摘要
本文利用Richards生长函数和植物干物质分配的汇强理论建立了黄瓜植株地上部单个器官生长和干物质分配模型,该模型采用了一种全局分配方案,把植株上所有器官置于同一条件下进行考虑,更加适用于模拟植物拓扑结构变化情况下的器官生长。模型在计算各个器官汇强时,对同类型但不同生长年龄器官的汇强用其潜在生长速率来表示,有着更为直接的生物学意义。并能够通过试验数据直接获取相关参数。文中用该模型模拟了坐果之前黄瓜植株干物质的分配情况。
The growth and dry matter distribution models of cucumber organs on plant stands that applying Richards growth function and sinks regulation were proposed in this paper. A global partition scheme was adopted for the dry matter allocation among organs by considering all the individual organs at the same level. It was more suitable for the case that plant topological structure of different kind of organs dynamically changed often. And it wae more directly biologic meaning that the sink strength of the same type but differently grown age oranges were caculated by their potential growth rates. And the parameteres of the models were confirmed throught the fitting data of experiments. In this paper the dry matter distribution before cucumber plant fruiting were simuated by the models.
