积雪和冻土的存在对农田土壤墒情有着重要的影响。积雪和冻土对于土壤墒情的保持有正作用,但相关研究主要停留在对这一现象的描述层面,其规律和机理的研究还有待加强。通过梳理相关监测试验成果,从试验环境、监测项目、监测仪器、监测方法4个方面对积雪和冻土保墒监测试验方案进行分析和设计。在分析已有试验的基础上,结合现有的研究经验,综合考虑试验的真实性、可控性和易于对比性提出3种试验设计方案。试验设计方案的提出可为进一步获取试验数据提供参考。 The presence of snow and frozen soil has an important impact on soil moisture in farmland. Snow and frozen soil have a positive effect on the soil moisture retention, but the related research mainly stays in the description of this phenomenon, and the research on its law and mechanism needs to be strengthened. Through combing the related monitoring test results, the experimental scheme of soil moisture monitoring in snow and frozen soil was analyzed and designed from four aspects of the test environment, monitoring items, monitoring instruments and monitoring methods. Based on the analysis of the existing experiments and the existing research experience, three experimental design schemes are put forward based on the authenticity, controllability and easy comparison of the experiments. The proposed design of the experiment can provide reference for further experimental data acquisition.
