Research Progress on the Influencing Factors of Regenerated Bud Germination and Growth in Ratoon Rice
摘要
Abstract
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.关键词
