摘要: 通过马氏珠母贝与羊栖菜的混养实验,测定了贝释放的氮磷含量及羊栖菜对贝释放氮磷的吸收量,比较了实验组(有贝)、模拟组(无贝)与对照组之间羊栖菜的生长差异,并进一步阐述了羊栖菜对马氏珠母贝代谢产物的吸收速率与去除效率。结果表明:实验组中,马氏珠母贝释放的氮以及羊栖菜吸收的氮均以NH+4-N为主;对4种代谢产物NH+4-N,NO-3-N,NO-2-N,PO43+-P,马氏珠母贝的释放比例为27:21:1:18,而羊栖菜的吸收比例为17:12:1:2.6。方差分析结果表明,实验组与模拟组相比,藻对氮磷的吸收速率具有明显的促进作用(P<0.05);各组间生长情况的Duncan’s多重比较表明,各组羊栖菜日增质量与日增长值均存在显著性差异(P<0.05),大小顺序为:实验组>对照组C>模拟组>对照组A>对照组B。这表明马氏珠母贝的代谢产物能够促进羊栖菜生长。Abstract: During the polyculture of shellfish Sargassum fusiforme and algae Pinctada martensii,we compared the growth differences of algae in the experimental group with shellfish,the simulation group without shellfish and the control group by measuring the amount of nitrogen and phosphorus released by the shellfish and absorbed by the algae.Furthermore,the removal rate and the absorptivity of the algae for the metabolic products of the shellfish were also determined.Results showed that NH+4-N is the main form of nitrogen which P.martensii released and S.fusiforme absorbed.Four metabolites are NH+4-N,NO-3-N,NO-2-N and PO43+-P,and their release ratio from the shellfish is 27:21:1:18 while the algae absorption ratio 17:12:1:2.6.Analysis of variance showed that algae in the experimental group played a significant role in promoting the absorption rate of nitrogen and phosphorus（P＜0.05） when compared to the simulation group.Meanwhile,Duncan’s multiple comparisons between the groups showed that daily weight gain and daily growth gain of S.fusiforme were significantly different among all the groups（P＜0.05） and increased in the order of the experimental group＞the control group C＞the stimulation group＞the control group A＞the control group B,which indicates that the metabolites of P.martensii can promote the growth of S.fusiforme.This research provides a theoretical basis for optimizing the polyculture density of P.martensii and S.fusiforme.
