本文通过系统的分析论证,认为我省沿江旱三熟制地区丰富的气候资源完全可以满足早稻生长发育的需要。优良旱稻品种IRAT109(粳)和农林12号(糯)不仅高产,而且适应性广,力旱稻生产的发展奠定了物质基础。该地区现行耕作制度有利于发展旱稻生产。在旱三熟中推广种植早稻,具有显著的社会经济效益。发展早稻生产,是沿江早三熟制地区现阶段提高粮食产量、增强稻米自给能力的一条切实可行的技术途径。
Through systematic analysis and demonstration, this paper argues that abundant climatic resources in the three dry regions along the Yangtze River can fully meet the needs of early rice growth and development. The excellent upland rice varieties IRAT109 (Japonica) and Nonglin12 (waxy) not only had high yield but also wide adaptability, laying the material foundation for the development of upland rice production. The current farming system in the area is conducive to the development of upland rice production. Promote the cultivation of early rice in dry and three cooked, with significant social and economic benefits. The development of early rice production is a feasible technological way to increase grain yield and enhance the self-sufficiency of rice at the present stage along the river.
