- 摘要:
- 20%烟嘧磺隆·莠去津油悬浮剂是新型玉米苗后茎叶处理混剂, 就其对春玉米安全性及对杂草的防除效果进行了试验。 结果表明:在玉米苗后 3～ 5 叶期喷雾, 剂量为240～ 300 g·hm -2 , 施药后 30 d 对杂草的综合防效为 93.3%～97.2%, 增产幅度为 20.5%～ 21.7%。
- Abstract:
- 20% Nicosulfuron.Atrazine OF is a new herbicide applied to maize field.It was chosen to control weeds in maizefield and its safety was studiedin thisexperiment.The results showed that application of 20% Nicosulfuron.AtrazineOF at240～ 300 g·hm-2 could control weed and it was safety .The optimum application time was during 3～ 5 leaf stage.The totalcontrol effect were 93.3%～ 97.2%in 30 days after application.The increasing yield ranged from 20.5% to 21.7%.
