摘要
铜绿微囊藻(Microcystis aeruginosa)是国内湖泊蓝藻水华中的常见藻种,在实验室光照培养箱中对其进行培养,使用GER1500光谱仪在自然光照下采集藻液的光谱数据,研究了不同磷浓度培养基条件下铜绿微囊藻的生长规律以及培养周期内藻液的光谱变化特征,结果表明,其他条件相同情况下,低磷浓度(≤10μg.L-1)成为铜绿微囊藻生长繁殖的限制性因素,随着培养时间的不断增加,铜绿微囊藻藻液的光谱曲线在550,610,660,700~710,760nm附近等一些波段呈现出明显的变化特征。
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. Spec-troscopic 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 phos-phorus concentration (≤10μg·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.
