Abstract
The present invention relates to granulated boric fertilizer.A kind of Novel multi-effect granulated boric fertilizer, adopt ulexite breeze, borax, boric acid, methylene urea are as pulverulent mixture material, mix by following part by weight, at 60-90 degree temperature and acidic medium condition, carry out polyreaction granulation to obtain, wherein each raw material weight number is as follows: ulexite breeze 30-60; Borax 0-40; Boric acid 0-20; Methylene urea 5-10; Acidic medium is one or more in the vitriol oil, phosphoric acid, citric acid.The present invention adopts ulexite breeze, borax, boric acid, methylene urea, according to corresponding proportion, under certain temperature and acidic medium condition, carries out polyreaction granulation, and obtained product particle is even, mellow and full, and intensity is high, good fluidity.Quick-acting in particle, middle effect, long-acting nutrient equilibrium release, fully meet crop whole breeding time to the demand of boron nutrient, fertilizer efficiency is high, remarkable in economical benefits.
Description
Technical field
The present invention relates to a kind of novel boron fertilizer, belong to fertilizer manufacture field, also relate to the manufacture method of boron fertilizer in addition.
Background technology
In the whole world, most of boron resource is distributed in the western hemisphere, the U.S., Turkey, Russia, Chile, Peru etc.Relatively centralized, China's boron rock amount of having is few, grade is low, high three deficiencies of foreign matter content.China's boron resource wretched insufficiency, cultivated soil big area boron deficiency, and field crop needs boron in a large number, and as rape, cotton, beet, fruit etc.At present, the boron fertilizer product of domestic main use mainly contains: (1) borax decahydrate, pure Boron contents is about 10.9%, is water white transparency crystallization or powder, is the most frequently used benefit boron product of China, use-pattern is that soil base is executed, also spray, its shortcoming to be the aqueous solution be alkalescence, can not with most of mixed pesticide, boron utilization ratio is low, mends effect of boron limited.(2) boric acid, boracic is acid-state, expensive, is not easily plant absorption, easily with aqueous vapor volatilization, easily runs off, easily causes and burn and boron poisoning.(3) boron magnesium mixed fertilizer, boron-containing quantity is low, poorly soluble, cannot supplement boron needed for soil and crop fast.(4) granulated boric fertilizer, by adopting sulfuric acid and borax mixed solution as binding agent, carries out granulation, obtained granulated boric fertilizer to powdery borax, boric acid powdery mixture, see patent No. CN101585720A, exist active low, easily lose, fertilizer efficiency is single, and utilization ratio is low, the shortcoming that cost is high.
Summary of the invention
The object of the invention is to overcome above-mentioned not enough problem, provide a kind of Novel multi-effect granulated boric fertilizer, boron fertilizer fertilizer efficiency meets crop whole breeding time to boron nutrient demand, and grain graininess even, and intensity is high, good fluidity, is easy to use; Another object of the present invention is to provide the manufacture method of Novel multi-effect granulated boric fertilizer, and technique is simple, easy handling.
The present invention is achieved through the following technical solutions: a kind of Novel multi-effect granulated boric fertilizer, adopt ulexite breeze, borax, boric acid, methylene urea are as pulverulent mixture material, mix by following part by weight, at 60-90 degree temperature and acidic medium condition, carry out polyreaction granulation to obtain, wherein each raw material weight number is as follows:
Ulexite breeze: 30-60
Borax: 0-40
Boric acid: 0-20
Methylene urea: 5-10
Acidic medium is one or more in the vitriol oil, phosphoric acid, citric acid.
The mixture of described raw material methylene urea to be component be MDU, dimethyl triuret, trimethylammonium four urea and tetramethyl-five urea.
The percent mass concentration of described acidic medium is 1-15%, preferably 5%.
Described raw material ulexite breeze, borax, boric acid, methylene urea all adopt particle diameter 60 order-120 order raw material.
The manufacture method of a kind of Novel multi-effect granulated boric fertilizer of the present invention, concrete manufacturing step is as follows:
The first, raw material ulexite breeze, borax, boric acid, methylene urea grinding and processing are become 60 order-120 orders, fully stirs through ulexite breeze, borax, boric acid, the methylene urea pulverized, mix to obtain mixture;
The second, one or more of getting in sulfuric acid, phosphoric acid, citric acid prepare acid medium solution, and the acidic medium strength of solution 1-15% after preparation, as granulation liquid phase;
3rd, progressively joined in granulation disc by mixture, first use a small amount of acidic medium solution impregnation, while add mixture, limit spray acidic medium solution and water vapor, keep prilling temperature 60-90 degree to carry out granulation, until particle reaches required particle diameter;
4th, carry out drying, cool, sieve obtained finished product.
In described 3rd step, prilling temperature is 80 degree.
Beneficial effect of the present invention: by under certain temperature and acidity condition, to ulexite breeze, borax, boric acid, methylene level urea, carry out polyreaction granulation, wherein methylene urea is amino many ureas (MethyleneUrea) is amino many ureas long-chain organism, there is good chemical bonding and covered effect, the boron fertilizer of different fertilizer efficiency is made well to realize polymerization, bonding, coated granulation, finished product multiple-effect granulated boric fertilizer boron nutrient is in chemical bonding effect, under polymerization and coating function, realize quick-acting, middle effect, long-acting equilibrium release, improve boron fertilizer utilising efficiency.Product discharges in conversion process in soil, methylene urea can improve soil microbial activities, promote abundant absorption and the conversion of boron nutrient, give full play to boron fertilizer fertilizer efficiency, meet crop whole breeding time to boron nutrient demand, and grain graininess even, intensity is high, good fluidity, is easy to use.Meanwhile, adopt boron ore powder as raw material, make full use of resource, reduce the production cost of boron particles, increase economic efficiency.
Product of the present invention can ensure single-dose application, continue supply boron nutrient, overcome most of boron fertilizer on market not easily to absorb, easily run off, easily cause the common disadvantage of boron poisoning, lasting effective correction crop boron deficiency, improve the boracic situation of soil, its distinctive physicochemical character make it have boron release balanced, continue long-acting feature, crop whole breeding time can be met to the needs of boron nutrient, while reducing labour cost, effectively improve the yield and quality of crop.
