Problems solved by technology

Among them, although the phytoremediation method is economical and environmentally friendly, its treatment cycle is long, and the paddy fields will temporarily lose production capacity. Applying lime to the soil to adjust the soil pH or redox (EH) to reduce the bioavailability of cadmium in the soil, so as to control the accumulation of cadmium in rice. Although the effect is quick and the effect is obvious, the amount of lime and other chemicals is relatively small. Large, relatively high cost, and may have a negative impact on the soil environment of paddy fields, which has become a bottleneck restricting its development

Abstract

The invention provides a foliar fertilizer for preventing and controlling heavy metals in rice as well as a preparation method and a use method of the foliar fertilizer. The foliar fertilizer is composed of a main control component, a synergistic component, a surfactant, a penetrating agent, an adsorbent and nutritional components. Through reasonable matching of the raw materials, the effect of better reducing the content of heavy metals is achieved on the premise of ensuring the absorption rate of leaf surfaces.

Description

technical field [0001] The invention relates to a foliar fertilizer, in particular to a foliar fertilizer for the prevention and control of heavy metals in rice, a preparation method and a use method, and belongs to the technical field of foliar fertilizer and heavy metal control. Background technique [0002] Heavy metals are widely distributed in the atmosphere, water, soil, and organisms. Rice is the largest grain crop in my country, and it is also the bulk cereal crop with the strongest accumulation of heavy metal cadmium. The area of ​​farmland polluted by heavy metals such as cadmium in my country is increasing year by year. From 2002 to 2003, the Ministry of Agriculture of my country conducted a general survey on the quality and safety of rice produced all over the country, showing that cadmium content in 10% of rice exceeded the standard, and the cadmium content in rice in some cadmium-polluted areas was as high as 0.4-1.0 mg / Kg. Cadmium pollution in rice is threate...
