Method for producing pyroclastic rock compressed nutrient soil

Abstract

The invention discloses a method for producing pyroclastic rock compressed nutrient soil. According to the technical scheme, the method is characterized by comprising the following steps: acidizing pyroclastic rock and sludge, performing stirring, compression and microwave low-temperature sterilization on ingredients of the pyroclastic rock compressed nutrient soil, and packaging to obtain a finished product. The pyroclastic rock compressed nutrient soil is prepared from acidized pyroclastic rock, acidized sludge, polyvinyl alcohol, ferrous sulfate, peat, flower ceramsite, high-viscosity attapulgite clay, biogas slurry, crushed plant fibers, expanded vermiculite, expanded perlite, super absorbent resin and other materials, contains massive nitrogen, phosphorous, potassium, organic matters and multiple trace elements, can provide nutritional elements necessary to plant growth and reduce hurts of pathogenic bacteria and insects on plants, is advantageous to normal growth and development of plants, and can protect the ecological environment. The method for producing pyroclastic rock compressed nutrient soil is applicable to production of pyroclastic rock compressed nutrient soil with different formulas.

Description

technical field [0001] The invention relates to nutrient soil, in particular to a production method of pyroclastic rock compressed nutrient soil. Background technique [0002] Pyroclastic rocks coexist with attapulgite clay deposits. Pyroclastic rocks are mostly in the upper layer of attapulgite clay deposits. In some attapulgite clay deposits, the thickness of pyroclastic rock layers in the upper layer is as high as tens of meters. During the mining of attapulgite clay, pyroclastic rocks in the upper layer of the attapulgite clay mining area are discarded as waste. According to field investigations, more than 30 tons of pyroclastic rocks are produced for every ton of attapulgite clay mined. Calculated at an annual output of 150,000 tons, the generated pyroclastic rocks are as high as 4.5 million tons, which have not been utilized for many years. The entire mining area is full of re-accumulated pyroclastic rock mixtures, causing serious waste of resources and economic losses...

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

[0008] 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
