摘  要:
根据时域反射仪(TDR)、E601蒸发皿和质量法测量获得的茄子需水量的结果,探讨了后两种方式测量的精度和误差。以时域反射仪(TDR)的测量数据为参照进行误差分析表明,E601蒸发皿的测量值中误差为0.98,质量法测量值中误差为0.28。建立了质量法测定大棚茄子需水量的计算模型,对大棚茄子需水量计算以及灌溉管理和灌溉系统设计有一定的参考作用。

摘  要:
Based on the experiment results of water requirement of eggplant through three methods,namely Time Domain Reflectometry(TDR) method,E601 pan measuring method and Quality measuring method,the precision and error of the latter two methods was discussed in this paper.Taking the measuring result of Time Domain Reflectometry(TDR) method as standard,the measurement errors of the E601 pan measuring method and Quality measuring method come out at 0.98 and 0.28,respectively.According to the test data analysis,the water requirement model for greenhouse eggplant is built,which has some useful reference for greenhouse eggplant irrigation management and irrigation system design.
