前郭县农业气候资源对玉米产量的影响


打开文本图片集

摘要 近56年来,前郭县农业气候资源发生了显著变化,对前郭县的玉米产量产生了显著影响。研究发现,玉米的产量变化与生长季内的降水量、日照时数、积温和平均气温的相关性较好,其中,玉米产量与降水量的正相关性最高,即玉米产量越高,所需要的水分就越多;玉米产量与日照时数的负相关性最高。

Impact of Agricultural Climate Resources on Maize Yield in Qianguo County

Zhang Lei et al(Qianguo Meteorological Bureau, Qianguo, Jilin 138000)

Abstract In the past 56 years, the agricultural climate resources in Qianguo County have changed significantly, which has had a significant impact on the corn yield in Qianguo County. It was found that the change of corn yield was well correlated with precipitation, sunshine hours, accumulated temperature and average temperature in the growing season, among them, the positive correlation between corn yield and precipitation was the highest, that was, the higher the corn yield, the more water was needed; the negative correlation between corn yield and sunshine time.

Key words Meteorological disaster; Rainstorm; Drought

利用前郭縣气象局综合观测业务集成平台提供的月平均资料,对当地玉米产量与温度、降水、日照时数等农业气候资源进行线性趋势、突变、年代际变化特征等相关分析,有助于加深对前郭县近56年来气候变化的了解和认识,提高前郭县农业发展水平,对前郭县的气候预报、预测也具有重要意义。(剩余3763字)
