Description
Technical field
The present invention relates to the mixture of fertilizer and other composition, specifically, relate to the fertilizer that is added with trace element and sterilant.
Background technology
The plantation of cash crop, effectively prevention and elimination of disease and pests of requirement, quality is high simultaneously, output is large.For a long time, the disease of the cash crop such as tobacco, watermelon fails effectively to be prevented and treated as soil-borne disease, seed-borne disease etc., can not plant by continuous cropping when causing plantation, and crop quality also constantly descends.Trace it to its cause, the one, soil-borne disease fails to eliminate, and next year then plants, and soil-borne disease is more rampant, can't administer; The 2nd, execute nitrogen-phosphorus-potassium compound fertilizer the first year more when planting, and lacks other essential nutritive element such as trace element, these elements in soil by last year crop take away, as replenishing, must cause these elements deficient, can not meet the needs of next year crop.Why Here it is is difficult to establish for a long time in a place reason of famous-brand and high-quality agricultural-food.Although people study, have developed many trace element fertilizers, such as No. 92110214.3 " compound trace element liquid fertilizer ", No. 98111578.0 " multiple trace element formula fertilizers " of Chinese patent, No. 02113524.X " compound trace element fertilizer enriched in selenium ", No. 200410029779.6 " production technique of organic chelated trace element fertilizer ", No. 200680052549.9 " mineral manure that comprise the biological processing of trace element " etc., but can not solve the problem of soil-borne disease.
Silver has the function of eliminating soil-borne disease and seed-borne disease, and does not produce resistance, also nontoxic, safety.Silver has broad-spectrum bactericidal action, can produce various bacteria known today, virus, fungi and suppress and killing action.The high effect of silver sterilization, actual working concentration 0.1 * 10
-6(being 0.1ppm) Shi Yineng effectively kills various bacteria, virus and fungi.Silver is all nontoxic to human body and crop, does not also produce any resistance, can use for many years and need not to change.Yet up to now, not yet see silver is used among fertilizer, make it to possess the report of sterilizing function, also there is no the patented technology of being correlated with.
Summary of the invention
Purpose of the present invention just is to provide a kind of Bactericidal fertilizer, and increase can adapt to the fertilizer new variety with germicidal action of agricultural development demand.
Another purpose of the present invention is to provide the manufacture method of described Bactericidal fertilizer, in order to produce the fertilizer with germicidal action that is fit to the crop needs.
A further object of the present invention also is to provide the application method of described Bactericidal fertilizer, can be the cash crop service in rural area.
The contriver is in years of researches and practice, find that silver is desirable sterilization material, but, silver also fails to be widely used, this is because when reality is used, need soluble silver salt is soluble in water, and institute's water mostly is natural river water, lake water, spring and tap water, wherein impurity is many, and salt, alkali and most of negatively charged ion that silver ions is met in impurity just produce precipitation.During with the soluble silver salt sterilization, most of silver ionss are all consumed by these precipitations, really can be used for the silver ions of sterilization seldom, do not have germicidal action; If it is valuable very uneconomical because of silver to strengthen consumption.Secondly silver ions sees that light easily decomposes, and is difficult to use under daylight.Silver ions, also can be fixed by adsorption by soil when filling with root precipitation except consuming in water, is used for preventing and treating the soil-borne disease difficulty and works.For this reason, the contriver selects non-ionic silver-colored agent as sterilant through exploring, and has successfully solved the difficult problem with silver-colored sterilization, develops Bactericidal fertilizer.
The Bactericidal fertilizer that the contriver provides, its raw material is composed as follows:

The contriver points out: add as required and contain the selenium thing to produce rich selenium product, the described selenium thing that contains is Sodium Selenite or selenium oxide, adds the mass ratio that contains the selenium thing≤5%.
Above-mentioned complex silver or its nanometer colloid are chitosan complex silvers, two ammino silver, EDTA silver, two sulphur cyanogen close silver, oxine silver, quadrol (En) silver, nitrilotriacetic acid (NTA) silver, triethylene four ammonia silver, pyridine (Py) silver, dipyridyl (DiPy) silver, acetylacetone based (AcAc) silver, dithio sulfuric acid closes one or more in silver.
The Bactericidal fertilizer production method that the contriver provides is:
The first step is taken various raw materials according to composition of raw materials, and solubility azophoska and trace element, magnesium salts are broken to 60～80 orders at 50 ℃～90 ℃ lower ovendry powers, and is mixed, gets dry fine powder;
Second step is scattered in nanometer silver or complex silver or its nanometer colloid in dehydrated alcohol, adds oxidation inhibitor, anti UV agent, stablizer, dispersion agent, stirs 5～30min;
The 3rd step slowly added aforementioned dry fine powder in argentiferous ethanol component in plastic containers, and the limit edged stirs, churning time 10～30min;
In the 4th step, after being crushed to 60～80 orders, mix all the other compositions;
The 5th step with above each component, was placed in encloses container and mixes, stirs evenly, then vacuumize, and allowed ethanol volatilize, and collected ethanol and recycled;
The 6th step after whole ethanol are taken out to the greatest extent, stirred evenly product, carried out vacuum packaging.
The Bactericidal fertilizer application method that the contriver provides comprises:
(1) be used for to soak crop seed after being watered, but sterilization and make crop yield;
(2) be watered the rear filling root that is used for, can kill the multiple pathogeny of crop, but and the continuous cropping plantation;
(3) be used for foliage-spray after being watered, can kill multiple germ on the crop such as flue-cured tobacco blade face, and quality improves, increase yield significantly;
(3) be watered the rear soilless culture that is used for, directly as nutritive medium.
Method without sterilization fertilizer and Manufacture and application thereof provided by the invention can be produced the fertilizer product that contains silver-colored sterilant, satisfies cash crop plantation and the needs of cultivating, and promotes the development of agriculture production.
