Abstract

Abstract:

Using Yongyou 538 and Yongyou 9 as materials, an experiment was conducted to study the effects of three seedling raising methods on quality of long seeding age mechanical transplanting double season late rice. The results showed that compared with water nursery（T1）, the seedling height and biomass of treatment T2 and T3 were inhibited, the seedling rate and basic seedlings were increased, the seedling leakage rate were decreased, and the heading stage of two varieties were delayed after machine transplanting, the yield of Yongyou 538 of treatment T2 and T3 were higher than that of treatment T1, and the yield of Yongyou 9 of treatment T2 and T3 were lower than that of treatment T1.

Key words: seedling raising method, double season late rice, mechanical transplanting, long seeding age

摘要：

以甬优538、甬优9号为供试材料，研究了轻多效唑水育秧（T1）、重多效唑水育秧（T2）和轻多效唑旱育秧（T3）三种育秧方式对水稻超秧龄机插的影响。结果表明，与T1处理相比，T2、T3处理的苗高、生物量受到抑制，成秧率变高，漏秧率降低，基本苗数增加；机插后2个品种的抽穗期均推迟，甬优538 T2、T3处理的产量高于T1处理，甬优9号T2、T3处理的产量低于T1处理。
