摘要:
通过分析北方地区玉米生产典型区1992—2012年40个有长时间序列记录站点的物候信息与年均温度及≥10℃有效积温之间的关系发现：随着年际之间气温波动，玉米自身进行着生育期的调整，年均温每升高1℃，玉米生育期大致缩短3～5 d；年均温11℃可能是春夏玉米的分界阈值，也可能是一年一作和一年两作两种种植方式的温度划分基线；东北和西北地区作物在1992—2012年间对气候变化响应程度强于华北地区，潜在适应性更强。通过本研究发现玉米物候对气候变化的响应规律，对于阐明玉米品种空间分布与气候变化的关系以及未来气候条件下玉米物候、品种及种植结构变化趋势具有重要意义。
Abstract:
North China is the main producing area of maize. Through analysis of relations between the phenological observations with naturally created climate change at 40 phenological observation sites during the period from 1992 to 2012, it is found that: (1) when the annual average temperature rises by 1℃, maize growing period is shortened by 3～5 days; (2) annual average temperature of 11℃ is proved to be the dividing line between one-crops-per-year and two-crops-per-year planting patterns. During the observation period from 1992 to 2012, crops in northeast and northwest China had greater response to climate change than in North China Plain, indicating that stronger adaptability potentials existed in the cold climate condition.
