Nutrient Uptaking and Growth Performance of Ulva prolifera
摘要
Abstract
Objective]The nutrient uptaking and growth ofUlva prolifera was measured in the laboratory,in order to provide a reference for management and utilization ofUlva prolifera.[Methods]The concentrations of DIN and PO3-4 -P in water under two nutrient concentration were tested by national standard.The weight of algae under different temperature and nutri-ent concentration was timely measured.[Results]The results showed that the maximum per-centages of DIN and PO3-4 -P absorbed byU.prolifera were 62.2% and 27.5%,and the up-taking rates were 0.022 mg N/(g·h)and 0.006 mg P/(g·h).U.prolifera grew fast under various experimental conditions.The max SGR was 9.44% with the doubled weight after 8 d when the temperature was 15℃ and added N:P(mg/L)=3:0.3.When the temperature was 20℃ without adding chemicals,the growth was the slowest and the weight doubled after 1 3 d.[Conclution]U.prolifera showed the characteristics of high nutrients absorbance and growth rate.关键词
