Manufacturing method of non-ground stereo greening organic composite substrate

Abstract

The invention discloses a manufacturing method of a non-ground stereo greening organic composite substrate, and belongs to the technical field of gardening. The substrate is composed of the following components in parts by weight: 2 to 3 parts of peat, 2 to 3 parts of husk coal slag, 3 to 5 parts of potato residues and agricultural waste mixed material fermented particles, 1 to 2 parts of coco coir silk, and a little amount of composite fertilizer, which is added to increase the nutrients. The manufacturing method comprises the following steps: drying agricultural wastes in the sun, grinding agricultural wastes into silks with a diameter not more than 2 mm and a length not more than 25 mm or particles with a particle size not more than 5 mm; then mixing the processed agricultural wastes with potato residues, adding a high temperature aging inoculant containing beneficial microbes, carrying out composting, aging, and fermentation so as to obtain particles of potato residues and agricultural waste mixed material; preparing bio-synthesized peat and husk coal slag; then adding coco coir silk and composite fertilizer, fully stirring and evenly mixing the raw materials and auxiliary materials together, loading the mixture into bags, weighing the bags, and storing the bags in a warehouse. The produced organic composite substrate has the advantages of fluffy texture, light weight, and rich nutrients, and is very suitable for the non-ground stereo greening such as arterial street guard bars, skyways, and the like.

Description

technical field [0001] The invention relates to a method for manufacturing a horticultural substrate, in particular to a method for manufacturing a non-ground three-dimensional greening organic composite substrate, which belongs to the field of soilless cultivation horticultural substrates. Background technique [0002] Greening is an essential and important engineering project for urban roads, residential areas, institutions, enterprises, schools, etc. Most of them are planted on the ground, also known as ground greening, but some buildings, structures, urban main roads, highway guardrails, and overpasses Greening is also required on vertical surfaces, roof surfaces, walls, building balconies, overpasses, ramps, and other spatial structures. These greenings are called non-ground greening or three-dimensional greening, vertical greening, which corresponds to ground plane greening and is in three-dimensional space. Use various site conditions and facilities above the ground t...

Problems solved by technology

The cost of growth substrate in non-ground greening accounts for 20-30% of the total cost. In the past, peat charcoal was generally used or imported directly from abroad, but the price is very expensive and the cost is high. Therefore, improving the performance of the substrate and reducing the cost of the substrate are the main research and development in aerial greening. Direction of development

[0005] On April 1, 2015, CN104478591A disclosed the applicant's "a kind of method for aerial greening light-duty substrate". It is composed of plant ash, peat and perlite, but peat is a non-renewable resource, the acidity of vinegar residue is low, the EC value is high, and the treatment is difficult. On the basis of the original substrate, this application uses artificial biosynthetic peat to replace natural peat, and rice husk residue Substituting plant ash, the physical and chemical properties and nutrients of the matrix are significantly better than the original matrix, and the production cost is also greatly reduced. Document retrieval found that artificial biosynthetic peat, chaff charcoal residue, potato grains and agricultural waste mixture are used as the main raw materials. The non-ground three-dimensional greening organic composite substrate and its production method using coconut bran shreds as auxiliary raw materials have not yet been reported in China.
