Abstract
The invention discloses a water-retention microbial fertilizer which is prepared from the following raw materials (by weight): 50-52 parts of fungus chaff, 10-11 parts of rice bran, 5-6 parts of old tea leaf, 6-7 parts of zeolite, 4-5 parts of soybean meal, 1-2 parts of konjac glucomannan, 25-30 parts of attapulgite, 5-5.5 parts of azotobacter chroococcum, 70-72 parts of a phosphate buffer at pH7.0, 5-6 parts of sodium alginate, 4-5 parts of calcium chloride and 2-3 parts of chitosan. According to the application, fungus chaff is used as a microbial carrier, and more organic matters are provided for growth of strains. After fungus chaff is puffed, water absorption of the microbial fertilizer is raised, and a moist living environment is provided for microbes. By embedding of sodium alginate, salt tolerance, acid-base resistance, cold and heat resistance and drug resistance of microbes can be enhanced. By coating with chitosan, low mechanical strength of sodium alginate is overcome. In addition, konjac glucomannan added can have an effect of water retention.
Description
Technical field
The present invention relates to technical field of fertilizers, particularly relate to a kind of water conservation microbial fertilizer and preparation method thereof.
Background technology
Along with the develop rapidly of world economy, the consumption of the mineral fuel such as oil grows with each passing day, and the energy dilemma extreme shock caused thus fertilizer industry, and a large amount of production of chemical fertilizer and use harm ecotope balance and human health.And microbial fertilizer has high, the reproducible feature of fertilizer efficiency, the ecological agriculture advocated with modern agriculture, Organic farming are coincide.Microbial fertilizer carrier in the market has vermiculite, perlite, peat and fertilizer etc. that some become thoroughly decomposed, wherein using peat as generally.And peat is under special Marsh Wetland environment, plant residue through complicated and slowly biochemical action, to build up and ulmification is formed.It is non-renewable that it has short-term as the natural Mineral resources of one.Bacterium chaff is the residue waste material after Edible Fungi, and the traditional method of process bacterium chaff abandons or burns, and not only causes the wasting of resources, cause mould and pest infestation simultaneously, thus cause environmental pollution.Therefore, how effectively to utilize edible fungus bran, grown fat as treasured, become problem demanding prompt solution.
Summary of the invention
The object of the invention is exactly the defect in order to make up prior art, provides a kind of water conservation microbial fertilizer and preparation method thereof.
The present invention is achieved by the following technical solutions:
A kind of water conservation microbial fertilizer, be made up of the raw material of following weight part:
The phosphate buffered saline buffer 70-72 of bacterium chaff 50-52, rice bran 10-11, old tea 5-6, zeolite 6-7, soyflour 4-5, Rhizoma amorphophalli glucomannan 1-2, attapulgite 25-30, azotobacter chroococcum 5-5.5, pH7.0, sodium alginate 5-6, calcium chloride 4-5, chitosan 2-3.
The preparation method of described water conservation microbial fertilizer, comprises the following steps:
(1) by expanded for bacterium chaff twin-screw extruder rear cooling crush, crossing aperture is the sieve of 0.25mm, continuous sterilization 1 hour at 121 DEG C, dries;
(2) phosphate buffered saline buffer of pH7.0 and step (1) gained material are mixed, access azotobacter chroococcum, cultivates 7 days in the constant temperature biochemical cultivation case at 28 DEG C;
(3) calcium chloride is added sterile distilled water and be configured to the solution that concentration is 4%, obtain calcium chloride solution; Sodium alginate is added sterile distilled water heating for dissolving, be configured to the solution that concentration is 2%, to be cooled to adding step (2) gained material when 40 DEG C, abundant mixing, is then dropwise added dropwise in calcium chloride solution, leaves standstill crosslinked 1-1.5 hour, with 0.3mol/L glutaraldehyde solution process 1-1.5 hour, wash with the sodium chloride solution of 0.9% again, then solidify 24 hours at 4 DEG C, for subsequent use;
(4) chitosan is added water be mixed with the chitosan solution that concentration is 0.3%, then the coating process in chitosan solution of step (3) gained material was taken out after 0.5 hour;
(5) rice bran, old tea, zeolite are pulverized, then mix with step (4) gained material and leftover materials, add water and make material moisture reach 20%, granulation, to obtain final product.
Advantage of the present invention is: the application adopts bacterium chaff as microbe carrier, higher compared to its organic content of conventional carriers peat, can be growth and more organicly provide, and bacterium chaff is through expanded, structure organization is loosened, improve water-absorbent, moistening living environment can be provided for microorganism attached thereto, and when cultivating, add phosphate buffered saline buffer maintenance neutrality, sodium alginate is adopted to embed, the salt tolerance of microorganism can be improved, resistance to acids and bases, cold-resistant hot and resistance, again with chitosan coated, overcome the weakness that sodium alginate physical strength is little, in addition, the Rhizoma amorphophalli glucomannan that the present invention adds can play the effect of water conservation.
