Problems solved by technology
Due to the "nearest transport" principle of photosynthetic products, compared with the leaves under the ear, photosynthetic products in the ear have the shortest distance to the grain, and the transport efficiency is the highest; at the same time, these characteristics also determine that the Pb absorbed by different parts of the ear may be easier to accompany Translocation of ear-filling material rapidly migrates into the kernel, thereby affecting Pb content in post-harvest wheat kernels
[0004] However, the existing technologies and prevention and control products all pay attention to the pre

Example Embodiment
[0025] The following Fe 3 O 4 The preparation method of @ c-cooh is specifically refer to the patented "a magnetic carboxylated hollow microsphere soil repair agent, the preparation method thereof and the application"
[0026] (ZD201810251832.9).
Example Embodiment
[0027] Example 1
[0028] This embodiment provides a spike-resistant control agent for wheat grain lead lead, which is made of the following mass percent raw materials:
[0029] Manganese sulfate 0.2%, 0.4% magnesium sulfate, 0.2% sulfate, 3% humic acid, Fe 3 O 4 @ C-COOH 0.2%, alkyl naphthalenesulfonate, 0.2% of chloride cyptide esters of 10%, and the amount of water;
[0030] The preparation method of the ear-proof control agent includes the following steps:
[0031] S1: According to the mass percentage, manganese sulfate is 0.2%, 0.4% magnesium sulfate, 0.2% zinc sulfate, 3% humic acid, Fe 3 O 4 @ C-COOH 0.2%, alkyl naphthalenesulfonate, 0.2% of chloride cyptide esters of 10%, and the amount of water;
[0032] S2: Sequentially adding the raw material weighing in S1 and dispersed in the water, and the time of ultrasonic dispersion after each raw material is 30 min, and the water temperature of the ultrasonic dispersion of sulfate is 30 ° C; after the dispersion is completed, the...

Abstract
The invention belongs to the technical field of environmental pollution treatment, and particularly relates to an ear retarder for reducing lead in wheat grains and a preparation and application method thereof. The ear retarder is prepared from the following raw materials in percentage by mass: 0.2 to 0.4 percent of manganese sulfate, 0.2 to 0.4 percent of magnesium sulfate, 0.2 to 0.4 percent of zinc sulfate, 3 percent of humic acid, 0.2 percent of Fe3O4@C-COOH, 1 percent of alkyl naphthalene sulfonate, 0.2 percent of cyhalothrin and the balance of water. The preparation method comprises the following steps: S1, respectively weighing the following raw materials in percentage by mass: 0.2 to 0.4 percent of manganese sulfate, 0.2 to 0.4 percent of magnesium sulfate, 0.2 to 0.4 percent of zinc sulfate, 3 percent of humic acid, 0.2 percent of Fe3O4-coated C-COOH, 1 percent of alkyl naphthalene sulfonate, 0.2 percent of cyhalothrin and the balance of water; and S2, uniformly mixing the raw materials in the S1 to obtain the ear retarder. The ear retarder provided by the invention can achieve the effect of reducing the content of Pb in wheat grains by inhibiting the absorption of Pb in atmospheric dust fall by wheat ears; and according to the ear retarder provided by the invention, all the components are harmless to a human body, the application mode is simple, and the beneficial effects are obvious.
Description
technical field [0001] The invention belongs to the technical field of environmental pollution control, and in particular relates to an ear inhibitor and control agent for reducing lead in wheat grains and a preparation and application method thereof. Background technique [0002] Wheat is the third largest food crop in the world after rice and corn, and is the main dietary component of Chinese residents, and is also considered to be one of the main sources of human Pb intake. The agricultural environment in our country is frequently polluted by heavy metals, among which the pollution of Pb in soil is more common. Current research on Pb pollution in soil and crops, such as remediation of Pb-contaminated soil, screening of wheat varieties with low Pb accumulation, etc., mainly focuses on the environmental behavior of Pb in the soil-plant system. However, according to literature reports, heavy metal Pb in wheat grains generally enters into wheat through two ways. The first o...
