Description
Technical field
The invention belongs to technical field of soil remediation, and in particular to a kind of nitrogenous soil conditioner and preparation method thereof.
Background technique
Zeolite (zeolite) is a kind of ore, is found in earliest 1756.The mineralogist Leiderkranz of Sweden mentions
(Cronstedt) discovery has a kind of natural aluminosilicate acid salt ore that can generate boiling phenomenon in calcination, therefore is named as zeolite.Boiling
Stone is divided into artificial zeolite and natural zeolite, the general chemical formula of zeolite are as follows: AmBpO2p·nH2O, structural formula A(x/q)[(AlO2)x
(SiO2)y]·n(H2O)；Wherein: the cations such as A Ca, Na, K, Ba, Sr, B are Al and Si, and p is cationic compound valence, and m is sun
Number of ions, n are moisture subnumber, and x is Al atomicity, and y is Si atomicity, and (y/x) usually between 1~5, (x+y) is unit crystalline substance
Tetrahedral number in born of the same parents.Zeolite has that unique pore structure, catalytic activity are high, thermal stability is strong, resistance to strong acid, and in room temperature item
Property is stablized under part.Zeolite has ion exchangeable, adsorbing separation, catalytic, stability, chemical reactivity, reversible de-
Aqueous, electrical conductance etc..Industrially often as molecular sieve, to purify or separate the substance of blending constituent, such as gas separation, stone
Oil purification, processing industrial pollution etc..The silicon content of zeolite reaches 50% or more, while it has colloidal property, and rheological property is urged
Change performance, absorption property, cation exchange property, dispersion performance and expansion character, the infiltration of acceleration nutritional ingredient can be passed through
And extension, Nutrient Absorption needed for making its crops greatly improve.The resource reserve of China's zeolite is big, and quality is high, type
It is abundant.Soil conditioner is produced using zeolite, China's zeolite resource abundant is can make full use of, is also the safety of agricultural product
It provides safeguard.
Currently, Xinjiang of China, northeast and Inner Mongol area face serious salinization of soil problem, perniciousness harm is caused largely
In, low farmland and peasant it is poor, large area soil resource is difficult to be utilized, overall productivity in agriculture decline seriously affects agriculture
The raising of industry production development and life of farmers level.Therefore, alkaline land improving utilizing works irrigated area rural area warp saline and alkaline for China
Sustainable and healthy development, management of national land, ecological environmental protection etc. help with extremely important realistic meaning.But it is existing to saline and alkaline
The recovery technique on ground is at high cost, and repairing effect is less desirable, has much room for improvement.
Summary of the invention
The purpose of the present invention is to provide a kind of nitrogenous soil conditioners and preparation method thereof, it is intended to solve existing salt-soda soil
Rehabilitation cost it is high, and technical problem undesirable with the improvement of zeolite rehabilitating soil merely.
For achieving the above object, The technical solution adopted by the invention is as follows:
One aspect of the present invention provides a kind of preparation method of nitrogenous soil conditioner, includes the following steps:
Zeolite is provided, zeolite progress pulverization process is obtained into zeolite powder；
The zeolite powder is dispersed in ammonium salt solution, mixed solution is obtained；
The mixed solution is separated by solid-liquid separation, solids is obtained；
The solids is dried, the nitrogenous soil conditioner is obtained.
The preparation method of nitrogenous soil conditioner provided by the invention, is first ground into powder for zeolite, then by zeolite powder
End is mixed with ammonium salt solution, and the zeolite of one side powdered form can preferably discharge the elements such as silicon-calcium-magnesium therein, on the other hand benefit
With the ion exchangeable and adsorptivity of zeolite, ammonium ion can be incorporated in the hole and duct of zeolite powder particle, so as to
To adjust the pH value and ion-exchange performance of final nitrogenous soil conditioner, and then increase product to the regulation effect in salt-soda soil,
The Element releases such as the silicon-calcium-magnesium in zeolite are more excited, provide nutrient for the plant growth in soil, while providing nitrogen for soil
Fertilizer ultimately forms the alkaline land improving soil conditioning for having both alkaline land improving and acting in terms of providing beneficial element two for crop
Agent, and the preparation method, using zeolite as primary raw material, raw material sources are extremely wide is not necessarily to calcine technology, have low energy consumption,
Therefore the simple feature of process flow has good industrial application value.
Another aspect of the present invention provides a kind of nitrogenous soil conditioner, and the nitrogenous soil conditioner is by of the invention above-mentioned
Preparation method is made.
Nitrogenous soil conditioner provided by the invention is made by the distinctive preparation method of the present invention, the nitrogenous soil conditioner
Surface soil alkalinity can be neutralized, the salt content of soil is reduced by ammonium ion exchange interaction, is thoroughly improved to reach alkaline land soil
Purpose, and the soil conditioner can excite silico-calcium magnesium elements possessed by zeolite materials itself, provide for plant growth feeding
Point, therefore, there is good application value.
Detailed description of the invention
Fig. 1 is the preparation method flow chart of the nitrogenous soil conditioner of the embodiment of the present invention.
Specific embodiment
In order to which technical problems, technical solutions and advantageous effects to be solved by the present invention are more clearly understood, below in conjunction with
Embodiment, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only used to explain
The present invention is not intended to limit the present invention.
On the one hand, the embodiment of the invention provides a kind of preparation method of nitrogenous soil conditioner, include the following steps:
S01: providing zeolite, and zeolite progress pulverization process is obtained zeolite powder；
S02: the zeolite powder is dispersed in ammonium salt solution, mixed solution is obtained；
S03: the mixed solution is separated by solid-liquid separation, solids is obtained；
S04: the solids is dried, and obtains the nitrogenous soil conditioner.
The preparation method of nitrogenous soil conditioner provided in an embodiment of the present invention, is first ground into powder for zeolite, then will
Zeolite powder is mixed with ammonium salt solution, and the zeolite of one side powdered form can preferably discharge the elements such as silicon-calcium-magnesium therein, another
Aspect utilizes the ion exchangeable and adsorptivity of zeolite, can be incorporated in ammonium ion in the hole and duct of zeolite powder particle,
So as to adjust the pH value and ion-exchange performance of final nitrogenous soil conditioner, and then increase improvement of the product to salt-soda soil
Effect, the more Element releases such as silicon-calcium-magnesium in excitation zeolite, provide nutrient for the plant growth in soil, while mentioning for soil
For nitrogenous fertilizer, the alkaline land improving soil for having both alkaline land improving and acting in terms of providing beneficial element two for crop is ultimately formed
