Description
Technical field
The present invention relates to alkaline land soil improving technology field, particularly relate to a kind of alkaline land soil biological modification
Agent and modification method.
Background technology
Saline Land is a worldwide problem, and it is arid, semiarid region that salinization of soil is distributed widely in the whole world
More than 100 countries and regions.China is the country that salinization of soil harm is the most serious, especially the Northwest
The provinces and regions such as Gansu, Ningxia, Xinjiang there occurs that salinization of soil endangers the most in various degree.
Saliferous generation evolution, is weather, topography and geomorphology, parent soil material and Textural layer, the hydrology
And hydrogeology constructs, pours water and cultivates the result of the combined factors effects such as cropping system.China's saline-alkali soil divides
Cloth district is the soil types according to it and weather conditions change decision, is divided into salting district, strand, Huang-Huai-Hai to put down
Crude salt stain district, desert and desert steppe salting district, the big type in four, salting district, grassland.
Being mainly characterized by containing more water soluble salt or alkaline matter of salt-soda soil.Owing to salinity is many, alkaline
Greatly, leaching loss, Soil structure are destroyed to make agron suffer, glutinous when showing themselves in that wet, hard time dry,
Soil table often has a white salinity accumulation, ventilates, permeable bad；Serious meeting causes plant wilt, poisoning and rotten
Root is dead, so salt-soda soil must be carried out soil improvement.
Alkaline land improving is a regular occupation, and China, since last century the eighties, has begun to explore
Carry out the improvement in salt-soda soil.Including adding modifying agent in soil, improve soil particle state, improve soil
Water retention property, changes the existence of salt and alkali component.But the effect of existing modifying agent still has weak point.

The change of reason soil salts density EC value.Result see table 2.
Table 2: use three steps to be used in conjunction the contrast (unit: mS/cm) of improvement soil salts density EC value
From table 2 and embodiment 5,6, the alkaline land soil biological modification agent of the embodiment of the present invention is with saline and alkaline
Ground soil chemistry modifying agent and/or physically improved dose of alkaline land soil are used in conjunction the improved effect to soil salt and have
Significantly improve.Visible, that the embodiment of the present invention is provided alkaline land soil biological modification agent and alkali ground soil
Physically improved dose and/or the formation Joint genetic improvement agent of alkaline land soil chemical improvement agent, it is possible to reach preferably to improve
Effect.When using Joint genetic improvement agent that alkaline land soil is carried out Joint genetic improvement, the applying of a rear modifying agent is only
Will be within the improved effect survival phase of the modifying agent above applied.In order to reach the effect of Joint genetic improvement as early as possible
Really, next evolutionary operation in Joint genetic improvement can be carried out after good completing can being changed above.
Each component in the embodiment of the present invention is commercially available the most from the market.Certainly also can obtain voluntarily.Such as mud
Charcoal soil can be obtained by burying the non-carbonization of upper layer within coal mines and become in the soil layer of coal.Fertile soil can by mountain from
Row obtains after screening and filtering again, or also may be used according to prior art fermentation acquisition.Conch meal can be by by marine
After the size-reduced cleaning such as shell or oyster shell, pulverizing after high-temperature calcination and obtain.Activated carbon is fine by branch or plant
Dimension etc. after anaerobic high-temp combustion pulverizing and obtain.Giving up after planting mushroom and gathered used by mushroom bag leftover bits and pieces
Abandon space bag, after the base material drying interior by it.Siliceous petrochemical industry powder is by containing silicon ore high temperature after crushed
Grind after calcining.Component and the weight/mass percentage composition of the most preferred siliceous petrochemical industry powder are as follows: silicon is the least
In 25.2%, protein is not less than 1.7%, and moisture is about 4.1%, and ferrum is not less than 3.72%, and potassium is not less than
1.4%, sodium is not less than 0.18%, and remaining is ash.Comprehensive trace element preferably at least includes following element,
And the weight/mass percentage composition of each element is as follows: boron >=2%, zinc >=2%, magnesium >=6.5%, sulfur >=9%.The most also
Other elements, such as ferrum, silicon and calcium etc. can be added on this basis.Silverskin can be by the leftover bits and pieces (rice of husk rice
Bran) in remove rice husk and after cracking rice.Calcium superphosphate can be obtained by rock phosphate powder and phosphoric acid mixed fermentation.
Beneficial microbe in the siliceous petrochemical industry powder of the embodiment of the present invention produces substantial amounts of many in reproductive process
Sugar, these glucides are the binding agents forming soil granular, and crumb structure makes loosing soil, cuts off soil
Earth capillary interstice, increases non-capillary pore gap so that saline-alkali soil accelerates to drench salt action, it is suppressed that the accumulation of salt in the surface soil,
Meanwhile, the fungus group organic acid that metabolism produces in soil accelerates the dissolving of insoluble salt in soil, right
Surface soil alkalinity serves the effect of neutralization.It can be effectively by salt-soda soil quick improvement, by the soil after improvement
The ground sustainable long-term farming time.
Physically improved dose of effective soil particle state of improving of the embodiment of the present invention, improves soil water-retaining performance,
Polyacrylic acid contained therein becomes to belong to complex polyelectrolyte particle, can fetter metal ion, reduces in soil
The content of soluble-salt, the acidity of self can neutralize the basicity of salt affected soil, reduces the ph value of soil.
Chemical improvement agent in the embodiment of the present invention and biological modification agent all contain substantial amounts of sulfur, silicon, magnesium,
The elements such as ferrum.Alkalescence in salt affected soil is mainly caused by potassium, sodium ion, the many sulfate with solubility of sulfur
State exists, if the potassium in alkaline earth, sodium ion are combined, produce and neutralizes reaction, make potassium, sodium ion become
The form of sulfate is leached, and can play the saline and alkaline dissolving soil, adjusts soil aggregate, from root
The effect of salt affected soil character is changed in basis.
The above, the only detailed description of the invention of the present invention, but protection scope of the present invention is not limited to
This, any those familiar with the art, in the technical scope that the invention discloses, can readily occur in
Change or replacement, all should contain within protection scope of the present invention.Therefore, protection scope of the present invention should
It is as the criterion with described scope of the claims.
