Biological organic matrix and preparation method thereof

Abstract

The invention provides a biological organic matrix. The biological organic matrix aims at overcoming the defects of the prior art. A preparation method of the biological organic matrix comprises the following steps that S1, straw, bacterium resides, pine needles, pig mature, cornstalk heap clay fertilizer, rape seed cakes, walnut shells and nicotine are prepared; S2, the straw, bacterium resides,pine needles, pig mature and cornstalk heap clay fertilizer are adjusted until the water content is 70-80%; S3, after the mixture obtained in S2 is mixed, water is added to the mixture, then the mixture is placed in a sealed fermentation pool for fermentation, and a fermentation mixture is obtained after fermentation is completed; S4, the fermentation mixture is taken, the rape seed cakes and walnut shells are added to the fermentation mixture and smashed, the mixture is evenly mixed, and an airing mixture is obtained under the natural condition; S5, after nicotine is added to the obtained airing mixture and the mixture is evenly mixed, and then a storage mixture is obtained through sealed storage; S6, the storage mixture is heated, sealed and bagged to obtain the biological organic matrix. The prepared biological organic matrix can be suitable for soilless cultivation of multiple kinds of plants, the pollution is reduced, and meanwhile the income of related manufacturers is increased.

Description

technical field [0001] The invention belongs to the technical field of organic substrates, and in particular relates to a bio-organic substrate and a preparation method thereof. Background technique [0002] Since the 1990s, my country's facility agriculture has developed rapidly, and now it has exceeded 2.6 million hectares, becoming a pillar industry in my country's rural areas. The rapid development of modern protected cultivation has made the accumulation of harmful organisms in the protected soil, the imbalance of nutrient elements, continuous cropping obstacles and secondary salinization of the soil increasingly prominent. The use of soilless cultivation technology is the most effective, economical and thorough way to overcome the obstacles of continuous cropping in greenhouses, so it has been vigorously developed in foreign advanced agricultural countries. Netherlands until 1994, in its 4000hm 2 More than 40% of greenhouse crops use matrix cultivation technology, an...

Problems solved by technology

An important factor restricting the development of soilless cultivation in my country is its high input cost, and the cost of substrate is also very high.

Existing organic matrices generally have high preparation costs, single product effects, and insufficient product porosity, which limits the large-scale application of organic matrices
