Production method of loess compressed nutrient soil

Abstract

The invention discloses a production method of loess compressed nutritional soil. According to the technical scheme, the production method comprises the following steps: acidizing loess and sludge; stirring ingredients of the loess compressed nutritional soil, compressing, sterilizing by microwaves at a low temperature, and packaging to obtain the finished loess compressed nutritional soil. The loess compressed nutritional soil comprises acidized loess, acidized sludge, instant sodium silicate, polyvinyl alcohol, ferrous sulfate, peat, flower ceramsite, high-viscosity attapulgite clay, biogas slurry, biogas residues, ground plant fibers, expanded vermiculite, expanded perlite and high-water-absorption resin. The loess compressed nutritional soil contains a large quantity of nitrogen, phosphorus, potassium, organic matters and various microelements, can provide nutritional elements necessary for plant growth, can reduce the damages of pathogenic bacteria and pests to plants, is beneficial to the normal growth and development of plants, can protect the ecological environment, and can avoid the secondary pollution to a surrounding environment, and the production method is suitable for producing the loess compressed nutritional soil according to different formulae.

Description

technical field [0001] The invention relates to acidification treatment, in particular to a production method of loess compressed nutrient soil. Background technique [0002] Loess is a special soil formed under arid climate conditions. It is generally light yellow, grayish yellow or yellowish brown, with large pores and vertical joints visible to the eye. Now it is generally believed that it is mainly deposited by wind, often calcareous and often contains Shells, bones, mammalian teeth, and calcium carbonate nodules, sometimes containing iron oxide nodules, form high-quality soil that can store a large amount of water; loess contains a lot of carbonate minerals, mainly calcite. Clay minerals are mainly illite, montmorillonite, kaolinite, goethite, hydrous hematite and so on. [0003] Loess is a very fertile soil layer, which is extremely important to agricultural production, but the vegetation is scarce, and soil erosion has caused serious harm to agricultural production a...

Problems solved by technology

Generally, it is prepared by mixing fertile field soil and decomposed manure. There are also nutrient soils selected from imported high-quality peat and coconut bran mixed in a specific proportion. However, these nutrient soils have not undergone reasonable ingredients and strict disinfection. Conducive to the normal growth and development of seedlings

[0009] Because the treated nutrient soil is relatively light and loose, the conventional product of nutrient soil is relatively large, which is not conducive to reducing the cost of production and transportation
