Artificial soil and preparation method thereof

Abstract

The invention discloses artificial soil and a preparation method thereof. The method comprises the following steps: respectively weighing citric acid, copper sulfate powder, zinc sulfate powder, ferrous sulfate powder, manganese sulfate powder, ammonium molybdate powder and water according to weight ratio; mixing above materials, and stirring with the rotation speed of 100 turns / min for 30-40min under the reaction temperature of 80-90 DEG C to obtain trace element chelating solution for later use; respectively weighing oil shale waste, furfural dreg, crop straw, calcium carbonate, magnesium sulfate, urine, phosphate fertilizer, potash fertilizer and borax according to weight ratio; drying above raw materials and crashing, sieving by a sieve with 60-80 meshes, crushing crop straw into 1-3cm, pouring above raw materials into a stirrer, stirring while spraying trace element chelating solution accounting for 6-8% of the quality of the raw materials, evenly stirring to obtain the artificial soil. The invention has the advantages of low cost, good physical and chemical property and the like, and is applicable to plant growth.

Description

1. Technical field

[0001] The invention belongs to the technical field of artificial soil, and in particular relates to an artificial soil and a preparation method thereof. 2. Background technology

[0002] Oil shale is a kind of sedimentary rock containing organic matter. The proven resource in my country is 2.4 billion tons. With the increasing shortage of oil, natural gas and other resources in the world, the development and utilization of oil shale is expanding day by day, and a large amount of oil shale waste (including oil shale dust, oil shale lean ore, oil shale tailings or oil shale ash) discharged by the industry is piled up into mountains, occupying a large amount of land, seriously affecting ecosystem. Oil shale waste contains SiO 2 It is a good source of plant nutrients and soil conditioner, but it has not been well utilized for a long time, resulting in a waste of resources. 3.
