笔者以晋北应县多年生枸杞地的盐碱土为研究对象,按土壤深度和行间变化采集土壤样品,运用数理统计方法分析土壤基本情况,探讨盐碱分布格局. 结果表明:在试验地内,土壤含水率偏低,pH值为8.56,为强碱性土质. 与全国土壤背景值相比,枸杞试验地内的有效Fe含量积累现象极为显著. 随土壤深度的变化,有效Fe含量无明显差异;但离植株不同远近,会影响土壤有效Fe含量,并呈现升高趋势. 随着土层深度的增加,枸杞地土壤pH值和含水率逐渐上升,电导率变化不明显;在远离植株的过程中,pH值、电导率和含水率均在20 cm~30 cm处出现高峰值,然后又下降. pH值和电导率均低于空白对照. 整体可以看出,种植枸杞对应县盐碱地有改良作用.

The saline-alkali soil of perennial Lycium chinense in Ying county in north Shanxi province as the research object, we took soil samples by soil depth and leading change.The basic situation of the soil was analyzed by mathematical statistics to explore the saline-alkali distribution pattern.The results showed that in the field, soil moisture content was low, the pH value was 8.56, as the alkaline soil.Compared with the national soil value, available Fe accumulation phenomenon in Lycium chinense field was remarkably effective.As the change of soil depth, available Fe content had no obvious difference.Distance from plant would affect the soil available Fe content, and showed a trend of rise.With the increase of soil depth, soil pH and moisture content in Lycium chinense field was gradually rising, conductivity change was not obvious.Far away from the plant, pH value, conductivity and moisture content were at the peak between 20 cm~30 cm, and then fell.pH value and conductiv-ity were lower than CK.Overall, plantation of Lycium chinese could improve saline-alkai soil.
