Abstract
The present invention relates to saline-alkali soil conditioners and preparation method thereof, the saline-alkali soil conditioner is made of sulfuric acid modified diatomite, humic acid, ground phosphate rock, its preparation method includes being scattered in diatomite powder in the sulfuric acid of 20% concentration, when 80 90 DEG C of heating stirrings 8 are small, after standing overnight, it is cleaned with filter membrane repeated filtration and deionized water until supernatant is neutrality, electric heating drying obtains sulfuric acid modified diatomite, is mixed according still further to ratio addition humic acid, ground phosphate rock.The Product Process of the present invention is simple, low raw-material cost, and for reducing soil salt, alkalescence, improving soil aggregate structure and nutritional ingredient etc. has remarkable result.
Description
Technical field
Patent of the present invention is related to salt affected soil improvement field, more particularly to saline-alkali soil conditioner and preparation method thereof.
Background technology
Salt affected soil refers to that salinity in soil exceeds the accommodation of normal plant, simultaneous pH it is higher into
The general name of a kind of soil of alkalescence.The salinity of high concentration and high pH cause soil physico-chemical property to deteriorate, in soil environment plant and
Microbial survival is difficult, necessitates so as to carry out soil improvement to it.Salinity is generally soluble easily in water, can by the flowing of water and
It takes away, so pressure salt of pouring water becomes the important means of soil salt discharge, but pressure salt of pouring water not only causes the significant wastage of water resource, also
It can make a part of nutrient element loss in soil.Chemical modifying measure have the advantages that it is quick, easy to operate, it is and extensive
It uses, but in existing patented technology, or modifying agent ingredient is often excessively complicated, is unfavorable for promoting the use of or modifying agent sheet
The soluble chemical ingredient of body adds the salinity of soil or does not account for the improvement of soil physics structure again, so as to cause
It is palliative.
The content of the invention
The purpose of the present invention is overcoming existing deficiency, a kind of physicochemical property that can realize salt affected soil is provided and is changed
Salt affected soil improvement that is kind, reducing salinity, sweetening of the soil alkalescence.
To achieve these goals, the present invention provides a kind of saline-alkali soil conditioners and preparation method thereof.
A kind of saline-alkali soil conditioner, it is characterised in that the weight percent of its each component is：Sulfuric acid modified diatomite 60-
80%, humic acid 10-15%, ground phosphate rock 10-15%；
A kind of preparation method of saline-alkali soil conditioner, which is characterized in that include the following steps：
(1) diatomite powder is scattered in the sulfuric acid of 20% concentration, when 80-90 DEG C of heating stirring 8 is small, stood overnight
Afterwards, supernatant is outwelled, it is spare；
(2) plus after deionized water cleaning, used membrane filtration, cleaning filtering is until supernatant is neutral repeatedly, finally
It to the substance electric heating drying after filtering and grinds, obtains sulfuric acid modified diatomite；
(3) sulfuric acid modified diatomite, humic acid, ground phosphate rock are installed into weight fraction 60-80%, 10-15%, 10- respectively
15% is mixed, and obtains modifying agent finished product.
Beneficial effects of the present invention：Sulfuric acid modified diatomite in patent of the present invention is porous acid adsorption environmental protection material,
It adsorbs energy-absorbing and is greatly improved compared with ordinary silicon diatomaceous earth, simultaneous with acid ion, can not only quickly and effectively exchange adsorption drop
Low soil salt, moreover it is possible to which sweetening of the soil alkalescence achievees the purpose that inhibit soil salt and neutralizes alkalescence, and humic acid can be soil
Crumb structure kernel is provided and neutralizes the double action of alkalescence, achievees the purpose that soil physics structural improvement, ground phosphate rock can rise
To the effect of sustained release phosphorus, calcium nutritional benefit element.Soil conditioner in the present invention can integrate improvement soil physico-chemical property, material
Proportioning is simple, of low cost, derives from a wealth of sources, convenient for promoting the use of.
Specific embodiment
Embodiment 1：Diatomite powder is scattered in the sulfuric acid of 20% concentration, when 80-90 DEG C of heating stirring 8 is small, stood
After overnight, supernatant is outwelled, it is spare；After deionized water is added to clean, used membrane filtration, during cleaning filtering is to supernatant repeatedly
Until property, finally to the substance electric heating drying after filtering and grind, obtain sulfuric acid modified diatomite；By sulfuric acid modified diatomite,
Humic acid, ground phosphate rock are installed weight fraction 70%, 15%, 15% are mixed respectively, obtain modifying agent finished product.
Embodiment 2：Diatomite powder is scattered in the sulfuric acid of 20% concentration, when 80-90 DEG C of heating stirring 8 is small, stood
After overnight, supernatant is outwelled, it is spare；After deionized water is added to clean, used membrane filtration, during cleaning filtering is to supernatant repeatedly
Until property, finally to the substance electric heating drying after filtering and grind, obtain sulfuric acid modified diatomite；By sulfuric acid modified diatomite,
Humic acid, ground phosphate rock are installed weight fraction 80%, 10%, 10% are mixed respectively, obtain modifying agent finished product.
The embodiment of the present invention is described in detail above, but the content is only presently preferred embodiments of the present invention,
It cannot be identified as limiting the practical range of the present invention.All all the changes and improvements made according to the present patent application scope
Deng, should all still be attributed to the present invention patent coverage within.
