| 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)、编织布湿润育秧(A4)、塑盘湿润育秧(A5)5种育秧方式及壮秧剂处理2个因素,研究育秧方式对抛栽早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和A5,A1和A4最慢;分蘖最快、数量最多的是A2,其次是A1,A4分蘖最慢、数量最少;干物质积累A2具有明显优势,其次是A3、A5和A1,A4积累最少;A2的产量最高、产量性状较好,A4产量最低、产量性状较差,其他处理的产量及性状介于A2与A4之间。施用壮秧剂可促进早稻生长,改善产量性状,提高产量。育秧方式与壮秧剂交互作用对早稻产量及主要性状有显著影响。综合早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。 |

| Abstract: | In our study,the rice cultivar Gui-Liangyou-2 was used to investigate the effects of seedling raising methods on rice growth and yield in the early season of 2011,which included seedlings raised on dry bed(A1);on woven cloth with dry bed(A2);on plastic trays with dry bed(A3);on woven cloth with moisture bed(A4) and on plastic trays with moisture bed(A5) at two levels(with or without applying seedling strengthen agent).The results showed that the plant growth of A2 came in the first with a more vigorous status,which included a higher speed of seedling standing,a higher speed and number of tillering as well as a higher dry matter weight,followed by a decreasing oder of A3,A5,A1 and A4.The yield of A2 was the highest,followed by a dereasing trend of A1,A3,A5 and A4.The application of seedling strengthen agent had promoted growth and improved the yield components and grain yield of rice.The results also indicated that there was a significant interaction between seedling raising methods and application seedling strengthen agent on the yield components and grain yield of rice.Based on early rice growth and yield character,the most suitable seedling raising method was A2 with application seedling strengthen agent in our study. |
