Abstract
The invention relates to the field of agricultural production materials, in particular to fertilizer. The fertilizer comprises original fertilizer and sodium poly-aspartate, wherein the original fertilizer comprises the following components in percentage by mass: 12 to 15 percent of nitrogen, 6 to 25 percent of phosphorus pentoxide and 6 to 25 percent of potassium oxide; the mass ratio of the sodium poly-aspartate to the original fertilizer is (0.6-0.8):1. The fertilizer provided by the invention contains abundant elements such as nitrogen, phosphorus and potassium so as to effectively guarantee the nutrients required by the growth process of crops; more importantly, polyaspartic acid is a polymerization amino acid with a carboxylic acid side chain and is a polymer formed by condensing an amino group and acarboxyl group of an aspartic acid monomer. The sodium poly-aspartate is the metal salt of the polyaspartic acid and can chelate a plurality of metal ions, so lead ions absorbed by the crops are effectively reduced and lead deposited 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, reduce the fertilizer of crop to Plumbum absorption in particular to a kind of.
Background technology
Harmful heavy metal pollutes and refers to the ecological environmental pollution caused by harmful heavy metal or its compound.Lead contamination, as one of principal pollutant that harmful heavy metal pollutes, the health of human body in serious threat.It enters in body as the toxic heavy metal can put aside in human body and animal tissues by skin, digestive tube, respiratory tract, affine with multiple organ, accumulate, and causes anemia, nervous function to lack of proper care 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 crop that people are often edible leaded, causes in the histoorgan of a large amount of lead deposits in human body, to the huge threat that the health of human body causes.
Summary of the invention
The object of the present invention is to provide a kind of fertilizer, to solve the above problems.
Provide fertilizer in an embodiment of the present invention, comprise original fertilizer and sodium polyaspartate, by mass percentage, in original fertilizer, the content of 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 sodium polyaspartate is 0.6 ~ 0.8:1 with the ratio of original fertilizer total mass.
The fertilizer of the above embodiment of the present invention, not only contains the abundant element such as nitrogen, phosphorus, potassium in fertilizer, effectively ensure that nutrient required in process of crop growth; And what is more important, poly aspartic acid is a kind of polymeric amino acid with carboxylic acid side chain, is the amino of aspartic acid monomer and the polymkeric substance of carboxyl shrink.Sodium polyaspartate is its metallic salt, can chelating many kinds of metal ions, effectively reduces the absorption of crop to lead ion, decreases the deposition of plumbous histoorgan in human body.
