摘要： 为了分析气温变化和分期播种对获嘉县小麦生长发育及产量的影响，利用线性分析方法，依据1960—2010年的气温资料统计显示，平均气温和最高气温在冬春季有明显变暖，夏季反而有降低的趋势，最低气温全年都表现为变暖的趋势。同时，通过2010—2011年冬小麦的分期播种试验，从气象因子对小麦生育发育期的影响分析研究，确定小麦适宜播种期，并找出影响获嘉县小麦关键生育期的主要气象因子温度的适宜指标，同时找出影响小麦后期产量的灌浆期的主要气象因子。日照是影响灌浆速度的主导气象因子，温度是限制因子，其他气象因素的影响一般为间接作用，为在生产中提高小麦产量方面制定相应的科学措施提供依据。

Abstract: The aim was to analyze the temperature changes and different sowing dates on the Huojia County wheat growth and yield of the impact by using linear analysis methods. The 1960-2010 years temperature data from statistics showed that the average temperature and maximum temperature was significant warming in winter and spring, summer, but decreased, the minimum temperature all year round performance for the warming trend. Through the 2010-2011 winter wheat phased seeding experiments, analysis of the impact of meteorological factors on wheat growth and development of identified wheat suitable for sowing, the author identified key growth period for the Huojia County wheat meteorological factors temperature appropriate indicators, to identify the main meteorological factors affecting the production of wheat late grain filling stage. Sunshine was filling rate of the leading meteorological factors, temperature was a limiting factor, and other meteorological factors affected the general indirect effects, and provided the basis for the development of appropriate scientific measures to improve wheat production in the production.
