Abstract
The invention discloses a production method of multilayer nutrient fertilizer, relating to a production method of a fertilizer which can promote the growth of crops. A multi-stage coating method is adopted on the surface of master batch. Urea, monoammonium phosphate, potassium chloride, potassium sulfate, ammonium chloride and ammonium sulfate are taken as main raw materials and are coated on the surface of the master batch after being compounded by different proportions, thus leading each layer of the master batch to be the multilayer nutrient fertilizer with different nutrients. The invention can be dissolved and released gradually according to nutrition needed by crops in different periods, so the invention provides different nutritionts for the crops in different growth periods, thus guaranteeing the growth of the crops and effectively improving the utilization ratio of the fertilizer as well.
Description
Affiliated technical field
The present invention relates to the agricultural planting industry, refer more particularly to a kind of production method that promotes the fertilizer of crop growth.
Background technology
In the process of growth of farm crop, need use chemical fertilizer and promote its growth.And the nutrient content proportioning that present common complex fertilizer product particle all is homogeneous from inside to outside.Npk nutrient when using in the particle can not discharge according to the different demands of crop different growing stages to nutrient, and a large amount of fertilizer nutrients can not rational and efficient use, has caused chemical fertilizer nutrient utilization ratio fertilizer low.Especially the utilization ratio of nitrogenous fertilizer has only 35%, not only fails to reach effect of increasing production, but also has caused the pollution to environment.For thoroughly changing this situation, must change the pattern of the extensive processing of fertiliser production, adopt new and high technology, fertilizer processing is become more meticulous, not only improve utilization rate of fertilizer but also reach the purpose that crop yield increases income, this also improves the ecological environment, and walks the inevitable requirement of sustainable development path.
Summary of the invention
The production method that the purpose of this invention is to provide a kind of multilayer nutrient fertilizer, it can make fertiliser granulates form the multilayer nutrient proportioning, satisfy the different demands of crop different growing stages to nitrogen, phosphorus, potassium nutrition, reach the raising utilization rate of fertilizer, alleviate the environmental pollution that fertilizer loss causes, improve the quality of farm crop.
For achieving the above object, the present invention is achieved in that
A kind of production method of repeatedly nutrient fertilizer, it is the method that adopts multistage coating on the master batch surface, with urea, monoammonium phosphate, Repone K, vitriolate of tartar, ammonium chloride, sulfate of ammoniac as main raw material, in being coated to the master batch surface after the different ratio proportionings, make it become every layer of multilayer nutrient fertilizer that contains Different Nutrients
The concrete complete processing that is adopted is:
A. the first step (innermost layer) coating: with raw material sulphuric acid ammonium, monoammonium phosphate, vitriolate of tartar, free-water by weight 10-20: 45-60: 20-35: 1-2 is mixed into mixture, add entry by 30% of gained mixture weight, be mixed with the aqueous solution and add Fitz chilsonator, and, under 200 ℃ warm air drying, carry out granulation and be applied as little fertiliser granulates by the pressurized air atomizing.
B. second stage coating: first step gained fertiliser granulates is added Fitz chilsonator, under the effect of cold wind, keep particle, sulphur is heated to 115 ℃, with sulphur atomizing ejection and be coated on the fertiliser granulates, form the sulphur coating by the Fitz chilsonator high pressure spray nozzle at boiling state.
C. third stage coating: second stage gained fertiliser granulates is added Fitz chilsonator, under the effect of cold wind, keep particle at boiling state, urea is heated to 130 ℃ of fusings, with urea atomizing ejection and be coated on the fertiliser granulates, forms the urea coating by the Fitz chilsonator high pressure spray nozzle.
D. fourth stage coating: third stage gained fertiliser granulates is added Fitz chilsonator, under 200 ℃ hot blast effect, keep particle at boiling state, with raw material sulphuric acid ammonium, monoammonium phosphate, vitriolate of tartar, free-water by weight 20-30: 35-45: 30-35: 1-2 is mixed into mixture, add entry by 30% of gained mixture weight, be mixed with the aqueous solution and add Fitz chilsonator, with aqueous solution atomizing ejection and be coated on the fertiliser granulates, obtain the finished product fertiliser granulates by the Fitz chilsonator high pressure spray nozzle.
The above method gained fertiliser granulates shared weight ratio of each layer from outside to inside is 14-16: 8-15: 4-6: 65-75.
The conventional fertilizers particle all is a granulating and forming, all be fixed npk nutrient content proportioning from inside to outside, in each period of plant growth all is to supply with nutrient according to this fixed proportion, product of the present invention has remedied the shortcoming of above conventional fertilizers, after farm crop apply, at first the first layer (outermost layer) as seed manure, adopts sulfenyl fertilizer to guarantee not injure seed with the low high phosphatic manure of nitrogen; The second layer is purity nitrogen fertilizer (urea), because after farm crop germinate, the root nodule maturation of not growing needs to replenish the nitrogen nutrient, cooperates the P-K fertilizer of the first layer, guarantees the development growth in seedling stage; The 3rd layer for the sulphur dressing plays slow releasing function, can regulate the coating thickness controlling slow release time; The 4th layer is the needed main nutrient of middle and later periods of crop growth, improves nutrient with high phosphorus, high potassium, low nitrogenous fertilizer material to farm crop.
The present invention can be according to the required nutrient of farm crop different times, and progressively dissolving discharges, and makes farm crop at different growing stage, for it provides Different Nutrition, has guaranteed the growth of farm crop, also effectively raises fertilizer utilization ratio simultaneously.
