Description
Technical field
The invention belongs to agriculture field, it is related to a kind of phosphorus element fertilizer synergist and preparation method thereof.
Background technique
Phosphorus is one of mineral element necessary to plant growth, participates in the intracorporal photosynthesis of plant and life in a variety of forms
Biochemical process is managed, is played a significant role to promotion plant growth and development and metabolism.However, phosphate fertilizer is also sharp in all fertilizer
Minimum with rate, this season utilization rate only has 10%~25%.It on the one hand is that diffusion length is no more than 2cm, plant to phosphorus in the soil
Root system can only absorb neighbouring phosphorus；On the other hand due to it, which precipitates the factor with iron, aluminium, calcium and the magnesium etc. in soil, forms difficulty
The phosphate of capacitive.Therefore, phosphorus fixation how is reduced as possible and increases phosphorus and root system contact area, and improving phosphate fertilizer utilization efficiency is
Problem to be solved.
Summary of the invention
To solve the above-mentioned problems, the purpose of the present invention is to provide a kind of phosphorus element fertilizer synergist, which increases
Effect agent can promote plant growth, improvement soil, and can reduce the soil fixing of phosphorus element, and immobilization phosphorus and difficulty in energy activating soil
Insoluble inorganic phosphorus improves the low problem of phosphorus element utilization rate of fertilizer.
Another object of the present invention is to provide the preparation methods of above-mentioned phosphorus element fertilizer synergist.
To achieve the goals above, the present invention provides a kind of phosphorus element fertilizer synergist, by as follows at being grouped as:
Wherein, marine algae extract is in terms of dry matter content.
Wherein the filler is clay or bentonite.
The present invention also provides the preparation methods of above-mentioned phosphorus element fertilizer synergist, include the following steps:
(1) by by the marine algae extract of enzymatic hydrolysis, being diluted with water to moisture content is 55~75%, squeezes into stirring through metering pump
In tank；
(2) seaweed in potassium humate or fulvic acid, poly-aspartate and filler, with blender is added into agitator tank
Extract stirs together, is sufficiently mixed under room temperature uniformly；
(3) feed liquid being uniformly mixed in step (2) is dispensed by being granulated, after dry, cooling.
Wherein, the marine algae extract the preparation method comprises the following steps:
(1) a) by the clear water immersion 2h of 5~6 times of volumes of dry seaweed, then rinse 2~3 times, after rejecting seaweed root and sundries
It puts into cutter, cuts into 10~20cm fragment, it is spare after centrifugal dehydration；Or b) fresh seaweed is directly rinsed 2~3 times, is cut
It is cut into 10~20cm fragment, it is spare after centrifugal dehydration；
(2) seaweed sheared is taken, is placed in reaction kettle, clear water, adding citric acid is added in seaweed and water ratio 1:1~2
Adjusting pH value is 5~6.5, and cellulase and amylase is added according to seaweed quality 1~1.5%, and temperature is controlled at 45~60 DEG C,
Mixing speed reacts 24~48h under the conditions of being 100~250r/min, and reaction solution is then down to room temperature, is ground into through colloid mill
60~100 mesh, repressurization is into preservative tank, and the copper sulphate that seaweed liquid weight 0.15% is added carries out anti-corrosion, after mixing evenly temporarily
It deposits, both obtains marine algae extract.
Preferably, the mass ratio of the cellulase and amylase is 1.5~2:1.
Marine algae extract used in the present invention is to extract to obtain through biological-chemical method as raw material using seaweed, wherein rich in more
Kind active material, such as algal polysaccharides, highly unsaturated fatty acid and auximone, gibberellin, the class basic element of cell division, Polyphenols
A variety of natural plants growth regulators such as compound can promote root system of plant prosperity, enhance plant stress-resistance, disease-resistant and resistant to lodging energy
Power.
Humic acid used in the present invention is the main component of the soil organism, has loose " cavernous body " structure, and be rich in
A variety of functional groups such as carboxyl, phenolic hydroxyl group, aldehyde radical mostly use as fertilizer and soil conditioner.The preferable potassium humate of dissolubility
Or fulvic acid, can not only promote plant growth, improve crop anti-adversity ability, also easily with the Fe in environment3+、Al3+、Ca2+Equal metals
Ion complexation.Therefore, potassium humate or fulvic acid can both pass through the bridging action and HPO of metal ion4 2-And H2PO4 -Indirectly
Connection can also directly be complexed, to improve transfer ability of the phosphorus element in Soil Micro-environment with phosphate.
Poly-aspartate used in the present invention is a kind of superpower high molecular polymer of water imbibition for being polymerized by amino acid,
Can have in itself good biocompatibility and biodegradable with the carboxylic acid side group of complexing of metal ion with a large amount of, be
A kind of extremely wide " green " chemicals of purposes.Poly-aspartate is used as water treatment agent always, mainly in Shui Chu
Scale inhibition, dispersion are played in reason, have corrosion inhibition concurrently.It has recently found that poly-aspartate can absorb the moisture in Soil Surrounding environment,
Liquid microenvironment is formed, to promote the phosphate dissolution of phosphate dissolution or soil colloid absorption in soil.Due to poly- asparagus fern
Propylhomoserin has the nitrogen in Enriching soil, phosphorus, potassium and microelement characteristic, in the present invention main poly-aspartate mainly use its compared with
Strong water absorption character.
Marine algae extract is seaweed extracted liquor in the present invention, is to be obtained using seaweed as raw material by enzymic fermentation technology, contains
Water rate 75~90%, dry matter content 15~25%, wherein seaweed acid content is more than or equal to 5%, and GA content is more than or equal to
20ng/g, the content of organic matter are more than or equal to 10%, and content described above is mass content.In fertilizer synergist preparation process
In, using moisture in seaweed extracted liquor as the adhesive of particle, a group of the solid component as synergist in seaweed extract
Point.After seaweed is extracted in production, directly uses, do not dry, usage amount is then calculated according to dry matter content.
Phosphorus element fertilizer synergist provided by the invention is cooperated by Plant growth-promoting effect agent and Phosphorus in Soil migration aids,
Middle Plant growth-promoting effect agent includes marine algae extract and potassium humate or fulvic acid；Phosphorous movement auxiliary agent is by potassium humate or fulvic acid
It is formed with poly-aspartate.
The beneficial effects of the present invention are:
Phosphorus element fertilizer synergist provided by the invention can be applied directly in the soil, apply after also mixing with phosphate fertilizer, make phosphorus
Plain this season utilization rate greatly improves.
