Abstract
The present invention relates to a kind of urea with magnetic function and production method thereof.This urea is to be 10% poly aspartic acid solution composition by urea and weight percent concentration, and both weight ratios are (400～600): (1.3～1.7).Production method is: be 10% poly aspartic acid solution with urea and weight percent concentration by (400～600): the weight ratio of (1.3～1.7) mixes.The economic formula of this urea with magnetic function, function is lasting, and over-all properties is higher, and (as: interpolation of poly aspartic acid not only can be brought into play outside the effect of himself, and can improve the utilization ratio and the specific absorption of urea greatly, significantly improve crop yield, and can improve soil quality); The production method of this urea with magnetic function, its technology is simple, and use equipment is few.
Description
Technical field
The present invention relates to a kind of chemical fertilizer, more particularly, the present invention relates to a kind of urea with magnetic function, simultaneously, the invention still further relates to a kind of production method of described urea with magnetic function.
Background technology
As the nitrogenous fertilizer of plant, its decomposition rate in soil is fast usually for urea, and some nutritive ingredient often has little time by plant absorbing can not to bring into play the getting fat effect well just along with current have lost.Therefore, the utilization ratio of urea has only 20～30%, does not the highlyest also reach 40%, causes the significant wastage of manure resources.How dropping into less manpower, financial resources and make the nutritive ingredient in the urea be fully used, is those skilled in the art's urgent problems.
Summary of the invention
Technical problem to be solved by this invention provides a kind of urea utilization ratio and the higher urea with magnetic function of specific absorption, its economic formula, and function is lasting; A kind of production method of this urea with magnetic function is provided simultaneously, and this method technology is simple, and use equipment is few.
For solving the problems of the technologies described above, the invention provides a kind of urea with magnetic function, it is to be 10% poly aspartic acid solution composition by urea and weight percent concentration, and both weight ratios are (400～600): (1.3～1.7).
The production method of this urea with magnetic function is: be 10% poly aspartic acid solution with urea and weight percent concentration by (400～600): the weight ratio of (1.3～1.7) mixes.
The physical and chemical index of poly aspartic acid is:
The amber transparent liquid of outward appearance
Solids content % 〉=40.0
Density (20 ℃) g/cm3 〉=1.20
PH value (1% aqueous solution) 9.0～11.0
Poly aspartic acid (English name PASP) belongs to the class in the polyamino acid.Poly aspartic acid ruptures because of the peptide bond on its structure main chain is subject to effects such as microorganism, fungi, and the eventual degradation product is the water and the carbonic acid gas of environmental sound.Therefore, poly aspartic acid is good, the environmentally friendly chemical of biological degradability, can be applicable to fields such as water treatment, medicine, agricultural, daily use chemicals, and its relative molecular mass is 1000～5000, and is nontoxic, is a kind of polymer green chemical.
Confirm that through experimental data poly aspartic acid is applied to agricultural following advantage:
1, can be used as synergistic agent, saving urea, the protection ecology of urea.After poly aspartic acid is manured into soil, because its distinctive molecular structure (containing a plurality of carboxyls), they can be rapidly and the nutrient ionic bond of urea, can enriched in nitrogen supply farm crop, and form a miniature fertilizer storehouse, institute's bonded nutrient ion and farm crop root system excretory H
+Exchange is finished the nutrient ion by the process of crop absorption, thereby farm crop are had full nutrition, excite the effect of bioenzyme activity, effectively promotes farm crop to nutrient absorbing, improves disease-resistant, the anti-adversity ability of farm crop; Poly aspartic acid also can form inner complex with micro-metals (as two valence metal ions such as calcium, magnesium, copper, iron), changes the crystals of calcium salts structure, makes its formation water soluble ion attitude and becomes the state that is easy to absorb; Two aspect effects make eutrophication, the activation of urea, make farm crop more effectively utilize nutritive ingredient in the urea, and the urea utilization ratio can improve 20%～30%, thereby reduce the environmental pollution that lavishment urea causes.
2, coordinate nutrient, raising quality.According to experiment confirm, poly aspartic acid can not only improve the biomass of farm crop, and can play original promoter action to the absorption of trace element (as nitrogen, phosphorus, potassium, zinc, manganese, iron etc.).This is the rich zinc of Development and Production, characteristic vegetables, fruit such as Fu Meng, Fu Tie, and increasing farmers' income provides strong technical support.
3, increase drug effect, the convenient use.Poly aspartic acid is a kind of water-soluble high-molecular substance, has good diffusion, penetrating power.
4, improve the soil, culture fertility.Use poly aspartic acid, can increase beneficial microorganism total amount in the soil, improve soil water-retaining and ventilation property, improve edatope, strengthen soil fertility.
5, increasing both production and income, benefit are obvious.Show by experiment, after poly aspartic acid uses, can make food crop volume increase 10～15%, cash crop volume increase 20～35%; Also can promote precocity, listing in advance.
Therefore, the interpolation of poly aspartic acid not only can be brought into play outside the effect of himself, and can improve the utilization ratio and the specific absorption of urea greatly, significantly improves crop yield, and can improve soil quality.
In sum, the economic formula of this urea with magnetic function, function is lasting, and over-all properties is higher; The production method of this urea with magnetic function, its technology is simple, and use equipment is few.
Urea, poly aspartic acid in this urea with magnetic function are commercially available product.
