气候变化对菏泽冬小麦播种期的影响及对策

 利用36年（1970—2006年）气温资料分析了菏泽市局地气候变化对来年小麦产量的影响。根据相关和综合分析结果，发现局地气候变化对本地区冬小麦的冬前生长具有较大影响。由于传统播种期没有考虑这种影响，其结果严重影响了来年小麦的产量，所以研究冬小麦产量与播种—出苗间平均气温之间关系，并找出适合本地冬小麦适宜播种期，无疑对提高来年小麦产量具有重要意义。

Impact of Climate Change upon Winter Wheat Sowing and Countermeasures

In this paper, the author analyzes the impaction of climate change to the wheat yield in Heze district using the data information collected from 1970 to 2006. Using Correlation analysis and synthesis analysis, the author find out that climate change has great impact on winter wheat growth before winter, and it greatly reduced the wheat yield the next year. It is very important to enhance wheat yield by doing research on the correlation between winter wheat yield and the average temperature during sowing- seedlings emergence time, and find the appropriate winter wheat sowing time in local area.
