Abstract

The invention discloses a production method for a tobacco-specific fertilizer. The product of the invention is a special fertilizer targeted for tobacco. The fertilizer is technically prepared according to characteristics of growing tobacco, wherein the ratio of nitrogen to phosphor to potassium is 1:0.15:2, and nitrogen and potassium have a large proportion while phosphor has a small proportion. A proper amount of trace elements are added, which enables the utilization rate of the nitrogenous fertilizer and the potash fertilizer to be improved. Since the chemical fertilizers have stable content and release regularly, the quality of tobacco leaves is stable and fertilizing effects are substantially enhanced. The raw materials used in the preparation of the tobacco-specific fertilizer comprise, by weight, 49% of phosphoric acid for industrial use, 98% of liquefied ammonia, 46% of urea, 50% of potassium sulfate, a bioactivator and borax.

Description

A kind of production method of fertilizer special for tobacco

Affiliated technical field:

Product of the present invention belongs to agricultural fertile field.

Background technology:

China plantation tobacco, many based on farm manure and cake fertilizer before 30 years, because various nutrition are comparatively complete in farm manure and the cake fertilizer, the nutrient that the cigarette strain absorbs is balance comparatively, and the tobacco physiological disease is rare, obtains using more widely always.But its shortcoming is a nutrient content and discharge bad regulation and control in farm manure and the cake fertilizer, tends to occur remaining green when it is due to become yellow and ripe late-maturing or cross the phenomenon of caducous Huang, causes tobacco production and value amount instability, and the cigarette product quality of producing be can not enter class.Along with the continuous expansion of China's chemical fertilizers production ability, the essence variation has taken place in tobacco fertilizer structure and fertilizer practice, and chemical fertilizer particularly fertilizer special for tobacco has obtained widespread use on tobacco.Stable content and release just because of chemical fertilizer are more regular, and the tobacco production and value amount is just comparatively stable, and the fertilising benefit is significantly improved.Fertilizer special for tobacco is broadly divided into slurry process granule type composite fertilizer, the fertile three major types of dry powder body corporate material type compound mix type compound fertile and in bulk by its production and the technology that is mixed.The present invention refers to slurry process granule type composite fertilizer.Producing the special-purpose fertile the first step of this type is to produce phosphor ammonium slurry, phosphoric acid is the main raw material of producing phosphor ammonium slurry, phosphoric acid and ammonia react generate ammonium phosphate, because of in the time solution the pH value different, can generate three kinds of different phosphate hydrochlorates, be monoammonium phosphate NH4H2PO4, diammonium phosphate (NH4) 2HPO4 and triammonium phosphate (NH4) 3PO4.Monoammonium phosphate is stable existence in acidic solution, and diammonium phosphate is stable in basic solution, and triammonium phosphate must be present in the strong alkali solution, easily decomposes under normal temperature, normal pressure.So have only monoammonium phosphate and diammonium phosphate to can be used as fertilizer.Its nitrogen of monoammonium phosphate made from the medium phosphoric acid by wet process of foreign matter content: phosphorus: potassium content is 18: 46: 0, and the N-P-K content of diammonium phosphate is 11: 55: 0.And the commodity ammonium phosphate that as fertilizer sources the is used mixture of monoammonium phosphate and diammonium phosphate often, thereby its nitrogen content and phosphorus content often fall between, and the monoammonium phosphate of slurry process production contains N:10～11%, contains P2O5:40～44%.In phosphoric acid and ammonia and the time, also can add other acid, as sulfuric acid, nitric acid etc., produce products such as ammonium phoaphate-sulfate or ammonium phosphate-nitrate.No matter be ammonium phoaphate-sulfate or nitrophosphate fertilizer, all be the compound manure of two yuan in nitrogen, phosphorus.In its production process, add vitriolate of tartar, promptly become the ternary fertilizer special for tobacco.This class fertilizer special for tobacco, general nutrient content is more even.Different crops is because the difference in genotype and the physiological metabolism, they to nitrogen phosphorus potassium and in other demand of trace element be different, owing to the nutrient demand difference of Different Crop is often bigger, therefore, in prescription, must at first take in.With regard to tobacco, the nutrition absorption amount has been compared than big difference with other crop.Not only Different Crop is to the demand percentage difference of nitrogen phosphorus potassium, even with a kind of crop, it also is different at different growth periods to the demand of npk nutrient ratio.For nitrogen, tobacco is less to the demand of phosphorus, and in the time of infertility, the N/P ratio example that is consumed changes also little.Therefore, if wish to obtain the best fertilizer of effect, the base manure of tobacco and the difference to some extent of topdressing on nitrogen phosphorus potassium proportioning.The required nitrogen of tobacco: phosphorus: the ratio of potassium is 1: 0.15: 2.Adding boron in addition in fertilizer, is effective to improving nitrogen and potassium utilization rate.On the soil of boron deficiency, add 0.5% borax in the flue-cured tobacco fertilizer formula, can improve potassium utilization rate 8～15%; Lack on the soil of chlorine, add 3% chlorion, can improve utilization rate of nitrogen fertilizer 4～9%, but might cause quality of tobacco to descend, the cigarette of making cuts fire easily, will note during interpolation.

Summary of the invention:

The problem that the present invention mainly solves provides a kind of method of suitability for industrialized production fertilizer special for tobacco, this product is the extremely strong tobacco composite fertilizer special of a kind of specific aim, this production technique for fertilizer is simple, and nutrient is complete, effect is neat, fertilizer efficiency is stable lasting, generally is applicable to each stage of tobacco growing.Producing the raw material that this product uses has: content is that 49% 0 part of industrial phosphatase 11, content are that 98% 5 parts in liquefied ammonia, content are that 29 parts in 46% urea, content are 60 parts of 50% vitriolate of tartar, 1.5 parts of biologically active agents, 0.5 part of borax.

A kind of production method of fertilizer special for tobacco, its beneficial effect is: technology is simple, and cost is low, and fertilizer efficiency is good, is suitable for suitability for industrialized production, is specifically designed to the fertilising of tobacco.

Embodiment:

Embodiment 1:
