huanghe valley more close to, its saline and alkaline is lower.Industrial sewage irrigates the pollution to soil.According to incompletely statistics, in Binzhou Prefecture, sewage irrigation area accounts for 10% of the total area, outside industry (papermaking, printing and dyeing, chemical industry etc.) sewage organic matter removal content, containing ammonia-state nitrogen, nitric nitrogen, nitrite nitrogen and the metal ion such as lead, copper, the enrichment in soil of these objectionable impuritiess, causes soil pollution.Particularly Irrigation District of Sewage, Xiaoqinghe River two sides, in soil, above-mentioned metal ion all detects, and from riverbank more close to higher.Oil-field development is to the pollution of soil.Accessories during Binzhou is the exploitation base of Shengli Oil Field, and thousands of mouthfuls of oil wells, water-injection plant, test satellite location, oil gathering station, storage tank are looked visible.Often beat a bite well and take up an area 0.2hm2 at least, nearly 1hm2 at most, before and after drilling well exploitation, a large amount of mud, landwaste, ground crude oil, pressure break agent, well-flushing acidizing fluid the like waste pile up well site, the long-term weathering loss that drenches with rain, in mud, the objectionable impurities such as oil, phenol, chromium immerses soil and causes secondary pollution, not only this season farm crop total crop failure, and have a strong impact on crop growth in later 2 ~ 3a, run into blowout and line fracture, substantial oil lands, and directly causes working district soil compaction accumulation of salt in the surface soil alkalization.

The Main Means administered, i.e. the irrigation and drainage system of Erecting and improving, improves the soil ins conjunction with plough deeply, target that soil removal and replacement, drip washing, the measure such as alluvial reach reduction arable layer saliferous.Although engineering measure application is comparatively extensive, also exists that the amount of labour used is large, input cost is high, it is limited to hold time or be limited to the series of problems such as water resources is nervous, and fundamentally can not reduce soil salt, must in conjunction with other
Measure is carried out.Duan Dengxuan etc. (2000) work out and carry out film every saline and alkaline engineering measure at saline-alkali wetland, namely utilize plastics
The effect of film water proof, blocks the path of saline and alkaline rising, reaches the effect of stable salt reduction alkali, but plastics film is difficult to degraded, band
Carry out the secondary pollution problem in soil.
Controlling the evaporation of soil surface moisture to reach, alleviating the object of salt and alkali component to earth's surface enrichment, have developed a series of ground mulching measure.Such as improving straw mulching, cauline leaf chopping covering or crop residue cover, membrane covering cement concrete mulching, asphalt emulsion covering etc., these methods serve good effect in suppression evaporation from topsoil even improvement of soil fertility, but or because becoming
This is too high, output is too low, or because of secondary pollution, or because of by resource limit, can not really promote aborning.
(2) chemical process improvement saltings
Chemical modifying is exactly apply some acid salts substances to improve the character in saltings, reduces the potential of hydrogen of soil, increases
Add the positively charged ion replacement ability of soil, reduce the saltiness of soil, strengthen the activity of Soil Microorganism and enzyme, promote plant
Root growth.Improve the physical properties of soil, increase soil aggregate, coordinate soil water fat gas heat, increase soil fertility.
(3) biological method improvement saltings
Traditional biological control measure improvement saltings, namely uses plant improvement saltings, easy to implement the method, remarkable in economical benefits.
Biological control measure can change the physical property of soil gradually, and Soil structure is changed, and quality becomes loose, and ventilative and water storage capacity strengthens.
In recent years due to the needs of coastland rapid economic development, the positive Devoting Major Efforts To Developing in part saltings, therefore also more and more obtains the attention of people to the improvement of alkaline land soil.There are some researches show that the low-solubility calcium salts such as gypsum, desulfurated plaster, calcium sulfite have significant alkaline land soil improving effect, after applying, effectively can promote the growth of plant, reduce soil pH and sodium potassium content.But these present methods are all with a large amount of consumption of natural resource; picked-up natural material or have passed through nature processing and manufacturing; cannot meet the requirement of environment protection and recycling economy, therefore finding a kind of technological method utilizing waste or Resource recovery to carry out alkaline land improving is the key point that this field is badly in need of breaking through.
