摘要
以一年实生野扇花苗为材料,研究其在不同pH值土壤中的生长状况及对土壤的改良作用。结果表明:野扇花在中性至偏碱性的土壤中,地上部分生物量积累优于酸性土壤;在酸性条件下,虽然生物积累量较中性至碱性土要差,但仍可在强酸性环境中生长。野扇花可以改良土壤中大量元素的含量,对酸性土壤有提升其pH值的作用。
The growth of Sarcococca ruscifolia Stapf in different soil pH and its function in soil improvement were Studied out using the annual seedlings.Results showed that growth parameters including seedling height,ground diameter,root/shoot ratio reflected superior accumulation of biomass in neutral or to partial alkaline soil in comparison with that in acid soil.According to the biochemical index,this species could survive in strong acid environment since it might grow.Based on measurements of physicochemical property after three years,it can conclude that Sarcococca ruscifolia Stapf may improve major element contents in soil,and enhance soil pH.
