摘  要:
通过对2007、2008年的实验数据进行分析,建立了以Logistic模型为基础,光合有效辐射积累(GDD)、有效积温(RDD)和作物水分利用累计量(WDD)为自变量,适用于亏缺灌溉条件下温室小型西瓜的干物质积累模型,并将模型模拟值与试验实测值进行相关性分析,结果表明,模型的拟合优度均在0.92以上,所建模型模拟效果良好。

摘  要:
According to the experiment data of 2007 and 2008 year,the dry matter accumulation model suitable for greenhouse Mini-watermelon under insufficient irrigation,which is based on Logistic equation and takes effective accumulated temperature(GDD),effective accumulated photosynthetic active radiation(RDD) and effective accumulated of soil water(WDD) as self-variables,was established in this paper.Moreover,the simulation value was compared with the experimental value.The result showed that the model performed well when compared to the field measured data,and all the fitting coefficients of the model are over 0.92.
