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

Embodiment Construction

[0060] Below in conjunction with embodiment the present invention will be further described:

[0061] 1. The production method of illite compressed nutrient soil: (1) Input the ingredients of illite compressed nutrient soil into the running mixer for stirring, and after stirring evenly, input it into the tablet press to compress into illite compressed nutrient soil flakes, and illite compressed nutrient soil The thickness of the soil flakes is controlled at 20 mm; (2) The illite compressed nutrient soil flakes are transported to a microwave belt drying and sterilizing machine for low-temperature sterilization and drying, the temperature is controlled at 70-90 °C, and the time is controlled at 40 minutes, the moisture content of the sterilized and dried illite compressed nutrient soil flakes is less than or equal to 13%; (3) the sterilized and dried illite compressed nutrient soil flakes are transported to the thermal insulation sterilizer, and the illite The residual heat in t...

Abstract

The invention discloses a production method for compressed illite nutrient soil. The technical scheme is characterized by firstly carrying out acid treatment on illite and sludge; and then packaging to obtain finished products after stirring, compressing and carrying out micro-wave sterilization on ingredients of the compressed illite sludge nutrient soil at a low temperature. The compressed illite nutrient soil consists of materials such as acidified illite, acidified sludge, sodium silicate hydrate, polyvinyl alcohol, ferrous sulfate, peat, flower ceramsite, high-viscosity attapulgite clay, biogas slurry, crushed plant fiber, expanded vermiculite, expanded perlite and super absorbent resin. The compressed illite nutrient soil contains a great deal of nitrogen, phosphor, potassium, organic matters and various trace elements, can provide nutrient elements needed for plant growth, can reduce harm of pathogenic bacteria and pests on plants, is beneficial to normal growth and development of plants and protects ecological environment, and the production method for the compressed illite nutrient soil is applicable to producing the compressed illite nutrient soil with different formulas.

Description

technical field [0001] The invention relates to nutrient soil, in particular to a production method of illite compressed nutrient soil. Background technique [0002] Illite is a common clay mineral, often formed by weathering of muscovite and potassium feldspar, and produced in argillaceous rocks, or formed by alteration of other minerals. It is often an intermediate transitional mineral that forms other clay minerals. Pure illite clay is white, but it is often dyed yellow, green, brown and other colors due to impurities, and it is gray or black soil with more impurities, brittle, brittle, fine texture, smooth, low hardness, long-lasting It does not swell and loosen in water with turbidity. [0003] Sludge is a kind of easily corrupt and smelly paste produced in the process of sewage treatment. It enriches the pollutants in sewage, contains a large amount of nutrients such as nitrogen and phosphorus, organic matter, virus microorganisms, parasite eggs, heavy metals, etc. ...
