Abstract
The invention discloses a formula for producing a special blending fertilizer for paddy rice by combining a calcium magnesium phosphate powder with a fertilizer source of urea. The invention is characterized in that: the calcium magnesium phosphate powder is combined with fertilizer sources of granular superphosphate and urea to form a layer of calcium magnesium phosphate film on the granular surface; the special blending fertilizer not only prevents the deliquescing phenomenon caused by direct contact of superphosphate with urea, but also can reduce phosphorus fixation and utilization of slow release nitrogen when applied into soil; furthermore, the calcium magnesium phosphate fertilizer contains medium trace elements essential to crop growth, and is truly a multi-element compound fertilizer. 0.9-1.1 parts of high quality calcium magnesium phosphate powder, 4.1-4.3 parts of combination urea, 0.4-0.6 part of monoammonium phosphate, 1.2-1.4 parts of granular superphosphate and 2.9-3.1 parts of potassium chloride are subjected to dry mixing and blending and packaging by bags; and the blending fertilizer contains 44% of total nutrients of nitrogen, phosphorus and potassium, wherein the three are in the ratio of 20:6:18.
Description
design field
The present invention relates to fertilization compositions based on earth measurement chemical fertilizer field, be specifically related to produce mixing fertilizer specially for paddy rice formula with sources of manure such as the general calcium of calcium magnesium phosphorus powder compatibility particle.
Background technology
At present, promote in the world Bulk Blending Fertilizer and contain very much emergingly, be characterized in that fertilizer efficiency is high, price is low, with strong points, in the every 50 kilometers of radius region of Japan, just have a fertilizer mixing station, just more than 800 formulas nearly of each fertilizer mixing station; And though China promotes Formula fertilization by soil testing for a long time, practical situation " push away and do not open "; Its reason peasant does not know chemical fertilizer characteristic, does not more know crop regulation of fertilizer requirement, is difficult to produce preparation bulk blended fertilizer.The good news is, by 2008, there was Bulk Blending Fertilizer standard (GB1633-2008) in country, and " changing rational application of fertilizers for executing formula fertilizer " also advocated by agricultural technology spread department of China, makes this technology obtain tremendous development; But in actual production process, often there is the product deliquescence imagination, have several stations even to occur that up to a hundred tons of product deliquescence become empty bag; Its reason is that general calcium has risen and reacted with urea, in the face of this difficult problem, we have worked out by source of manure production Bulk Blending Fertilizer such as the calcium magnesium phosphorus powder general calcium of compatibility particle and urea, one can deliquescence, two can not lump, obtain good physical behavior, its principle is, fused(calcium magnesium)phosphate is pulvis, and the sources of manure such as the general calcium of fusion particle and urea, make its particle surface form one deck calcium magnesium phosphorus film, not only prevent the direct deliquescence phenomenon occurring that contacts of general calcium and urea, and, after being manured into soil, also can reduce the utilization of phosphorus fixation and slow-release nitrogen, thereby do the agronomy efficiency of nitrogen high; Moreover fused(calcium magnesium)phosphate not only contains 12%～20% P

Summary of the invention
The present invention, for fertilization of rice, reaches the object of increasing income and economizing on spending.The present invention adopts following technical scheme, and the soil characteristic science that is mostly " rich potassium meta-alkali, the few nitrogen of scarce phosphorus " according to the regulation of fertilizer requirement of paddy rice and northern China is formulated; With 0.9～1.1 part of its high-quality calcium magnesium phosphorus powder, 4.1～4.3 parts, compatibility urea, 0.4～0.6 part of monoammonium phosphate, 1.2～1.4 parts of the general calcium of particle, 2.9～3.1 parts, Repone K, be dry mixed stirring fusion, bag distribution packaging, puts on market, for the production of, this Bulk Blending Fertilizer nitrogen phosphorus potassium total nutrient is 44%, and nitrogen, phosphorus, potassium are than being 20:6:18; Because this Bulk Blending Fertilizer has very strong specific aim, so every mu is executed one bag of this Bulk Blending Fertilizer, comparable to execute 3～5 bags of urea productions high.
Specific embodiments
With 100 kilograms of its high-quality calcium magnesium phosphorus powders, 420 kilograms, compatibility urea, 50 kilograms of monoammonium phosphates, 130 kilograms of the general calcium of particle, 300 kilograms, Repone K, is dry mixed stirring fusion, and bag distribution packaging, puts on market, for the production of, this Bulk Blending Fertilizer nitrogen phosphorus potassium total nutrient is 44%, nitrogen, phosphorus, potassium are than being 20:8:18; Concrete blending parameter is seen following table:
