Description

A kind of freeze proof aminoacid foliar fertilizer and preparation method thereof

Technical field

The invention belongs to the Technology field of fertilizer, be specifically related to a kind of freeze proof aminoacid foliar fertilizer and preparation method thereof.

Background technology

Foliage fertilizer is that nutritive element is applied to farm crop blade surface; a kind of fertilizer type of its function is played by the absorption of blade; the blade of plant has upper and lower two-layer epidermis; be made up of epidermic cell; on table, there are stratum corneum and wax in the outside of cell, can protect the functions such as the enforcement of the mesophyll cell under face tissue is photosynthetic, breathing, by the impact of extraneous unfavourable condition change; blade surface also has many small pores, exercises the function that gas is changed.Research shows, stratum corneum is made up of a kind of Long carbon chain fatty acid polymer with hydroxyl and carboxyl, hydroxyl on the molecular gap of this polymkeric substance and molecule, carboxylated hydrophilic group can allow the aqueous solution penetrate in leaf, certainly, the pore of blade surface is that foliage fertilizer enters blade passage more easily.In chemical fertilizer, the stratum corneum of urea class material to epidermic cell has ramollescence, can accelerate the infiltration of other nutritive substance, so urea becomes the important moiety of foliage fertilizer.

The method for hydrolysis of protein mainly contains acid hydrolysis, water breakthrough solution and enzymic hydrolysis.The present invention uses acid-hydrolyzed method, in atmospheric conditions, concentration of hydrochloric acid optimal concentration when testing 110 DEG C, select same materials pig hair, the concentration of hydrochloric acid selected respectively is 12mol/L, 6mol/L and 2mol/L, wherein hydrochloric acid (ml) is respectively 2: 1,3: 1,4: 1,6: 1,8: 1 and 10: 1 with the proportioning of pig hair (g), then detects content amino acid whose in reactor at set intervals.According to showing that data show, be 4: 1 in hydrochloric acid (ml) and pig hair (g) proportioning, under the condition of hydrolysis time 15h, the aminoacids content of pig hair hydrolyzed solution is the highest 84.76%, and the result that different time is surveyed is all without significant difference.Due to along with the increase gradually by acid amount, the energy that next step decompression depickling is expended increases, and also can cause the waste of the energy.Therefore, consider from the cost-saving angle with the energy, the present invention adopts 6mol/L hydrochloric acid to be hydrolyzed, and the ratio of hydrochloric acid and material is about 4: 1, and hydrolysis time is 14 ~ 18h, can reach optimal hydrolysis effect.

Dimethyl dodecyl amine oxide: colourless to pale yellow viscous liquid, a kind of amphoterics, colourless transparent liquid, for weak cation tensio-active agent, in cationic in acidic medium, in nonionic in alkaline medium, there is good thickening, antistatic, soft, foam enhancing and detergency ability; This product pungency is low, effectively can reduce the negatively charged ion pungency in washing composition, also has the features such as sterilization, calcium soap dispersion, readily biodegradable.

Alkyl glycoside is the more comprehensive new non-ionic surfactants of a kind of performance, have the characteristic of conventional nonionic and ionic surface active agent concurrently, having high surface, good ecological security and intermiscibility, is internationally recognized first-selection " green " functional surfactant.

The effect of promoting agent is the penetrating quality increasing foliar nutrient, improve utilization rate of fertilizer, foliage fertilizer absorbs mainly through the blade of plant, promoting agent of the present invention contains kinds of surface active substance, the penetrating power of liquid fertilizer can be improved, reduce the surface tension of liquid fertilizer, increase the contact area of Liquid Fertilizer and blade, slow down velocity of evaporation, penetration enhancement, foliage fertilizer excessive concentration or the too fast blade of likely burning of moisture evaporation, cause fertilizer damage, add a certain amount of activity and stimulating component, be conducive to the cutin destroying blade table confluent monolayer cells, improve absorption rate, improve stress resistance of plant.
