摘要
1996～1999年连续4年对南方抛秧稻田杂草发生规律及化学除草技术进行了研究。结果表明 :抛秧田杂草发生早、快、多 ,危害较移栽稻田严重 ,容易造成草荒。抛秧田除草要求除草剂的安全性更高、除稗效果更好。苯噻酰·苄WP用于抛秧田除草具有安全、高效、广谱、使用方便等特点 ,水稻增产明显 ,值得进行大面积示范和推广。
The weeds occurrence rule and the chemical control technolegy in throw seeding fields in south-china were studied in 1996～1999.The results showed that the weed occurred more earlier,fast,dense in throw seeding fields and more sreious harmful to rice and more seurited.Effectual herbicides were needed in throw seeding fields.Mefenacet·bensulfurou-mthyl WP used in the throw seeding field had characteristics of safety,hight effect,convenience. It markedly made rice yield increased and it is wortha to be use in large area.
