Abstract

The invention relates to the field of heavy metal pollution control, and discloses application of a silicon-containing regulator in crop seed soaking, a seed soaking composition and a seed soaking method. The invention provides an application of a silicon-containing regulator in crops, and the silicon-containing regulator is selected from at least one of silicate, aminated silatrane and nano silicon. The seed soaking composition provided by the invention comprises the silicon-containing regulator and the solvent, and when the seed soaking composition is used for soaking crop seeds, the enrichment of heavy metals by crops can be reduced, the germination rate of the seeds is improved, and the growth of the crops is promoted.

Description

technical field [0001] The invention relates to the field of heavy metal pollution prevention and control, in particular to the application of a silicon-containing conditioner in seed soaking of crops, a seed soaking composition and a seed soaking method. Background technique [0002] Cadmium (Cd) is a metal element that exists widely in nature. Excessive intake of Cd or long-term exposure to trace amounts of Cd can seriously harm human health. In recent years, soil Cd pollution caused by mining and smelting has become increasingly serious. After heavy metal Cd enters the soil, due to its high biological activity, it is easily absorbed and enriched by plants, and it brings harm to human health through the food chain. With the increasing seriousness of Cd pollution in farmland soil, how to alleviate and inhibit the toxicity of Cd to plants has attracted extensive attention. Silicon (Si) is an indispensable element in the production and development of crops. In the agricultu...
