Analysis of grain production situation and influencing factors in Fujian Province

The changing tendency of grain yield in Fujian in 1990-2005 is analyzed,and through building up the generalized production function model and grey correlativity analysis,the significant affecting factors which influence the grain yield of Fujian are found by two time sections.The results showed that grain planting area and pesticide application are the important restricting factors from 1990 to 1997;the grain planting area is the most important factor affecting the grain yield from 1998 to 2005.
