Description
Technical field
The present invention relates to the technical fields of foliar fertilizer more particularly to a kind of available nitrogen, slow nitrogen of being rich in the blade face of one
Fertile preparation method.
Background technology
Ureaformaldehyde is one of very potential slow-release fertilizer kind, is to react condensation under certain condition by urea and formaldehyde
Made of the mixture that is made of the polymethylene urea of different polymerization degree.But main problem is the portion of low molecular weight in these fertilizer
It is point fast in plant growth initial stage rate of release, and the part of high molecular weight is slow in plant growth later stage rate of release, it is therefore desirable to
It is modified to improve the Nitrogen releasing feature of ureaformaldehyde slow-release fertilizer.In recent years, the report in relation to ureaformaldehyde slow-release fertilizer mainly leads to
The mode of physical blending is crossed to improve its nutrients release.Physical blending can not change the rate of release of nitrogen, slow to ureaformaldehyde
It releases fertilizer and carries out chemical modification, it is the effective means for optimizing release rate of nitrogen to change its molecular structure.
Most of crops, such as rice, wheat meet with root system aging when the later stage being in the milk, expanding or meet with stain evil root system
Asphyxia is significantly reduced from the ability of soil absorption nutrient.Traditional nitrogenous fertilizer includes that urea efficiency is too violent, in crop generative growth phase
Using with greater risk, break the balance of nutrient growth and reproductive growth, causes remaining green when it is due to become yellow and ripe late-maturing;If crop grouting, it is swollen
The big stage can mildly supplement nitrogen, balanced nutrients growth and reproductive growth, reduce middle and lower part cauline leaf nitrogen translocation, promote top
Leaf Vitality greatly enhances photosynthesis, breaks through the bottleneck of crop yield;Urea using during it should be noted that for the use of very
It is more, the time mainly applied fertilizer and dosage are on the one hand needed, too late or excessively can should not lead to remaining green when it is due to become yellow and ripe evening in this way during top dressing
It is ripe.
Present invention mainly solves the improper problems of the control of nitrogen source content in foliar fertilizer, and growth why is not achieved very little to be needed
There is the underproduction in the purpose asked, crop, and nitrogen source is excessive, cause remaining green when it is due to become yellow and ripe late-maturing.

The purpose of crop yield.
The present invention is realized by following technological means solves above-mentioned technical problem:
It is a kind of rich in available nitrogen, slow nitrogen in one foliar fertilizer preparation method
1, before this about the preparation of biochemical fulvic acid, the fermentation material of use is parts by weight(Kg)For the following raw material of unit:Sawdust
10 ~ 15 parts, 6 ~ 12 parts of cotton seed hulls, 2 ~ 5 parts of peat, 5 ~ 10 parts of seafood leftover bits and pieces, 1 ~ 4 part of rice bran be base stock, then in temperature
It is warm(30~35℃)It is moist(Soil water content 80%)Place dig pit landfill, surface covering lotus pool mud is simultaneously capped straw heat preservation,
Retting 25 ~ 35 days, fermentation material is dug and is dried, the powder of ground 60 ~ 120 mesh sieve.
The extraction of biochemical fulvic acid:Fermentation powder adds water in 1: 1 ratio, filters to obtain extracting solution, ferment is readjusted the distribution with sodium hydroxide
Liquid centrifuges 15 min, gained supernatant is crude extract, referred to as A liquid with 4 000 r/min again to pH8~10 after standing 1h;
Wherein contain biochemical humic acid, including biochemical brown humic acid and most biochemical fulvic acid.
