- 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；3 g/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。
- Abstract:
- 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 under 20℃/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 3 g/300mL neither affect Echinocactus grusonii normal root and grow，also had good control effect to algae.
