摘　　要：本试验以绿萝为试验材料,研究二溴海因对水培绿藻的抑制作用,并分析了二溴海因在抑藻过程中对营养液和植株生长的影响。结果表明,在不同浓度处理下,二溴海因均能抑制藻类的生长;酸性和中性条件下,二溴海因浓度为50mg/L时抑制效果最好,碱性条件下抑藻最佳浓度为30mg/L;二溴海因处理对绿萝植株生长和营养液溶解氧影响不明显,对营养液电导率有一定的作用,但不超过植物正常生长所适宜的范围。Take the scindapsus for the experiment material, study on the inhibition of DBDMH to green algae by indoor hydroponic experiments, and the influence of DBDMH on nutrient solution and plant growth in the process of the experiment was analyzed. The result indicated that DBDMH was able to inhibit the growth of algae no matter what concentration it was; under the acidic and neutral conditions, It was the DBDMH concentration of 50 mg/ L that the inhibitory effect reached the best level, but under the alkaline conditions, the best was 30 mg / L ; the DBDMH processing had no significant effect on the plant growth and the dissolved oxygen of the nutrient solution and played a certain role in the conductivity of the nutrient solution, but it didn＇t exceed the appropriate scope of the normal plant growth.
