濮阳市2012年冬小麦全生育期气象条件对生长发育的影响分析

Analysis on the Impact of Meteorological Conditions of Winter Wheat Whole Growth Period on the Growth and Development in Puyang in 2012

[目的]分析2012年濮阳市冬小麦全生育期气象条件对生长发育的影响。[方法]通过系统分析和实地调查,分析了2012年度濮阳市冬小麦各生育期的气象条件,总体上概括了小麦发育期内的有利、不利气象条件,探讨其对冬小麦生长发育的影响。[结果]2011年10～11月份气温偏高,越冬期推迟,冬前分蘖多,小麦苗情发育较充分;越冬后,小麦苗情转化升级较快,对小麦高产、稳产有一定贡献。2012年小麦播种—成熟前期,日照偏少,降水分布不均,气温波动较大。[结论]2012年濮阳冬小麦全生育期气象因素对全市冬小麦各发育期的生长需求和产量贡献有利有弊,从总体气象因素来看利大于弊。

[ Objective ] The research aimed to analyze the impact of winter wheat meteorological conditions of whole growth period on the growth and development in Puyang in 2012. [ Method] Through the system analysis and field investigation ,the meteorological conditions of the winter wheat growth period in Puyang City in 2012 were analyzed,the advantageous and disadvantageous meteorological condition of in the wheat development period were summarized in the overall, and its impact on the growth and development of winter wheat were discussed. [ Re- sult ] The air temperature are high, overwintering period delayed, before winter more tillers, the wheat seedling growth is full from October to November in 2011. After winter, the wheat status of seedling growth transformation promotes quickly, to the wheat high production and he sta- ble production has certain contribution. The sunshine is less than normal, distribution of precipitation is uneven, the temperature fluctuation is bigger in wheat planting-mature early in 2012. [ Conclusion] The contribution of the meteorological factors of the winter wheat whole growth pe- riod on the growth demand and the output of whole city winter wheat are both advantages and disadvantages. The advantages outweigh the dis- advantages from the overall view of the meteorological factors.
