摘要
再生稻是一种在水稻头季收获后,采取特定的栽培措施使头季水稻休眠芽再次分蘖成穗结实,实现二次收获的种植模式。这种种植模式能够充分且高效地利用温光资源,有效提高复种指数,增加单位面积的粮食产量,是我国提升稻田种植效益的重要途径之一。在产量构成因子中,有效穗数对再生季产量及其稳定性有着重要影响。而再生季有效穗数主要取决于再生芽的存活数量以及成苗数量。由此可见,提高再生芽的存活率和成苗率是提升再生季产量的关键。本文详细阐述了再生稻再生芽的生长特性及其生理基础,全面综述了影响再生芽生长发育的各种因素,深入探讨了提高再生芽萌发成穗的可能途径,并对未来的研究方向进行了展望,旨在为再生稻高产栽培提供具有价值的理论参考。
Ratoon rice is a planting pattern that involves taking specific cultivation measures after the harvest of the first-season rice to enable dormant buds to tiller,form panicles,and set grains again,thus achieving a second harvest.This planting pattern can make full and efficient use of temperature and light resources,effectively increase the multiple cropping index,and raise the grain yield per unit area.It is one of the important ways to improve the planting efficiency of paddy fields in China.Among the yield-contributing factors,the number of effective panicles has a significant impact on the yield and its stability in the ratoon season.The number of effective panicles in the ratoon season mainly depends on the survival number of ratoon buds and the number of established seedlings.Therefore,improving the survival rate and seedling establishment rate of ratoon buds is the key to increasing the yield in the ratoon season.This paper elaborated the growth characteristics and physiological basis of ratoon buds in ratoon rice,reviewed various factors affecting the growth and development of regenerated buds,thoroughly explored possible ways to improve the sprouting and panicle-forming rate of regenerated buds,and look forward to future research directions.The aim is to provide valuable theoretical references for high-yield research of ratoon rice.
