Soil improvement fertilizer for improving sandy soil and preparation method thereof

Abstract

The invention discloses a soil improvement fertilizer for improving sandy soil and a preparing method thereof. The soil improvement fertilizer is prepared from coal gangue powder, polyisocyanate, potash feldspar, montmorillonite, carbamide, straw powder, peat humic acid, biochemical fulvic acid, protonated chitosan, konjaku flour, animal manure, seignette salt, sulfonates, monopotassium phosphate, nano titania, dispersant and a water retention agent. The soil improvement fertilizer for improving sandy soil is prepared by incinerating, grinding, filtering, ultrasonic high-speed dispersion, microwave treatment, prilling and stoving. The soil improvement fertilizer for improving sandy soil has the advantages of improving soil fertility effectively, reducing desertification degree and low production cost. The soil improvement fertilizer for improving sandy soil can meet the requirements of the industry. Moreover, the soil improvement fertilizer for improving sandy soil has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of environmental restoration, in particular to a soil restoration fertilizer for improving sandy soil quality and a preparation method thereof. Background technique [0002] Soil is an important part of the geographical environment, the material basis of agricultural production, and the basic resource for ecological environment construction, which is inseparable from human beings. However, due to people's unreasonable development and utilization of soil, soil erosion, desertification, desertification, salinization and soil pollution have caused land degradation and soil quality decline. Among them, the most prominent problem faced in most areas of our country is the phenomenon of soil desertification. [0003] Soil desertification refers to the process that good soil or usable land becomes sandy soil, or land even becomes desert. The main processes of soil desertification are wind erosion and wind accumula...

Problems solved by technology

[0004] At present, the existing soil improvement fertilizers or soil amendments used to improve sandy soil are mainly direct application of organic fertilizer or peat soil, and the improvement effect is not good.

Although direct application of organic fertilizer and peat soil alone as active ingredients can improve the fertility of the sandy land, but because it has no water retention function, it can only improve the fertility of the soil temporarily, but cannot improve the properties of the soil

In recent years, some organic polymer materials have also been used to improve sandy soil. These organic polymer materials can improve the structure and water retention of sandy soil, but they are expensive and not suitable for large-scale application.
