Low-carbon, environment-friendly and efficient organic vegetable culture medium and preparation method thereof

Abstract

The invention discloses a low-carbon, environment-friendly and efficient organic vegetable culture medium (organic nutrition packet) and a preparation method thereof. The culture medium comprises components in percentage by volume as follows: 15% to 20% of processing organic waste, 20% to 30% of inorganic mineral powder, 20% to 30% of an edible fungus waste residue, 25% to 35% of fresh dung or 80% to 90% of earthworm culture waste formed by the four materials, 5% to 10% of a poultry product organic fertilizer and 5% to 15% of processing high-nutrient organic waste. The preparation method comprises performing biological compost, cultivating a grass rotting edible fungus, cultivating an earthworm and adding a high-nutrient organic matter and the poultry product organic fertilizer in earthworm cast through fermentation treatment to form the low-carbon, environment-friendly and efficient organic vegetable culture medium. According to the low-carbon, environment-friendly and efficient organic vegetable culture medium and the preparation method thereof, a fermentation organism and the earthworm serve as main organisms to prepare the organic culture medium; and the low-carbon, environment-friendly and efficient organic vegetable culture medium and the preparation method thereof have the advantages that water and a fertilizer are retained, the nutrition is comprehensive, and nutrition needed by vegetable growth can be stably and abundantly provided, besides, the manufacture process is low-carbon, environment-friendly, efficient, low in cost and the like.

Description

technical field [0001] The invention relates to a vegetable planting substrate, in particular to a low-carbon, environment-friendly, high-efficiency organic vegetable cultivation substrate (also known as an organic nutrition package) and a preparation method thereof. Background technique [0002] Conventional cultivation substrates (also known as nutrient soil) mainly use inorganic substances (such as soil, cinder, fertilizer, vermiculite, zeolite powder, etc.) and organic substances (such as livestock manure, plant straw, mushroom residue, sawdust, organic fertilizer, peat soil, Weathered cinders, etc.) as raw materials, the conventional preparation method is to add fermented microbial agents, in a suitable environment, through its own heat-generating fermentation and decomposing, and sometimes requires external high temperature to kill germs and insect eggs; after fermentation or high temperature treatment , mix the organic and inorganic parts in a certain proportion to fo...

Problems solved by technology

[0002] Conventional cultivation substrates (also known as nutrient soil) mainly use inorganic substances (such as soil, cinder, fertilizer, vermiculite, zeolite powder, etc.) and organic substances (such as livestock manure, plant straw, mushroom residue, sawdust, organic fertilizer, peat soil, Weathered cinders, etc.) as raw materials, the conventional preparation method is to add fermented microbial agents, in a suitable environment, through its own heat-generating fermentation and decomposing, and sometimes requires external high temperature to kill germs and insect eggs; after fermentation or high temperature treatment , mix the organic and inorganic parts in a certain proportion to form a relatively stable and buffering full-nutrient cultivation substrate raw material; the organic cultivation substrate, also known as nutrient soil, has the disadvantages of high price and low Unbalanced nutrient supply and prone to problems such as diseases, insect pests and weeds, there is no product that can be popularized in production

At present, the industrial cultivation of vegetables is mainly carried out by nutrient solution or organic-inorganic solid substrate with nutrient solution for cultivation and production. There are problems such as huge investment, low quality of cultivated products but high price, and it is difficult to popularize and apply on a large scale, let alone satisfy people's expectations. Growing demand for safe, high-quality and environmentally friendly vegetable products

In the prior art, the nutrients contained in the substrate or nutrient soil for vegetable cultivation often cannot meet the needs of vegetable growth. To ensure the yield, it is necessary to use chemical fertilizers to supplement

Most of the vegetables cultivated with chemical fertilizers are prone to problems such as not fresh enough, poor taste and short shelf life, and do not meet the requirements of organic food production
