为确立噁草酮防除直播稻田杂草稻的施用技术,南京农业大学杂草研究室/江苏省杂草防治技术工程中心研究人员通过温室盆栽试验比较了噁草酮在不同土壤水分环境下对栽培稻的安全性及对杂草稻的防效,并在大田中比较了不同直播方式下其对杂草稻的防效及栽培稻产量的影响。结果表明,透气条件下,噁草酮对栽培稻的药害最低,但对杂草稻的防效也较差;饱和水分条件下对
In order to establish the application technology of oxadixone to control weedy rice in direct-seeded rice fields, researchers at Weed Research Office of Nanjing Agricultural University / Weed Control Technology Engineering Center of Jiangsu Province compared the effects of oxadiazonol on cultivation of cultivated soil under different soil moisture conditions The safety of rice and its control effect on weedy rice. The effects of different direct seeding methods on the control effect of weedy rice and the yield of cultivated rice were also compared in field. The results showed that under the aeration conditions, oxalicotine had the lowest phytotoxicity on cultivated rice, but its weed control effect was weaker. Under saturated water conditions
