WOFOST模型对于云南烤烟的适用性研究

The applicability of WOFOST model for tobacco development in Yunnan province

为研究WOFOST模型对于云南烤烟的适用性,使用2010—2011年在云南烟区玉溪、昭通的烤烟田间实验数据,应用WOFOST模型对云南烤烟潜在生长进行了模拟和验证.用昭通2010年的实验数据作参数校正,得到云南本地化的参数,再用其余实验数据验证.结果显示:WOFOST模型可以较好模拟云南烤烟的潜在生长过程,目前烤烟的产量水平仅相当于其生产潜力的88%左右,仍有提升的空间.

The tobacco field experiment data of Yuxi and Zhaotong during 2010-2011 were used tosimulate the potential growth processes of tobacco in Yunnan province,thus calibrate and validate the WOFOST model for tobacco development. The tobacco field experiment data of Zhaotong in 2010 were applied to the WOFOST model to get the localized WOFOST model parameters for Yunnan province,which were then validated by the rest of the experimental data. The results show that the WOFOST model can simulate the tobacco potential growth process,and the current tobacco yield is only about 88% of its potential yield,thus there＇s still room for increasing tobacco yield in Yunnan province.
