柽柳对滨海盐渍土的改良作用及其应用

Soiled Modification and Application of Tamarix Chinensis on the Saline Soil

以山东省威海市高区环海路上的柽柳为研究对象,在其根系附近采集实验组土样并在其周围的空白地面上采集对照组土样,测定几组能够说明其土质的数据,如土壤中生物的分类与计数、有机质的含量、土壤的pH值、土壤中空气的体积以及土壤颗粒的贮水能力。通过将实验组与对照组的比较,分析得出在滨海盐渍土上栽植柽柳不但可增加土壤中微生物的含量,而且可增加土壤中的空气和有机质的含量,提高土壤颗粒的贮水能力,还可降低土壤的pH值,增加观赏性。因此,根据所测的各项指标得出柽柳对滨海盐渍土具有改良作用的结论,为推动与利用柽柳在滨海盐渍土上的种植提供理论依据。

This research was concentrated on Tamarix chinensis, which grew on the sea road of high - tech industrial development zone in Wei- hal. The soil samples of the experimental group and the control group were picked up from the root system of Tamarix chinensis and the blank space around there. Then several sets of data was detected,such as the number and the kinds of micro- organisms in the soil,the content of organic matter, the pH value,the volume of air, the capacity of storage water, and so on. Though the comparison between the experimental group and the control group, it was proved that planting Tamari chinensis on the saline soil not only could increase the number of the soil micro- organisms, but also could increase the volume of air, the content of organic matter, and lower the pH value, increase in ornamental. According to those data detected in this researeh,the conclusion of Tamarix chinensis had a remarkable effect that could be got,and the research provided theoretical basis to promote and utilize the coastal saline soil by Tamarix chinensis at the same time.
