Abstract:

在实验室条件下,设置不同的N、P浓度,研究单因子(P:30μmol/L,N:0~500μmol/L和N:500μmol/L,P:0~30μmol/L)对浒苔(Enteromorphaprolifera)生长的影响。结果表明:在高N、P浓度(N:500μmol/L,P:30μmol/L)条件下浒苔生长态势最好,具有较高的相对生长率(0.451)。添加N可以明显促进浒苔的生长,而且随着添加N浓度的提高促进作用增强,浒苔的相对生长率有较大幅度提高。添加P对浒苔的生长也具有一定的促进作用,但促进作用不如添加N的明显;随着添加P浓度的提高,浒苔的相对生长率提高幅度不大,这说明浒苔生长对N变化更为敏感。
