Abstract
The invention relates to a sustained-dissolved type chemical fertilizer which comprises the following raw materials in parts by weight: 50-60 parts of organic chemical fertilizer, 5-15 parts of alkenyl succinic anhydride starch ester, 10-15 parts of phosphate esterified starch, 5-10 parts of cross-linking starch and 0.1-0.5 part of nucleating agent. Esterified starch of different substitution degrees can be selected according to plant nutrient requiring periods, the dissolution speed can be effectively controlled, and a stable controlled-release function is achieved.
Description
Technical field
The present invention relates to a kind of slow molten type chemical fertilizer.
Background technology
Along with agrotechnical development, chemical fertilizer plays a part more and more important in agricultural, has progressively occurred at present compound manure, nano fertilizer, organic fertilizer, green fertilizer, concentrated fertilizer etc.But in the use of fertilizer, there is two large problems: the one, fertilizer amount is large, and utilization ratio is low; The 2nd, chemical fertilizer application is unreasonable causes fertilizer loss environmental pollution, and quality of agricultural product reduces.Data presentation according to the relevent statistics: the grain of every kilogram of chemical fertilizer volume increase of China is not as good as half of world average level, not as good as 1/3 of U.S.'s mean level (ML).Be mainly because China's chemical fertilizer utilization ratio is low, in the chemical fertilizer person who lives in exile environment of about 40-60%, fail to play fertilizer efficiency, cause the deterioration of the ecological environment.Therefore utilizing different technological methods to improve utilization rate of fertilizer is to study the core that how to stop or reduce chemical fertilizer nutrient losing issue.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of can be degradable, noresidue, the slow molten type chemical fertilizer that plant is had no side effect.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of slow molten type chemical fertilizer, the raw material that comprises following parts by weight: organic chemical fertilizer 50-60 part, alkenyl succinic anhydride starch ester 5-15 part, organic phosphate starch 10-15 part, cross-linking starch 5-10 part, nucleator 0.1-0.5 part.
The invention has the beneficial effects as follows:
The present invention can need the cycle according to plant nutrient, selects the esterification starch of different degree of substitution, can effectively control dissolution rate, has stable control-release function.The present invention progressively discharges chemical fertilizer, can be degradable, and noresidue, has no side effect to plant, free from environmental pollution, and production efficiency is high, and cost is low, can in common farm crop, extensively promote the use of.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described slow molten type chemical fertilizer preferred value comprises the raw material of following parts by weight: organic chemical fertilizer 52-58 part, alkenyl succinic anhydride starch ester 7-13 part, organic phosphate starch 12-14 part, cross-linking starch 6-8 part, nucleator 0.2-0.4 part.
Optimum value comprises the raw material of following parts by weight: 55 parts of organic chemical fertilizers, 10 parts of alkenyl succinic anhydride starch esters, 13 parts of organic phosphate starchs, 7 parts of cross-linking starchs, 0.3 part of nucleator.
Further, described cross-linking starch is any one in oxalic dialdehyde starch, phosphorus oxytrichloride starch, epoxy chloropropane starch.
Further, described nucleator is any one in Sodium Benzoate, toluylic acid aluminium, hexanodioic acid sodium, Sodium glutarate.
Cross-linking starch is a kind of new synthetic, belongs to a kind of in modified starch.
Cross-linking starch be take starch as raw material, take phosphorus oxychloride, Trisodium trimetaphosphate, hexanodioic acid, hexametaphosphate is linking agent, sodium hydroxide is catalyzer, starch is cross-linked, its transmittance of starch after crosslinked reduces, resistance to acids and bases, resistance to mechanical workout, endurance of cutting strengthens, and gellifying property improves. but water-retaining capacity weakens.
The alcoholic extract hydroxyl group of starch molecule is in the chemical reagent reaction that contains binary or polynary functional group, makes to join together to present the cancellated starch derivative of hyperspace between the hydroxyl of different starch molecules.
The reaction control of cross-linking starch has high stability to heat, acid and shearing force impact.Industrial, often combine employing with other denaturation method, make product there is more practical, more effective characteristic.
In foodstuffs industry, as thickening material and stablizer.Can make the thickening material of salad juice.
Cross-linking starch has higher freeze-stable and freeze-thaw stability, is particularly suitable for applying in frozen product.Freezing or the freeze thawing in the low temperature long period, melts repeatedly, and food still keeps original weave construction, does not change.
Denaturated starch by acid is the main raw material of ice cream after crosslinked.
Cross-linking starch after roller drying can increase cake volume, makes crisp, the soft and resistance to storage of cake.
On medicine industry, as release agent and the lubricant of rubber item.
In paper industry, because cross-linking starch is heated under normal pressure, grain expansion ought not break, many by l Water Paper page sorption amount, therefore good for papermaking hollander sizing efficiency.The anti-mechanical shearing stability of cross-linking starch is high, is the good sizing agent of fluting board and carton paper.
In textile industry, use cross-linking starch sizing, being easy to be attached to increases wear resistance and heat-resistant stability on fiber surface.
