Preparation for reducing enrichment of nitrate and heavy metal of oilseed rape

Abstract

The invention provides a preparation for reducing enrichment of nitrate and a heavy metal of oilseed rape; the preparation comprises 3.5-4.0 g / L of potassium sodium tartrate, 1.4-1.8 mmol / L of tetraethoxysilane, 0.1-0.2 g / L of alanine, 0.1-0.2 g / L of threonine, 7-8 mg / L of NAA, 0.2-0.5 mmol / L of FeSO4 and 0.05-0.1 g / L of guanylthiourea. The contents of the nitrate and the heavy metal in the oilseed rape can be decreased significantly, the content of the nitrate can be as low as 260.55 mg / kg and is significantly lower than a control group of 827.23 mg / kg; the content of Cd in the oilseed rape can be as low as 0.013 mg / kg and is far lower than the control group of 0.121 mg / kg.

Description

technical field [0001] The invention relates to a preparation for reducing the accumulation of nitrate and heavy metals in vegetables, in particular to a preparation for reducing the accumulation of nitrate and heavy metals in rapeseed. Background technique [0002] Vegetables are one of the indispensable foods for people. They provide humans with a variety of mineral nutrients, amino acids, vitamins and cellulose, and play an important role in maintaining human health. At the same time, vegetables are relatively easy to accumulate nitrate and heavy metals. [0003] After nitrate enters the human body, it is absorbed by the small intestine, and the bacteria in the intestine will reduce the nitrate to subsalt. On the one hand, nitrite can convert the iron in the hemoglobin into high-valent iron, so that the hemoglobin loses the ability to carry oxygen Transport capacity, causing methemoglobinemia. Severe cases will show symptoms such as dyspnea, blood pressure drop, coma, c...
