摘要：
The present invention relates to the field of environmental protection, and in particular to a leaf surface barrier for ac- curately controlling cadmium absorption and transport related gene expression in rice, and an application thereof. The present inven- tion comprises: reducing a raw material, i.e., selenious acid or selenite, by using ascorbic acid to generate a nanogel, and then emul- sifying the managed for peptization to obtain a leaf surface barrier for accurately controlling cadmium absorption and transport re- lated gene expression in rice; and then mixing the leaf surface barrier with a silica sol to obtain a composite selenium and silica sol leaf surface barrier. The present invention also provides a leaf surface barricading method for accurately controlling cadmium ab- sorption and transport related gene expression in rice. By applying the leaf surface barrier, the silica sol or the composite selenium and silica sol leaf surface barrier having a particular atomization degree and a particular con
