摘　　要：冬季地膜覆盖是实现极晚播小麦增产增效的一项关键技术。河津市连续两年对极晚播小麦冬季地膜覆盖技术进行了示范推广,取得了较好种植效益和社会效益。文章对极晚播小麦概念进行了界定,对极晚播小麦冬季地膜覆盖技术的增产机理进行了分析,结合极晚播小麦生育特点,从品种选择、整地播种、覆膜揭膜、施肥浇水等方面,对极晚播小麦冬季地膜覆盖技术进行了系统总结。Mulching with plastic film in winter is a key technology for increasing yield and increasing efficiency of late sowing wheat.In this paper,through the demonstration and promotion of the winter mulching technology of the very late sowing wheat in Hejin for two consecutive years,the time of obtaining better planting and social benefits was analyzed and studied.In this paper,the concept of late sowing wheat was defined,and the mechanism of increasing yield of late sowing wheat covered with plastic film in winter was analyzed.Then,combined with the growth characteristics of late sowing wheat,the technology of late sowing wheat covered with plastic film in winter was systematically summarized from the aspects of variety selection,land preparation and sowing,film mulching and stripping,fertilization and watering.
