摘要
根据广东省台山市都斛镇水稻田控制排灌田间工程试验区的实测资料 ,探讨了在已定工作水头和输水管管径的条件下 ,不同出水口开启状况下各给水栓出流量的数学分析方法 ,同时模拟计算了不同管径 (或改变水头 )条件下给水栓系统运行状态的变化 。
A field experiment was carried out for combining control of irrigation and drainage in paddy rice in Taishan city, Guangdong province. Based on experiment data, a mathematical model is developed to describe flow rate changes for various water dischargers under given work pressure and pipeline diameter and different water discharger's open situation. The operation parameters of the different water dischargers under different pipeline diameters and under different work pressure also are calculated and simulated. The simulated values coincide well with the practically measured values.
