摘　　要：以2年生金琥为试材,去掉老根后进行不同温度下的水诱处理,以探究温度对水诱金琥生根的影响;水培生根后,添加活性炭和硫酸铜,研究2种方法对金琥水培过程中绿藻的控制效果。结果表明:在20℃/13℃、25℃/15℃、30℃/16℃、35℃/18℃处理下,随着温度的升高,金琥的生根时间越早,生根速度越快,根长越长;水诱金琥生根在35℃/18℃处理下,生根时间最早,根生长速度最快且最长;但在40℃/20℃和45℃/23℃处理下金琥的生根能力不及35℃/18℃,随温度升高金琥生根能力越来越差;3g/300mL的活性炭处理,既不影响金琥正常生根、生长,又有较好的防除绿藻效果。Taking biennial Echinocactus grusonii as material,it was under water-induced treatment at different temperatures after it was removed the old root,to explore the influences of Echinocactus grusonii rooting under different temperatures;added activated carbon and copper sulfate to found the control effect of green algae under two methods after Echinocactus grusonii hydroponic rooting.The results showed that the water-induced Echinocactus grusonii rooting root growth under20℃/13℃,25℃/15℃,30℃/16℃,35℃/18℃ treatments,as the temperature rose,Echinocactus grusonii rooting was earlier and faster,root length was longer;under 35℃/18℃ treatment was the earliest,fastest and longest;the Echinocactus grusonii rooting was under 40℃/20℃and 45℃/23℃treatments water-induced was less than under 35℃/18℃,as the temperature rose,Echinocactus grusonii rooting was later,root length was shorter.The Echinocactus grusonii rooting under activated carbon treatment of 3g/300 mL neither affect Echinocactus grusonii normal root and grow,also had good control effect to algae.
