Abstract
The invention provides fermentation strains Brevibacterium sp D1 (with the perservation number of CCTCC No: M 2010250) and bacillus amyloliquefaciens S4 ( with the preservation number of CCTCC No: M 2010249) of a microbial organic fertilizer of tobacco straws; the fermentation strains Brevibacterium sp D1 and the bacillus amyloliquefaciens S4 are separated and screened from the tobacco straws under a high-temperature and heavy-nicotine condition, and can exist in the presence of the nicotine; and after being cultivated and proliferated, the ermentation strains Brevibacterium sp D1 and the bacillus amyloliquefaciens S4 are added into a waste tobacco straw mixture, and are subjected to solid fermentation under a natural condition to convert the tobacco straw wastes into the tobacco straw microbial organic fertilizer. The tobacco straw microbial organic fertilizer can replace other fertilizers to produce the tobacco, and has the advantages of increasing yield of the tobacco leaves, increasing production values of the tobacco leaves, improving smoking quality of the tobacco leaves, and simultaneously removing pollution to the environment by the tobacco straw wastes.
Description
Technical field
What the present invention relates to is agro-ecology organic fertilizer production technology, and particularly a kind of solid state fermentation prepares the process for preparing strain thereof of tabacco straw biological organic fertilizer.
Background technology
Tobacco is a kind of important cash crop, has a very important role in national economy.In China's tobacco planting production process, for a long time based on chemical fertilizer, cause soil organism quantity to fall sharply, the coacervate quality and quantity descends, and air permeability is degenerated, and influences output and the quality of leaf tobacco production.In addition, behind tobacco leaf picking, abandon a large amount of discarded tabacco straws in vega, maximum duration can reach five months, increases next year vega disease and pest, pollutes the vega ecotope.According to the industry regulation, should concentrate the tabacco straw burning disposal, but can increase CO like this
2Quantity discharged causes air environmental pollution.Be a kind of must not and for it way.
Use general agricultural crop straw solid-fermented technique in the prior art fermentation of tobacco straw is become the biological organic fertilizer method, but because tabacco straw contains a large amount of nicotine, has a large amount of harmful germs and viruses again, this method is not preferably selected microbial strains, and effect is bad.Fermenting bacteria commonly used is not suitable for surviving under the condition with a large amount of nicotine materials, and the conversion of can not effectively fermenting is so existing method is difficult to address the above problem.If can seek a kind of anti-strong nicotine high temperature microbe, have the fermenting bacteria that under the condition of a large amount of nicotine materials, survives, carry out solid state fermentation, discarded tabacco straw is changed into a kind of safe biological organic fertilizer, part instead of chemical composite fertilizer is backfilling into vega.Disease and pest, Soil degradation, environment protection, the utilization of resources and quality of tobacco problem in the tobacco production are considered in the lump, and be used.Be conducive to improve environment like this, widely.
Summary of the invention
The objective of the invention is to propose a kind of preparation method of the solid state fermentation bacterial classification that can under the heavy nicotine condition of high temperature, survive.With the solid state fermentation bacterial classification of the anti-nicotine of this heatproof through cultivate and expand numerous after, join in the discarded tabacco straw mixture, carry out solid state fermentation under field conditions (factors), the tabacco straw waste is converted into the tabacco straw biological organic fertilizer.
Concrete steps are:
1, strains separation screening: from the tabacco straw of the regional vega of difference, sampling joins glucose, the peptone that contains nicotine respectively, and yeast extract paste in the liquid nutrient medium of inorganic salt, under 50～60 ℃ of high temperature, was cultivated 48 hours.With the nutrient solution dilution, coat nicotine-containing peptone, in the agar culture dish of yeast extract paste, under 25～35 ℃, cultivated 24～36 hours.Picking list bacterium colony is inoculated into respectively and simultaneously in the liquid or solid substratum of same numbering of peptone, yeast extract paste, inorganic salt, under 30 ℃, cultivates 24～30 hours.Extract centrifugal supernatant nutrient solution, add Streptomycin sulphate, penicillin and carboxymethyl cellulose, under 50 ℃, be incubated 18 hours, measure reducing sugar content, separate S
