Herbicides with drip irrigation (chemigation) could control the herbicides application accurately as technology, and reduce harm to humans environment. However, herbicide concentration is not consistent in advancing process along tape of different lengths, which only influences crop growth results residue. In this study, environmental effects chemigation were discussed, potassium permanganate was used replace herbicides, a laboratory test conducted determine best duration. Based on result, maize field experiment under plastic mulch carried out compare index, yield residue for determining optimal mode. The result shows that there no significant difference uniformity among treatments, but leaf area index (LAI), yield, double-ear rate continuous (CA) higher than those periodic (PA) (NA) significantly. One month after application, acetochlor two modes less 1%, would cause pollution surrounding And linear regression relationship between length duration same dosage.
