Abstract
The invention provides a production method of a fertilizer for soybean with three layers of coating films. The materials of ammonium sulfate, monoammonium phosphate, potassium sulfate and free water are mixed and stirred as a mixture according to the weight proportion of 17 to 54 to 27 to 2, and water is added according 32 percent of the weight of the mixture to confect aqueous solution to be put into a granulator and atomized by compressed air; little fertilizer granules are manufactured by the granulation under drying in the hot air of 200 DEG C, and then other nutriments are coated at the little fertilizer granules to obtain the product of the invention. The invention can dissolve and release gradually according to the nutrient requirement of the soybean in different periods to ensure that the soybean is provided with different nutrition in different growth periods, which ensures the growth of the soybean and at the same time effectively improves the utilization rate of the fertilizer.
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, a large amount of fertilizer nutrients can not rational and efficient use, caused chemical fertilizer nutrient utilization ratio fertilizer low, wherein the utilization ratio of nitrogenous fertilizer has only 35%, not only fail to reach effect of increasing production, but also caused pollution environment.Especially the growth cycle of soybean is longer, and the different growing stage of knot grain has different demands to nitrogen, phosphorus, potassium and other nutrients from the germination of soybean seeds to beanpod, and the past all is to apply different fertilizer according to the soybean different growing stage.
Summary of the invention
The production method that the purpose of this invention is to provide a kind of three-layer coated soybean fertilizer, it can make fertiliser granulates form three layers of nutrient proportioning, satisfy the different demands of soybean crops 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, be the method that adopts multistage coating on master batch surface, with urea, monoammonium phosphate, vitriolate of tartar, 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. master batch manufacturing: with raw material sulphuric acid ammonium, monoammonium phosphate, vitriolate of tartar, free-water by weight 17: 54: 27: 2 are mixed into mixture, add entry by 32% of gained mixture weight, be mixed with the aqueous solution and add Fitz chilsonator, and, under 200 ℃ warm air drying, be a granulated into little fertiliser granulates by the pressurized air atomizing.
B. first step coating: above gained fertiliser granulates is added Fitz chilsonator, under the effect of cold wind, keep particle, sulphur is heated to 120 ℃, 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. second stage coating: first step gained fertiliser granulates is added Fitz chilsonator, under the effect of cold wind, keep particle at boiling state, urea is heated to 135 ℃ 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. third stage coating: second 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 26: 41: 31.4: 1.6 are mixed into mixture, add entry by 25% 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 single nutrient content of above method gained fertiliser granulates is: nitrogen: phosphorus 13%: potassium 18%: 14%; Each layer nutrient content and account for the particle weight ratio and be: outermost layer nitrogen 12%, phosphorus 18%, potassium 15%, account for 15% of particle total amount, second layer coating urea, account for 10% of particle total amount, the 3rd layer of coating sulphur, account for 5% of particle total amount, innermost layer nitrogen 11%, phosphorus 23%, potassium 13% account for 70% of particle total amount.
Product of the present invention has remedied the shortcoming of above conventional fertilizers, and after legume crop applied, at first the first layer (outermost layer) as seed manure, adopted sulfenyl fertilizer to guarantee not injure seed with the low high phosphatic manure of nitrogen.The second layer is by purity nitrogen fertilizer (urea), because behind the soybean germination, 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 is played slow releasing function (can regulate the coating thickness controlling slow release time) for the sulphur dressing.The master batch of innermost layer is a needed main nutrient of the middle and later periods of soybeans they grow, improves nutrient with high phosphorus, high potassium, low nitrogenous fertilizer material to soybean.
The present invention can be according to the required nutrient of soybean different times, and progressively dissolving discharges, and makes soybean at different growing stage, for it provides Different Nutrition, has guaranteed the growth of soybean, also effectively raises fertilizer utilization ratio simultaneously.
Embodiment
The present invention is described further below in conjunction with embodiment:
With raw material sulphuric acid ammonium, monoammonium phosphate, vitriolate of tartar, free-water by weight 17: 54: 27: 2 are mixed into mixture, add entry by 32% of gained mixture weight, be mixed with the aqueous solution and add Fitz chilsonator, and, under 200 ℃ warm air drying, be a granulated into little fertiliser granulates by the pressurized air atomizing; Above gained fertiliser granulates is added Fitz chilsonator, under the effect of cold wind, keep particle, sulphur is heated to 120 ℃, 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; First step gained fertiliser granulates is added Fitz chilsonator, under the effect of cold wind, keep particle, urea is heated to 135 ℃ of fusings, with urea atomizing ejection and be coated on the fertiliser granulates, form the urea coating by the Fitz chilsonator high pressure spray nozzle at boiling state; Second 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 26: 41: 31.4: 1.6 are mixed into mixture, add entry by 25% 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.
