摘要
研究了温度、光照强度及Ｎ、Ｐ浓度与水网藻生长的关系．结果表明，水网藻能在较大的温度范围（１０～３１℃）、光照强度（３００～５３００Ｌｘ）和Ｎ浓度（１．０～８４．０ｍｇ·Ｌ－１）和Ｐ浓度（０．０５～３．７２ｍｇ·Ｌ－１）等条件下生长．最适生长温度为２５℃，当光照强度大于１３００Ｌｘ，Ｎ、Ｐ含量分别为１６．８～５０．４和０．７４４～２．２３ｍｇ·Ｌ－１时，水网藻生长良好．低温有利于水网藻忍耐低光照和低Ｎ低Ｐ．
Studies on the relationship of
Hydrodictyon reticulatum growth with temperature, light intensity and nutrient concentrations
showed that H.reticulatum could tolerate a wide range of temperature (10～35℃), light
intensity (300～5300Lx), and nitrogen and phosphorus concentrations (1.0～84.0mg N·L -1
and 0.05～3.72mg P·L -1 respectively). Its optimal growth was at 25℃,≥1300Lx, 16.8～
50.4mg N·L -1 , and 0.744～2.23mg P·L -1 . Low temperature was beneficial to
H.reticulatum to tolerate low irradance and low nitrogen and phosphorus concentrations.
