the filed experiment of slight saline water irrigation was carried out, and the influence of slight saline water concentration and rotation irrigation of fresh water and slight saline water on the crop growth and yield was analyzed based on the review of research results of slight saline water irrigation.
在结合国内外微咸水灌溉试验成果的基础之上,利用大田微咸水灌溉试验,分析了微咸水矿化度和咸淡轮灌次序对作物生长和产量的影响,研究结果表明小麦的产量随灌水矿化度的增加而减少,不同轮灌次序的咸淡轮灌试验结果表明,采用咸淡轮灌产量的大小次序为淡淡咸>咸淡咸>淡咸咸。
Based on the analysis of influencing factors for water allocation efficiency,and integrating the actual condition of water allocation system of large-sized irrigation district of the Yellow River diversion, the functional relationship between the regional allocation efficiency and water allocation quantity is established using the number of rotational irrigation groups as the parameter.
在分析影响配水效率的各种因素基础上,结合引黄大型灌区配水系统的实际运行工况,从整体上给出了以轮灌组数为参数的区域配水量与配水效率之间的函数关系,与目前使用的选择典型渠道的常规计算方法对比分析,并用实测资料进行了检验。
