玉米植株对降雨再分配过程的影响
Study on the Effect of Maize Plants on Rainfall Redistribution Processes
摘要
Abstract
[Objective] The purpose of this study was to investigate the rainfall redistribution processes through maize canopy. [Method] Rainfall simulator was used to measure mature maize canopy interception, throughfall and stemflow based on the actual rainfall intensity. [Result] The averages of throughfall, stemflow and canopy interception account for 7.5%, 28.8% and 63.7% of the total precipitation, respectively. Canopy interception, stemflow and throughfall were statistically significantly positive correlated with rainfall intensity, and canopy interception and stemflow were statistically significantly positive correlated with leaf area, while throughfall was statistically significantly negative relationship with leaf area.[Conclusion]Under different rainfall intensities, canopy interception capacity was different, canopy and stemflow can guide a part of total rainfall, reduce the amount of rainfall arrived on the soil and influence runoff. Compact and practical equations built in this study has provided a theoretical basis for farm land soil erosion control.关键词
