Abstract

The invention discloses a foliage resistance and control agent for lowering lead 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 lead can be effectively prevented from being conveyed to edible portions of the crops, and the lead 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 lead pollution of agricultural crops and a use method thereof. Background technique [0002] Lead in soil has both natural and anthropogenic sources. Lead has low solubility in soil, is not easy to migrate, and has a long residence time. It is a non-degradable environmental pollutant, and its hazards are latent and long-term. Lead-containing soil not only affects soil microorganisms, enzyme activity, and physical and chemical properties, but also pollutes surface water twice and endangers human health through the food chain. Studies have shown that there is a direct relationship between the blood lead level of the human body and the lead content in the soil. The damage of lead to human body functions is multi-organ and diverse. It is a central nervous system poison, and the harm to children's intell...
