A kind of foliar inhibitor for suppressing cadmium pollution of wheat atmospheric dust and its application method

Abstract

The invention discloses a foliar resistance control agent for suppressing cadmium pollution from atmospheric dust in wheat and a method for using the same, belonging to the technical field of environmental pollution control. 3 o 4 @C‑NH 2 0.2%, alkyl naphthalene sulfonate 1‑2%, lambda-cyhalothrin 0.5‑1%, water 91.8‑95.3%; spray the foliar inhibitor on wheat leaves during the filling stage of wheat, which can reduce The bioavailability of cadmium in the atmospheric dust adsorbed on the leaf surface directly cuts off the absorption of heavy metal cadmium in the atmospheric dust by the leaves, and then efficiently and significantly prevents the absorption of cadmium in the atmospheric dust and its transfer to the grain, reducing the cadmium content in the grain. It provides a new solution to control the cadmium pollution of wheat grains caused by cadmium in atmospheric dust.

Description

technical field [0001] The invention belongs to the technical field of environmental pollution control, and in particular relates to a foliar inhibitor and control agent for suppressing cadmium pollution from atmospheric dustfall in wheat and a use method thereof. Background technique [0002] The heavy metal cadmium (Cd) is one of the most harmful metal elements. As one of the three major food crops in the world, the problem of wheat being polluted by Cd has become more and more serious. More and more studies have found that atmospheric Cd deposition has become an important source of Cd accumulation in farmland, especially around smelters and mines. Studies have shown that wheat can not only absorb Cd in soil through roots, but also directly absorb Cd in atmospheric dust through leaves and other shoots. At the same time, the leaves of cereal crops can directly absorb Cd from the atmosphere and transfer it from the leaves to the kernels, and the contribution rate of Cd to m...

Problems solved by technology

It can be seen that the current patented technologies and products do not take into account the impact of the two pollution sources of atmospheric dust and soil on wheat grains, especially the fact that the Cd in wheat grains mainly comes from atmospheric dust, and there is still a lack of targeted control methods and methods. Inhibition and control agent products cause the Cd content of wheat grains to often exceed the standard, and the control effect of Cd pollution in grains is unstable, low in efficiency and high in cost, which has become the bottleneck of scientific prevention and control of Cd pollution in wheat grains

[0005] Therefore, the control technology of atmospheric dust on wheat leaves and grains Cd pollution is still blank, and it is necessary to develop foliar inhibitors that directly block wheat leaves from absorbing Cd in atmospheric dust, so as to reduce the Cd content of grains
