Description
Technical field
The present invention relates to the auxiliary agent used by fertilizer production, for fertilizer auxiliary agent technical field, be specifically related to a kind of upgrading routine
Fertilizer is the auxiliary agent containing secondary and micro-element fertilizers and preparation method.
Background technology
China is a large agricultural country, and various fertilizer, especially chemical fertilizer play indelible tribute to China's grain security
Offer.
In past 20 years, Grain in China realizes rising year by year, but quality of agricultural product declines the most year by year, and nearly 5 years grain is total
Increase of production speed is decreased obviously, and traces it to its cause, and the agricultural experts of China, chemical fertilizer expert, plantation expert, soil expert unanimously recognize
For, causing agricultural output increase to slow down, and the reason that grain quality declines is, soil nutrient is lacked of proper care, and current agricultural is undue
Rely on a great number of elements nitrogen, phosphorus, potassium, but ignore the synergistic function to a great number of elements of middle trace element and to crop life
The facilitation of long metabolism.Therefore soil and the crop of China is badly in need of supplementing middle trace element, needs containing middle trace element
Compound fertilizer or the new-type fertilizer such as simple substance fertile (carbamide, phosphate fertilizer, potash fertilizer).
The demand of grain drives the explosive growth of China's chemical fertilizer, past 10 years, Chinese all kinds of fertilizer enterprises up to 6000
Many families, but product mostly is tradition nitrogen, phosphorus, potassium straight fertilizer or compound fertilizer.China's Fertilizer Market homogeneity competition, price
War, the big and small fertilizer enterprises closed down for only 2 years is more than 500, and some larger fertilizer enterprises are also losss
Seriously, frequency faces verge of bankruptcy.
But, the annual external fertilizer of import of China rises the most year by year, price being combined far above Chinese identical NPK nutrient
Fertilizer, reason is the effective of import fertilizer, and it is few to plant out diseases and pests of agronomic crop, strong stress resistance, has preferable drought resisting, antifreeze
Etc. extreme weather, and yield is high, and quality of agricultural product is good, and it is high that peasant produces throwing ratio.
In in addition how there being the mode of trace element, have directly and fertiliser granulates blends and is added in fertiliser granulates
Portion, this two weeks modes are the most simple to operate, fertilizer production device, common list set compound fertilizer producing equipment production capacity (10
30) ten thousand tons, production of ammonium phosphate equipment mostly is single set production of ammonium phosphate equipment capacity 600,000 tons, and therefore equipment investment is high, any because of fertilizer
The scrap build that material upgrading needs all can be difficult to, and spends huge.Current portions fertilizer enterprise takes above two mostly
Mode produces the fertilizer containing middle trace element.But agricultural application process in find, aforesaid way produce containing middle trace
The fertilizer efficiency of the fertilizer of element is bad, and the compound fertilizer's fertilizer efficiency containing middle trace element namely taking above two mode to prepare is failed to understand
Aobvious, the fertilizer efficiency difference of trace element in interpolation is little with not having, the most remote with similar import fertilizer efficiency gap.
Mainly, middle trace element directly blends, because middle trace element is many analysis expert reason with conventional particles fertilizer
For salt, or powdery, it is impossible to combine uniformly with conventional particles fertilizer；Even if trace element in these is prepared as
Graininess, because of density, particle diameter difference, blends the fertilizer obtained and occurs isolation during transport uses, apply fertilizer in soil, meeting
Cause part Trace Elements in Soil excess, part soil lack again in micro-element nutrition.Middle trace element adds, with sulphuric acid
As a example by zinc, in fertilizer production preparation process, under the effect of moisture and temperature, can with the MAP in fertilizer system or
Diammonium phosphate (DAP) occurs to answer, and generates zinc phosphate indissoluble thing, causes zinc nutrient to be difficult to absorbed by crops.
Therefore the upgrading of Chinese tradition fertilizer, is not only the upgrading of nutrient data, is not required to the quick upgrading of scrap build,
With greater need for be effective upgrading of nutrient, ingenious upgrading.
To sum up, in China, being no matter the demand of crop centering trace element, in soil, nutrient is unbalance, or fertilizer is raw
The homogeneity of product enterprise is serious, and the performance of enterprises is poor, and the quickly upgrading being badly in need of conventional fertilizers realizes product differentiation, need not in a large number
Produce scrap build, and the premise of equipment investment exists, it is achieved fertilizer upgrading and transformation rapidly and efficiently.
Therefore, in this context, a kind of help common fertilizer (carbamide, phosphorus ammonium, potash fertilizer, compound fertilizer or organic fertilizer
Deng) quickly upgrade to the multi-functional emulsion form Additives Products containing middle microelement kind new-type fertilizer, become the task of top priority.
Summary of the invention
It is an object of the invention to provide a kind of common fertilizer of upgrading is the auxiliary agent containing secondary and micro-element fertilizers and preparation method, this
