摘要
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 deals with the correlation between meteorologic factors and the the uptake for winter wheat from shallow laying groundwater, as well as the influnce of depth of groundwater level on yield, ecology and physiology of the crop. The regime of uptake process by root system in growing season was analysied by means of soil water dynamic model. The suitable depth of groundwater level was presented for different kinds of soil, which can serve as the reference and standard for water-saving irrigation and drainage in the Huang-Huai-Hai Plain.
