Description
Technical field
The present invention relates to a kind of micro organism composite fertilizer production technical field, particularly a kind of chloro γ-composite bio-fertilizer and preparation method thereof.
Background technology
Chemical fertilizer plays more and more important effect in modern agricultural production, and wherein composite fertilizer's Year's consumption is very large, about tens million of ton every year.Conventional composite fertilizer's kind, greatly to being divided into S-based compound fertilizer, nitro-compound fertilizer, chlorine-based compound fertilizer three types, being broken mutually in recent years and being developed all kinds of durable composite fertilizer new variety.Domestic Fertilizer Industry mainly with nitrogen, phosphorus, potassium for raw material, adopt the method for physics or chemosynthesis to be produced into element compound or composite fertilizer, the technique of producing NPK composite fertilizer mainly contains: the slurry-spraying drum granulator based on phosphoric acid, sulfuric acid and ammonia synthesis reaction; KHSO is changed into KCl and sulfuric acid low temperature
4after the slurry-spraying drum granulator that mixes with phosphoric acid again; Granulating method compound granulation process based on Nitrogen-and Phosphorus-containing potassium solid fertilizer; Tower-type melt granulation technique based on the solid fertilizers such as Nitrogen-and Phosphorus-containing potassium.
In conventional composite bio-fertilizer, the composite fertilizer of content more than 3% of chlorion is called chlorine-based compound fertilizer, because the growth of chlorine-based compound fertilizer material to some fear-chlorion crop exists negative impact, and chlorion concentrating in soil remains in a large number, easily causes soil compaction, salinization, alkalization.Worry that using Chloride fertilizer can produce detrimentally affect to crop yield and quality.Major part bio-fertilizer manufacturing enterprise is in fertilizer process, and potassium sulfate is selected in required potassium source, or sloughs the chlorion in Repone K, makes so-called S-based compound fertilizer.S-based compound fertilizer complicated process of preparation, production cost is high, and price is also higher, adds the production cost of agricultural-food.Chloro fertilizer is relative to sulfenyl fertilizer, and low cost of manufacture, selling price is also starkly lower than sulfenyl fertilizer.Reduce burden for increasing farmers' income will play a positive role, therefore developing high-quality chloro fertilizer is that people expected.
According to scientific experiment, chlorine is one of necessary seven kinds of trace elements of plant-growth, chlorine element can enter vegetable cell by the photosynthesis of involved in plant, play the osmotic pressure of regulating plant cell and the startup of pore and close, be conducive to the absorption of moisture and nutrient, improve its drought-resistant ability, chlorion has effect such as promotion photosynthesis and processbearing astrocyte etc., and it is particularly suitable to use fibre crops such as crudefiber crops; Improve the resistance against diseases of plant.Chlorion has restraining effect to the nitrobacteria in soil, can delay the conversion rate of ammonium nitrogen to nitric nitrogen, thus effectively reduces nitric nitrogen loss and denitrification loss, is that the fertilizer efficiency of nitrogenous fertilizer is lasting.Stabilizing ion in chlorine crop plants cell, has active effect to intracellular storage ionic equilibrium and to element absorption such as nitrogen, phosphorus, potassium, calcium, magnesium, is conducive to promoting that plant stem-leaf grows; Facts have proved that it is all useful and harmless for using chloro fertilizer, especially chlorion has effect such as promotion photosynthesis and processbearing astrocyte etc.
Although chloro bio-fertilizer low cost of manufacture, produce simple advantage, but the urea fertilizer utilization ratio in simple chloro fertilizer is but very low, the chlorine element in bio-feritlizer how is made to play a positive role in promotion crop growth, the nitrogenous fertilizer in urea can be made again fully effectively to be utilized, improve slowly-releasing usefulness and the permanent mechanism of chloro biological nitrogen fertilizer, thus play chlorine without element, the multiple positive effect of nitrogen element and bio-bacterial manure, associating promotion plant growth, improving edatope is the problem that people expect to research and develop, manufacture the expectation that the biological nitrogen fertilizer with same performance and effect is market and peasant.
Gamma-polyglutamic acid-(γ-poly-glutamic acid, be called for short γ-PGA) be the anionic polyamino acid that fermentable produces, environmentally safe, for green bio product, the biodegradability that tool is splendid, film-forming properties, become fibering, plasticity-, cohesiveness, the physics and chemistry of many uniquenesses such as moisture retention and biological characteristics, these characteristics make it have thickening, emulsification, gel, film forming, insulation, slowly-releasing, the beneficial functions such as hydrotropy and bonding, make it in agricultural, medicine, environment protection, food, the numerous areas such as makeup have very wide application prospect.
At China and even world wide, herbaceous plant is extended familys, and aboundresources is of a great variety; Wherein bromegrass, oat, barley are improved seeds wherein, fast growth, the solid granulates material extracted from wheat straw class leaf, there is abundant amino acid, SOD enzyme, trace element, mineral substance and a large amount of microorganism species, it is the synergistic substance that a class is excellent, coordinate with gamma-polyglutamic acid-, the advantage of the two can be given full play of, common utilization ratio and the fertilizer efficiency rate improving bio-feritlizer.
The production of gamma-polyglutamic acid-can have the technology of biological fermentation to produce on a large scale, the nitrogen nutrition utilization ratio of fertilizer can be improved, certain water retention is had again to plant, the water consumption needed for plant-growth can be reduced, but as the functional additive of suitable fertilizer, its effect and efficiency are also far from bringing into play completely; How to screen and can produce synergistic material with gamma-polyglutamic acid-, and a kind of biologic compound fertilizer of joint development, thus improve the useful effect of gamma-polyglutamic acid-, for country and peasant provide more effectively and the microbial compound bacterial fertilizer saved, thus create larger Social benefit and economic benefit.
