| 摘 要： | 利用线性分析方法,对濮阳市历年玉米产量做了加权滑动平均处理,从中分离出趋势产量和气象产量,并用指标分析法和相关分析法,分析了玉米生育期的气象条件.结果表明,濮阳市玉米产量呈逐年上升趋势,目前已进入高产阶段;当地温度、日照条件优越,有利玉米高产;降水量时空分布不均,时有干旱、雨涝灾害发生,是玉米稳定增产的制约因素.采取相应措施,积极应对干旱、雨涝灾害,是实现玉米稳定增产的保障.

| Abstract: | Using linear analysis method,weighted moving average was conducted to annual corn yield in Puyang City,the trend yield and meteorological yield were separated ; adopting index analysis method and relevant analysis method,the meteorological conditions of corn growth period were analyzed.The results indicated that the local maize yield is increased each year,currently entering into producing stage; the local temperature,sunshine conditions are favorable for corn yield; precipitation spatio-temporal distribution is uneven,with drought,rain water disaster,which is an constrain for maize yield increasing stability.Taking appropriate measures to actively cope with drought,rain droughts,is the safeguard to achieve stable yield of maize. |
