摘　　要：为了解中国杂交水稻在柬埔寨的生长表现和生产应用价值,2016年在柬埔寨王国菩萨省巴干县试种了13个中国杂交水稻品种,系统观察了其生长发育与产量表现。结果表明,这13个品种在柬埔寨试种地均可正常生长,全生育期86~98 d,主茎总叶片数14~15叶。在充分满足生长期水肥协调供应的情况下,24 cm行距、10 cm株距、单株移栽,最终株高80~105 cm、伸长节间数5个左右、茎蘖成穗率51%~76%、单株成穗数6.9~9.9个,主穗长22~30cm、每穗总粒数161~253粒、每穗实粒数154~238粒,结实率90%左右;不同品种的千粒重在19.7~30.1 g之间,单穗实粒质量2.37~4.59 g,单株产量21.8~37.7 g,小区实收稻谷折合产量6.8~10.5 t/hm2。In order to study the growth performance and production value of Chinese hybrid rice in Cambodia,13 Chinese hybrid rice varieties were planted in Bakan county of Pursat province,Cambodia in 2016.The results showed that 13 Chinese hybrid rice varieties could grow normally in test plots.The whole growth period was 86~98 d and the total leaf number of main stem was 14~15.With the fully and coordinately supply of water and fertilizer during the growth period,the seedling were transplanted with the 24 cm row spacing and 10cm planting spacing,and the final plant height was 80~105 cm,the elongated internode number was about 5,the panicle rate of the stem tillers ranged from 51%to 76%,the panicle number was 6.9~9.9 per plant.The main panicle length was 22~30 cm,the total grain number per panicle was 161~253 and the filled grain number per panicle was 154~238.The seed setting rate was about 90%.The thousand grain weight was 19.7~30.1 g,the panicle weight was 2.37~4.59 g,the yield was 21.8~37.7 g per plant.In the trial field,the yield of rice was 6.8~10.5 t/hm2.
