三、营养元素在水中浓度的适宜性除了不同营养元素在水体中的相对比例与藻类生长存在密切关系外,各元素在水体中的含量(浓度)是否适宜也至关重要。营养元素含量太低,不能满足藻类的吸收需要,光合作用速率达不到满意的效果;反之,施加过量的营养元素,当光合作用速率达到最大时,营
Third, the suitability of nutrient concentrations in water In addition to the relative proportions of different nutrients in the water and algae growth are closely related to the various elements in the water content (concentration) is also very appropriate. Nutrient content is too low, can not meet the absorption needs of algae, photosynthesis rate of less than satisfactory results; the other hand, the application of excessive nutrients, when photosynthesis rate reached the maximum, Camp
