在海洋光合作用和初级生产力的现场观测中,甲板模拟培养所采用的培养器,已报道的有许多类型,但大都是静态培养,这有不足之处。1)水样中的浮游植物细胞感光强弱不均匀,甚至会有光照死角;2)浮游植物细胞在行光合作用期间,因水样静止使营养盐补给状况不良,特别在营养盐作为限制因子的海域尤为明显,其结果使光合作用速率降低。Steemann Nielsen试图改变上述状态,曾制做过一种转动式培养器,使培养物产生搅动。但该培养器仅从一个侧面透光,故只可用人工光源而无法在自然光下开展工作;
In field observations of ocean photosynthesis and primary productivity, there are many types of incubators that have been reported for simulating deck cultivation, but most are static cultures, which has its drawbacks. 1) Phytoplankton cells in the water sample are not sensitive to light intensity or even light dead angle; 2) During phytoplankton cell photosynthesis, nutrient supply is not good due to water quiescence, especially nutrient salt as a limiting factor Of the sea area is particularly evident, the result of which is a decrease in the rate of photosynthesis. Steemann Nielsen tried to change that state by creating a rotating incubator that stirs the culture. However, the incubator only transmits light from one side, so only artificial light source can be used to work under natural light.
