Abstract

The study, which was conducted in Klein-Altendorf, Nordrhein-Westfalen in Germany, simulated the effect of temperature and solar radiation on the yield of winter wheat from 1991 to 2004 by using LINTUL 2 model. The parameters of temperature and radiation were modified to check the sensitivity of the model with regard to the two variables. Furthermore, it has been discussed how to maintain the original yield under a condition with variable radiation and temperature by changing species with different temperature sum and light use efficiency. The results showed that: under the same radiation value, the temperature increment was linearly negatively correlated with crop yield. The yield decreased with increasing temperature. Under the same temperature, the correlation between solar radiation and crop yield was positive linear. The yield increased with increasing radiation. The effect of radiation factor on crop yield was more sensitive than the effect of temperature. In worse conditions with increased temperature or decreased radiation, man can keep the original yield by changing the cultivars with different temperature sum and light use efficiency (LUE).
