不同生长时期马铃薯产量与气象因子的关系研究

The Research on the Relationship between Potato Yields and Meteorological Factors in Different Periods

将宜昌地区马铃薯产量进行HP趋势分解,得到趋势产量和气象产量,并建立了各个生长时期气象产量与各个气象因子的二次回归方程.结果表明,马铃薯在不同生长时期影响气象产量的气象因子是不同的,同一气象因子在不同生长时期对气象产量的影响程度也是不一样的.

By using Hodrick-Prescott tendency analysis,the potato yields in Yichang city are separated into trend yields and meteorological yields.Then,quadratic regression equations of meteorological yield and each meteorological factor in every growth period are respectively established.The results show that in different growth periods of potatoes the main meteorological factors which affect the meteorological yield are different.And the same meteorological factor has different influencec on the meteorological yield in different growth periods.
