摘要
再生稻能够充分利用温光资源,一种两收,能提高复种指数和单位面积粮食产量,是增加水稻总产的一条重要途径,对保障我国粮食安全意义重大。再生季有效穗数是影响再生稻产量的重要因子,而有效穗数取决于再生芽萌发能力。提高再生稻腋芽萌发能力对提高再生季水稻产量有关键作用。本文介绍了国内再生稻发展现状,综述了腋芽萌发能力和其影响因素以及提高腋芽能力的技术措施等,并提出了未来加强再生稻腋芽萌发的研究重点,以期为再生稻高产栽培提供理论依据。
Ratoon rice can make full use of heat and light resources.It has the advantage of two harvests with one sowing,and it can increase multiple cropping index and grain yield per unit area,which has great importance to rice production and food security in our country.The effective panicle number plays a vital role in the yield formation in ratoon rice,which depends on the germination ability of regeneration buds.Therefore,improving the axillary bud germination ability of ratoon rice holds the key to increasing rice yield in regenerative season.In this paper,we outlined the current research advances in the mechanism of axillary bud germination and the influencing factors of the germination ability as well as the technical measures to improve axillary bud germination ability.We also proposed the research highlights in the future on enhancing axillary bud germination.It will lay a theoretical basis for higher yield in ratoon rice.
