摘　　要：以杂交水稻"桂两优2号"为试材,设土床旱育秧(A1)、编织布旱育秧(A2)、塑盘旱育秧(A3)、塑盘湿润育秧(A4)4种方式,在不同育秧方式基础上设置施用壮秧剂和不施壮秧剂2个处理水平,研究育秧方式对抛栽晚稻生长及产量的影响。结果表明:抛栽后立苗最快的是A2,其次是A3,A1和A4最慢;分蘖最快、数量最多的是A2,其次是A3和A1,A4分蘖最慢、数量最少;干物质积累A2和A3具有明显优势,其次是A1,A4积累最少;A2的产量最高,产量性状较好,其次是A3,A4产量最低、产量性状较差。施用壮秧剂可促进晚稻生长,改善产量性状,提高产量。育秧方式与壮秧剂交互作用对晚稻产量及主要性状有显著影响。综合晚稻生长和产量及性状看,本试验条件下最适合的育秧方式是编织布与施壮秧剂组合旱育秧。In the present study, the rice cuhivar Gui-Liangyou-2 was used to investigate the effects of seedling raising methods on rice plant growth and yield in the late season of 2011, which including seedlings raised on dry bed （A1）, seedlings raised on woven cloth with dry bed （A2）, seedlings raised on plastic trays with dry bed （A3） and seedlings raised on plastic trays with moisture bed （A4）, all of which were treated by applying and not applying seedling strengthen agent. Results showed that the plant growth of A2 came in the first with a more vigorous status, which including a higher speed of seedling standing, a higher speed and number of tillering as well as a higher dry matter weight, while A3 and A1 as well as A4 were lower in order. The yield of A2 was the highest, A3 and A1 as well as A4 were lower in order. Meanwhile, application seedling strengthen agent promoted the growth and enchanted the yield components and grain yield of rice, The resuhs also indicated that there was interaction significantly between seedling raising methods and application seedling strengthen agent on the yield components and grain yield of rice. Based on plant growth and yield character, the most suitable seedling raising methods was A2 with application seedling strengthen agen in the present study.
