【目的】研究中国杂交水稻品种在柬埔寨马德望省的种植长势和产量表现,为中国杂交水稻在柬埔寨马德望省的推广应用提供参考。【方法】2012年旱季(1~4月),将3个中国杂交水稻品种(早优362、特优362和桂源优362)与当地水稻品种(Senpidao)种植于柬埔寨马德望省,测定比较不同品种农艺性状和产量。【结果】不同水稻品种株高间差异显著。中国杂交水稻品种株高均显著高于当地对照品种(Senpidao),但分蘖数较低。中国杂交水稻品种的每穗粒数和穗长也显著高于当地对照品种,其中特优362的每穗粒数最多,桂源优362的穗最长。早优362的千粒重均高于其他3个品种,而特优362和桂源优362的产量显著高于其他两个品种。此外,每穗粒数、穗长和产量间表现出极显著的相关性。【结论】中国杂交水稻适合在柬埔寨种植,旱季在马德望省的Toul Samrong土壤种植可比当地品种增产23%～38%。
【Objective】 The objective of this study was to study the growing status and yield performance of Chinese hybrid rice varieties in Battambang Province, Cambodia, and to provide reference for the popularization and application of Chinese hybrid rice in Battambang Province, Cambodia. 【Method】 Three Chinese hybrid rice varieties (Zaoyou 362, Teyou 362 and Guiyouyou 362) were planted in the dry season (January-April) in 2012 with the local rice variety (Senpidao) in Battambang, Cambodia. Variety agronomic traits and yield. 【Result】 There were significant differences among different rice varieties. The plant height of Chinese hybrid rice varieties was significantly higher than that of the local control (Senpidao), but the number of tillers was lower. The grains per spike and spike length of hybrid rice varieties in China were also significantly higher than those of the local control cultivars. The grain number per spike of Teyou 362 was the highest and that of Guiyouyou 362 was the longest. The grain weight of Zaoyu 362 was higher than that of the other three varieties, while the yield of Teyou 362 and Guiyouyou 362 were significantly higher than the other two varieties. In addition, grain number per spike, spike length and yield showed significant correlations. 【Conclusion】 The hybrid rice in China is suitable for planting in Cambodia. In the dry season, Toul Samrong soil in the Battambang Province can grow 23% -38% more than the local variety.
