摘要: 利用内蒙古通辽市科尔沁区1980—2009年最高气温、最低气温、平均气温等气象资料和30年产量面积数据,对科尔沁区1980—2009年的玉米不同发育阶段的生长所受的低温冷害影响进行了综合分析,得出玉米发育阶段热量指数、热量指数与玉米产量的关系、冷害指数、热量及冷害变化趋势、热量指数时空分布、冷害频率的时空分布,为玉米发育期的生长阶段提供了科学依据。

Abstract: Based on meteorological data such as the maximum temperature, the minimum temperature and average temperature as well as data of corn yield and area in Horqin District of Tongliao City of Inner Mongolia during 1980-2009, the effects of chilling damage on corm in different developmental stages were comprehensively analyzed from the aspects of heat index, relationship between heat index and yield of maize, chilling damage index, changing trends of heat and chilling damage, temporal and spatial distribution of heat index and chilling damage frequency. The results can provide scientific basis for the growth stage of maize.
