摘要
提出了滴灌条件下马铃薯土壤湿润范围调控的一般方法,重点探讨了通过制定更加合理的马铃薯滴灌灌溉计划来调控土壤水分时所要注意的问题。综述了马铃薯的需水特点,马铃薯耗水预报的方法,滴灌土壤水分状况的监控评价方法,降雨对土壤水分调控的影响以及5种制定马铃薯灌溉计划的参考方法。最后,根据国内外研究现状,提出了所需研究和解决的4个相关问题。
This paper presents the general methods for the regulation of soil wetting pattern and discusses some necessary considerations on how to regulate soil water by a more reasonable drip irrigatio n scheduling. Moreover, it summarizes the characteristics of potato water requir ement, and discusses the methods to estimate potato evapotranspiration, the mea ns to measure and evaluate the soil moisture status, the effects of rainfall pat tern on the soil water regulation, and five ways to schedule drip irrigati on for potato. Finally, based on the current research situation, the paper presents four relevant academic problems that need further study.
