中国多熟种植的发展现状与研究进展

多熟种植是中国重要的农作制度之一,对于提高中国耕地综合生产能力和确保国家粮食安全具有重要作用。为了维护国家粮食安全,适应和领会中央文件精神,总结21世纪以来中国多熟种植的发展状况,在介绍中国多熟种植概况的基础上,详细分析了多熟种植的发展现状,体现在复种指数提升,区域模式多样化、投入产出高效化、机械作业科技化等方面,同时还总结了中国多熟种植的研究进展主要包括多熟种植对气候变化的响应、多熟种植的水分效应、多熟种植的高效栽培技术、多熟种植的研究方法等方面。最后,笔者认为,发展多熟种植是中国乃至世界实现农业可持续发展的必要途径,中国多熟种植未来的发展方向应坚持以多熟种植为主体的集约化可持续发展,发展现代化多熟种植,用地与养地相结合,发展绿色循环农业生产,并努力提高复种指数和资源利用率。

Development Situation and Research Progress of Multiple Cropping in China

Multiple cropping is one of important farming system in China, which plays an important role in improving the comprehensive production capacity of cultivated land in China and ensuring national food security. In order to maintain the national food security, to adapt and understand the spirit of the central document,in this paper, on the basis of overview of the multiple cropping, the author introduces development status of multiple cropping in detail, which includes the improvement of sequential cropping index, diversification of regional cropping patterns, high-efficiency of input-output and technological mechanical operations, etc., and summarizes the research progress of multiple cropping, which mainly reflects in response of multi cropping cultivation to climate change, water use efficiency, utilization of research methods and high-efficient cultivation technique, etc. In short, the development of multiple cropping is the necessary way to realize the sustainable development of agriculture in China and even the world.
