Abstract
The invention relates to a method for preparing high-efficiency phosphorus fertilizer without acidification. In the method, the material is ground by a vibration milling wet method to prepare super fine activated phosphate rock powder which has high specific surface area, the particle size is 90 percent and can passes through a 400-mesh sieve, the super fine activated phosphate rock powder is mixed with biological organic fertilizer according to the weight ratio of between 1 to 4 and 1 to 1, and pseudomonas fluorescens is added for mixing stockpile manure and fermenting so as to prepare the non-acidification high-efficiency phosphorus fertilizer. The method has the advantages of preparing the high-efficiency phosphorus fertilizer by physical and biological methods, reducing the environmental pollution, solving the problems of environmental pollution, high cost and the like existing in the prior phosphorus fertilizer preparation method and lowering cost of producing the phosphorus fertilizer, along with simple technique; moreover, in long-term usage, the phosphorus fertilizer can prevent the sealing of soil, improve the soil and enhance the soil fertility.
Description
One, technical field:
The present invention relates to the method that a kind of non-acidizing prepares efficient phosphorous fertilizer, belong to fertilizer processing and Application Areas.
Two, background technology:
At present, the used main raw material of known production phosphate fertilizer is a Rock Phosphate (72Min BPL), and decomposing phosphate rock stone mainly contains acid system and two kinds of methods of Re Fa.Acid system phosphate fertilizer, phosphate fertilizer or compound manure that general system makes with sulfuric acid, nitric acid, hydrochloric acid or phosphorolytic cleavage Rock Phosphate (72Min BPL), mostly acid system phosphate fertilizer is water soluble phosphorous fertilizer, as calcium superphosphate.Thermal process phosphatic fertilizer is at high temperature to add silica, rhombspar, coke etc. or do not add other batching decomposing phosphate rock stones and the phosphate fertilizer made, and mostly thermal process phosphatic fertilizer is citrate acid soluble phosphatic fertilizer, as fused(calcium magnesium)phosphate.But these methods all are by the preparation of chemical technology method, and the cost height, all have fluorine harm, acid harm, and toxic dust harm etc., and easily cause environmental pollution.The method that a kind of non-acidizing provided by the invention prepares efficient phosphorous fertilizer is in patent of invention " a kind of preparation method of the ultrafine activated phosphorusore compound fertilizer " (patent No.: ZL200610113874.3) the further improvement on the basis.Its major advantage is low-grade phosphorus ore in can utilizing, and production process only needs simple mechanical treatment and compost fermentation, and production cost is low and can not produce environmental pollution, and life-time service can be kept soil from packing together, and increases soil fertility, and improves the soil etc.
Three, summary of the invention:
In order to overcome existing environmental pollution among the conventional phosphate fertilizer preparation method, problems such as cost height the invention provides the method that a kind of non-acidizing prepares efficient phosphorous fertilizer, prepare phosphate fertilizer by physics, biological method, reduce environmental pollution, reduce the production cost of phosphate fertilizer.
The technical solution adopted in the present invention is:
1, (patent No.: ZL200610113874.3) to prepare granularity be 90% to cross the ultra tiny activating phosphorite powders of 400 purposes to disclosed method according to patent of invention " a kind of preparation method of ultrafine activated phosphorusore compound fertilizer ".
2, ultra tiny activating phosphorite powder and biological organic fertilizer (biological ight soil and domestic refuses such as cow dung, chicken manure, pig manure, industrial organic waste) are mixed by a certain percentage, its ratio is 1:4-1:1 by weight.
3, with ultra tiny activating phosphorite powder with after biological organic fertilizer mixes according to the above ratio, add Pseudomonas fluorescens (this bacterial classification is purchased the Institute of Micro-biology in Guangdong Province) again, adopt the secondary compost fermentation, for the first time ferment moisture controlled at 55%-65%, temperature is no less than 7 days greater than 55 ℃, and top temperature is no more than 75 ℃; For the second time ferment the initial stage moisture controlled 55%, the later stage is controlled at 25%-35%, and all turning is once weekly for fermenting twice.Twice compost fermentation periodic Control dried granulation at 30-60 days after fermentation is finished.
The invention has the beneficial effects as follows, the one, available phosphorus content height, the use of can topdressing; The 2nd, fertilizer efficiency is stable permanent, can make base manure and seed manure and use; The 3rd, soil there is improving effect, keep soil from packing together, increase soil fertility; The 4th, step of preparation process is few, and production process does not have the waste discharge, and is pollution-free; The 5th, the preparation method is simple, and cost is low; Low-grade phosphorus ore in can utilizing is saved mineral wealth.
