关中灌区小麦、玉米高产节水灌溉的几个指标确定

Determination of Several Water-saving Irrigation Indicators for Wheat and Corn with High Yield in Guanzhong Irrigated Region

对陕西省洛惠渠灌区、宝鸡峡灌区试验站多年积累的大量试验资料进行了系统整理和分析,确定了作物灌溉湿润层深度,适宜的土壤水分指标,基本的灌溉方式以及灌水定额等这些作为作物灌溉基本依据的具体指标。研究结果对于陕西省关中地区主要种植作物——小麦、玉米在作物稳产高产的前提下实现节水灌溉具有重要的现实和指导意义。

Based on the analysis of long-term experimental data from Luohui and Baojixia irrigation regions in Shaanxi Province,some important irrigated indicators such as the depth of wetted soil,suitable soil moisture and the method of irrigation were determined,which may provide helpful guild for getting the goal of saving water and high crop yield of wheat and corn for Guangzhong irrigation region of Shaanxi Province.
