Embodiment 1
[0031] Raw material composition and weight proportioning are:
[0032] 1 part of iron tailings, 0.036 parts of corn stalks, and 0.05 parts of polyvinyl alcohol.
[0033] The preparation steps are:
[0034] (1) After the corn stalks are treated with a decomposing agent, air-dried, and then crushed into particles with a particle size of less than 2mm for use;
[0035] (2) Screen the iron tailings to remove particles with a particle size larger than 50 mesh;
[0036] (3) After mixing polyvinyl alcohol and water at a ratio of 1:25, heat to 90-95°C and stir thoroughly;
[0037] (4) After the polyvinyl alcohol is completely dissolved, the polyvinyl alcohol aqueous solution is evenly sprayed on the sieved iron tailings particles in proportion, and air-dried for later use;
[0038] (5) Mix the corn stalk particles prepared in the step (1) and the iron tailings particles obtained in the step (3) evenly to obtain the product.
[0039] Apply the soil air-permeable improvement synergi...
Embodiment 2
[0041] Raw material composition and weight proportioning are:
[0042] 1 part of iron tailings, 0.048 parts of corn stalks, and 0.08 parts of polyvinyl alcohol.
[0043] The preparation steps are the same as in Example 1.
[0044] Apply the soil air-permeable improvement synergist containing iron tailings of the present invention, apply 300 kilograms per mu, carry out the wheat planting test, compare and find that after using the soil improver containing iron tailings of the present invention, the wheat yield increases by 13.4%. The period is advanced by an average of 6 days, and the improvement effect is remarkable.

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 [0001] The invention provides a soil air-permeable improving synergist and a preparation method thereof, in particular, a soil air-permeable improving synergist containing iron tailings and a preparation method thereof. Background technique [0002] Due to the large population in our country, the land has been cultivated for many years without a fallow period, resulting in the lack of trace elements in the soil, resulting in insufficient nutrients and affecting the growth of crops. In particular, cohesive soil generally has low organic matter content, relatively dense soil, poor water and air permeability, and low crop yield. It is necessary to add air-permeable synergists to the soil to increase yield. [0003] Tailings are solid wastes discarded by mining enterprises during the process of refining the main raw materials for metallurgy, and are generally stored in tailings ponds. Tailings are a non-renewable and available resource, mainly composed of silica...
