Embodiment 1

[0032] The raw materials citric acid, tea saponin, saponin, humic acid, fulvic acid, amino acid and chitin are weighed according to mass percentage, and the mass ratio is citric acid: tea saponin: saponin: humic acid: yellow Humic acid: amino acid: chitin = 5: 38: 5: 25: 10: 10: 4, after mixing all the substances evenly, according to the raw material: water = 1: 0.3, dissolve in water to make a solution, and then get the said foliar inhibitors.

[0033]Test location: a rice planting area in Changsha County, Hunan Province

[0034] (1) Using the cadmium detection method stipulated in the "National Food Safety Standard for the Determination of Cadmium in Food" (GB5009.15-2014), the content of cadmium in rice without spraying foliar inhibitors in this area was determined to be 0.32mg / kg, the cadmium content in the soil samples was determined by the heavy metal detection method stipulated in the "Soil Environmental Quality Standard" (GB15618-2008), and the maximum detection cont...

Abstract

The invention discloses a foliage resistance and control agent for lowering cadmium pollution to crops and a using method. The foliage resistance and control agent is prepared from tea saponin, saponin, citric acid, humic acid, amino acid, fulvic acid and the like. As the resistance and control agent is sprayed to foliages, after effective ingredients of the resistance and control agent are absorbed by the foliages, heavy metal cadmium can be effectively prevented from being conveyed to edible portions of the crops, and the cadmium content in agricultural products is reduced.

Description

technical field [0001] The invention relates to the field of agricultural product quality and safety, in particular to a foliar resistance control agent for reducing heavy metal cadmium pollution of agricultural crops and a use method thereof. Background technique [0002] Since the discovery of cadmium in the early 20th century, the output of cadmium has increased year by year. The main sources of pollution are lead-zinc mines, non-ferrous metal smelting, electroplating, and factories using cadmium compounds as raw materials or catalysts. A considerable amount of cadmium is discharged into the environment through waste gas, waste water, and waste residues, causing pollution. At present, cadmium pollution is widespread all over the world. Cadmium entering the human body, in addition to causing osteoporosis, bone atrophy, and joint pain, is mainly accumulated in the liver, kidney, pancreas, thyroid, and bones. It can cause pathological changes in kidney organs, etc., and af...
