摘要:
利用德国产TRIME-T3测量系统测定土壤电导率的相关值及土壤含水率。通过对果园土壤电导率相关值的研究，得到了TDR-LEVEL在垂直方向上的分布特征，即在0～100 cm范围内TDR-LEVEL受外界影响比较明显，分布规律性差；100～180 cm范围内土壤电导率相关值呈现出先降低后增加的分布趋势。随时间的变化，土壤电导率相关值呈现出先降低后增加的动态规律，与相对应的土壤含水量的变化趋势相反，并在TDR-LEVEL垂直方向上分布特征的基础上建立了0～30 cm内各层与0～100 cm层的经验关系模型。
Abstract:
Measure soil electric conductivity correlation and soil moisture content by the TRIME-T3 measurement system made in Germany.Distribution characteristic of TDR-LEVEL in the vertical direction through the study of orchard soil electric correlation.The result shows that there is a obvious influence by out side in the 0～100 cm layer,distribution regularity is bad.In the layer of 100～180 cm,distribution trend of soil electric conductivity correlation is descend first and then ascend.With the change of time,the dynamic regularity showed by soil electric conductivity of descend first and then ascend is opposite to the changeable trend of the corresponding soil moisture content.At the basis of distribution characteristic of vertical direction of TDR-LEVEL,experiential relation model is built between 0～30 cm layer and 0～100 cm layer.
