【摘要】 对湖南省稻区不同水稻种植模式进行了调研,比较了早晚双季稻、一季稻+再生稻、稻油和稻渔等生产模式的效益,总结了湖南省稻区水稻种植模式调整的问题,并提出了相关建议。结果表明:稻油模式经营风险小,增效稳,是目前比较成熟和稳妥的稻田种植模式,适合在全省大范围推广;一季稻+再生稻模式不利于优质稻产业的发展,增产难以增效,只宜适度发展;稻渔模式快速发展,存在着极大风险,同时可能严重危害耕地和粮食安全。更多还原

【Abstract】 In the study, we have investigated the rice planting patterns in rice-growing areas of Hunan Province, and compared the benefits of four production patterns i.e. double-season rice, single-season rice + regeneration rice, rice+rape and rice+fish. The results show that the rice-rape model has low management risk and stable benefit growth, which is a mature and stable rice field planting mode, suitable for large-scale promotion in the whole province; the single-season rice + regeneration rice model is not conducive to the development of highquality rice industry, and difficult to increase benefits of production, which is suitble for moderate development; driven by the high profits, the rapid development of rice-fish pattern may result in high risk due to great input and unstable market facters, on the other hand, dugging deep ditches adapted to paddy fish-farming even transforming paddy to fishpond may seriously jeopardize farmland and food security.更多还原
