Organic cultivation substrate produced by utilizing cattle manure residue and sludge compost and production method thereof

Abstract

The invention relates to an organic cultivation substrate produced by utilizing cattle manure residue and sludge compost and a production method thereof. The organic cultivation substrate comprises the following raw materials in parts by weight: 80-85 parts of cattle manure residue and 15-20 parts of sludge compost, wherein the cattle manure residue is solid cattle manure residue which is obtained after performing solid-liquid separation on flushing sewage of a scaled cattle farm, the sludge compost is the sludge compost after mixing, fermentation and composting of urban domestic sludge and waste bacterial slag, the cattle manure residue and the sludge compost are uniformly mixed according to a proportion and then composted for performing aerobic fermentation, 50% of fermented material after the end of fermentation for crushing, and then the large-particle fermented material is uniformly mixed with the small-particle fermented material according to the weight ratio of 1.3: 1-1.2. The organic cultivation substrate disclosed by the invention can overcome the problems of damages to an environment, poor stability of chemical properties, high salt content, low content of organic matters, poor cation exchange capacity and influence on seedling raising of an existing soilless cultivation substrate, has the advantages of low content of salt, appropriate nutrients, low content of heavy metals and no damages to the environment, and can meet the requirements of organic cultivation.

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 cow 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 ​​...
