不同水分环境对金叶女贞生长影响的研究

Study on effect of different water environment on the growth of Ligustrum vicaryi

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。

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 characteristics of Ligustrum vicaryi decreases when water stress increases. The optimal water content is at soil moisture of 75% -85% Fc from agricultural water conservancy perspective.
