| 摘 要： | 通过分析时域反射仪(TDR)直接测定的大棚茄子的需水量值以及同步监测的大棚内、外气象数据,建立了大棚茄子需水量计算的地温模型和地温与气温的综合模型。通过精度分析,两种模型拟合值与实测数值的中误差分别为0.145 mm和0.022 mm。研究两种模型各自的优缺点,若两种方法结合使用,相互补充,可提高精度。该成果对大棚茄子的节水灌溉制度研究和灌溉管理有一定的参考作用。 |

| Abstract: | Through analyzing the water requirement value of greenhouse eggplant measured directly by Time Domain Reflectometry(TDR) and the simultaneously monitoring data of the internal and external climate,a comprehensive model including soil and air temperature and a single soil temperature model for water requirement estimation of the greenhouse eggplant are established in this paper.The precision analysis result shows that the mean square errors between the two models and measured data are 0.145 mm and 0.022 mm,r... |
