盐城市气象因子与水稻产量关系的研究

为了综合分析气象因子与盐城市水稻产量的关系及各个年份的丰歉指标，利用同异分析法对盐城市2001-2009年度水稻全生育期的主要气象因子进行了分析评价。结果显示：2001、2002和2004年为丰产年份，2005、2008和2009年为平产年份，2003、2006和2007年为歉产年份；并与对应年度的水稻平均产量表现对比，其结果非常接近。同时也验证了同异分析法在研究气象因子与水稻产量关系研究中的应用价值。

Study on the Relationships between Meteorological Factors and Rice Yield in Yancheng

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 resu...
