Microcystis aeruginosa is one of the most common species in the algae-bloom events of domestic lakes. Illumination incubator was used to cultivate M. aeruginosa under conditions of different phosphorus concentrations in the laboratory. Spectroscopic data of culture solutions were collected by GER1500 spectrometer under the sunlight. The study focused on the growth rhythm of M. aeruginosa and the characteristics of spectral variation in the culture solutions. The results showed that low phosphorus concentration (< or =10 microg x L(-1)) is a restricting factor for the growth and reproduction of M. aeruginosa. Moreover, the reflections of spectrum from culture solutions of M. aeruginosa showed significant changes along with cultivation period, such as at the wavelengths of 550, 610, 660, 700-710 and 760 nm.
铜绿微囊藻是国内湖泊藻类水华事件中最常见的物种之一。在实验室中，使用光照培养箱在不同磷浓度条件下培养铜绿微囊藻。通过GER1500光谱仪在阳光下收集培养液的光谱数据。该研究聚焦于铜绿微囊藻的生长节律以及培养液中光谱变化特征。结果表明，低磷浓度（≤10微克×升⁻¹）是铜绿微囊藻生长繁殖的限制因素。此外，铜绿微囊藻培养液的光谱反射随培养时间呈现出显著变化，例如在550、610、660、700 - 710和760纳米波长处。
