Silicon-based biological type acid soil modifier and preparation method thereof

Abstract

The invention relates to a silicon-based biological type acid soil modifier preparation method, a silicon-based biological type acid soil modifier comprises the following raw materials and components by weight: 500-800 parts of bone glue residues leftovers, 100-200 parts of powder instant potassium silicate, 50-100 parts of rice husk powder, 50-100 parts of beneficial bacteria masterbatch, 20-50 parts of magnesium carbonate, 10-50 parts of zinc nitrate and 5-20 parts of borax. The method is as follow: 1, proportionally mixing the bone glue residues leftovers and the rice husk powder, killing bacteria and spawn at high temperature; 2, meanwhile adding the magnesium carbonate and beneficial bacteria masterbatch, stirring evenly, fermenting at normal temperature in summer for 15-20 days, and drying in air; or fermenting in a fermentation tank in winter for 30-50 days, and drying in air; and 3, crushing the material dried in the step 2 to 80-100 mesh, proportionally adding the powder instant potassium silicate, the zinc nitrate and the borax, and adjusting the pH value to 7.5-8.5. Most of the materials used in the silicon-based biological type acid soil modifier are alkaline, and contain rich organic calcium, phosphorus, magnesium, boron, silicon, zinc and other elements.

Description

technical field [0001] The invention belongs to the field of soil improvers, and in particular relates to a method for producing a silicon-based biological acid soil improver by using bone glue leftovers. Background technique [0002] Acidic soil refers to soil with a pH value below 7, including brick red soil, red soil, red soil, yellow soil and dry red soil. In addition to the obstacles to plant growth and development caused by the H+ in the soil, this kind of soil is also accompanied by obstacles such as aluminum toxicity, manganese toxicity under flooding conditions, loss and reduced availability of plant nutrients, especially the lack of trace elements. [0003] Soil acidification is one of the main problems restricting the sustainable development of agriculture in my country. The problem of soil acidification in my country is very serious. The area of ​​various acidified soils is about 200 million hm 2 . In recent years, with the development of industry, the continuo...

Problems solved by technology

Although the former has a strong neutralizing function, if it is applied excessively or unevenly, it will cause local calcification, damage soil microorganisms, affect soil structure and cannot meet the needs of crops for medium and trace element fertilizers at the same time; the latter has insufficient neutralizing function Although it can supply medium and trace elements at the same time, there are often heavy metals and impurities harmful to soil fertility. A single type of medium and trace elements affects the balance of soil nutrients
