Abstract
The present invention discloses a rare earth phosphoric fertilizer and its preparation method. It is made up by using common calcium as main fertilizer and adding a mixed solution containing rare earth, nitrogen, potassium and several trace elements and fertilizer regulating agent. By organically-combining phosphoric fertilizer production and rare earth production together, it can fully utilize several mineral effective components to produce high-effective rare earth phosphoric fertilizer which can improve growth environment of plant, activate soil, raise absorbing power of plants for absorbing several effective components, promote germination and tiller of seed, raise chlorophyll content and invigorate photosynthesis to attain the goal of increasing production of crops.
Description
The present invention relates to a kind of agrochemical, particularly utilize the rare-earth phosphate fertilizer that contains rare earth, nitrogen, potassium and trace element that rare earth, nitrogen, potassium and micro-mixing solutions are produced that contains of general calcium and two production line combination producing of rare earth.
Rare-earth phosphate fertilizer has varied, and its composition and production method are roughly the same." compound rare-earth-containing multicomponent fertilizer " announced from 91 years, 95 years patent gazettes of Patent Office of the People's Republic of China (CN1053051A) and " trace element compound fertilizer " patent application technology (CN1110266A), the latter is that a kind of physical mixed, each effective element are phosphorus, potassium, nitrogen evenly distribute basically basically, and the former be in various fertilizer, add the single rare earth element or multiple nitrate of rare earth element, muriate, be equipped with other trace element such as zinc, copper, molybdenum etc. according to the needs of plant.Their content is subjected to the restriction of the soil property, weather, current of experimenter or contriver's subjectivity influence and concrete Experimental Area etc. to a great extent.If a certain region long-term planting several plant, several important elements that this plant needs will be fewer and feweri in soil, so how to determine to lack which element or which and plant the element difficulty that will become.Best method is exactly to extract various effective nutrients from be soaked with the soil of planting such plant, makes the mixing solutions of certain salt, makes fertilizer with a kind of fertilizer after chemical reaction again.The effective ingredient of this fertilizer just can think that the partition of each element is from nature.Certain this soil must be suitable for planting plant especially through evidence.The plant of being planted must be all very good aspect quality, output.
Purpose of the present invention is exactly in order to overcome described the deficiencies in the prior art part, according to above-mentioned thinking, through research trial repeatedly for many years, seeking out with phosphate fertilizer is body material, with preparing rare-earth phosphate fertilizer with multiple element mixing solutions after chemical reactions such as nitrogenous, the potassium of rare earth combination producing, rare earth, copper, zinc, manganese, molybdenums.
The objective of the invention is to realize in such a manner: the preparation process of rare-earth phosphate fertilizer is at first to contain the sulfate liquor of N, K, REO and Cu, Zn, Mn, Sr etc. and regulate the solid amendment of proterties such as the fertilizer aqueous solution, diversity with preparation simultaneously in the process of producing rare earth, then with above-mentioned rock phosphate powder thorough mixing, react with dense (98%) sulfuric acid together, under 100 ℃ of-130 ℃ of condition of normal pressure, reacted 3-6 hour, produce except that containing secondary calcium phosphate, still contain the rare-earth phosphate fertilizer of multiple soluble phosphate, vitriol.
The insufficient content of trace element adds various mineral when producing rare earth to be controlled, these mineral and acid or alkali reaction, and generation solubility salt as Cu, Zn, Ni etc., can add copper glance and zink sulphide etc.
Generating the used mineral of rare earth can be solitary stone ore, bastnasite, Baotou rare earth ore deposit and ionic mineral.
The mixed solution H that contains rare earth, nitrogen, potassium and trace element that produces simultaneously with Rare Earth Production
+The ionic concn scope is: 10
-4.5-5N.
Can change according to mineral are different with the mixing solutions that rare-earth products is produced simultaneously, but all be chloride soln, nitrate solution, sulfate liquor, or the mixing solutions of any two or three kinds.
One ton of rare-earth phosphate fertilizer of every production, by weight percentage, (Rock Phosphate (72Min BPL) contains P more than or equal to 180 purpose rock phosphate powders in employing
2O
5Grade is 26-38%) 60-90%, contain the mixing solutions 10-20% of rare earth, nitrogen, potassium (REO:0.01-40g/L, N:0.1-30g/L, K:0.1-30g/L) and various trace elements (0.1-10g/L), fertilizer conditioner (REO:10-50%, P
