长江中下游地区是中国小麦(Triticum aestivum L.)和大麦(Hordeum vulgare L.)的重要产区,利用冬闲田种植小麦和大麦可以提高粮食产能,保障粮食安全。近年来,随着农村劳动力成本的增加,冬闲田面积有大幅增加的趋势。针对该区域冬闲田存在的主要原因,提出了机械条播、少免耕和秸秆还田等利用冬闲田的关键技术,同时也提出了实行土地制度创新、增强农田基本水利建设、提高机械化生产水平及加强配套栽培技术研究等政策和技术建议。
The middle and lower reaches of the Yangtze River is an important producing area for both Chinese wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.). Using winter fallow fields to grow wheat and barley can increase grain production capacity and ensure food security. In recent years, with the increase of rural labor costs, there has been a sharp increase in the area of winter fallow fields. In view of the main reasons for the existence of winter fallow fields in this region, the key technologies of utilizing winter fallow fields, such as mechanical drilling, no-till and straw returning, are put forward. At the same time, some key technologies such as land system innovation, enhancement of basic farmland water conservancy construction, enhancement of mechanization production, Strengthen the matching cultivation technology research and other policies and technical advice.
