Abstract:

In order to analysis the relationship between meteorological and rice yield, and ascertain the high-low yield in different years, the main climatic factors during the whole growth stage of rice in 2001-2009 of Yancheng were analyzed and evaluated by identical and different analysis method. The results indicated that: 2001, 2002 and 2004 were high yield years; 2005, 2008 and 2009 were normal yield years; 2003, 2006 and 2007 were low-yield years, and compared with the actual yield of the same year, their results were similar. Meanwhile, it also proved the application value of identical and different analysis method.
