Sorghum is a corp which is sensitive to herbicides. In order to select herbicides which are suitable for sorghum,‘Jiza 210’was used in the field experiment to preliminary screening of closed herbicides. The results showed that different kinds of herbicides and content produced different degrees of phytotoxicity, and the germination rate,plant height, yield and other indicators were affected. 38% atrazine or 96%S-metolachlor used after sowing and before seedlings were safe, which have not obvious phytotoxicity to the growth of sorghum.
