本文分析了气象因素与作物对地下水利用量相关性,不同地下水位对小麦生态、生理和产量的影响。并应用土壤水动力学原理分析小麦各生育期根系吸水规律。提出不同土壤类型地下水适宜埋深,为黄淮平原节水灌溉和排水标准提供依据。
This paper analyzes the correlation between meteorological factors and crop utilization of groundwater and the effects of different groundwater levels on the ecological, physiological and yield characteristics of wheat. Soil water dynamics was used to analyze the root water uptake rules of wheat at each growth stage. It is suggested that groundwater of different soil types should be suitable for buried depth and provide basis for water-saving irrigation and drainage standards of Huang-Huai Plain.
