摘要
利用1981—2010年文登区气象资料,分析了文登区气温和降水量变化特征。同时根据文登区冬小麦种植温度适宜度、降水适宜度、光照适宜度和综合适宜度计算结果,对地区冬小麦种植气候适宜性进行了分析。结果表明,从时间上分析来看,文登区冬小麦的气候适宜度呈增加态势,其中,降水适宜度和日照适宜度有所增加,但温度适宜度有所减弱;从冬小麦生育期分析来看,在出苗-分蘖期和分蘖-越冬期气候适宜性最好,在返青-拔节期适宜性最差,这与文登区气候季节变化有关。
Based on the meteorological data of Wendeng district from 1981 to 2010,the characteristics of temperature and precipitation changes in Wendeng district were analyzed.At the same time,according to the calculation results of temperature suitability,precipitation suitability,light suitability and comprehensive suitability in Wendeng,the climate suitability of winter wheat planting in Wendeng district was analyzed.The results showed that from the time analysis,the climatic suitability of winter wheat in Wendeng district was increasing.Among them,the suitability of precipitation and sunshine had increased,but the suitability of temperature had weakened.From the analysis of the growth period of winter wheat,the climate suitability was the best in the emergence-tillering period and the tillering-overwintering period,and the climate suitability was the worst in the green-joining period,which was related to the seasonal changes of climate in Wendeng district.
