土壤入渗特性的季节性变化对灌溉效果的影响研究
- Title:
- Research of Influence of Seasonal Change of Soil Infiltration Characteristic on Irrigation Effects
- Keywords:
- soil infiltration; irrigation effect; variability of soil infiltration characteristic; irrigation efficiency; stockpile efficiency of irrigation water
- 摘要:
- 依据耕作土壤年内不同季节的土壤入渗试验和大田灌水试验,采用试验研究与计算机模拟相结合的方法,分析讨论了耕作土壤入渗特性随季节的变化特性及土壤入渗特性变化对农田灌溉的灌水效率、储水效率、灌水质量的影响,并提出了现行灌溉系统下切实可行的提高灌水效率、储水效率、灌水质量的措施.本研究成果将为节水灌溉技术参数的确定提供依据,并可为农田灌溉用水管理提供指导.
- Abstract:
- Based on field infiltration and irrigation experiments of farming soil during different irrigation seasons,through the method of experimental research combined with computer mathematical simulation the variability of soil infiltration characteristic with irrigation seasons and the influence of seasonal change of soil infiltration characteristic on irrigation efficiency,stockpile efficiency of irrigation water and irrigation quality are analysed and discussed,and some practicable measures by which irrigation efficiency,stockpile efficiency of irrigation water and irrigation quality are improved are put forward.The results can be used for determinning saving irrigation technique parameter and for guiding irrigation management.
