Problems solved by technology
[0003] At present, the promotion of blended fertilizers is very prosperous in the world. It is characterized by high fertilizer efficiency, low price, and strong pertinence. In Japan, there is one fertilizer distribution station within a radius of 50 kilometers, and each fertilizer distribution station has as many as eight There are more than one hundred formulas; and although the technology of soil testing and formula fertilization has been popularized in my country for a long time, the actual situation is "push and cannot be opened"; the reason is that farmers do not know the characteristics of chemical fertilizers, let alone the law of fertilizer needs of crops, so it is difficult to produce and prepare blended fertilizers

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
[0001] design field [0002] The invention relates to the field of soil testing formula fertilization and chemical fertilizers, in particular to a special blend fertilizer formula for rice produced by using calcium magnesium phosphorus powder compatible with granular common calcium and other fertilizer sources. Background technique [0003] At present, the promotion of blended fertilizers is very prosperous in the world. It is characterized by high fertilizer efficiency, low price, and strong pertinence. In Japan, there is one fertilizer distribution station within a radius of 50 kilometers, and each fertilizer distribution station has as many as eight There are more than one hundred formulas; and although the technology of soil testing and formula fertilization has been popularized in my country for a long time, the actual situation is "push and cannot be opened"; the reason is that farmers do not know the characteristics of chemical fertilizers, let alone the law of fertilizer...
