水稻混合种植的抗逆增产研究进展

Research Progress on Stress Resistance and Yield Increase in Mixed Rice Planting

不同水稻品种混合种植是一种通过提高生物多样性来增加水稻抗性能力和产量及稻米品质的新型绿色栽培模式。综述了水稻混合种植的研究进展和应用情况,包括混合种植两种模式间栽和混栽之间的比较,分析其抗逆增产的作用机制,从品种选择、栽种比例、栽培方式和移栽密度等方面探讨了水稻混合种植的关键技术。总结了水稻混合种植在抗性、产量和稻米品质方面的应用情况,指出目前水稻混合种植的缺陷与不足,并提出了今后需要重点加强的研究方向。

Mixed planting of different rice varieties is a new green cultivation pattern to increases rice resistance,yield and grain quality by improving biodiversity.The research progress and application of mixed rice planting were reviewed,including the comparison between the two modes of mixed planting,namely the inter-planting and the mixed planting.The mechanism of stress resistance and yield increase was analyzed,and the key technologies of mixed rice planting were discussed from the aspects of variety selection,planting proportion,cultivation method and transplanting density.The application of mixed rice planting in resistance,yield and grain quality was summarized,the defects and shortcomings of mixed rice planting at present were pointed out,and the research directions to be strengthened in the future were put forward.
