育秧方式和壮秧剂对抛栽晚稻生长及产量的影响
Effects of Seedling Raising Methods and Seedling Strengthen Agent on Plant Growth and Grain Yield of Cast Transplanting Rice in Late Season
摘要
Abstract
In the present study, the rice cultivar 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 (Al), 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 Al as well as A4 were lower in order. The yield of A2 was the highest, A3 and Al 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 results 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.关键词
