Discussion on Flexible Seedling Age in Rice Regional Test

  • Online:2015-09-20 Published:2015-09-20

摘要: 新品种区域试验是水稻新品种从选育到推广不可缺少的环节,区域试验中的栽植措施,如移栽秧龄对区域试验结果会有不同程度的影响。本文综合分析了移栽秧龄长短对水稻的生长发育、产量、品质的影响,提出了在南方稻区实行弹性秧龄移栽的建议。换言之,可在水稻区域试验中取消秧龄限制,改为近6叶龄移栽。

Abstract: Regional trial is the indispensable link of new rice varieties from breeding to promotion. The cultivation measures, such as transplanting seedling age have different degrees of influence on regional results. The influence of seedling age on the growth, yield and quality of rice were analyzed in this paper. The author put forward the suggestion of flexible rice seedling age in the South Regional Trial. In other words, we can substitute leaf age for seedling age in the regional trial.

Key words: rice, regional trial, seedling age, leaf age, transplanting
