Abstract

The invention relates to an amino-acid-containing selenium-rich cadmium reduction leaf fertilizer and a use method. According to the fertilizer, amino acid, zinc gluconate and sodium selenite are organically chelated to prepare zinc selenium amino acid, lecithin and vitamin E serve as a carriers, the amino-acid-containing selenium-rich cadmium reduction leaf fertilizer is high in activity, safe and efficient and prepared, affinity of the amino-acid-containing selenium-rich cadmium reduction leaf fertilizer and plants is achieved, selenium and zinc elements are effectively absorbed by the plants, movement and transport of the selenium and zinc are facilitated, absorption conversion efficiency of the selenium is increased, the contents of the selenium and the zinc in rice is increased, entering and migration of heavy metal such as cadmium and arsenic are blocked, and absorption for heavy metal such as cadmium and arsenic is restrained by adjusting stem and leaf distribution, transportation of protein activity and competition of transport corridors. The method is implemented at the normal temperature and at the normal pressure, the method is simple in process and convenient to operate, mass production is easily achieved, used raw materials are wide in source, and the fertilizer is low in cost and less in pollution.

Description

technical field [0001] The invention belongs to the field of foliar fertilizers, in particular to an amino acid-containing, selenium-enriched and cadmium-reduced foliar fertilizer and its application method. Background technique [0002] At present, my country's soil heavy metal pollution is becoming more and more serious. In 2014, the Ministry of Environmental Protection and Land Resources' "National Survey Bulletin on Polluted Soil" pointed out that the quality of my country's cultivated land soil environment is worrying, and the total point exceeding the standard rate of the country's soil is 16.1%, while the number of points exceeding the standard for inorganic pollutants accounts for all the points exceeding the standard. 82.8% of the total, of which 7.0% exceeded the standard rate of cadmium points. In 2016, the "Soil Pollution Prevention and Control Action Plan" issued by the State Council pointed out that the current overall situation of my country's soil environment...
