黄骅市2013年度冬小麦全生育期农业气象条件分析

Annual Analysis about Agro-meteorological Conditions of Winter Wheat in Huanghua City in 2013

分析2013年黄骅市冬小麦冬前生长阶段、越冬阶段、返青至拔节期、抽穗至开花期、灌浆期、成熟至收获期等各个发育期阶段的农业气象条件对其生育进程和产量结构的影响。结果表明:2013年度冬小麦全生育期利多弊少,尽管在返青期出现极端雨雪、低温以及灌浆后期气温偏低、日照偏少等不利天气情况,使发育期推迟,但其它生育阶段的日照、气温、降水等农业气象条件都对冬小麦生长发育较为有利,使冬小麦仍然获得了丰收。

This thesis focus on the effect of agro-meteorological conditions to the reproductive processes and yield structure of winter wheat in various growth stages in 2013,such as,before winter stage,overwinter-ing stage,reviving to jointing stage,heading to flowering stage,filling stage,maturity and harvest stage. the results showed that：In 2013,the advantages of agro-meteorological conditions outweigh the disadvantages. Because,extreme rain、snow、cold happened in the reviving stage ,and low temperatures,less sunshine and other adverse weather conditions fallowed in the late filling stage,the growth of winter wheat was somewhat delayed. However,sunshine、temperature、precipitation and other agro-meteorological conditions were more fa-vorable for the growth of winter wheat in other fertility stage. As a result,the winter wheat still got a har-vest.
