Description
Technical field
It is a kind of synergist YL-101 and its application, specially one the present invention relates to agricultural fertilizer synergist technical field
Plant iminobisuccinate and small peptide block copolymer and its application.
Background technology
With the fast development of agricultural, it is that a large amount of of chemical fertilizer use, causes the common salinization of soil of soil and severe environments are dirty
Dye.Grain vegetables quality decline, mouthfeel is not good, more seriously, and substantial amounts of nitrate, excessive nitrogen phosphorus can be accumulated in soil
Deng can also pollute underground and surface water.Being irrigated using the water rich in nitrate can raise the nitrate content in crops,
And nitrate may be reduced into carcinogenic substance nitrite in human body, the outburst of various cancers and disease is directly resulted in.
The stable yields volume increase of agricultural, be unable to do without fertilizer synergist.Fertilizer synergist, including fertilizer slow-release formulation and nutrient huge legendary turtle
Mixture：Wherein fertilizer slow-release formulation, based on polypeptide, nutrient intercalating agent, using EDTA and iminodisuccinic acid as representative.
Peptide, it is believed that be so that peptide bond is connected and obtains between one or more amino acid, due to intermolecular peptide bond (acid amides
Key) and molecule on dissociate carboxyl isopolarity group, sustained-release synergistic can be played, simultaneously by molecular separating force come activated fertilizer
Fertilizer synergist can be commonly used as with activating soil.But it is poor with chelant power itself, if with Fertilizer combination power, add pair
The nutrient chelant bad dispersibility such as calcium, magnesium, zinc, iron, copper, precipitation by metallic ion precipitation is had under alkalescence, production is had a strong impact on
Quality and use.Such as patent 201110326607.5 prepares calcium polyaspartate, and 201210097230.5 prepare poly- asparagus fern
Propylhomoserin zinc, finally all exists with acid solution.
A kind of sodium of iminodisuccinic acid four, emerging intercalating agent, is just widely used as fertilizer synergist.Although comparing
In EDTA, it possesses degradable green, and the special efficacy of chelant metallic element and amino acid can be supplemented to plant, but it is
Small-molecule substance, easily with soil erosion, easily failure；Easily it is absorbed by plants, lacks persistence；The fertilizer such as urea are lacked and are sustained
Property the shortcomings of, also greatly limit its fertilizer and agricultural in application and effect.
Agricultural is in the urgent need to a kind of new chelating dispersing agent at present, and as fertilizer synergist, it is the sustained release for possessing polypeptide
Dispersiveness, but also with the chelant of iminodisuccinic acid, and degradable green, do not endanger environment.In the prior art, also not
Seeing has related open and studies.
The content of the invention
The present invention provides a kind of iminobisuccinate and small peptide block copolymerization aiming at above-mentioned defect
Thing and its application.Block copolymer of the present invention possesses sustained release dispersiveness, embedded iminodisuccinic acid, tool using polypeptide as main chain
Standby chelant, both are organically merged, as fertilizer synergist, play the dual of slow release fertilizer and chelant metallic element
Effect.
A kind of iminobisuccinate and small peptide block copolymer and its application technology scheme of the present invention be, Yi Zhongzeng
Agent YL-101 is imitated, is a kind of iminobisuccinate and small peptide block copolymer, the block copolymer includes monomer A and monomer
B, described block copolymer be without returning copolymer or have rule copolymer, wherein, A be iminobisuccinate and/or its spread out
Biology, B is small peptide and/or its derivative.
A structure is：M is H+, Na+, K+, Ca2+, Zn2+, Mg2+, Cu2+,
Mn2+, Fe3+At least one of.
B is asparatate, aspartate, aspartic acid derivate, glutamic acid, glutamate, glutamic acid spread out
At least one of biology.
B is: In at least one
Kind；
Wherein, M is H+, Na+, K+, Ca2+, Zn2+, Mg2+, Cu2+, Mn2+, Fe3+At least one of.
A kind of synergist YL-101, using small peptide and/or its derivative as main chain, embedded iminobisuccinate and/or
Its derivative.
The unit mol ratio of small peptide and/or its derivative and iminobisuccinate and/or its derivative is=2:1~
1：1.
Monomer A is to be connected to be constituted with peptide bond with monomer B.
Described synergist YL-101 be used as fertilizer synergist, play fat-reducing increase production and improve productivity and improved soil effect.
Beneficial effects of the present invention are：The block copolymer of the present invention possesses slow using small peptide and/or its derivative as main chain
Dispersiveness, embedded iminobisuccinate and/or its derivative are released, possesses chelant, both are organically merged, its
Dispersive property is better than polypeptide, and chelant performance is better than iminodisuccinic acid, is a kind of new macromolecule chelating dispersing agent, is used as
Fertilizer synergist, plays the double effects of slow release fertilizer and chelant metallic element.Its easily biological-degradable, is used for a long time, no simultaneously
It is enriched with soil, lake, it is free from environmental pollution, plant will not be made to develop immunity to drugs；It is degraded to the small-molecule substances such as amino acid,
Amino acid is supplemented to plant.
The present invention block copolymer can be added to by a certain percentage urea, composite fertilizer, foliar fertilizer, Water soluble fertilizer, organic fertilizer,
In bacterial manure, as fertilizer synergist, the exclusive use of plant nutrient accelerator can also be directly used as, plays what fat-reducing was increased production and improved productivity
Effect.
