Summary

本文介绍了一个使用水力特性仪器对土壤样品进行的简单蒸发实验。通过有效的方法,可以在几天内进行测量,以生成高质量的数据。

Transcript

在可持续土地生态系统实验室,我们的研究重点是为影响土地生态系统(包括农田和草原)的问题寻找可持续的解决方案。解决这个复杂的问题涉及研究土壤健康,这是所有农业用地生态系统的关键部分。获得延伸到干式范围的土壤保水曲线是一项挑战。

目前,有必要将该实验的数据与另一台仪器上的其他数据相结合。对于某些研究目标来说,这可能不太理想。这里的主要优点是仪器可以用相对较少的用户时间和输入产生数据量。

与尝试创建数据点较少的土壤保水曲线的其他技术相比,该仪器提供了更精确的数据。
