Abstract
The present invention relates to a special-purpose after manuring complex mixed fertilizer for tobacco, which formed from ammonium nitrate, potassium sulfate, potassium nitrate and filling material, and is characterized by that the ratio of total weight of said composite which and the content of nitrogen and potassium oxide is 6-17%:25-41%, which can meet that the nitrate nitrogen is 50-100% of total nitrogen quantity. Its production method includes: preparing raw materials, mixing materials, feeding materials, pulverizing, screening and after-treatment. Between material-feeding and pulverizing a compacting procedure for is added.
Description
Technical field
The present invention relates to a kind of chemical fertilizer and production method thereof, definitely saying so relates to a kind of compound fertilizer and production method thereof that the plantation flue-cured tobacco is topdressed.
Background technology
At present, institute's bulk application and topdressing in Flue-cured Tobacco in China plantation is all used the compound fertilizer that contains nitrogen, phosphorus, three kinds of elements of potassium of same proportioning.Use the flue-cured tobacco of this fertiliser production, sugar degree, nicotine content are too high, and low excessively at the better-than-average tobacco leaf ratio of individual plant cigarette, cause the plantation income lower.Topdress as flue-cured tobacco if use high-quality saltpetre, then price is too high again, and tobacco company and tobacco grower can't bear economically.The first-class tobacco leaf breach of domestic and international market is bigger now, and below average tobacco leaf demand is less.Each tobacco company's below average tobacco leaf overstocks the warehouse, and the destruction loss is excessive.Particularly after the China's entry into the WTO, state's low first-class tobacco leaves of its quality high price such as cured tobacco production big country Brazil, Zimbabwe pour in China, cause serious economy loss for tobacco company and numerous tobacco growers.Therefore, improve the quality of China's flue-cured tobacco rapidly, particularly plant quality, the special use of the development high performance cheap lattice compound fertilizer that topdresses is the task of top priority.
Summary of the invention
The objective of the invention is to: solve used the problems referred to above of topdressing and existing in the present tobacco planting of China, the compound mixed fertilizer special for flue-cured tobacco top dressing of a kind of fertilizer efficiency height, price high-quality nitrogenous, potassium element low, easy to use is provided for numerous tobacco growers user.
Another object of the present invention provides a kind of production method of producing this compound mixed fertilizer special for flue-cured tobacco top dressing.
The objective of the invention is to realize by the enforcement following technical proposals: a kind of compound mixed fertilizer special for flue-cured tobacco top dressing composition, by ammonium nitrate NH
4NO
3, vitriolate of tartar K2SO and stopping composition form, it is characterized in that: in said composition, institute's weight nitrogenous, potassium oxide accounts for the percentage of composition total weight than being N:K
2O=6-17%:25-41%.
This compound mixed fertilizer special for flue-cured tobacco top dressing is made qualified product by operations such as feed proportioning, batch mixes, feeding, densification, pulverizing, screening and test packages.
The invention has the advantages that:
This compound mixed fertilizer special for flue-cured tobacco top dressing is a particulate state, and fertilising back fertilizer efficiency is difficult for loss; Its great advantage is that price is low.Show according to scientific experiment, apply topdressing of every mu of vega and need to drop into the ordinary production that purity nitrogen 2kg, pure potassium 6.8kg could guarantee flue-cured tobacco, obtain the first-class tobacco leaf of more high quality.Use special for flue-cured tobacco top dressing of the present invention only to need every mu to apply 20kg and just can guarantee the 2kg purity nitrogen of tobacco leaf demand and the pure potassium of 6.8kg, use saltpetre to topdress, its market price is 2650 yuan/ton, and use the special use of the present invention price of topdressing to be significantly less than it, save substantial contribution therefore not only for tobacco company and numerous tobacco growers, also greatly reduce the input cost of plantation flue-cured tobacco, make that the flue-cured tobacco cost of producing is low, quality is high, will strengthen the competitive power in market greatly.
Description of drawings
Fig. 1 is the production scheme of compound mixed fertilizer special for flue-cured tobacco top dressing of the present invention
Batching, batch mixing, feeding, densification, pulverizing have been provided among the figure in regular turn, screening and postprocessing working procedures.
Burden process: be with ammonium nitrate NH
4NO
3, vitriolate of tartar K
2SO
4Raw material compares N:K by the percentage of composition total weight
2The required nitrogen potassium element special use compound fertilizer that topdresses is prepared in the requirement of O=6-17%:25-41%;
Compounding process: be with by determining load weighted each component of prescription, mix with agitator;
Feeding operation: be that the formulation material that will mix is sent into the densification operation with screw feeder;
Densification operation: be the uniform mixing formulation material that to send here by screw feeder, send in the baler its densification is become piece;
Broken process: be that the caked material of densification is sent into the particle that is broken in the crusher less than below 5 millimeters;
Screening operation: with the fertilizer material grain sieve sorting below 5 millimeters;
Postprocessing working procedures: well-graded fertilizer material grain is packed after quality examination is qualified.
Embodiment
Example 1, nitrogen content are 6%, the compound mixed fertilizer special for flue-cured tobacco top dressing of potassium oxide 25%: this compound fertilizer that topdresses is made by the ammonium nitrate of weight 18Kg, the vitriolate of tartar of 50Kg and the stopping composition of 32Kg; 1450 yuan per ton of this fertilizer price, and the saltpetre market price is 2650 yuan per ton, low 1200 yuan per ton of price difference.
The compound mixed fertilizer special for flue-cured tobacco top dressing of example 2, nitrogen content 6%, potassium oxide 41%: this compound fertilizer that topdresses is made by 18kg ammonium nitrate and 82kg vitriolate of tartar; 1800 yuan per ton of this fertilizer price is than low 850 yuan of saltpetre.
The compound mixed fertilizer special for flue-cured tobacco top dressing of example 3, nitrogen content 10%, potassium oxide 35%: this compound fertilizer that topdresses is made by the ammonium nitrate of weight 30kg and the vitriolate of tartar of 70kg; 1750 yuan per ton of its fertilizer price is lower than 900 yuan of saltpetre valencys.
The compound mixed fertilizer special for flue-cured tobacco top dressing of example 4, nitrogen content 13%, potassium oxide 30%: this compound fertilizer that topdresses is made by the ammonium nitrate of weight 40kg and the vitriolate of tartar of 60kg: 1700 yuan per ton of its fertilizer price is lower than 950 yuan in saltpetre.
The compound mixed fertilizer special for flue-cured tobacco top dressing of example 5, nitrogen content 17%, potassium oxide 25%: this compound fertilizer that topdresses is made 1650 yuan per ton of its fertilizer price by the ammonium nitrate of weight 50kg and the vitriolate of tartar of 50kg, is lower than 1000 yuan in saltpetre.
