高纬度半干旱地区年际间气象因子变化及对春玉米产量的影响
Influence of Meteorological Factors Change on Yield of Spring Maize in High Latitude and Semi Arid Region
摘要
Abstract
In order to make a cultivation technique measures of maize in semi‐arid areas ,and choose suitable vari‐eties ,maize yield and meteorological data for six consecutive years were analyzed to explore the effect of the main meteorological factors on the maize yield .The results showed that the growing season temperature changed less in recent six years ,but the active accumulated temperature was affected greatly by frost period . Rainfall was above average level of previous years ’ and each month the rainfall was uneven in temporal and spatial distribution ,which lead to the phenomenon of spring drought and summer flood .The amount of rainfall and its temporal and spatial distribution ,early and late frost in individual year ,and other disastrous weather were the main limiting meteorological factors which caused the annual fluctuation of maize yield .关键词
