摘　　要：通过对2008—2018年低温干旱对濮阳市晚播小麦生长资料的分析,发现低温干旱对不同耕作管理模式和浇灌方式的麦田所造成的危害不同,生长状况和产量存在明显差异。可见,对晚播小麦耕作、种植、灌溉等的管理方式应根据气象条件、土壤性质、土壤湿度等因素适量、适时地进行,以便充分利用自然资源,趋利避害,稳定提高晚播小麦产量。By analyzing the growth data of late-sowing wheat in Puyang City from 2008 to 2018,it was found that low-temperature drought caused different harms to wheat fields with different tillage management modes and irrigation methods,and there were significant differences in growth status and yields.Therefore,the management methods of late sowing wheat such as cultivation,planting and irrigation should be performed appropriately and timely according to meteorological conditions,soil properties and soil moisture,so as to make full use of natural resources,seek profits and avoid harms,and stably increase the yield of late sowing wheat.
