I want to know the theoretical ranges of these parameters, and it seems like the change of photeoperiod2 is not sensitive to phenology and yield, how to explain it ?

There is a link in this article to a document that describes how the sorghum model works in Apsim. https://www.apsim.info/apsim-model/description-of-crop-growth-and-development-framework-in-apsim-crop-models/ The Maize model in classic is based on the same concepts - with some changes in parameters, so it should be a good starting place for you.
