The effect of recycling storm water with high chloride concentrations on shrub willow growth was examined in a ten-week greenhouse study. Three willow varieties Salix miyabeana (SX64), Salix purpurea (9882-34), and Salix sachalinensisxSalix miyabeana (9870-40) were grown in organically-amended Solvay waste, and irrigated with five storm water concentrations containing 163, 325, 813, 1625, and 8125mgCl(-)L(-1) and a tap water control. Stomatal conductance values responded most rapidly to stress (after 4.5weeks), but height and leaf length measurements, which revealed signs of stress after 6 and 7weeks, might be more practical stress indicators for large-scale plantations. Even though variety 9870-40 was most sensitive with increasing concentrations of Solvay storm water, this variety had the greatest ET values during the ten-week trial. Storm water with concentrations up to 1625mgCl(-)L(-1) had no short-term effects on biomass accumulation and evapotranspiration.
在为期十周的温室研究中，研究了高氯浓度的雨水回收对灌木柳树生长的影响。三种柳树品种，即 Miyabe 柳树（SX64）、紫柳（9882-34）和杂交柳（9870-40），在经过有机改良的 Solvay 废物中生长，并分别用含有 163、325、813、1625 和 8125mgCl(-)L(-1)的五种雨水浓度和自来水对照进行灌溉。气孔导度值对胁迫的响应最快（在 4.5 周后），但高度和叶片长度的测量值在 6 周和 7 周后才显示出胁迫迹象，因此对于大规模种植园来说，这些测量值可能是更实用的胁迫指标。尽管品种 9870-40 对 Solvay 雨水浓度的增加最敏感，但在十周的试验中，该品种的 ET 值最大。浓度高达 1625mgCl(-)L(-1)的雨水对生物量积累和蒸散没有短期影响。
