phosphorus cycle

ecological kinetic models and methods of phosphorus cycle in free-water surface constructed wetlands

表面流人工湿地磷循环生态动力学模型及实现方法

Under high phosphorus level ( 375 kg/ ha), Chlb content, Hill reaction and non-cycle photophosphorylation activities of flag leaves were retarded, and these parameters showed a similar regularity change indicating they were more sensitive to phosphorus than the other parameters determined.

高施磷量（P2O5375kg/hm2）时，旗叶的叶绿素b含量（Chlb）减少、希尔反应和非环式光合磷酸化活性受到抑制，对磷肥的响应规律基本一致。

The slip viscosity can be reduced, the slip exhausting speed of bodies can be increased, and their drying cycle can be shortened, adding the sodium polyphosphate and phosphorus components.

添加多磷酸钠和含磷成分可以降低泥浆的粘度，提高坯体的排浆速度，缩短干燥时间。
