Description

A kind of preparation method and product of mangrove special liquid compoiste fertilizer
Technical field
The present invention relates to a kind of organic fertilizer, and in particular to a kind of preparation method of mangrove special liquid compoiste fertilizer And product.
Background technology
The fertilizer that tradition is applied to mangrove is mainly inorganic fertilizer and foliar fertilizer.For inorganic fertilizer, due to mangrove Growth conditions is poor, slower to the absorption rate of inorganic fertilizer, easily occurs not having enough time also absorbing the feelings taken away by seawater Condition, and then cause fertilizer supply insufficient, slow-growing, survival rate is relatively low.For foliar fertilizer, foliar fertilizer is in application pair Plant has burn seedlings risk in itself;On the other hand, blade face needs repeatedly to spray, and not only workload is big but also cost of labor is high.
During alcohol is produced as fermenting raw materials using molasses, alcohol waste mash will be produced.Due to alcohol waste mash COD, BOD it is very high, pH value is relatively low, but also contains the composition such as substantial amounts of organic matter and nitrogen, potassium, if not being acted upon, directly Discharge, will cause environment pollution, can also cause the waste of the manure resources such as useful nitrogen, potassium.
Have not yet to see mangrove made from alcohol waste mash and potassium nitrate, amino acid progress chelatropic reaction is special The relevant report of liquid organic composite fertilizer.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of preparation method of mangrove special liquid compoiste fertilizer and Product.Inorganic states potassium and nitrogen more than 90% are converted into potassio methionine and potassio cystine etc. in product obtained by this method Organic potassium and nitrogen, mangrove can be effectively improved to potassium, the absorption rate of nitrogen.
The preparation method of mangrove special liquid compoiste fertilizer of the present invention, comprises the following steps:
1) take potassium nitrate and amino acid to be dissolved in the water, chelating >=48h is vibrated under the conditions of≤60 DEG C, obtain chelating liquid; Wherein, the amount ratio of potassium nitrate, amino acid and water is:30-50g:300-600g:3-4L;
2) alkyl benzene sulphonate potassium and alcohol waste mash are added into chelating liquid, chelating >=24h are stirred under the conditions of≤60 DEG C, Obtain mangrove special liquid compoiste fertilizer;Wherein, the addition of alkyl benzene sulphonate potassium adds 1-3g by every liter of chelating liquid Calculate, the volume ratio for chelating liquid and alcohol waste mash is 1:0.8-1.2.
In the step 1) of above-mentioned preparation method, the amount ratio of the potassium nitrate, amino acid and water is preferably:40g:400- 500g:3-4L.Potassium nitrate and amino acid are first preferably subjected to chelatropic reaction again with water wiring solution-forming respectively, specifically, can incite somebody to action Potassium nitrate is made into the 30-50g/L aqueous solution, the aqueous solution by amino acid ligand into 300-600g/L, is then mixed further according to ratio After carry out vibration chelatropic reaction.
In the step 1) of above-mentioned preparation method, described amino acid is the agricultural use that can be bought directly from the market Composite aminophenol powder, the amino acid original powder produced such as Jinan great plan Chemical Co., Ltd., the limited public affairs of Xuzhou green source agricultural science and technology Take charge of the agricultural amino acid original powder of production, agricultural amino acid powder that Shandong Yang Dao bio tech ltd produces etc..
In the step 1) of above-mentioned preparation method, chelatropic reaction is preferably carried out under the conditions of 35-45 DEG C, and the time is preferably 72-80h;The frequency of concussion is preferably 60-120 pendulum/min.
In the step 2) of above-mentioned preparation method, preferably chelatropic reaction is carried out under the conditions of 25-35 DEG C, time 48-60h; The speed of stirring is preferably 20-40r/min.
In the step 2) of above-mentioned preparation method, the addition of alkyl benzene sulphonate potassium is preferably added based on 2g by every liter of chelating liquid Calculate, the volume ratio for chelating liquid and alcohol waste mash is preferably 1:1.
Present invention additionally comprises the mangrove special liquid compoiste fertilizer being prepared by the above method.
Compared with prior art, the method have the characteristics that:
The 1st, potassium nitrate and amino acid are entered under certain temperature to Mobile state concussion chelating in water, then add adhesive with Alcohol waste mash containing compound bacteria, a variety of nutriments enters Mobile state chelating again, further promotes potassium and nitrogen to organic Conversion, the stable absorption of mangrove during being advantageous to subsequent applications.
2nd, the compoiste fertilizer obtained by the method for the invention is different from common fermentation mixed liquor (common fermentation mixed liquor In potassium be substantially inorganic states potassium ion), but a kind of chelating liquid, inorganic potassium therein have been largely converted into potassio egg ammonia Acid and organic potassium and the nitrogen such as potassio cystine, specifically, the inorganic states potassium and nitrogen of the inside is by double chelatings, wherein more than 90% Organic potassium and the nitrogen such as potassio methionine and potassio cystine are had been converted into, eliminates murder by poisoning risk;On the other hand also save significantly The about usage amount of potassium nitrate raw material, can save more than 60%.
