Abstract
The invention provides a soil ventilation improving synergist containing iron tailings and a preparation method thereof. The soil ventilation improving synergist comprises, by weight, 1 part of tailings, 0.01-0.1 part of crop straws and 0.01-0.1 part of polyvinyl alcohol. After the soil ventilation improving synergist is added into the soil, soil trace elements can be added, soil aggregate is increased, porosity of the soil is increased, soil ventilation is improved, and improvement of activity of microorganisms and enzyme in the soil is promoted. Hydroxyl on a polyvinyl alcohol high molecular chain on the surface of a tailings particle can be attached to soil particles, and soil aggregate and fine pores of the soil are further increased. Crop straw particles processed through decomposing can improve a biochemical property of cohesive soil, provides abundant organic substances for the soil, stimulates the microorganisms in the soil to grow and move, and improves fertilizer retaining and fertility improving capacity of the soil. The soil ventilation improving synergist is low in cost, simple in preparation process, favorable for popularizing. Simultaneously, double effects of chemical modification and physical modification are achieved simultaneously, and the effects are remarkable.
Description
Technical field
The invention provides the ventilative improvement of a kind of soil synergistic agent and preparation method thereof, a kind of ventilative improvement of soil synergistic agent that contains iron tailings and preparation method thereof especially is provided.
Background technology
Because China is populous, the soil is not cultivated all the year round and is lain fallow the phase, causes Trace Elements in Soil to lack, and causes nutritive ingredient not enough, affects crop growth.Especially the general organic content of clayed soil is lower, and soil is dense, the water-permeable and air permeable ability, and crop yield is lower, need to improve output to the ventilative improvement of interpolation synergistic agent in the soil.
Mine tailing is the solid waste that bargh dumps in extractive metallurgy main raw material process, generally stores up in Tailings Dam.Mine tailing is a kind of non-renewable, available stock, mainly by silicate, aluminosilicate, carbonate minerals and micro-mineral composition.For many years, along with the continuing to increase and lack the approach that utilizes that effectively can consume in a large number mine tailing of mine tailing reserves, caused the accumulating amount of mine tailing and huge, wherein especially in the majority with iron tailings.The bulk deposition of mine tailing is contaminate environment not only, and takies the cultivated land resource of a large amount of preciousnesses.
On the other hand, China is large agricultural country, and the behind of huge grain yield is more huge agriculture byproduct, wherein take agricultural crop straw as main.Traditional treatment process is it to be acted as a fuel or feed is disposed, and the degree of recycling is very low.
The present invention is directed to the problems referred to above, utilize iron tailings and agricultural crop straw to prepare the ventilative improvement of soil synergistic agent, realize the recycling of the two.
Summary of the invention
The purpose of this invention is to provide a kind of ventilative improvement of soil synergistic agent that contains iron tailings.
Another object of the present invention provides a kind of preparation method who contains the ventilative improvement of the soil synergistic agent of iron tailings.
According to the ventilative improvement of the soil synergistic agent that contains iron tailings of the present invention, it is characterized in that, it is comprised of the raw material of following weight part proportioning:
1 part of iron tailings, agricultural crop straw 0.01-0.1 part, polyvinyl alcohol 0.01-0.1 part.
According to the ventilative improvement of the soil synergistic agent that contains iron tailings of the present invention, it is characterized in that, it is comprised of the raw material of following weight part proportioning:
1 part of iron tailings, agricultural crop straw 0.03-0.06 part, polyvinyl alcohol 0.05-0.1 part,
Wherein agricultural crop straw refers to maize straw, broomcorn straw.
According to the preparation method who contains the ventilative improvement of the soil synergistic agent of iron tailings of the present invention,
Weight part proportioning according to described raw material is carried out the following step:
(1), with agricultural crop straw after decomposing agent is processed, air-dry, become particle diameter less than the particle of 2mm through break process again, stand-by;
(2), iron tailings is sieved processing, screen out particle diameter greater than 50 purpose particles;
(3), with polyvinyl alcohol with after water mixes in the ratio of 1:25, be heated to 90-95 ℃, and fully stir;
(4), until polyvinyl alcohol all after the dissolving, polyvinyl alcohol water solution evenly is sprayed on the iron tailings particle after the screening in proportion, air-dry stand-by;
(5), the iron tailings particle that makes of agricultural crop straw particle that step (1) is made and step (3) mixes, and get final product.
According to the ventilative improvement of the soil synergistic agent that contains iron tailings of the present invention, it is characterized in that, it is comprised of the raw material of following weight part proportioning:
1 part of iron tailings, 0.036 part of agricultural crop straw, 0.05 part of polyvinyl alcohol,
Wherein agricultural crop straw refers to maize straw, broomcorn straw.
According to the ventilative improvement of the soil synergistic agent that contains iron tailings of the present invention, it is characterized in that, it is comprised of the raw material of following weight part proportioning:
1 part of iron tailings, 0.048 part of agricultural crop straw, 0.08 part of polyvinyl alcohol,
Wherein agricultural crop straw refers to maize straw, broomcorn straw.
The ventilative improvement of the soil synergistic agent that contains iron tailings of the present invention can by adjusting the raw material weight proportioning, satisfy different soil service requirementss.
The ventilative improvement of the soil synergistic agent that contains iron tailings of the present invention can be used by 150-500 kilograms every mu, can improve soil, can realize again the recycling of mine tailing and stalk.
After adding the ventilative improvement of the soil synergistic agent that contains iron tailings of the present invention in the soil, the mine tailing particle can improve Soil structure, can increase the content of Trace Elements in Soil, the improvement soil physical properties can reduce the soil weight, increase the quantity of coacervate in the soil, increase the porosity in the clayed soil, improve the ventilation property of soil, regulate three and compare, improve ground temperature, and then promoted the raising of Soil Microorganism and enzymic activity.And contain a large amount of hydroxyls on the high-molecular polyvinyl alcohol chain of mine tailing particle surface, and can be attached on the soil particle by hydrogen bond action, further increase coacervate quantity in the soil, and can increase the micropore in the soil, promote the root growth of crop.Increasing both production and income.Agricultural crop straw particle after the processing of becoming thoroughly decomposed can be improved the biochemical characteristic of clayed soil, for soil provides abundant organic matter, stimulate growth and the activity of Soil Microorganism, microbial biomass and bacterial number are increased, improve the fertilizer-preserving ability of soil and increase soil fertility.
The ventilative improvement of the soil that contains iron tailings of the present invention synergistic agent is with low cost, and preparation technology is simple, is convenient to popularize; Can play simultaneously chemical modifying and physically improved dual function, successful.
