中文摘要：

为研究土壤压实对陆稻根系生长的胁迫作用，关键是确定土壤中陆稻根系生长的参数变化。制作水一土分层装置便于统计根系穿出土壤层的时间，从而比较出土壤压实对根系轴向生长速度的影响。基于VisualC＋＋6．0开发环境和OpenGL图形库对土壤压实下，陆稻根系进行可视化模拟，为研究不同土壤压实对植物根系生长的影响提供了一种新方法。

英文摘要：

As for studying the stress effect of soil compaction on the root growth of upland rice, the key is to determine root growth parameter changes of upland rice in soil. Making water - soil layered device is convenient to count the time when the roots traverse through the soil layer, and compare the impact of soil compaction on the axial growth rate of root system. The visual simula-tion of upland rice root system was conducted under the soil compaction condition based on the Visual C ＋ ＋ 6.0 development envi-ronment and the Open G L graphic library, which provided a new method for studying the effects of different soil compactions on plant root growth.
