Abstract
The invention discloses a method for producing tobacco special fertilizer, and belongs to the field of composite fertilizer. The fertilizer is composed of the following components in percentage by weight: 46% of urea, 6% of monoammonium phosphate with a content of 52%, 54 to 56% of potassium sulfate with a content of 50%, 1% of amino acid chelated trace element, 1% of humic acid chelated trace element, and 10% of sulphur, and is prepared by the following steps: grinding the raw materials mentioned above, granulating the mixture, and finally painting sulphur on the granules so as to obtain the finished product. The product is a tobacco special fertilizer having strong specificity, has the advantages of comprehensive nutrients and stable, lasting, and sustain-released fertilizing effect, and is suitable for tobacco in each growth period, especially in the middle period of the growth process.
Description
Technical field:
Product of the present invention belongs to Agricultural Fertilizer field, relates in particular to a kind of method of producing fertilizer special for tobacco.
Background technology:
Tobacco is Solanaceae annual herb plant, for the manufacture of cigarette and pipe tobacco, there are safflower tobacco and a small part Folium Nicotianae rusticae, China plantation tobacco, mainly with farm manure and cake fertilizer, be main in the past, because various nutrition in farm manure and cake fertilizer is comparatively complete, the nutrient that cigarette strain absorbs is balance comparatively, tobacco physiological disease is rare, obtain applying more widely always, but its shortcoming is nutrient content and the bad regulation and control of release in farm manure and cake fertilizer, tend to occur remaining green when it is due to become yellow and ripe late-maturing or cross the phenomenon of caducous Huang, cause tobacco production and value amount unstable, the cigarette product quality of producing be can not enter class.Along with scientific and technical development, there is essence variation in tobacco fertilizer structure and fertilizer practice, and chemical fertilizer particularly fertilizer special for tobacco is widely applied on plantation tobacco.Stable content and release just because of chemical fertilizer are more regular, and tobacco production and value amount is just comparatively stable, and fertilising benefit is significantly improved.Different crops is due to the difference in genotype and physiological metabolism, they to nitrogen phosphorus potassium and wherein the demand of trace element be different, because the nutrient demand difference of Different Crop is often larger, therefore, in formula, must first take in.With regard to tobacco, nutrition absorption amount has been compared bigger difference with other crop, and to the demand of npk nutrient ratio, is also different at different growth periods.For nitrogen, tobacco is less to the demand of phosphorus, and in the time of infertility, the N∶P ratio consuming changes also little, the required nitrogen of tobacco: phosphorus: the ratio of potassium is 1:0.2:2.Fertilizer special for tobacco is by its production and the technique that is mixed, be broadly divided into slurry process granule type composite fertilizer, Liao Xing composite fertilizer of dry powder body corporate and mix type Chemical Mixed Fertilizer three major types in bulk, the present invention is Liao Xing composite fertilizer of dry powder body corporate with slow-release function, in its production process, add is that to take urea, monoammonium phosphate, potassium sulfate be main raw material, in fertilizer, add in addition trace element, trace element not only can supplement the nutritional deficiency in tobacco, to improving nitrogen and potassium utilization rate, also has certain effect.
Summary of the invention:
The problem that the present invention mainly solves is to provide a kind of method of producing fertilizer special for tobacco in batches, this product is the extremely strong tobacco composite fertilizer special of a kind of specific aim, there is production technique simple, product nutrient is complete, fertilizer efficiency is stablized lasting slowly-releasing, is generally applicable to the especially suitable use of each stage of tobacco growing in the mid-term of tobacco growing.The raw material of producing this product use has: content is that monoammonium phosphate 6%, the content that 46% urea 26-28%, content are 52% is 50% potassium sulfate 54-56%, aminoacid chelating microelement 1%, humic acid chelating trace element 1%, sulphur 10%.
The present invention can be achieved through the following technical solutions:
Produce a method for fertilizer special for tobacco, it is characterized in that being formed by following steps:
(1) by the content of formula ratio, be that monoammonium phosphate, content that 46% urea, content are 52% are that 50% potassium sulfate, aminoacid chelating microelement, humic acid chelating trace element are sent into pulverizer and pulverized as Powdered, then mixed powder sent into tablets press and carried out obtaining compound fertilizer granules after granulation.
(2) sulphur of formula ratio is sent into sulphur is sent into sulphur melting tank, adjusting temperature in tank is 148 ℃-152 ℃, and after 0.5 hour, sulphur becomes molten state, immediately the sulphur of molten state is sent into pressure-pot, and adjusting tank internal pressure is 7-10Mpa.
(3) sending into after compound fertilizer granules preheating is coated with to sulphur rotary drum and compound fertilizer granules particle is rotated with rotary drum, immediately the melting sulphur in pressure-pot is uniformly sprayed on compound fertilizer granules by a plurality of hydraulic efficiency pressure nozzles, its coating thickness is about 20-25 micron, obtain being coated with sulphur compound fertilizer granules, after naturally drying, obtain finished product.
Aminoacid chelating microelement described in above-mentioned steps (1) is comprised of iron-amino acid chelate, amino acid chela copper, chelating amino acids boron; Described humic acid chelating trace element is comprised of humic acid chelating zinc, humic acid chelating magnesium, humic acid chelating calcium.
Temperature in sulphur melting tank described in above-mentioned steps (2) is 150 ℃.
The invention has the beneficial effects as follows: a kind of method of producing fertilizer special for tobacco is provided, the method has that technique is simple, reaction conditions is gentle, without advantages such as sewage exhaust gas emissions, product nutrient is complete, fertilizer efficiency is stablized lasting slowly-releasing, is generally applicable to the especially suitable use of each stage of tobacco growing in the mid-term of tobacco growing.
