通辽市气候资源特征对玉米生长的影响分析

Effects of climate resources on the growth of maize in Tongliao city

以通辽市7个气象监测台站1981—2015年逐日的温度、降水为基础数据,采用统计分析的方法研究通辽市气候特征,并结合玉米的生长特性,分析通辽市的气候特征对玉米生长的影响。结果表明:通辽市的界限温度较适合晚熟玉米的生长,但是降水偏少且年变率大,保证率不足,导致玉米生育期内干旱成为主要的限制因素。

Based on daily temperature and precipitation data of seven meteorological monitoring stations between 1981 and2015 by statistical analysis method of Tongliao city climate characteristics, combined with the growth characteristics of corn,effects of Tongliao city of climatic characteristics on the growth of maize were analyzed. The results showed that the boundary temperature of the Tongliao city was more suitable for the growth of late maturing maize, but less precipitation and the annual change rate was big, resulting in the drought had become the major limiting factor during the maize growing period.
