摘要
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。
The mixture planting of different rice varieties is a new planting model in rice production. Based on the advantages of yield increase and better disease resistance of the traditional rice interplanting, the mixed sowing and planting model in a certain ratio among different varieties or the full mixture planting is suitable for large-scale mechanized production and easy to expand commercially without any additional increase in labor force and production cost. The research and application was reviewed on the mixed planting models of different rice varieties. The models of interplanting and full mixture planting were compared in their strength and weakness. The interactive effects were analyzed on the disease resistance and grain yield in the mixed planting of different rice varieties. The key techniques, including variety selection, number of mixed varieties, mixed ratio of different varieties and mixed planting methods, were discussed and the future research emphasis and orientation was suggested, for the rice vari- etal mixture planting.
