摘要
选择硫酸铜、扑草净以及肉桂酸为控藻药剂,以常见的丝状藻-水绵为受试对象,比较了三种药剂的控藻效果.研究结果表明,三种药剂的施用对水绵生长、代谢及抗逆功能均造成了影响,但影响程度因药剂类型、药剂浓度及施用时间而异.相同浓度条件下,硫酸铜、扑草净的控藻效果均优于肉桂酸,但硫酸铜的施用会造成环境累积和生物放大等危害.结合控藻有效性、安全性和经济性,选择1 mg/L扑草净为最优方案.
Abstract
Copper sulfate,prometryn and cinnamic acid were selected for spirogyra control.The experimental results showed that the use of three did affect the growth,metabolism,activities of antioxidative enzymes and micro-structure of spirogyra.The effect of chemicals on spirogyra depended on chemical,dosage and exposure time.Under the same dosage,the effect of copper sulfate and prometryn were stronger than that of cinnamic acid.Integration of effective,safe and economic factors,1 mg/L of prometryn is recommended for spirogyra control.
