安融樂與除草劑混用對小麥田多花黑麥草的防除效果研究

摘要 為評價安融樂與除草劑混用對小麥田惡性雜草多花黑麥草的防除效果，開展了田間試驗。結果表明，安融樂可以提高除草劑的速效性。藥后15 d，5%唑啉草酯乳油用量減少300 mL/hm²后，加入安融樂使多花黑麥草達到5級藥害癥狀的比例增加55.56%～61.69%；安融樂與5%唑啉草酯乳油+50%異丙隆可濕性粉劑+18%氟唑磺隆·炔草酯可分散油懸浮劑混用達到5級藥害癥狀的雜草比例比除草劑單用增加125.35%～141.95%；安融樂與5%唑啉草酯乳油+30 g/L甲基二磺隆可分散油懸浮劑+18%氟唑磺隆·炔草酯可分散油懸浮劑混用達到5級藥害癥狀的雜草比例比除草劑單用增加21.42%～35.82%。藥后45 d，雜草株防效和鮮重防效均達到最高。安融樂能有效提高除草劑對多花黑麥草的作用速度及防除效果，可以進一步示范和推廣。

Abstract A field experiment was conducted to evaluate the control effect of the mixture of AnnGro and herbicides on the malignant weed Lolium multiflorum in wheat fields. The results indicated that AnnGro could improve the quick efficacy of herbicides. At 15 days after a reduction of 300 mL/hm² in the dosage of 5% imidacloprid EC， the addition of AnnGro increased the proportion of grade 5 pesticide damage symptoms in Lolium multiflorum by 55.56%-61.69%;the proportion of weeds with grade 5 pesticide damage symptoms achieved by the mixture of AnnGro and 5% imidacloprid EC+50% isoproturon wettable powder+18% fluazuron · ethyne ester dispersible oil suspension agent increased by 125.35%-141.95% compared to the single use of herbicides;the proportion of weeds with grade 5 pesticide damage symptoms achieved by mixing AnnGro with 5% imidacloprid EC+30 g/L methyldisulfuron dispersible oil suspension agent+18% fluazuron · ethyne ester dispersible oil suspension agent increased by 21.42%-35.82% compared to using herbicides alone. After 45 days of treatment， the weed control effect and fresh weight control effect reached the highest. AnnGro could effectively improve the rate of action and control effect of herbicides on Lolium multiflorum， and could be further demonstrated and promoted.

安融樂是由南非西北大學發明的從大豆中提取的新型生物增效助劑，在1947年南非第36號法案中作為農藥助劑注冊，主要成分為卵磷脂和維生素E（www.AnnGro.Com）。安融樂在促進肥料、殺菌劑、殺蟲劑、除草劑、生長調節劑等吸收，促進作物生長和提高植物抗病性上的應用研究較多。研究表明，安融樂添加到種子肥料中可以促進玉米根和胚芽鞘的生長，提高玉米產量^［1］。……
