Problems solved by technology

Not only reduces the yield and quality of crops, but also indirectly endangers human health
[0003] The control of soil pollution is mainly through engineering restoration methods and phytoremediation methods, of which engineering restoration methods mainly include soil improvement methods, electric restoration, soil leaching and heat treatment methods, etc. Engineering treatment measures are usually suitable for small polluted areas and serious pollutants. And the effect of the soil that is easy to spread is more obvious, which can fundamentally improve the soil, but the cost of treatment is high, and it is easy to form secondary pollution, and may damage the soil structure, whi

Embodiment Construction

[0020] A manganese ore contaminated soil repair fertilizer is made from the following raw materials in parts by weight (kg): peat soil 7, plant ash 31, beer dregs 15, chicken feathers 22, chitosan oligosaccharide 4, iron humate 3, calcium sulfate 2, Palm leaf 30, siderite slag 14, limonite slag 14, orange peel 65, EM compound microbial agent 4, appropriate amount of water.

[0021] The concrete steps of the preparation of described soil restoration fertilizer are as follows:

[0022] (1) Dry orange peel and palm leaves in the air and mix them with siderite slag, place them in a closed calciner, heat up to 420°C at a rate of 15°C / min under a nitrogen atmosphere, and add limonite after 20 minutes of heat preservation slag, keeping the temperature for 30 minutes, then lowering the temperature to 240°C, continuously feeding oxygen into the closed calciner, taking out the calcined product after 30 minutes, shaking and shaking for 15 minutes and passing through a 20-mesh sieve to ob...

Abstract

The invention discloses fertilizer for repairing soil polluted by manganese ore. The fertilizer is prepared from, by weight, 7-8 parts of peat soil, 31-33 parts of plant ash, 15-16 parts of beer residues, 22-25 parts of chicken feather, 4-6 parts of chitosan, 3-4 parts of humic acid iron, 2-3 parts of calcium sulfate, 30-32 parts of palm leaves, 14-16 parts of siderite slag, 14-16 parts of limonite slag, 65-70 parts of orange peel, 4-6 parts of EM compound microorganism bacterium agent and an appropriate amount of water. For the characteristics that soil polluted by manganese ore is low in fertility, poor in water-retaining property and high in heavy metal content, through the collaborative complexing and degrading effects of biochar immobilized microorganisms and lots of humus, on one hand, the water permeation speed is decreased, the water-retaining potential of soil is increased and the water-retaining property is enhanced by increasing the porosity of soil, and on the other hand, the content of organic carbon and humus in soil is increased and the fertilizer retention capacity is improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a manganese ore polluted soil repair fertilizer. Background technique [0002] With the rapid development of the economy and the advancement of industrial technology, the adverse impacts of industrial and agricultural production on the environment have been increasing. Due to the continuous accumulation and dumping of solid waste on the soil surface, harmful waste water has continuously penetrated into the soil, harmful gases and dust in the atmosphere It also continues to fall into the soil with rainwater, causing soil pollution. It not only reduces the yield and quality of crops, but also indirectly endangers human health. [0003] The control of soil pollution is mainly through engineering restoration methods and phytoremediation methods, of which engineering restoration methods mainly include soil improvement methods, electric restoration, soil leaching and heat treatmen...
