摘　　要：为了创新中稻再生技术,加快恢复再生稻生产发展,有效提高水稻的综合生产能力,确保山区粮食安全,促进农民持续增收,2005年以来,桂北高寒山区三江侗族自治县的农业科技工作者以实施超级稻示范推广和特色扶贫产业项目为载体,对纯稻作模式“超级稻 + 再生稻”和稻鱼共作模式“优质稻 + 再生稻”栽培配套技术进行试验研究,先后开展了适宜超级稻(优质稻)品种(组合)筛选、不同播期、栽植密度、鱼苗投放量、施N水平及N肥运筹方式、再生稻催(促)芽肥与促苗(蘖)肥用量、生物农药筛选、收割成熟度、留茬高度及稻作模式等对比试验,筛选适合当地推广种植的超级稻 + 再生稻品种(组合),组装集成和探索总结出适合当地纯稻作模式“超级稻 + 再生稻”高产栽培和稻鱼共作模式的再生稻绿色高效配套技术体系,实现了良田、良种、良法与良制相配套。Since 2005, in order to innovate the regeneration technology of mid-season rice, accelerate the resumption of the development of the production of ratooning rice, effectively improve the comprehensive production capacity of rice, ensure food security in mountainous areas, and promote the continuous increase of farmers’ income, agricultural Science and technology workers at the Sanjiang in northern Guangxi are carrying out demonstration extension of super rice and special poverty alleviation industrial projects;the cultivation techniques of super rice + ratooning rice and high quality rice + ratooning rice were studied in this paper;a series of comparative experiments were carried out on the selection of suitable super rice (high quality rice) varieties (combinations), different sowing dates, planting density, amount of fish fry, N application level and n fertilizer operation mode, amount of fertilizer for accelerating bud and promoting seedling (tiller) of ratooning rice, screening of biological pesticides, harvest maturity, stubble height and rice cultivation mode, etc. Screen the super rice + regenerative rice varieties (combinations) suitable for local promotion and planting, assembling, integrating, and explore the green and efficient supporting technology system of regenerative rice suitable for local pure rice cultivation mode of “super rice + regenerative rice” high-yield cultivation and rice-fish cocultivation mode, so as to realize the matching of good fields, good varieties, good methods and good system.
