砂引草对滨海盐渍沙质土壤改良作用的研究

Application of Messerschmidia sibirica Linn. on Sandy Soil Salinity

以山东省威海市高区国际海水浴场的砂引草种群为研究对象,在其根系附近采集实验组土样并在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,如土壤中空气的体积、土壤储水能力、有机质含量、土壤pH值等。通过将实验组与对照组进行比较,分析得出在滨海盐渍沙质土生长的砂引草可增加土壤中的空气和有机质含量,提高土壤颗粒的贮水能力,降低土壤pH值,同时还有绿化美观的效果,可为滨海的土质改良和绿化提供帮助。

This research was concentrated on Messerschmidia sibirica Linn.,which grew on the beach of international sand beach at Weihai City,Shandong Province.The soil samples of the experimental group and the control group were picked up from the root system of Messerschmidia sibirica Linn.and the blank space around there.Then several sets of data was detected,such as the volume of air,the capacity of storage water,the content of organic matter,the pH value,and so on.Though the comparison between the experimental group and the control group,it was proved that Messerschmidia sibirica Linn.planting on the sandy soil salinity could increase the volume of air,the content of organic matter,and lower the pH value.There was also the effect of green beauty,so it could help to coastal soil improvement and greening.
