Summer corn weeding should pay attention to what?

What should we pay attention to when weeding summer corn? Please introduce that it is more difficult to control weeds in corn field under the condition of no-tillage and direct seeding in summer, first of all, because the shielding of wheat straw and wheat stubble reduces the control effect of herbicides, and secondly, the one-time "sealing" effect of weeds left over in wheat fields is not ideal. When chemical weeding is carried out in the land covered with wheat stubble and straw, the amount of water should be increased to ensure that the solution can reach the surface through the straw mulch. The land with weeds left over from the wheat field can be eliminated by the method of "blocking and combining". For the plots with serious weeds left behind in the wheat field, the weeding strategy of "one cover and one kill" can be adopted before sowing, and the weeding strategy of "first sealing and killing" can be adopted for the plots with few weeds left after sowing and the seedling stage of corn. For the plots where weeds are distributed in strips in wheat fields, the weeding strategy of "killing" before "sealing" can be adopted.
