不同水稻品种混合种植是一种新型的栽培模式。不同品种按一定比例进行的混播混栽或完全混栽模式,在继承传统间栽模式增产抗病等优势的基础上,不增加额外劳动强度和生产成本,且适宜于机械化生产,便于大面积推广。综述了水稻多品种混合种植模式的应用与研究现状,比较了间栽和混栽的特点与不足,分析了混合种植的抗性互作效应及产量互作效应。从品种选择、品种数量、混合比例与种植方式等方面探讨了水稻混合种植的关键技术,并提出了今后的研究重点与方向。 Mixed cultivation of different rice varieties is a new type of cultivation mode. Different varieties of a certain percentage of mixed planting or mixed planting completely mixed mode, inherit the traditional intercropping mode to increase disease resistance and other advantages, based on the increase in labor intensity and production costs, and is suitable for mechanized production, to facilitate large-scale promotion . The application and research status of mixed cropping patterns of rice varieties were summarized. The characteristics and deficiencies of intercropping and mixed planting were compared. The resistant interaction effect and yield interaction effect of mixed planting were analyzed. The key technologies of rice hybrid planting were discussed from the aspects of variety selection, variety quantity, mixing proportion and planting methods, and the future research focuses and directions were put forward.
