Description
Technical field
The present invention relates to a kind of agricultural fertilizer, particularly a kind of method utilizing beneficial microorganism fermented liquid to prepare liquid fertilizer.
Background technology
Liquid fertilizer is the one of water soluble fertilizer.Abroad to the research comparatively morning of water soluble fertilizer.Nineteen twenty-five, Britain discloses one is directly made water soluble fertilizer patent of the solid material of various blending.Nineteen sixty-five, the U.S. discloses the production patent of a sheet water soluble fertilizer.1988, U.S. TVA applied for the production patent that the suspension of high concentration N sulphur is fertile, utilized the low molten acquisition high content nitrogen altogether of ammonium nitrate, urea.1999, the U.S. disclosed the patent adopting extruder grain technology to produce particle water soluble fertilizer product, in granulated product, introduce dissolution aids.Abroad, water soluble fertilizer has been widely used in vegetables, flowers, fruit tree and field crop at present, also has the maintenance etc. of Garden Plant Landscape greening, golf course.The water soluble fertilizer product of present offshore company is all quite ripe, as Spain Ai Dela (Adler) company, Kang Piao (COMPO) company of Germany, Norway's Hydro (Hydro) company, chemical mining industry (SQM) company of Chile, U.S. Shi Ke get (Scotts) company, Haifa, Israel (Haifa) company, plant prod (Plant-prod) companies of Canada etc., wherein a lot of brand enters China.
China's water soluble fertilizer is started in the middle and later periods eighties 20th century.1996, Kemira Co., Ltd applied for " the suspension liquid fertilizer of phosphorous acid group and calcium or magnesium " patent in China, adopted suspension agents such as adding attapulgite to form the suspension liquid fertilizer of high density.1999, the patent of fertilizer for spray or drip irrigation and production method thereof was applied at Xinjiang Academy of Land Reclamation &. Cultivation's agricultural machinery popularization center, and product pH value is 4.4 ~ 6.0, good water solubility.Calendar year 2001, the patent of high-concentration multi-element liquid fertilizer and preparation method thereof has been applied in Inst. of Soil & Fertilizer, Shandong Prov. Academy of Agricultural Sciences, and for vegetables, fruit tree, product nutrient content is complete, and saline-alkali tolerance is strong, and cost is low.2002, Chinese Academy of Sciences's Graduate School of Engineering application drip irrigation acid liquid fertilizer patent, for In The Soil of Xinjiang, not clogging drip irrigation facility.2007 start, China Water soluble fertilizers industry develops rapidly, ends in July, 2011, puts on record in the Ministry of Agriculture and produce the producer of water soluble fertilizer and have nearly 300 in the whole nation, all kinds of water soluble fertilizer products of registration reach more than 4300, and national water soluble fertilizer output reaches 600,000-80 ten thousand tons.Now, domesticly many outstanding water soluble fertilizer production companies are emerged.The new stage that " 13 " period will be water soluble fertilizer fast development and leading market.
At present, China's water soluble fertilizer industry is still in the starting stage, and be embodied in: production technology is backwardness relatively, Mechanization Level is low, and technical study and production, the market requirement disconnect, and production technique is simple, and formula is formulated random large, and product technology content is lower.Overwhelming majority solid phase prod still takes the simple blending of several straight fertilizer, and what adopt chemical synthesis process to produce is little; Mostly most part liquid product is the little of simple liquid miscible employing chelating explained hereafter; Between the hardening of solid product, element, antagonism fixes phenomenon etc., and the chromatography phenomenon etc. of liquid product, happens occasionally.And " utilizing beneficial microorganism fermented liquid special efficacy to take array of biochemical chelating explained hereafter liquid fertilizer " has no report.
Gamma-polyglutamic acid-(poly-gamma-glutamic acid, English poly-γ-glutamicacid, be called for short PGA) be the water-soluble polyamino acid that occurring in nature fermentable produces, its structure is that glutamic acid units forms the high molecular polymer of peptide bond by alpha-amino group and γ-carboxyl.Molecular weight distribution is between 100kDa to 10000kDa.Poly-gamma-glutamic acid has excellent water-soluble, superpower adsorptivity and biodegradability; degraded product is non-harmful L-glutamic acid; it is a kind of excellent environment-friendly type macromolecule material; can be used as water-holding agent, adsorbent for heavy metal, flocculation agent, sustained release dosage and pharmaceutical carrier etc., all have very large commercial value and social value in industries such as makeup, environment protection, food, medicine, agricultural, desertification control.So far only have the history of decades from the discovery of polyglutamic acid, research and apply is still in the starting stage.Be applied to agriculture production, can play drought resisting, water conservation, enrichment nutrient, improve utilization rate of fertilizer, improve soil physical and chemical property, hestening rooting, raising crop quality, volume increase good harvest effect.Agriculturally the more mainly fertilizer plant of application at present uses as water-holding agent as fertilizer synergist and west droughty area, successful.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of method utilizing beneficial microorganism fermented liquid to prepare liquid fertilizer.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of method utilizing beneficial microorganism fermented liquid to prepare liquid fertilizer, comprises the steps:
Step one, be combined with beneficial microorganism zymotechnique, after beneficial microorganism has fermented, fermentor tank be warming up to 80 DEG C and carry out high-temperature inactivation, obtain beneficial microorganism fermented liquid;
