藕田水绵防除药剂初步筛选

Preliminary Screening of Chemical Reagents for Controlling Spirogyra communis in Lotus Fields

为了筛选可用于抑杀藕田水绵(Spirogyra communis)的有效药剂,测试了7种药剂对水绵的抑杀效果和对莲藕的安全性。结果表明:氯溴异氰尿酸对水绵的抑制效果最好,其次是生石灰、灭苔护草胺和扑草净,对水绵抑制率均在60%以上。氯溴异氰尿酸对莲藕的安全性最高,其次是灭苔护草胺、生石灰、硫酸铜、苔藻净、青苔净,扑草净最低。

To screen out the chemical agents which are effective in inhibiting or killing Spirogyra communis in lotus field,we tested the inhibiting effects of seven reagents to Spirogyra communis and the security to lotus.The results showed that chloroisobromine cyanuric acid had the best inhibiting effect,followed by quicklime,out moss guard grass safety and prometryn,with all the inhibiting effects above 60%.The chloroisobromine cyanuric acid exhibited the highest security to lotus,followed by out moss guard grass safety,quicklime,copper sulfate,Taizaojing,Qingtaijing and prometryn in sequence.
