Abstract
The invention relates to a medical stone bio-fertilizer and a preparation method thereof. The method comprises the following steps of: grinding 40-42 parts of medical stone, 1-2 parts of beneficial bacteria, 10-20 parts of urea, 10-20 parts of calcium magnesium phosphate, 3-8 parts of potassium chloride, 30-40 parts of double superphosphate and 10-15 parts of bentonite serving as a pelletizing accelerator respectively; and uniformly mixing, pelleting, drying and blending to obtain the bio-fertilizer. The fertilizer which takes the medical stone as a main raw material is rich in a plurality of elements such as nitrogen, phosphorus, potassium, manganese, zinc, molybdenum, silicon and the like which are needed by the growth of plants, so that the yields and the qualities of crops can be enhanced, fertilizers and pesticides remaining in soil can be adsorbed and decomposed, and soil can be effectively improved.
Description
Technical field
The present invention relates to a kind of medical stone biological fertilizer and preparation method thereof.
Background technology
At present, the phenomenon of blindly applying fertilizer in the national agriculture production is quite serious.Chemical fertilizer utilization ratio only has 30%, uses fertile unreasonable structure in addition, and 1 year nearly 2,000 ten thousand tons of nitrogenous fertilizer that will run off is equivalent to the output of 100 middle-size and small-size nitrogen fertilizer plants.This has not only increased agriculture production cost, causes benefit low, and quality of agricultural product is descended, and ploughing, it is also more and more serious to degenerate.Address these problems, effective means is that to use with the medical stone be the composite fertilizer of main material production.
Medical stone is a kind of multielement ore.Scientific experiment and facts have proved in a large number, it is not only to the human body beneficial, and can use on the farm crop and in the soil improvement.According to detection, medical stone multielement natural mineral fertilizer is rich in elements such as the required calcium of crop growth, sulphur, iron, boron, manganese, zinc, molybdenum, silicon, suitably adds nitrogen, phosphorus, potassium again, is exactly efficient, the nontoxic active fertilizer of ideal.It can chessom, improve Soil structure, the strong sprout of keeping a full stand of seedings, cold-resistantly anti-ly freeze, lodging-prevention, prevent the quality of chemical fertilizer residual in early ageing, absorption and the decomposition soil and agricultural chemicals, raising agricultural-food, the immunological competence of enhancing crop, also can effectively restrain disease and pest takes place, and kill weeds selectively, can be widely used in farm crop, fruit tree and the vegetables production.
Summary of the invention
First purpose of the present invention provides the high medical stone biological fertilizer of a kind of medical stone content.
Second purpose of the present invention provides the preparation method of this medical stone biological fertilizer.
For first purpose that realizes inventing, the medical stone biological fertilizer that is provided, comprise with medical stone, probiotics, urea, fused(calcium magnesium)phosphate, Repone K, double superhosphate and granulation promotor wilkinite, behind separated pulverizing, according to ratio of weight and number is medical stone: probiotics: the ratio of urea, fused(calcium magnesium)phosphate: Repone K: double superhosphate: wilkinite=40-42: 1-2: 10-20: 10-20: 3-8: 30-40: 10-15, successively through pulverizing, uniform mixing, granulation, dry, being mixed makes.This medical stone biological fertilizer contains medical stone, 1%-2% probiotics, 10-20 nitrogen, the Vanadium Pentoxide in FLAKES of 10%-20% and the potassium oxide of 1%-2% of 30%-40%.
Be to increase medical stone biological fertilizer particulate intensity, weight part also is provided is 1 carboxymethyl cellulose in the proportioning raw materials of the medical stone biological fertilizer that is provided through pulverizing.
For second purpose that realizes inventing, the preparation method of the medical stone biological fertilizer that is provided comprises the steps: successively
A, pulverizing: be respectively that 80 orders-100 purpose fused(calcium magnesium)phosphate, Repone K, double superhosphate, wilkinite and carboxymethyl cellulose are crushed to 100 orders-120 order with medical stone, urea, granularity;
B, mixing: according to ratio of weight and number is medical stone: the medical stone after the ratio of urea, fused(calcium magnesium)phosphate: Repone K: double superhosphate: wilkinite: carboxymethyl cellulose=40-42: 1-2: 10-20: 10-20: 3-8: 30-40: 10-15: 1-2 will be pulverized, urea, fused(calcium magnesium)phosphate, Repone K, double superhosphate, wilkinite and carboxymethyl cellulose uniform mixing form powder mix;
C, granulation: earlier powder mix is sent into revolving drum granulator, it is the 0.5mm-1mm master batch that powder mix formation granularity above 50% is arranged in revolving drum granulator, again this master batch and the remaining powder that is mixed are sent into the one-level granulating disc that has sprinkler head, water evenly is sprayed on master batch and the remaining powder that is mixed, forming granularity is the particle of 1.5mm-5.0mm, these particles improve its hardness through second granulating disc, form reinforcing particle;
D, first drying: with the reinforcing particle temperature is 200 ℃-230 ℃ rotary drum dryer oven dry 2 minutes-3 minutes, and making the water content of reinforcing particle is 18%-25%, makes work in-process;
E, screening: work in-process are sieved for twice, the screen-aperture that sieves for the first time is 2mm, filter out granularity and deliver to the B step less than the small-particle of 2mm, the screen-aperture that sieves for the second time is 4.2mm, filter out granularity and deliver to the B step after crushed greater than the macrobead of 4.2mm, remaining particle is the screening particle;
F, secondary drying: will screening particle, to send into temperature be 250 ℃-280 ℃ sulfuration bed, dried 20 seconds-60 seconds, makes water content and be not higher than 3% medical stone biological fertilizer particle.
G, be mixed: the medical stone biological fertilizer particle that cools the temperature to normal room temperature is sent in the mixing and blending machine and in proportion 1-2% probiotics powder is poured in the mixing and blending machine, evenly stirred 2 minutes, make probiotics evenly be adsorbed on the medical stone biological fertilizer particle surface medical stone biological fertilizer of system.
Medical stone biological fertilizer provided by the present invention not only contains the needed nitrogen of crop growth, phosphorus, potassium three big elements but also has increased probiotics, and wherein medical stone content is up to 40%-42%.Use that medical stone biological fertilizer can effectively overcome at long-term application chemical fertilizer, agricultural chemicals and drawback such as the soil property that causes hardens, polluted underground water resource.Can play expanded soil, releasing is hardened, strong sprout fruit retention; Waterlogging, cold-resistant anti-the freezing of drought resisting; Lodging-prevention, anti-early ageing improve corps nutrient and are worth, and can reduce rate of fertilizer application effectively, have reduced planting cost.Use medical stone biological fertilizer provided by the present invention, not only can improve the output of farm crop, and can promote its quality, as wheat increase yield 10%-15%, increasing production of rice 10%-25%, peanut yield increasing 10%-35%, corn yield increasing 15%-19%, cotton volume increase 10%-15%, melon and fruit is fragrant and sweet and stature is even.Adopted twice oven dry among the preparation method, compared, improved production efficiency with traditional first drying.
