【摘要】 利用1971—2009年濮阳39年冬季(年前12月—年后2月)积温、1月份平均气温和1月份极端最低气温的历史资料,运用统计学原理和方法进行气候影响统计分析,得出影响濮阳小麦冻害的类型属于入冬剧烈降温型,是小麦入冬冻害最严重的天气类型。提出了小麦冻害防御对策,包括加强管理提高播种质量、加强冬前麦田管理以及冻后补救措施。越冬冻害由于发生时期早,在后期管理上仍有较大的回旋空间,若管理措施得当,小麦仍可获得较高产量。更多还原

【Abstract】 Utilize accumulated temperature,temperature on average and historical materials of the minimum temperature extremely in January in January of winter of 39 years(December-February) of Puyang for 1971-2009 year,Use statistics principle and method go on climate influence statistical analysis,Obtain the type of influencing the wheat freeze injury of Puyang and belong to the violent lowering the temperature type that winter has set in,it is the most serious weather type of freeze injury that winter has set in of the wheat.Propose wheat freeze injury defend countermeasure,including strengthening management raise,sow quality & nbsp;,the remedy after strengthening and managing and freezing in the wheat field before winter.Because the freeze injury of surviving the winter takes place in period early,there is larger circling round in the space in the management on later stage,if control measures are apt,the wheat can still relatively obtain high yield.更多还原
