Problems solved by technology

Engineering measures are relatively classic heavy metal pollution control measures for cultivated land. They have the advantages of thoroughness and stability. However, the implementation of engineering measures requires a large amount of engineering and high investment costs, which will damage the soil structure and cause a decrease in the fertility of the cultivated land. stack or process
[0007] The existing publication number is CN107897207A, which is a foliar inhibitor and control agent for reducing heavy metal cadmium pollution in rice. The raw materials of the foliage inhibitor and control agent designed by the invention include soluble silicon, soluble zinc, surfactant, potassium humate and Water, through foliar spraying, can effectively inhibit the transportation of heavy metal cadmium to rice and reduce the cadmium content in rice. This will not only block heavy metals, but also prevent crops from absorbing beneficial metal ions from outside, so that the nutrient intake of crops will not keep up
[0008] There is also a method for reducing the absorption of heavy metals on the foliage of crops with the publication number CN105794557A. The raw materials of the foliage resistance control agent disclosed in this invention are sodium chloride, calcium chloride, and water. However, not only the leaves of crops can absorb, but also the roots can absorb, so the effect is not good

Abstract

The invention provides a leaf surface blocking and controlling agent for inhibiting heavy metal pollution of crops, a preparation method thereof and a treatment method of a heavy metal polluted rice field, and relates to the technical field of heavy metal polluted cultivated land treatment. The designed leaf surface blocking and controlling agent can effectively block pollution of heavy metal to crops, can accelerate absorption of external nutrition by the crops, promotes photosynthesis of plants, and improves the quality of the crops.

Description

[0001] This application is a divisional application with an application date of March 3, 2021, an application number of 202110234006.5, and the title of the invention "Formulation and preparation method of a foliar inhibitor for inhibiting heavy metal pollution in crops". technical field [0002] The invention relates to the technical field of treatment of heavy metal-contaminated cultivated land, in particular to a foliar inhibitor and control agent for inhibiting heavy metal pollution of crops, a preparation method thereof, and a treatment method for heavy metal-contaminated paddy fields. Background technique [0003] Heavy metal elements can change the activity of soil microorganisms and affect the enzyme activities in the soil, thereby affecting the release and bioavailability of nutrient elements in the soil. In addition, heavy metal elements can also inhibit the respiration of plant roots, thus affecting the absorption of nutrients by crops. Heavy metal pollutants also...