Using the spontaneous fermentation that tank fermentation method carries out, using lotus pool mud in complicated microorganism species carry out
Fermentation, fermentation is more thorough, and the microbial activity in nature is stronger.Different from natural fulvic acid, biochemical fulvic acid is aromatic series
Compound, with the functional groups such as hydroxyl, carboxyl, phenolic hydroxyl group, methoxyl group, after measured, amino state in biochemical fulvic acid extracting solution
Peat fulvic acid amino-acid nitrogen content 30 times of the nitrogen content with concentration.Contain 18 kinds of amino acid in biochemical fulvic acid extracting solution,
Its Glutamic Acid (Glu) and tryptophan (Trp) content are higher.Illustrate to contain more amino acid in biochemical fulvic acid refined liquid,
This biochemical fulvic acid related with the effect of microorganism has higher activity than natural fulvic acid.Biochemical fulvic acid is using micro-
What biofermentation was formed, humic acid material is not only contained in extracting solution, contains the growth of other various plants simultaneously beneficial to battalion
It forms point, adjusting and trophism is had to plant growth concurrently, wherein tryptophane is higher, and tryptophan is auximone Yin
The precursor of indolylbutyric acid after being absorbed by plants, can be converted into heteroauxin, this is one of the reason of it promotes plant growth.
2, it is 0.1 ~ 0.3mm dregs of beans to be crushed to granularity, then presses solid-liquid ratio 1:Mass fraction is added in 9 ~ 10 ratio
0.50% KOH dilute alkaline solns are heated to 40 ~ 50 DEG C, and 80r/min is sirred and separated time 50min, to the soybean protein in dregs of beans
Separating treatment is carried out, is after the completion filtered the aqueous solution containing soybean protein, filters out dregs of beans, 40 ~ 50 DEG C of filtrate of heat preservation is simultaneously
Urea is added(It analyzes pure:≥98%)And formalin(It analyzes pure:36~39%), continuously add the KOH dilute alkaline solns of 0.50wt%
It is 8.0 to pH, 1.5 ~ 2.0h of insulation reaction;It is eventually adding saturation phosphoric acid, reaction is terminated after adjusting pH to 4.5 or less 1.0h, institute
It obtains mixed liquor and is known as B liquid.
Soybean protein isolate molecule is in a kind of tight structure of curling, has relative stability, basic unit is by ammonia
The peptide chain that base acid is constituted.Hydrophobic region in the molecular structure of soybean protein isolate is wrapped up by hydrophilic area, therefore many groups
It is wrapped in the inside.The space structure of albumen passes through the non-covalent key-shapeds such as disulfide bond and Van der Waals force, hydrogen bond and electrostatic force
At.After the hydrolysis of potassium hydroxide, legumin molecule just comes from rolled state spread apart, and molecule segment is sufficiently spread out,
The three-level and quaternary structure of soybean protein isolate are destroyed, and originally reactive group of the packet inside coiled structure is exposed.
After soybean separation proteolysis, αhelix transformation forms β-pleated sheet structure.The active group of protolysate can be with first
Aldehyde reaction, and polymerize with urea, it is introduced into the molecular structure of ureaformaldehyde in a manner of block.The original crystalline region of ureaformaldehyde
It is substituted by protolysate, leads to the reduction of its crystallinity.The degree of hydrolysis of protolysate is bigger, the maximum point of modified urea formaldehyde
Temperature where solution rate is higher, closer to the maximum decomposition temperature of ureaformaldehyde, the modified ureaformaldehyde surface porosity of protolysate
It is porous, be conducive to that soil moisture is contacted and kept with microorganism.
When the molar ratio of equivalent urea and formaldehyde is 1.2, modified protolysate rate of release early period slows down,
Later stage rate of release is accelerated, and protolysate degree of hydrolysis is smaller, and the nitrogen release rate of modified ureaformaldehyde is faster.
Modified ureaformaldehyde is slower than unmodified ureaformaldehyde release rate of nitrogen, is because of protolysate and low molecule
The ureaformaldehyde of amount is copolymerized, and molecular weight increases, and slows down its release rate of nitrogen.It is first dropped in degradation initial stage protolysate segment
Solution, as the molecule segment of the extension modified urea formaldehyde of time is disintegrated at fractionlet, in hydrolysis and microbial decomposition
Under, fragment decomposes simultaneously, and Nitrogen releasing accelerates, to meet the needs of plant growth.
A liquid and B liquid are mixed to get to the foliar fertilizer.
