再生稻的生育期,严格地说,是以潜伏芽解除休眠开始萌动,至再生稻穗成熟的历时天数。通常以再生稻抽穗期为界线,之前为再生稻幼穗分化生长期,之后为再生稻抽穗杨花结实期。但由于再生稻潜伏芽在头季稻生育后期业已萌动发育生长,与母茎稻穗的发育灌浆成熟期重叠进行,营养生长与生殖生长难以截然分开。杂交中稻齐穗后15天倒二节潜伏芽(再生稻)开始幼穗分化,它与头季稻灌浆成熟同
Reproductive rice growth period, strictly speaking, lurking bud dormancy began to germinate, to reproduce the ear maturation of the number of days. Normally, the heading date of ratooning rice is used as the boundary, which is the differentiation and growth stage of ratoon rice and then the heading stage of ratooning rice. However, as the latent bud of ratoon rice has germinated and germinated during the later growing stage of the first season rice, it is difficult to separate the vegetative growth from the reproductive growth. The 15-day hybrid rice midgut down two lurking buds (ratoon) began panicle differentiation, which is consistent with the first season of rice grain filling mature
