中文摘要：

以荷兰＂碧玉＂水果黄瓜为试材,建立叶片扩展与累积生长度日之间的关系模型,研究基于器官发育模型的干物质再分配过程,确定了不同植株叶龄、不同位置的叶片获得干物质量模拟模型,并对所构建的干物质再分配模型进行了验证分析。结果表明：叶龄为41、3和20叶龄器官干物质重模拟值和测量值之间的均方差误差RMSE分别为0.0090、.011和0.107,模型模拟结果与试验观测值具有较好的一致性,模型达到了一定的可靠性和准确性。

英文摘要：

＇Biyu＇fruit cucumber from the Netherlands was used as experimental material in this study.The relation model of leaf expansion and cumulate growing days was established for research of process of dry matter redistribution based on organ development model.Dry mater simulation model of leaves in different ages and positions was achieved,analyzed and validated.The results showed that unbiased variance error RMSE of stimulation value of leaf organ dry matter weight and measured value for the leaf age of 4,13 and 30 was respectively 0.009,0.011 and 0.107.The stimulated results were consistent with the actual measured value.Therefore,we can tell that the model achieved a certain reliability and accuracy.
