Description
Technical field
The invention belongs to organic-inorganic compound fertilizer preparing technical field, be related to it is a kind of prepared using natural phosphorus ore containing it is non-
Dissolubility phosphate fertilizer, the process compound with nitrogen potassium after mixed fermentation, it is organic to prepare slow release in particular with natural phosphorus ore containing
Inorganic complex fertilizer production new technique method.
Background technology
Chemical Mixed Fertilizer is by the npk nutrient fertilizer mixed compound by a certain percentage.Relative to single-element fertilizer,
Chemical Mixed Fertilizer nutrition is comprehensive, and administration is time saving and energy saving.Organic-inorganic compound fertilizer is a kind of not only answering containing organic matter but also containing appropriate chemical fertilizer
Complex fertilizer.It is to organic materials such as excrement, turfs, carries out innoxious and validation by microbial fermentation and handles, and adds suitable
Quantify fertilizer, humic acid, amino acid or beneficial microbe bacterium, through granulation or directly blending prepared by commercial fertilizer.
Phosphorus, it is that the mankind depend on for existence and irreplaceable resource, and the phosphate fertilizer as agricultural production base substance consumes
80% phosphate rock resource.While grain-production miracle is created using quick-acting chemical fertilizer energetically, water pollution, soil plate are also triggered
The a series of environmental problems such as knot, ardealite stacking.Particularly Phosphate Fertilizer Industry is still prepared based on water-soluble chemical phosphate fertilizer with acid system,
Since 2006, China uses 11,000,000 tons of chemical phosphatic ferfilizer every year（According to pure P2O5Metering）.Production and application acid system water soluble phosphorous fertilizer
And the environment triggered has with resource problem：
Water soluble phosphorous fertilizer is lost in and pollution of waterhead.Phosphate radical is easily with irrigation or natural rainwater after water soluble phosphorous fertilizer is applied to field
It is lost in or reacts to form new insoluble phosphorus ore containing with other mineral constituents in soil, the effective phosphorus utilization deficiency of crop
20%.A large amount of P elements enter ground fresh water with surface water, form the rich phosphatization pollution of area source of algae procreation basic substance.Change
Learn phophatic fertilizer production process and produce new pollution sources.Acid system produces calcium superphosphate and the acid consumption of phosphorus ammonium is huge.China's life in 2008
Produce phosphorus ammonium（MAP+DAP）Class fertilizer amounts to 7,400,000 tons of P2O5, nearly 28,000,000 t of high-quality phosphorus ore, consumption sulfuric acid 21,000,000 t are consumed altogether.One
It is that the most of sulphur for preparing sulfuric acid needs import, second, being converted to the phosphorus that tens million of tons are difficult to work with again during production of ammonium phosphate
Gypsum, produce new pollution sources.
It is contemplated that fertilizer utilization is improved as phosphorus source by using the ground phosphate rock that controlled micro crystallization and organic fermentation activate
Rate, reduce phosphorus chemistry fertilizer production and using pollution caused by process, stabilize soil acidification caused by fertilising.
