摘　　要：由于目前尚没有一种除草剂获得在观赏月季田块使用的农药登记证,为了探讨在观赏月季田块进行化学除草的可行性,参照GB/T 17980.44—2000《农药田间药效试验准则（一）除草剂防治果园杂草》的方法进行了观赏月季田块杂草的化学防除试验。结果表明：高效氟吡甲禾灵、氰氟草酯2种除草剂400倍以上的稀释液对观赏月季没有药害;高效氟吡甲禾灵800倍稀释液对1年生禾本科杂草的防治效果为87.44%~91.12%;氰氟草酯800倍稀释液对1年生禾本科杂草的防治效果为80.29%~97.14%;氟磺胺草醚800倍以上稀释液对观赏月季没有药害,其800倍稀释液对观赏月季田块阔叶杂草的防治效果为83.33%~89.24%。可以看出,高效氟吡甲禾灵与氟磺胺草醚混用有降低其对1年生禾本科杂草的防治效果的趋势。There are no herbicides approved for controlling weeds in fields of ornamental Chinese rose. To explore its fea- sibility of using chemical control against weeds in this ornamental crop, we followed the guidelines of Chinese standard GB/T 17980.44--2000 to establish a chemical control experiment. Haloxyfop - r - methyl and cyhalofop butyl diluted in more than 400 eaneentrations applied in the test didn＇t cause phytotoxicity on ornamental Chinese rose; control effect of haloxyfop- r- methyl in 800 diluted concentrations against annual grmnineous weeds was 87.44% ~ 91.12%, compared with that of halofop butyl in 800 diluted concentrations of 80.29% ~ 97.14% ;fomesafen in more than 800 diluted con- eentrations didn＇t cause phytotoxieity on ornamental Chinese rose, and the control effect of fomesafen in 800 diluted con- centrations to bmadleaf weeds in the field was 83% to 89%. From the results we can see that,mix use of haloxyfop - r - methyl and fomesafen in the field has tendency of reducing the control effect against annual gramineous weeds.
