本文结合兴安盟实际情况,对温度、降水和日照适宜度函数的参数及权重进行修订,利用突泉县农业观测站1982~2015年逐日气象资料及同期的玉米单产和生育期观测资料,建立了以日为尺度的兴安盟玉米气候适宜度模型。使用该模型对历年突泉县玉米从播种至成熟期间的逐日气候适宜度进行了计算,同时计算出各生育期的综合气候适宜度以及全生育期综合气候适宜度,并将全生育期综合气候适宜度与历年气象产量进行了相关分析,得出二者显著正相关,且在0.01置信水平上等级相关,表明该模型能够较好的反映出兴安盟气象条件对玉米生长状况的影响,可以用来评价兴安盟玉米生长的气候适宜度情况。
According to the actual conditions of Xing’an League, the parameters and weights of temperature, precipitation and sunshine suitability function are revised. Based on the daily meteorological data of 1982 ~ 2015 and the observational data of corn yield and growth period in the same period, Climate suitability model of corn in Xing’an League with daily scale. The model was used to calculate the daily climatic suitability of maize from the period of sowing to maturity in the past year and calculating the comprehensive climatic suitability of each growth period and the comprehensive climatic suitability during the whole growth period. The correlation between suitability and meteorological yield over the years has been analyzed and it is found that there is a significant positive correlation between the two and the confidence level of 0.01.It shows that the model can better reflect the influence of the weather conditions of Xing’an League on the growth of corn and can be used To evaluate Xing’an League corn growth climate suitability situation.
