摘　　要：该文利用单齿螺对坛紫菜贝壳丝状体附着硅藻进行了去除研究,设置了7个梯度进行单齿螺对附着硅藻的去除试验,设置了5个梯度进行了单齿螺对清洗后贝壳丝状体的维持试验,结果显示:附着硅藻被清理干净的天数与螺的个数在一定范围内成反比趋势,螺越多,吃的速度越快,所用时间越短;每平方米投放144个单齿螺比较合适,能够在短时间内清除苗壳表面的附着硅藻,同时能够节约成本;每平方米放36个单齿螺能够达到维持苗壳表面干净的效果。In this paper, the removal of attached diatoms from conchocelis of P. haitanensis was studied by M. labio. Seven gradients were set to remove attached diatoms from shell filaments of P. haitanensis. Five gradients were set to maintain conchocelis after cleaning by M. labio. In a certain range, the more snails there are, the faster they eat and the shorter the time they take. 144 M. labio per square meter were suitable for removing the attached diatoms on the surface of the conchocelis in a short time. 36 M. labio per square meter could achieve the effect of maintaining the clean surface of the seedling shell.
