2002 - 2005 Doctoral thesis
Title of the thesis: Calibration, Validation and Application of Cotton Simulation Model COTTON2K.
Pruning and topping are two popular practices in Chinese cotton cultivation. However, these practices were not included in COTTON2K model. We modified the model source code and added the pruning and topping function into the model based on the field experiments with pruning and topping treatment and the control (without trimming and topping). The modified version of COTTON2K was then validated by a series of experimental data and it is sensitive to plant density, nitrogen level, water level and different variety. The model was applied in the two largest cotton planting region: North China region and Xinjiang Region. Cotton production potentiality and water use characteristic in these regions were compared and analyzed.
