Problems solved by technology

However, ordinary BB fertilizers only contain a large number of nutrients such as N, P, and K, which cannot meet the needs of special crops for medium and trace elements.
At present, some manufacturers of nitrogen fertilizer, phosphorus fertilizer or potash fertilizer add some medium and trace elements in the production process, but the proportion of medium and trace elements in the nitrogen fertilizer, phosphorus fertilizer or potash fertilizer produced in this way is not only fixed, but also may cause the production of medium and trace elements. It has side effects with nitrogen fertilizer, phosphorus fertilizer or potassium fertilizer. In addition, when these raw materials are mixed into BB fertilizer, the content of trace elements is not targeted, and the application effect is not outstanding
[0007] At present, the existing technologies and methods have not yet overcome and solved the existing problems well.

[0040] Average compressive strength of particles: 33N; water content 2.3%: particle size (2.00-4.00mm) 95%;

[0041] Such as figure 2 As shown, weigh 10 parts of granular nitrogen fertilizer (urea), 12 parts of granular potassium fertilizer (potassium sulfate), 9 parts of granular phosphate fertilizer (first-class diammonium phosphate), and 3 parts of granular enhancer A, and mix them in a twin-shaft mixe...

Embodiment 2

[0048] Such as figure 2 As shown, weigh 10 parts of granular nitrogen fertilizer (urea), 6 parts of granular potassium fertilizer (potassium sulfate), 7 parts of granular phosphate fertilizer (first-class diammonium phosphate), and 7 parts of granular enhancer A, and mix them in a twin-shaft mixer. Measuring and packaging to obtain a function-enhanced BB fertilizer product.

[0049] The function-enhanced BB fertilizer produced by this production process contains the following mass components (in mass percentage):

[0050] Total nutrients (N+P 2 o 5 +K 2 O) 38.2%, of which N 18.5%; P 2 o 5 9.7%;K 2 O 10.0%;

[0051] Water-soluble phosphorus accounts for the percentage of available phosphorus: 85%;

[0052] Mg 2.50%; S 5.93%; Ca 2.94%; B 0.22%; Zn 0.55%; Mn 0.56%; Mo 0.09%;

[0053] The product produced in this embodiment is carried out in a paddy field cultivation test, and compared with the common BB fertilizer that only applies the same amount and the same N, P, and ...

Embodiment 3

[0055] Such as figure 1 As shown, weigh 20.0 parts of bitter soil, 3.0 parts of boron oxide, 3.0 parts of zinc oxide, 3.0 parts of manganese oxide, and 62 parts of phosphogypsum. Add an appropriate amount of process water for granulation, then send it to a tumble dryer for drying, then enter a tumble cooler for cooling, and finally sieve to obtain the enhancer B.

[0056] The enhancer contains the following components by mass (in mass percent):

[0057] Mg 10.98%; S 10.15%; Ca 12.90%; B 0.99%; Zn 2.60%; Mn 2.45%; Average compressive strength of particles: 34N;

[0058] Such as figure 2 As shown, weigh 6 parts of granular nitrogen fertilizer (urea), 6 parts of granular potassium fertilizer (potassium sulfate), 7 parts of granular phosphate fertilizer (first-class diammonium phosphate), and 5 parts of granular enhancer B, and mix them in a twin-shaft mixer. Measuring and packaging to obtain a function-enhanced BB fertilizer product.

Abstract

The invention belongs to the technical field of producing BB fertilizer in chemical fertilizer, and particularly relates to function-enhanced BB fertilizer and a production method thereof. The function-enhanced BB fertilizer comprises an enhancer and at least one of granular nitrogen fertilizer, phosphate fertilizer or potassium fertilizer. The production method includes following steps: a, preparing the enhancer: weighing salt of phosphorus or phosphogypsum, oxide and salt of magnesium or magnesia and trace element additive, mixing raw materials well, granulating, drying, cooling, and screening to obtain the enhancer; b, preparing the function-enhanced BB fertilizer: fully mixing the enhancer prepared in the step a with at least one of the granular nitrogen fertilizer, phosphate fertilizer or potassium fertilizer to obtain the function-enhanced BB fertilizer. The enhancer is added into chemical fertilizer raw materials, so that the BB fertilizer produced by the method has high nutritional value for plants.

Description

technical field [0001] The invention belongs to the technical field of BB fertilizer production in chemical fertilizers, and in particular relates to a function-enhanced BB fertilizer and a production method thereof. Background technique [0002] Elements with a content of 0.1% to 0.5% in plants are called secondary elements. The contents of calcium, magnesium and sulfur in plants are 0.5%, 0.2% and 0.1% respectively, so they are listed as medium elements. The trace elements necessary for crop growth include zinc, boron and manganese , molybdenum, copper, iron, chlorine and other 7 kinds. [0003] The growth and development of crops need to absorb various nutrients, but what determines the crop yield is the effective plant growth factor with the smallest relative content in the soil, and the yield will change accordingly within a certain limit with the increase or decrease of this factor. Because of this limiting factor, it is difficult to increase the yield of crops even ...
