气候是影响辽宁省新民市玉米年产量出现波动的原因之一。基于此,根据新民市多年农业气候资料,采用直线滑动平均模拟法及相关系数分析法对当地气候因子与玉米气象产量的关系进行分析,得出降水是影响玉米气象产量的主要因子,其次是积温和日照。降水时空分布不均是2013年当地玉米产量下降的主要原因。
Climate is one of the reasons that affect the annual output of corn in Xinmin City of Liaoning Province. Based on this, according to the multi-year agro-climatic data of Xinmin City, the relationship between local climatic factors and maize meteorological output was analyzed by using the method of straight line average moving simulation and correlation coefficient analysis. It was concluded that precipitation was the main factor affecting maize meteorological output, followed by accumulated temperature And sunshine. The uneven temporal and spatial distribution of precipitation is the main reason for the drop in local maize production in 2013.
