摘要
本文基于物理试验对不同的土壤水分运移模型进行适用性评价,建立最适宜的负压灌溉土壤水分运移数值模型,分析了不同土质条件下负压灌溉的土壤水分运移范围、强度与均匀性等规律,为完善负压灌溉理论、优化负压灌溉技术提供参考。
The applicability of different soil moisture migration models is evaluated based on physical test,thereby obtaining the most suitable negative pressure irrigation soil moisture migration numerical model in the paper. The model is adopted for analyzing soil moisture migration law scope,strength,evenness and other laws by negative pressure irrigation under different soil conditions,thereby providing reference for perfecting negative pressure irrigation theory and optimizing negative pressure irrigation technology.
