Abstract
The fertilizer additive consists of chitosen water collidal solution 0.1-99% and high molecular compound or ethyl acrylate 0-99%. It is used as material to coat various fertilizer or seed. The present invention has the functions of raise fertilizer efficiency, disinfection, improving crop quality and intelligent slow release.
Description
The present invention relates to a kind of fertilizer additive and application.Specifically, relate to a kind of by chitosan or and the composition formed of macromolecular compound, and they are as the application of coating material and fertilizer additive.
Current, being applied to fertilizer of crops mainly is inorganic fertilizer, be characterized in: produce effects is fast, cost is low, be easy to batch production production, but these fertilizer but have decomposition fast, absorption rate is low, run off, the volatilization waste is big, easily causes drawbacks such as soil compaction, and environment also had in various degree pollution.For above-mentioned reasons, people always wish to develop a kind ofly can increase output, can improve not only crop quality and itself but also nontoxic, free of contamination fertilizer.Mostly the method that solves is to wait the purpose that reaches the raising fertilizer efficiency by adding plant-growth regulator or plant-growth trace element and microbial fermentation now, but, these fertilizer can only satisfy the requirement in a certain respect of crop or soil, can't solve comprehensive demand of crop or soil, particularly prevent and improve soil compaction, effectively bio-hormone and enzymic activity and fertilizer carry out needs such as intelligence release in the activated plant body with the plant-growth speed.
In recent years, development, exploitation and report about fertilizer additive are a lot, but with the cell walls of unicellular lower eukaryote mushroom, algae, arthropods shell, mollusk inner casing and cartilage and higher animal be the chitosan that extracts of raw material and with the report that yet there are no of the mixed uniformly composition as fertilizer sources of macromolecular compound additive.
Purpose of the present invention provide a kind of by chitosan or and the fertilizer additive formed of macromolecular compound or the third ethene acid esters, it can improve soil compaction effectively, activated plant body interior bio-hormone and enzymic activity also utilize autacoid antibacterial.
Another object of the present invention provides a kind of application that utilizes above-mentioned fertilizer additive as the material that coats various fertilizer or seed, solves the intelligent slowly-releasing of fertilizer.
A further object of the present invention provides the application of a kind of fertilizer additive in preparing as fertilizer such as plant-growth regulator.
Fertilizer additive component of the present invention is as follows, below is weight part:
Weight percent is 0.1～99 part of 0.1%～50% a chitosan water Colloidal fluid, 0～99 part of the macromolecular compound or the third ethene acid esters.
Macromolecular compound molecular weight 10～3,000,000.
The chitosan molecular weight is 1,000～130,000,000.
Macromolecular compound is following one or more mixing: Vinyl Acetate Copolymer, treated starch, polyacrylamide, carboxymethyl cellulose, ethyl cellulose.
The said third ethene acid esters is one of following or two kinds mixing: the third hexenoic acid ethyl ester, the third hexenoic acid propyl ester.
Its component of said fertilizer additive is that molecular weight is 1,000～30,000,000 chitosan water Colloidal fluid.
The combination of preferred one of following or its arbitrary proportion of macromolecular compound: Vinyl Acetate Copolymer, treated starch, polyacrylamide, molecular weight 100～2,000,000.
More than any application in every as the material that coats various fertilizer or seed.
More than in every any one in the fertilizer preparation as Application of Additives, as be added in the plant-growth regulator, perhaps be added in other organic and inorganic fertilizer.
The chitosan that the present invention uses has another name called chitosan (glucosamine glycan), is a kind of animal fiber polysaccharide, and structural formula is:
Similar to polysaccharose substance such as Mierocrystalline cellulose, be one of wide polyose of occurring in nature distributed pole, with itself and macromolecular compound combination, the as fertilizer sources additive uses, and every 50kg chemical fertilizer uses 100 gram additives, and the mixing recession is executed, and fertilizer efficiency is enhanced about more than once.And can produce the following effect that former fertilizer does not have:
1. can activated plant after using the activity of bio-hormone and enzyme in the body, quicken root growth and mitogenetic, forms strong root system system, promote root system absorbing, preventing to macerate root, rot root to fertilizer.
2. can suppress the mitogenetic and breeding of harmful bacterium in the soil after using, prevention blight, root diseases such as root rot.And can make wheat scab reduce 30%, and root rot reduces 20～60%, and canker of apple fruit, melon dish oidium sickness rate also obviously reduce.
3. can impel a kind of enzyme that kills nematode and worm's ovum of microorganisms in the soil after using, the control of root nematode is had special efficacy.
4. after using, not only can promote crop self to absorb, and can also promote the decomposition utilization of various fertilizer in the soil, improve the fertilizer specific absorption.
5. can effectively promote chlorophyllous synthetic and conversion after using, increase organic matter accumulation, improve output, improve quality.Evidence can improve plant leaf chlorophyll content 10～20%, and can improve nitrate reductase activity more than 30%, makes wheat, corn, soybean, protein content improve 10～30%; The apple degree of staining improves more than 7.9; The fruit pol improves 1～1.5 degree; Vc content improves 10～60%.
Chitosan is a filmogen, composition so that chitosan and macromolecular compound are formed can be used as the dressing that coating material carries out fertilizer or seed and plant, wraps in outside the seed or spray plant leaf surface to have ventilative, the effect of water conservation can promote photosynthesis of plant and nutritive ingredient to absorb.Spray the preharvest period of plant, can strengthen plant resistance to environment stress, seed is easily stored, vegetables, melon and fruit quality guaranteed period prolong.If wrap in outside the fertilizer, can prolong decomposition, the release of fertilizer, play slow releasing function, and can be according to needs and the variation of temperature of plant-growth to nutrient, the burst size of regulating fertilizer automatically reaches the effect that intelligence discharges.
