| 向日葵列当是一种寄生性杂草, 严重影响向日葵的产量?为了有效防控田间向日葵列当的危害, 本研究以抗除草剂向日葵品种为材料, 在呼和浩特市武川县上乌兰村和乌兰察布市四子王旗公合成村研究不同剂量甲氧咪草烟滴灌处理对向日葵列当的防效?结果显示, 甲氧咪草烟处理后, 降低了向日葵列当的寄生率?寄生强度和寄生程度, 增加了向日葵的产量?经过45.00?22.50 g/hm2和11.25 g/hm2甲氧咪草烟处理后, 处理后20 d时上乌兰村向日葵列当的防效分别为100%?100%和93.32%, 40 d时分别为100%?97.60%和82.35%, 60 d时分别为71.50%?31.40%和14.76%; 对公合成村向日葵列当的防效在20 d时分别为100%?100%和100%, 40 d时分别为100%?99.31和96.29%, 60 d时分别为78.81%?43.31%和11.47%?45.00?22.50和11.25 g/hm2甲氧咪草烟处理后, 上乌兰村向日葵产量分别比对照增加了72.73%?61.26%和13.83%, 公合成村的产量比对照分别增加了70.68%?84.04%和61.89%?综上, 45.00 g/hm2甲氧咪草烟处理对向日葵列当的防效持续时间较长, 同时增产效果最高? |

| Orobanche cumana is a parasitic weed that seriously affects the yield of sunflowers. This study investigated the effectiveness of imazamox treatment in controlling O.cumana using herbicide-resistant sunflower variety as test material, with different dosages applied via drip irrigation in Shangwulan village and Gonghecheng village. The results showed that imazamox treatment reduced the parasitism rate, intensity, and degree of O.cumana while increasing sunflower yield. With imazamox treatments at dosages of 45.00, 22.50 g/hm2, and 11.25 g/hm2, the control effects in Shangwulan village were 100%, 100%, and 93.32% at 20 days, 100%, 97.60%, and 82.35% at 40 days, 71.50%, 31.40%, and 14.76% at 60 days, respectively. In Gonghecheng village, control effects were 100%, 100%, and 100% at 20 days, 100%, 99.31%, and 96.29% at 40 days, 78.81%, 43.31%, and 11.47% at 60 days, respectively. Additionally, sunflower yield increased 72.73%, 61.26%, and 13.83% in Shangwulan village and increased 70.68%, 84.04%, and 61.89% in Gonghecheng village, respectively, compared to the control. In summary, imazamox at 45.00 g/hm2 provided prolonged control of O.cumana and increased sunflower yield. |
