Description

Technical Field

[0001] The present invention relates to the technical field of soil remediation materials, and in particular to a plateau soil remediation material and a preparation method thereof. Background Art

[0002] Due to the unique geographical and climatic conditions of the plateau, the soil environment is often fragile, characterized by compacted structure, low fertility, and weak microbial activity, severely restricting the development of local agriculture. Traditional soil improvement methods, such as simply applying chemical or organic fertilizers, while able to improve soil fertility to a certain extent, often fail to comprehensively address the multiple issues facing plateau soils. Long-term use can also lead to side effects such as soil compaction and nutrient imbalance.

[0003] In recent years, with the continuous development of soil remediation technology, researchers have begun to explore the application of new materials and technologies in soil improvement. Nanosilicate materials, due to their unique physical and chemical properties, are widely used in soil improvement, effectively improving soil structure, permeability, and water and fertilizer retention. Organic fertilizers, as traditional soil conditioners, are rich in organic matter and nutrients, which can promote soil microbial activity and enhance soil biological activity. However, using these materials alone often fails to achieve ideal remediation results.

[0004] At the same time, the role of plant growth hormones and rhizobia in promoting plant growth is also gaining increasing attention. Plant growth hormones can stimulate plant growth points, accelerate cell division and elongation, and improve plant photosynthesis efficiency. Rhizobia, on the other hand, can form a symbiotic relationship with legumes, fixing nitrogen in the air and providing an additional nitrogen source for plants. However, given the unique environment of the plateau, how to rationally mix these materials to prepare a remediation material that is both adapted to the plateau climate and can comprehensively improve soil and promote plant growth has become a pressing issue. Summary of the Invention

[0005] In order to solve the above problems, the present invention provides a plateau soil remediation material and a preparation method thereof.

[0007] a) 20-25 kg of nano-silicate material;

[0008] b) 1000kg of organic fertilizer;

[0009] c) 500-800g of plant growth hormone;

[0010] d) Plateau rhizobia + soil active bacteria mixture 1500ml-2000ml.

[0011] Furthermore, the plateau soil remediation material includes the following components:

[0012] a) 22 kg of nano-silicate material;

[0013] b) 1000kg of organic fertilizer;

[0014] c) 650g of plant growth hormone;

[0015] d) 1700ml of plateau rhizobium + soil active bacteria mixture.

[0016] Furthermore, the physical and chemical property parameters of the nano-silicate material include: pore diameter 50-200 nm, specific surface area 400-600 m3 / g.

[0017] Furthermore, the organic fertilizer comprises: 5 parts by weight of organic fertilizer produced with sheep manure as the main base material + 4 parts by weight of plant organic fertilizer produced with plant decay as the base material + 1 part by weight of humic acid (including humic acid).

[0018] Furthermore, the physical and chemical property parameters of the plateau rhizobium + soil active bacteria mixture include: a concentration of not less than 1 billion cfu / ml.

[0019] In a second aspect, the present invention provides a method for preparing the plateau soil remediation material according to any one of the first aspects, the preparation method comprising the following steps:
