摘　　要：农田水势(FWP)是SPAC中土壤水势、作物水势和大气水势的统称,由作物微环境信息估算FWP值被称为农田水势软测量技术。按照FWP软测量的实际要求,提出了一种基于Linux-Qt的农田水势软仪表GUI设计方案,采用C语言开发了二级操作界面调用的作物微环境数据查询以及RBF神经网络软测量模型训练、校正以及农田水势实时估计等软测量核心模块,并利用实验样本数据进行了运行检验。The farmland-water potential（FWP） is a general designation of soil water-potential,crop water-potential and atmosphere water-potential in SPAC,the estimated FWP value by the micro-environment information around living crop is called as FWP soft-sensing technique.According to the actual requirements of FWP soft-sensing,a kind of GUI design scheme for farmland water potential soft-sensing based on Linux-Qt is put forward.Based on C language,some core modules of farmland water potential soft-sensing such as query of crop＇s microenvironment data,training and calibrating RBF ANN soft-sensing model and real-time estimation of various farmland water potential are developed one by one.Moreover,thier running verification has carried on using the experiment sampled data.
