Abstract
本研究之目的在建立水芋收穫指數之動態模式，並進而探討模式之生長參數估計值在不同種植期下的季節變異性，以解析其對最終收穫指數的影響。模式呈一種連續的三相分段線性函數，不但所有種植期下的水芋收穫指數都能配合模式良好，同時該模式能解釋收穫指數總變異的能力高達95%以上。
The objective of this study was to develop a dynamic model of harvest index (HI) in wetland taro. Based on this model, we investigated the seasonal variation of the estimates of growth parameters under different transplanting months, and examined its effect on final HI. The responses of HI with time under different transplanting months were all fitted well using a continuous three-phase piecewise linear function. This model explained more than 95% of total harvest index variation.
