双季稻区稳定粮食生产的关键在于早稻,但早稻生产长期呈现"低质低效""增产不增收"的典型特征,导致农户种植积极性下降,"双改单"甚至"稻改经"现象突出."十三五"以来,江西创新和大力示范推行"晚稻品种连种"模式,取得了明显成效,促进了双季稻区早稻高质高效发展.但推行中也存在适用品种缺乏、龙头企业带动不强、产业链条延伸不足、缺乏完善的配套设施服务支撑、市场接受程度有待提高等困难与问题.为此,提出加快"晚稻早种"适用品种选育、加强技术集成示范推广,深化农业产业链建设、加强龙头企业带动作用,完善农机社会化服务体系建设,发挥"有为政府"与"有效市场"协同作用、提高"晚稻品种连种"模式的市场接受度等对策建议.
The Connotation Definition,Generation Logic and Realization Path of"Planting the Same Late Rice Varieties in Early and Late Rice Season"Model in Double-Season Rice Areas:A Case Study of Jiangxi Province
The key to stable grain production in double cropping rice areas lies in early rice.However,early rice production has long exhibited typical characteristics of"low quality and low efficiency"and"increasing yield without increasing income",leading to a decrease in planting enthusiasm of farmers for planting,and the phenomenon of"double cropping rice to single cropping rice"or even"rice to cash crop"is prominent.Since the 13th Five Year Plan,Jiangxi has innovated and vigorously demonstrated the implementation of the"planting the same late rice varieties in early and late rice season"model,achieving significant results and promoting the high-quality and efficient development of early rice in double cropping rice areas.However,there were also difficulties and problems in the implementation,such as the lack of suitable varieties,the weak driving force from leading enterprises,the insufficient extension of the industrial chain,the lack of perfect supporting facilities and service support,and the degree of market acceptance to be improved.We therefore proposed the following countermesures and suggestions:accelerate the selection and breeding of suitable varieties for"late rice planted as early rice"and strengthen the demonstration and promotion of technology integration,deepen the construction of the agricultural industry chain and strengthen the driving role of leading enterprises,improve the construction of socialized service system for agricultural machinery,play the synergistic role of"competent government"and"effective market"to improve the market acceptance of the"planting the same late rice varieties in early and late rice season".
