Paper Abstract

According to ratoon rice growth and yield formation with meteorological conditions, the paper analyzed the main climatic factors which influence the growth of ratoon rice, and determined the accumulated temperature and sunshine duration of the key period as the index of climatic regionalization. The fine spatial distribution of ratoon rice regionalization was made based on the spatial distribution of indexes which was made based on the GIS and 1:250,000 DEM. And then the paper reviewed the characteristics of various types of regional climate resources separately and put forward proposals in allusion to the cultivation based on the coordinated development between the ratoon rice and other crops in late autumn, the development of annual planting plan and cultivation methods.
