Description
Technical field
The present invention relates to technical field of fertilizers, more particularly to a kind of special fertilizer for tobacco and preparation method thereof.
Background technology
Flue-cured tobacco (FluecuredTobacco) is also known as fire tube flue-cured tobacco, comes from the Virginia in the U.S., has special shape
State feature, thus also referred to as Virginia type.Flue-cured tobacco is that China is also the tobacco type that cultivated area is maximum in the world, is volume
The primary raw material of cigarette industry, is also made for pipe tobacco, tobacco planting industry, as time saving and energy saving, economic benefit gain quick return and it is reliable
Industry that " short, adaptable and fast " is popular, justify the vast many rural areas in China, all suitable planting and development in width, be especially located in inland, sea
Extremely deficient motherland's Antarctica side --- the nation mountain area in Yunnan Province of land sky transportation condition, practice have shown that " it has become
Sustainable development industry that numerous tobacco growers are willing to accept ", " three for consolidating and revitalizing the poor national place in vast side
Agriculture " is economical, optimizes its social-economic formation, has played obvious function and has acted on visible.
Flue-cured tobacco is that China is also the tobacco type that cultivated area is maximum in the world, is the primary raw material of cigarette industry, at me
The planting area of state-owned large area, but flue-cured tobacco is very sensitive to nutrient, at present, people typically adopt when to Fertilizer Application of Tobacco
Flue-cured tobacco top dressing is given with raw materials such as chemical fertilizer, urea, human excrement, although there is certain effect, contained nutrition in chemical fertilizer, urea
It much can not meet the nutritional need of flue-cured tobacco, easily cause that flue-cured tobacco blade face is small, and premunition is poor because lacking nutrition, various disease pests easily occur
Evil, yield do not increase, therefore how to improve these problems to reach the growth of promotion flue-cured tobacco, improve the yield of flue-cured tobacco, improve roasting
The purpose of the quality of cigarette, it is the emphasis studied at present.
The content of the invention
The present invention is in order to solve the above technical problems, provide a kind of special fertilizer for tobacco and preparation method thereof.
Realized particular by following technical scheme：
A kind of special fertilizer for tobacco, including following raw material by weight：Potassium sulfate 30~40, potassium dihydrogen phosphate 10~

0.6~0.8：0.3~0.5 mass ratio mixing.
Described compound amino acid, it is by 1~2 by leucine, methionine, threonine and tryptophan：0.5~0.8：0.1
~0.3：0.8~1.2 mass ratio mixing.
Described special fertilizer for tobacco, its particle diameter are 0.4~0.6mm.
The potassium sulfate uses the potassium sulfate containing K2O >=50%, and the potassium dihydrogen phosphate is contained using K2O >=28% is contained
The potassium dihydrogen phosphate of the grade of P2O5 >=22%, calcium magnesium phosphate using containing P2O5 >=15% grade calcium magnesium phosphate, with weight hundred
Divide content meter.
The preparation method of the special fertilizer for tobacco, comprises the following steps：
(1) organic fertilizer is prepared：Cattle and sheep excrement, biogas residue, rape cake, furfural dregs, tea grounds and mushroom residue are weighed by formula ratio mixed
Close, crush, the zymotic fluid of 30~40% amounts of the crushed material quality is uniformly sprayed on crushed material, and in the mixture
Upper bedding plastic sheeting, ferment 4~5d, obtains organic fertilizer；
(2) inorganic fertilizer is prepared：Potassium sulfate, potassium dihydrogen phosphate, calcium magnesium phosphate, compound trace element fertilizer are weighed by formula ratio, mixed,
The water of 0.6~0.8 times of the mixture is added, is dissolved by heating, cool drying, crushes and inorganic fertilizer is made；
(3) batch mixing：Organic fertilizer, inorganic fertilizer are mixed, is crushed, is added compound bacteria, compound amino acid, mix thoroughly, is granulated, i.e.,
Obtain special fertilizer for tobacco.
Described zymotic fluid, it is by 0.3~0.5 by Lactobacillus plantarum, deinsectization streptomycete and saccharomyces cerevisiae：0.4~0.6：
0.1~0.2 mass ratio mixing, tempers into the solution that content is 30~40%.
Described fermentation, fermentation temperature are 38.5~42.5 DEG C.
In summary, the beneficial effects of the present invention are：The fertilizer of the present invention, has significant effect of increasing production to flue-cured tobacco,
The raw material sources of flue-cured tobacco fertilizer of the present invention are extensive, and preparation method is simple, and cost is low, with strong points, and this dedicated fertilizer contains roasting
A variety of a great number of elements and micronutrient element necessary to cigarette, rich in multiple elements such as the nitrogen required for tobacco growth, phosphorus, potassium, boron,
Growing and high-quality, high yield needs for flue-cured tobacco different times is adequately met, simultaneously effective improves soil texture,
Utilization rate of fertilizer is substantially increased, fertilizer application frequency is reduced, slows down excessive fertilization and injured to caused by soil；Through using result of the test
It has been shown that, after fertilizer application flue-cured tobacco of the present invention, per mu yield (dry cigarette) is up to more than 150kg, and Flue-cured tobacco Quality significantly improves.
