【摘要】 针对绿地面积的大幅增加和水资源紧缺的严重问题。研究在不同供水条件下,城市绿地典型灌木金叶女贞光合特性的响应。结果表明:金叶女贞的光合特性随着水分胁迫加剧呈现出递减的趋势,但从农业节水的角度考虑,认为土壤水分为田间持水量(Fc)的75%～85%时是最优含水量。更多还原

【Abstract】 In this paper,for the substantial increase in green area and the serious problem of water shortage.The response of photosynthetic characteristics for Ligustrum vicaryi,a typical shrub in urban green land,in different water conditions is studied.The results showed that photosynthetic characteris-tics of Ligustrum vicaryi decreases when water stress increases.The optimal water content is at soil mois-ture of 75%-85% Fc from agricultural water conservancy perspective.更多还原
