水培中抑制绿藻生长的方法研究

摘要

对水培花卉中易产生绿藻问题的研究结果表明，1％CuSO4抑藻效果最好，其次是0．1％CuSO4、0．5％CuSO4、活性炭2g；活性炭3个处理的新根生长情况明显优于磁铁3个处理，而CuSO4 3个处理几乎无水培根产生，叶片甚至出现枯死现象；CuSO4 3个处理营养液pH相对稳定，活性炭3个处理、磁铁3个处理pH值随时间经历了一个升高一降低一升高的过程。%A study was held in order to resolve the problem of green algae in hydroponics flower,the results showed that 1% CuSO4 inhibited the growth of algae best, followed by 0.1% CuSO4, 0.5 % CuSO4, activated carbon 2 g; the new root growth of 3 activated carbon treatments were better than 3 magnet treatments, the 3 CuSO4 treatments produced almost no hydroponic roots, and dead leaves appeared; the pH of of nutrient solution for the 3 CuSO4 treatments were relatively stable, the pH of 3 activated carbon treatments and 3 magnet treatments experienced a rise - reduce - increase process over time.
