Abstract
The invention provides a method for producing a synergistic phosphatic fertilizer. According to the method, the synergistic phosphatic fertilizer is prepared from alginic acid serving as a synergist and an inorganic phosphatic fertilizer serving as a raw material in a certain ratio by mixing and granulating according to the demands of different crops and soil types on nutrient. The synergistic phosphatic fertilizer can improve a soil structure obviously, improve the utilization rate of the phosphatic fertilizer, enhance the capacity of cold resistance, drought resistance and plant diseases and insect pest prevention and improve the yield and quality of the crops.
Description
Technical field
The invention belongs to the production of phosphate fertilizer technical field, is a kind of working method of synergist of phosphate specifically.
Technical background
Phosphorus all is essential nutrient element to people, animal, plant, it on agricultural importance and not second to nitrogen, lacking on the soil of phosphorus, phosphorus usually often becomes the limiting factor of plant growth, must application of P fertilizer regulate.But phosphate fertilizer is that utilization ratio is minimum in all chemical fertilizer, and this season crop generally can only utilize 10%～25%.Its major cause is that phosphorus is prone to be fixed in soil; Its movability in soil is very little again simultaneously, if phosphate fertilizer is executed soil the inside, a phosphate fertilizer particle; Toward the scope that spreads on every side; Ultra only two centimetres, root system of plant only could absorb it in the very near place of phosphorus, and the volume that root contacts with soil generally only accounts for the 4%-10% of topsoil volume.In addition, phosphorus also very easily with soil in elements such as calcium, magnesium, iron, zinc constitute the compound of insoluble and precipitate, plant can not be absorbed.Therefore, reduce phosphorus fixation as far as possible, prevent the degeneration of phosphorus, increase the contact area of phosphorus and root system, improve phosphate fertilizer utilization efficiency, the unit's of giving full play to phosphate fertilizer greatest benefit is the main direction of phosphate fertilizer development.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of synergist of phosphate.It mainly adopts the biological-chemical combined techniques from the extracting algae Lalgine, is raw material with the marine alga, forms through special biochemical process Processing of Preparation.
The Lalgine active substance that extracts contains a large amount of non-itrogenous organic substances; Has kind of mineral element and abundant VITAMINs surplus the incomparable K of terrestrial plant, Ca, Mg, the I etc. 40; Contain peculiar Sargassum polysaccharides in the marine alga, highly unsaturated fatty acids and multiple natural phant growth regulator especially, like plant hormone, Plant hormones regulators,gibberellins, type phytokinin, polyphenolic substance and antibiotics material etc.These materials have very high biological activity, but the generation of the non-specific activity factor and the balance of regulating endogenous hormones in the stimulating plant body; Promote plant to form bigger root system, to promote the utilization of root to soil nutrient and moisture; Increase the screen casing cell of stem, quicken photosynthate and be transported to other positions from blade; Degeneration-resistant, the disease-resistant worm of enhancement of plant, ability resistant to lodging.In addition; The organism that contains in the Lalgine extract will produce multiple organic acid in decomposition course; These organic acids and Fe, Al, Ca form complex compound, have prevented Fe, Al, Ca to phosphorus fixation, but these organic acids Fe, Al, Ca in tertiary iron phosphate, phosphagel phosphaljel, the calcium phosphate in the complexing native soil also simultaneously; Improve the content and the utilization ratio of available phosphorus in the soil, thereby reach the purpose that increases production and improves productivity.
Lalgine can significantly improve Soil structure as the phosphate fertilizer synergistic agent, and it decomposes the multiple organic acid that produces and can fully combine with phosphate fertilizer; Play control/slow releasing function; The leaching loss that reduces phosphate fertilizer has greatly improved phosphate fertilizer utilization efficiency with fixing, and enhancing crop is cold-resistant, drought resisting, preventing disease and pest ability; Improve crop yield, improve crop quality.
Technical scheme of the present invention is: a kind of synergist of phosphate is characterized in that: comprise synergistic agent Lalgine and phosphate fertilizer, the content of said Lalgine is 0.3～20%, and phosphate fertilizer content is with P
2O
5Molecular weight is calculated as 40%-70%.
Said phosphate fertilizer raw material comprises one or more in phosphoric acid, normal superphosphate, double superhosphate, monoammonium phosphate and the diammonium phosphate.
Described Lalgine prepares through following steps:
(1) takes by weighing dry seaweed, add the formaldehyde solution of marine alga dry weight 10-30 0.5%-1.0% doubly, soak 3-6 h.Soak and finish after-filtration, it is colourless washing to washings, and marine alga is drained, and gets into cylinder drying machine drying, pulverizing;
(2) add dry seaweed weight 10-30 citrate buffer solution (pH5.0-8.0) doubly in the step (1), cellulase 80-150U/g, stirring and evenly mixing, 40 ℃-60 ℃ insulation enzymolysis 3-12 h are warmed up to 90 ℃ and make enzyme deactivation, filter;
(3) Na of dry seaweed weight 10-30 2%-5% doubly in the adding step (1)
2CO
3Solution, digestion 2-5 h;
(4) the thin up Digestive system is suitable to conveniently being filtered into, and filters and washing.In filtrating, slowly add the 6%-10% hydrochloric acid soln again, regulate pH7.0-8.0, remove by filter impurity and also concentrate, promptly get Lalgine solution (Lalgine content is 300g/L).
The making method of described synergist of phosphate is characterized in that, may further comprise the steps:
(1) takes by weighing each material component in the inorganic nutrients;
(2) add Lalgine solution, carry out mixed dissolution;
(3) high tower pellatizer, cylinder granulation or extruder grain;
(4) promptly get.
