Technical field
The invention belongs to environmental protection technical field, relating to the probiotics that extracts in the producing fertilizer from refuse in daily life is raw material, preparation highly effective compost composite fungus agent.The preparation composite fungus agent say so more specifically strengthening the lawn plant photosynthetic capacity, promote the application of the synthetic aspect of chlorophyll.
Background technology
Composting (composting) is mikrobe (bacterium, actinomycetes, fungi etc.) or the commercial strain that utilizes nature extensively to exist; Controlledly promote biodegradable organism to stable soil ulmin (humicsubstance, the Biochemical processes that HS) transform.This process also is the part of earth surface ecological process, and it participates in the matter and energy circulation of earth surface.
Under artificial control condition, can the organism in the solid waste be transformed into organic fertilizer one compost (compost) through composting, this organic fertilizer is as the final product of composting, not only stable performance, and very little to the harm of environment.Therefore, composting is a solid waste, especially one of effective way of innoxious, stabilization of domestic waste and resource utilization.Composting development has been experienced very long history so far, and the historical process of its generation and development is looked back and analyzed, and can be to develop new composting process technology from now on reference and help in the theory and practice are provided.
Old generation and etc. (1989) adopt the rubbish substratum; In the producing fertilizer from refuse in daily life treating processes; When temperature reaches 45 ℃ and 55 ℃; The compost bacterial strain is separated, and find in the time of 45 ℃: aspergillus tubigensis [Aspergillus], bacillus [Bacillus], Pseudomonas [Pseudomonas] and Sporolactobacillus [Sporolactobacillus] etc. are the dominant microfloras in the compost.Then different during to 55 ℃; Except bacillus [Bacillus] and Pseudomonas [Pseudomonas] still are the dominant microflora; Lactobacillus genus [Lactobacillus], streptococcus [Streptococcus] and micromonospora [Micromonospora] belong to then becomes new dominant microflora; Substituted other kind mikrobe, be illustrated in the composting process, microbial population is among the running balance that constantly changes.
From domestic waste, isolate the mikrobe of a large amount of participation high temperature aerobic compostings, be respectively bacillus, Pseudomonas through identifying, lactobacillus genus, Staphylococcus, Escherichia etc. 5 belong to bacterium; Aspergillus, Mucor, monascus, penicillium, Geotrichum, mould genus, arteries and veins sporeling genus, Cephalosporiums etc. 8 belong to mould; Streptomyces 1 belongs to actinomycetes; Saccharomycodes, fission yeast bacterium etc. 2 belong to yeast.This result of study has effectively promoted research of mikrobe in the garbage compost and utilization.Hassen (2001) is to the biological investigation discovery that changes of city compost process Ei; The high temperature that decomposing organic matter produces causes the significant variations of microflora; Pathogenic bacterium, yeast and mesophilic bacteria are reduced in a large number; And sporiferous bacillus exists in a large number, and in composting process, hot stage initial stage and Chinese stage bacterium are all in the highest flight.Marvin's ripples etc. has also been reported thermophilic fungus, and thermophilic brown actinomycetes etc. are participated in the microbial population of garbage compost.
Organic composition from domestic waste, and decomposed utilization by Institute of Micro-biology.But various mikrobes are not quite similar to the resolving power and the decomposition rate of various materials, the microbial population that occurs in (middle temperature, high temperature) composting process under the differing temps and quantitatively also completely different.
