Production method of attapulgite compressed nutrient soil

Abstract

The invention discloses a production method of attapulgite compressed nutrient soil. The point of the technical scheme is that the method comprises the following steps: acidifying attapulgite; and performing stirring, compression and microwave low-temperature sterilization of the ingredients of the attapulgite compressed nutrient soil, and packaging into a finished product. The attapulgite compressed nutrient soil consists of acidified attapulgite clay, instant sodium silicate, polyvinyl alcohol, ferrous sulfate, peat, flower ceramsite, high-viscosity attapulgite clay, biogas slurry, biogas residue, plant fiber, expanded vermiculite, expanded perlite, super absorbent resin and other materials. The attapulgite compressed nutrient soil contains a great quantity of nitrogen, phosphorus, potassium, organic matters and multiple trace elements and can provide necessary nutrient elements for the plant growth to reduce the harm to plants caused by pathogenic bacteria and pests, facilitate normal growth and development of the plants, protect the ecological environment and avoid secondary pollution to the surrounding environment; and the production method of the attapulgite compressed nutrient soil is suitable for producing compressed nutrient soil of different formulas.

Description

technical field [0001] The invention relates to nutrient soil, in particular to a production method of attapulgite compressed nutrient soil. Background technique [0002] Attapulgite has unique dispersion, high temperature resistance, salt and alkali resistance, good colloidal properties and high adsorption capacity, and has certain plasticity and cohesive force. [0003] Nutrient soil is a soil specially formulated to meet the growth and development of seedlings, containing a variety of mineral nutrients, loose and ventilated, strong in water and fertilizer retention, and free of pests and diseases. Generally, it is prepared by mixing fertile field soil and decomposed manure. There are also nutrient soils that are selected from imported high-quality peat and coconut bran and mixed in specific proportions. However, these nutrient soils have not undergone reasonable ingredients and strict disinfection and sterilization. It is not conducive to the normal growth and developmen...

Problems solved by technology

[0006] The disadvantage of the above-mentioned patents is that the "compressed plant cultivation substrate" simply mixes the ingredients and presses them into blocks. After the selected woody nutrients are pressed into blocks, it is difficult to provide nutrients for the cultivated plants in a short time. ; The relevant standards stipulate that the content of organic fertilizer is ≥ 5%, and the above-mentioned patent "the content of organic fertilizer is preferably 20-25" is impossible to achieve; attapulgite is ordinary attapulgite that has not been modified, and ordinary attapulgite The soil has poor viscosity and cannot act as a binder. It is just a kind of filler. The effect of anti-scouring and water retention and drought resistance is not good. It can only be used for plant seedling cultivation and is not suitable for roof greening.
