摘要
通过对旱秧抛栽不同秧龄分蘖发生及其产量的比较，结果为：（1）对分蘖的发生。单株分蘖总量以秧龄40d为多，有效分蘖数以秧龄35d为多，无效分蘖数以秧龄50d为多。（2）产量比较。秧龄35d的产量最高，秧龄40d的产量次之。综合上述结论可初步认为，旱秧秧龄在35～40d时是大田抛栽适期。
This article introduces a comparison of the tossed rice seedlings'growth in their different instar from three aspects of tillering, emergence and yield.A preliminary result is that the right tossing time of dry nursery is in the instar of 35-40d.
