Abstract
The invention relates to the field of agricultural production materials, and in particular relates to a fertilizer for reducing lead absorption of crops. The fertilizer comprises an original fertilizer and potassium fulvic acid, wherein the original fertilizer comprises the following components in percentage by mass: 12-15 percent of nitrogen, 6-25 percent of phosphorus pentoxide and 6-25 percent of potassium oxide; the ratio of the mass of the potassium fulvic acid to the total mass of the original fertilizer is 0.05-0.09:1. According to the fertilizer provided by the embodiment of the invention, the absorption of the crops to lead ions is effectively reduced, and the deposition of the lead in tissues and organs of a human body is reduced.
Description
Technical field
The present invention relates to capital goods in the agricultural sector field, in particular to a kind of fertilizer of crop to Plumbum absorption that reduces.
Background technology
Harmful heavy metal pollutes and refers to the ecological environmental pollution being caused by harmful heavy metal or its compound.Lead contamination, one of principal pollutant that pollute as harmful heavy metal, the health of human body in serious threat.It,, as the toxic heavy metal that can put aside in human body and animal tissues, enters in body by skin, digestive tube, respiratory tract, and, accumulation affine with multiple organ causes anemia, nervous function imbalance and injury of the kidney.In correlation technique, all contain lead in the raw materials for production of nearly all fertilizer, when applying such fertilizer on crop, in crop, lead content obviously increases.The often edible leaded crop of people, causes in the histoorgan of a large amount of lead deposits in human body, and the health of human body is caused to huge threat.
Summary of the invention
The object of the present invention is to provide a kind of fertilizer, to solve the above problems.
Fertilizer is provided in an embodiment of the present invention, has comprised original fertilizer and potassium fulvate, according to the mass fraction, the content of original Nitrogen is 12%～15%, and the content of Vanadium Pentoxide in FLAKES is 6%～25%, and the content of potassium oxide is 6%～25%; The quality of potassium fulvate is 0.05～0.09:1 with the ratio of original fertilizer total mass.
The fertilizer of the above embodiment of the present invention not only contains the elements such as abundant nitrogen, phosphorus, potassium in fertilizer, has effectively guaranteed needed nutrient in process of crop growth; And, what is more important, potassium fulvate is the polycondensate of a kind of multivalence phenol type aromatics and nitrogen compound, its can with lead ion organic complex, absorption, reduce the activity of lead ion, effectively reduce the absorption of crop to lead ion, reduced the deposition of plumbous histoorgan in human body.
