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。 Based on the historical data of accumulated temperature in 39 years in Puyang from 1971 to 2009 (before December and after February), the average temperature in January and the extreme minimum temperature in January, the statistical analysis of climate effects using statistical principles and methods was made The type of wheat frost damage affecting Puyang belongs to the severe temperature drop type in winter, which is the most severe type of weather in which winter wheat frost damage. Proposed wheat frost damage prevention measures, including strengthening management to improve planting quality, strengthening the management of winter wheat fields and post-freeze remedial measures. Winter frost damage as early as the early management of the period there is still a larger room for maneuver, if the management measures properly, wheat can still get higher yields.
