氣候變化對(duì)年代際東北玉米冷害影響分析
[Abstract]:[objective] Climate change has a significant impact on the northeast region of China's main grain production areas, and it is of great importance and significance to strengthen the analysis of crop chilling damage in Northeast China under the background of climate change to ensure the safety of grain production. [methods] based on the data set of 0.5 擄脳 0.5 擄surface temperature in China from 1981 to 2010, the monthly mean temperature of maize growing season (May to September) in Northeast China was calculated. The sum of monthly mean temperature and the sum anomaly of monthly mean temperature in recent 30 years (1981 ~ 2010) were analyzed, and the trend of climate change in Northeast China was analyzed. According to the Industrial Standard (QX/T 167-2012), Furthermore, the temporal and spatial changes of chilling damage of Northeast maize in different grades of 1980s~2010s were analyzed and regionalized, and the records of historical chilling injury in Northeast China were compared and analyzed. [results] in the growing season of Northeast Maize, the climate tended to warm obviously, the heat increased, and in the last 30 years, the number of years of different grades of chilling injury occurred in Northeast Maize. The region and frequency showed a marked decreasing trend. In the 1980s, cold damage occurred almost every year in Northeast China. In the 1990s, it was the turning point of chilling injury. The number of years of chilling injury in the latter part of the year (1996-2000) was obviously lower than that in the previous period (1991-1995). By October of 21st century, the number of years of chilling injury was further reduced. The area of mild chilling injury was mainly distributed in the middle and southeast regions of Heilongjiang Province, and the frequency of chilling injury was also small (0.1% 0.2 times per year), and the moderate and severe chilling injury occurred only locally. The significant reduction of chilling injury creates very favorable conditions for the continuous high yield and income increase of maize in Northeast China. [conclusion] under the background of climate warming, the chilling damage of Northeast maize was reduced, but severe chilling injury occurred in some years (e.g. 2002,2003,2009), and the occurrence of chilling injury was still uncertain.
