英文摘要	依据黄淮麦区及其周边地区的36个农业气象观测站20a的观察资料,分析了影响冬小麦拔节期的主要因子;建立了已拔节概率随时间变化的方程,分析其重要参数的地区分布.并讨论了造成地区差异的原因和生产应用上的问题.; Twenty years data of winter wheat elongating time, varieties, vernalization feature,and average air temperature of every 10 days in spring,occurrence and injury of frost,etc. were collected from 36 agro-meteorological observation stations,which are located in Huang-Huai wheat production area and its around areas. With these data, the main factors that affect the elongating time of winter wheat were analyzed; the function on accumulative probability with time was established and the variations of some main parameters in this area were also analyzed. Finally, the causes for the variation in parameters were discussed and the guidance for the practical production was also proposed.
