| 摘 要： | 为了寻找高效安全的微生物除草剂,本研究以天然存在的黏质沙雷氏菌Ha1菌株为试验材料,采用发酵液喷施法和颗粒剂封闭法(填埋法和撒施法)对玉米田常见杂草进行了室内活性测定。发酵液喷施法、颗粒剂填埋法和撒施法对杂草的鲜重防效分别为47.88%,70.63%和76.82%。发酵液喷施法和颗粒剂封闭法均能有效防除杂草,颗粒剂封闭法优于发酵液喷施法,颗粒剂撒施法优于填埋法。

| Abstract: | In order to find efficient and safe microbial herbicides, indoor activity of the naturally occurring Serratia marcescens Ha1 strain on common weeds in maize field by fermentation broth spray method and granule sealing method (landfill method and spreading method). The fresh weight control efficacies of fermentation broth spray method, granule filling method and spreading method on weeds were 47.88%, 70.63% and 76.82%, respectively. Both the fermentation liquid spraying method and the granule sealing method can effectively prevent weeds. The granule sealing method is superior to the fermentation liquid spraying method, and the granule spraying method is superior to the landfill method. |
