Problems solved by technology

At the same time, there are still some problems to be solved: ①Natural repair agents have limited repair effects, and there are problems such as short duration or limited reserves.
②The high cost of artificially synthesized polymer compounds and the potential risk of environmental pollution limit its wide application
③Single soil remediation agent has inadequacies such as incomplete remediation effect or negative impact to varying degrees

Embodiment 1

[0023] Crush 89g of straw into particles with a particle size of less than 40mm. The moisture content of the straw is 8%. After fermentation, it is mixed with 10g of nano-titanium dioxide and 1g of titanate and crushed to particles with a particle size of less than 0.5mm, and then crushed into particles with a jet mill. Particles with a diameter of less than 0.5 μm are obtained to obtain a titanium dioxide-loaded continuous tillage soil remediation agent.

Embodiment 2

[0025] Grind 91.2g of straw into particles smaller than 50mm, the moisture content of the straw is 5%, then mix with 8g of nano-titanium dioxide and 0.8g of titanate and crush to particles with a particle size of less than 1mm, and then use a jet mill to crush them into particles with a particle size of less than 1μm The granules are used to obtain the titanium dioxide-loaded continuous tillage soil remediation agent.

Embodiment 3

[0027] Grind 93.4g of straw into particles smaller than 30mm, the moisture content of the straw is 7%, then mix with 6g of nano-titanium dioxide and 0.6g of titanate and grind to particles with a particle size of less than 0.8mm, and then use a jet mill to crush into particles with a particle size of less than Particles of 0.8 μm were used to obtain the titanium dioxide-loaded continuous tillage soil remediation agent.

Abstract

The invention discloses a preparation method of a titanium dioxide supported remediator for continuously-ploughed soil and belongs to the technical field of soil remediator. The preparation method comprises the following steps: milling straws to form particles with the particle sizes being smaller than 50mm; then, mixing the particles with nanometer titanium dioxide and titanate, and milling the mixture to form particles with the particle sizes being smaller than 1mm; next, milling the particles by using a jet mill to form particles with the particle sizes being smaller than 1mu m to obtain the titanium dioxide supported remediator for continuously-ploughed soil, wherein the mass ratio of nanometer titanium dioxide to titanate to the straws is controlled at (2-10):(0.2-1):(89-97.8). The preparation method disclosed by the invention is simple; and the prepared remediator for the soil has a relatively good effect on repairing the continuously-ploughed soil, better utilizes the straws, belongs to an energy-saving and emission-reducing item and has an environmental effect.

Description

technical field [0001] The invention belongs to the technical field of soil remediation agents, and relates to a TiO2-loaded 2 The continuous tillage soil remediation agent specifically relates to a preparation method of a continuous tillage soil remediation agent loaded with titanium dioxide. Background technique [0002] Continuous tillage obstacle refers to the phenomenon that under normal management conditions, the same crops are planted on the same land for many years, resulting in poor crop growth, intensified pests and diseases, reduced yields, and low quality. There are different degrees of obstacles to continuous cultivation in many kinds of plants. Root Chinese medicinal materials, which account for 60% of cultivated medicinal materials, have prominent barriers to continuous cultivation. The soil that has been planted with ginseng needs a recovery period of about 30 years. Years to replant. There are obvious barriers to continuous cultivation of crops such as so...
