Analysis on Yield Fluctuation of Summer Corn and Influence Factors in Shandong Province
摘要
Abstract
Based on the rule of periodic fluctuation,the corn production status in 1970 ～2007 in Shandong Province was analyzed.The results showed that the corn production in Shandong Province possessed the characteristics as followed.Firstly,the corn production fluctuated with increasing as the background,and also with irregular cycle length and large fluctuation range.Secondly,the fluctuation was largely in line with the classical type.Finally,the expansion period was longer than contraction period.Food policy and natural hazard were the main factors influencing the fluctuation of corn yield.关键词
