双季晚稻生产数据
收藏资源简介:
双季晚稻是一种生长期较长、成熟期较晚的稻,一般在霜降后(十月中下旬)收割。就是一年中种一季早稻再种一季晚稻。五月中下旬开始插种早稻秧,到七月中下旬时收割早稻;然后紧跟着翻耕水田、插种晚稻秧苗,要赶在农历立秋前插种完毕,到十一月时收割晚稻,赶在降霜前完成收割。单季稻在每年六月中下旬到七月初插秧,十月中下旬开始收割。在中国具有悠久的种植历史,最早见于公元前3世纪的《山海经》的记载。一般认为,古籍中常提到的“两熟稻”和“再熟稻”包括再生稻、混作稻、间作稻和连作稻等,反映了中国稻作制度的多样性。本数据包含全国以及各省(自治区、直辖市)双季晚稻种植面积与产量数据,供关注中国双季晚稻产业市场运行和发展的各方参考。
Double-cropping late rice is a type of rice with a longer growth period and later maturity, generally harvested after Frost's Descent (mid-to-late October). This cropping system involves growing one season of early rice followed by one season of late rice within a single year. Early rice seedlings are transplanted in mid-to-late May, and harvested in mid-to-late July. Immediately afterwards, the paddy fields are plowed and late rice seedlings are transplanted, with the transplantation needing to be completed before the Start of Autumn (lunar calendar). The late rice is harvested in November, before the arrival of frost. Single-cropping rice is transplanted from mid-to-late June to early July, and harvested starting from mid-to-late October. This cropping system has a long cultivation history in China, with the earliest records found in *Classic of Mountains and Seas* dating back to the 3rd century BCE. It is generally believed that the "double-cropping rice" and "multi-harvest rice" frequently mentioned in ancient Chinese classics include ratoon rice, mixed cropping rice, intercropping rice and sequential cropping rice, which reflect the diversity of rice cropping systems in China. This dataset contains data on the planting area and yield of double-cropping late rice at the national, provincial, autonomous regional and municipal directly under the Central Government levels, for reference by all parties concerned about the market operation and development of China's double-cropping late rice industry.
