Abstract:

Main climatic factors of Xinyang were analyzed and evaluated by identical and different analysis method during rice growth and development in 1996~2005. The results showed that 1997, 1999 and 2001 were high yield years; 1996, 1998, 2002 and 2004 were normal yield years; 2000, 2003 and 2005 were low yield years. A new method was provided on scientific evaluating annual rice yield, the method was feasible, above conclusion was objective and reasonable.
