Organic cultivation medium produced from chicken manure residues and sludge compost and production method of organic cultivation medium

Abstract

The invention relates to an organic cultivation medium produced from chicken manure residues and sludge compost and a production method of the organic cultivation medium. The production method of the organic cultivation medium comprises the steps of material preparation, heap building for fermentation, crushing and mixing. The organic cultivation medium takes the chicken manure residues and the sludge compost as main raw materials, wherein the chicken manure residues are solid chicken manure residues obtained by separating flushing sewage of a large-scale chicken farm through a solid-liquid separator; and the sludge compost is obtained by mixing urban living sludge and edible fungi residue cultivation waste residues and carrying out fermentation for thorough decomposition. According to the organic cultivation medium, the materials are convenient to obtain, the cost is low, and the produced organic cultivation medium has excellent physical and chemical properties including low salinity, high organic content, moderate nutrients and the like, and can meet requirements for solid medium cultivation of crops so as to realize the resource utilization of wastes.

Description

technical field [0001] The invention relates to a solid cultivation substrate and a production method thereof, in particular to an organic cultivation substrate produced by composting chicken dung and sludge and a production method thereof. Background technique [0002] With the rapid development of protected horticulture, soilless culture technology and plug seedling technology are being popularized and applied in a large area and on a large scale, which greatly promotes the research, development and application of solid cultivation substrates. In soilless cultivation, compared with hydroponics, solid substrate cultivation facilities are simple, low investment cost, and are widely used. my country is the largest protected horticultural country in the world, with a protected horticultural cultivation area of ​​2 million hm 2 Above, but according to incomplete statistics, the national soilless cultivation area is only 1070hm 2 , The proportion is very low, while the area of...

Problems solved by technology

At present, peat and rock wool are commonly used substrates, but the excavation of natural peat soil poses a serious threat to the ecological environment of wetlands and forests, causing damage to the ecosystem; rock wool is not degradable, and long-term use will cause serious environmental damage. Pollution, and my country's domestic rock wool is generally not suitable for soilless seedlings, and the cost of imported rock wool is too high. Therefore, countries all over the world are looking for alternatives to peat and rock wool

In recent years, people have used agricultural organic waste as a seedling substrate, such as poultry manure, sawdust, coconut shell fiber, etc., but the seeds caused by poor chemical stability, high salinity, low organic matter, poor cation exchange capacity, and high pollutant content Problems such as low germination rate, slow germination speed, weak seedlings, and burning seedlings affect its use as a seedling substrate
