Abstract
The present invention discloses long-effective citrate-soluble phosphate fertilizer. Natural apatite is used as principal raw materials and is pulverized physically and mixed. The present invention has the proportioned by weight of components: 56 to 70% of coincidence phosphate, 30 to 40% of chlorite and 0 to 4% of blood meal. The present invention has the advantages of long fertilizer effect, safety and no public hazard, and can be widely applied to the planting field of crops and technical crops.
Description
Technical field
The present invention relates to a kind of phosphate fertilizer, relating in particular to a kind of is the nuisanceless long-acting phosphate fertilizer of raw material with natural phosphatic rock.The phosphate fertilizer technical field that belongs to Division of Chemistry.
Background technology
Water-soluble chemical fertilizer (ammonium phosphate, superphosphate) produces public hazards owing to can permeate soil to soil, and simultaneously, the amount that the crop absorption of being applied fertilizer is fallen to utilize only accounts for about 15% of total amount, serious waste of resources.According to the research report result, residual fertilizer flows into soil, has destroyed the trace mineral to plant-growth necessity, such as, iron, key elements such as manganese, boron, lead, copper, molybdenum, magnesium and silicon element are drilled so that insoluble state is heavy.Though this process can not take place rapidly, suppressed the activity of microorganism, the inflow stream polluted water that fails to be convened for lack of a quorum.For this reason, countries in the world are badly in need of changing present this present situation, and hope can have a kind of fertilizer efficiency long, and can drop into application to soil and the free of contamination phosphate fertilizer of farm crop.
Studies show that calcium phosphate powder does not have water miscible characteristic, solubility in citric acid (the molten rate 90% of Chinese holly), when giving soil application with powder, farm crop sponge a part according to the needs of oneself, remaining residual phosphate can be dissolved by acidic fertilizier as organic acid.Can absorb the micro-composition (iron in the soil solution, manganese, magnesium, copper) plasma, because it has the phenomenon that recrystallize can appear in processable (solubility in citric acid), thereby can be dissolved absorption once more by plant, therefore, can not be penetrated in the soil and go, thereby be a kind of nuisanceless, the safe fertilizer of high-level efficiency, close environment.
Summary of the invention
The technical issues that need to address of the present invention, purpose promptly of the present invention is in order to provide a kind of fertilizer efficiency long, to soil and the free of contamination safety nuisance free phosphate fertilizer of farm crop.
Technical problem of the present invention can solve by taking following measure:
Long-effective holly soluble phosphate fertilizer is a main raw material with natural phosphatic rock, and through physical pulverization, be mixed and processed its weight percentages of components: overlapping phosphorus is 56～70%, and chlorite is 30～40%, and blood meal is 0～4%; Wherein overlap main ingredient weight percent in the composition of phosphorus: nitrogen is 3.5～7.0%, and Vanadium Pentoxide in FLAKES is 5～10%,
*Potassium is 2～5%, and calcium oxide is 25～40%, and magnesium oxide is 3～7%.
Technical problem of the present invention also can solve by taking following measure:
Further available following weight percentages of components: overlapping phosphorus is 60%, and chlorite is 39.5%, and blood meal is 0.5%.
Its best composition weight percent: overlapping phosphorus is 60%, and chlorite is 39.5%, and blood meal is 0.5%.
Overlapping phosphorus, also to contain weight percent be 0.03～0.07% water-soluble copper and water-soluble manganese mixture.
Overlap best each weight percentages of components of phosphorus: nitrogen is 5.5%, and Vanadium Pentoxide in FLAKES is 7.2%, and potassium is 4%, and calcium oxide is 33%, and magnesium oxide is 5%, and the water-soluble copper (Cu) and the water-soluble manganese (Mn) of trace are 0.05%.
Compared with prior art, the present invention has following beneficial effect:
Phosphate fertilizer among the present invention exists with the comprehensive salt form of solubility in citric acid, and is water insoluble, can not penetrate into deep subsoil, also can not make soil generation chemical transformation; Evidence p fertilizer efficiency of the present invention is long, single-dose application, and fertilizer efficiency can be kept the several years, and according to farm crop and weather condition, can select the different modes fertilising for use.
Embodiment
Below in conjunction with specific embodiment the present invention is specifically described.
Embodiment 1:
With natural Rock Phosphate (72Min BPL) is main raw material, prepares long-effective holly soluble phosphate fertilizer according to following component, and overlapping phosphorus is 56%, and chlorite is 40%, and blood meal is 4%, through physical pulverization, be mixed and processed.Wherein overlap best each weight percentages of components of phosphorus: nitrogen is 5.5%, and Vanadium Pentoxide in FLAKES is 7.2%, and potassium is 4%, and calcium oxide is 33%, and magnesium oxide is 5%, and the water-soluble copper (Cu) and the water-soluble manganese (Mn) of trace are 0.03%, and all the other are invalid components.
