摘　　要：2004年早稻利用汕优016，设置不同水层深度抛栽、不同秧苗高度抛栽、不同秧苗带蘖数抛栽、不同苗龄抛栽等4个试验，研究塑盘育秧抛后育苗技术，结果表明：塑盘育秧抛栽适宜水层1-5cm，抛栽最佳苗高15-18cm，秧苗带蘖越多，立苗速度越快，苗龄越小，立苗时间越短。In order to explore the technology of rice seedlings growth in plates and cultivation by throwing, the experiment that the Shanyou 016 as examination rice variety was carried out in 2004. The plant depth, age and branch number of rice seedling were considered in the experiment. Results showed that it was beneficial to standing and establishing of seedling in plant depth 1-1.5cm and 12-15cm for seedling height. The more the branch number is, the faster the standing is. Moreover, the younger the seedings are, the shorter the process of seedling standing is.
