Description
Technical field
The present invention relates to a kind of tomato long-acting special slow-release fertilizer, the invention still further relates to the preparation method of this tomato long-acting special slow-release fertilizer.
Background technology
Tomato is less in growth fertilizer requirement in early stage, Sheng phase fertilizer requirement is increased sharply; By required various fertilizer, it stresses nitrogenous fertilizer in growth early stage, and the later stage stresses potash fertilizer, and phosphate fertilizer is implemented vegetative period all the time; Using common fertilizer need repeatedly topdress in tomato growth stage, and can not well satisfy the fertile characteristic of these need of tomato.The fertilizer that therefore need provide a kind of not needs that are fit to its growth characteristics to topdress.A kind of long-acting complex fertilizer additive is disclosed among the one Chinese patent application prospectus CN1163449A; Use this long-acting complex fertilizer additive fertilizer efficiency period and can extend to 90-120 days, the present invention provides a kind of tomato long-acting special slow-release fertilizer of suitable tomato growth on the basis of using this long-acting complex fertilizer additive.
Summary of the invention
The present invention provides a kind of tomato long-acting special slow-release fertilizer, and this tomato long-acting special slow-release fertilizer can satisfy tomato in the demand of each growth period to fertilizer; For this reason, the present invention also provides the preparation method of this tomato long-acting special slow-release fertilizer.
The present invention provides a kind of tomato long-acting special slow-release fertilizer to achieve these goals; Said tomato long-acting special slow-release fertilizer contains the component of following mass fraction: 230 parts of nitrogenous fertilizer effective constituents; 120 parts of phosphate fertilizer effective constituents; 100 parts of potash fertilizer effective constituents, wilkinite 92-100 part, long-acting complex fertilizer additive 7-9 part;
Wherein, contain the smectite that mass percent is 85-90% in the said wilkinite, the mass fraction of each component is in the said long-acting complex fertilizer additive: 2-8 part quinhydrones, 3-25 part Dyhard RU 100,0.1-0.8 part complex rare-earth, 70-95 part zeolite powder.
Preferably, said tomato long-acting special slow-release fertilizer is made up of each component of following mass fraction:
273 parts of monoammonium phosphates, vitriolate of tartar 190-196 part, urea 429-431 part, wilkinite 92-100 part, long-acting complex fertilizer additive 7-9 part;
Wherein: in the monoammonium phosphate mass percent of N element be 11%, P
2O
5Mass percent be 44%, K in the vitriolate of tartar
2The mass percent of O is more than or equal to 51%, and the mass percent of N element is more than or equal to 46.4% in the urea.
Preferably, said tomato long-acting special slow-release fertilizer is made up of each component of following mass ratio: monoammonium phosphate: vitriolate of tartar: urea: wilkinite: long-acting complex fertilizer additive=273:196:431:92:8;
Wherein: in the monoammonium phosphate mass percent of N element be 11%, P
2O
5Mass percent be 44%, K in the vitriolate of tartar
2The mass percent of O is 51%, and the mass percent of N element is 46.4% in the urea.
The present invention also provides the preparation method of this tomato long-acting special slow-release fertilizer; Said preparing method's step is following: each component of tomato long-acting special slow-release fertilizer is mixed back fragmentation, granulation, oven dry, cooling, screening, coating by proportioning, make tomato long-acting special slow-release fertilizer.
The beneficial effect that the technical scheme that the embodiment of the invention provides is brought is:
1, contains long-acting complex fertilizer additive in the tomato long-acting special slow-release fertilizer of the present invention, make the fertilizer efficiency period of tomato long-acting special slow-release fertilizer extend to 110-130 days, in the process of growth of tomato, can topdress.Tomato long-acting special slow-release fertilizer of the present invention is well positioned to meet the requirement that tomato fertilizer requirement in early stage is few, contain phase fertilizer requirement surge; Satisfy tomato growth early stage to the demand of nitrogenous fertilizer, growth later stage to the demand of potash fertilizer and whole growing demand to phosphate fertilizer; Thereby make crop yield improve 20%, the haw rate of tomato also is significantly improved.
2, tomato long-acting special slow-release fertilizer of the present invention adopts the control technique of nitrogen transformation and the technical system that the phosphorus activating technology combines, and the nutrient supply of the tomato long-acting special slow-release fertilizer of processing is coordinated with the fertilizer requirement for crop growth rule mutually, has improved plant recovery of nutrient.When applying the composite fertilizer of common nutrients such as contrast by the traditional fertilization method, nitrogen use efficiency is 28.6%-36.37%, use tomato long-acting special slow-release fertilizer of the present invention after, nitrogen use efficiency is 38.7%-43.7%, has improved 2.33%-15.1%; Phosphorus utilization on average improves 4 percentage points, reaches 19-28%.Under the situation that obtains identical output, the fertile phosphorus nutrient of tomato long-acting special of the present invention consumption reduces 1/3.
3, organize in the total nutrient amount at 80% o'clock for nutrient fertilisings such as contrasts, tomato long-acting special slow-release fertilizer of the present invention is still compared photograph and is waited nutrient group raising the output 8.19%, and tomato long-acting special slow-release fertilizer of the present invention exempts to topdress, the saving of labor.Therefore tomato long-acting special slow-release fertilizer of the present invention has reduced the input cost of producing.
4, tomato long-acting special slow-release fertilizer of the present invention is to people and animals and farm crop safety; Less residue in soil and farm crop; Degradation rate reaches 75% then, residual quantity 0.071mg/kg in the soil, low 1400 times of the 100mg/kg of brake specific exhaust emission level of environment achievement (DMEG) standard.The nitrogen amount of drenching reduces 48%, N after using tomato long-acting special slow-release fertilizer of the present invention
2The O quantity discharged reduces by 53%, can significantly reduce nitrogenous fertilizer and use the environmental pollution that brings; Simultaneously, improve the quality of crop, especially reduced nitrate content in the crop, helped human health.
