Research Progress in Rice Quality of Ratoon Rice

doi:10.16819/j.1001-7216.2025.240412

Abstract

Abstract:

Ratoon rice is a green and efficient planting method that is significant for enhancing the profitability of rice cultivation and ensuring food security in China. Due to differences in growth environments and cultivation management practices, there are notable variations in rice quality between the main season and the ratoon season. Typically, the quality of rice in the ratoon season is superior to that of the main season. Factors such as ratooning characteristics, environmental temperature, and water and fertilizer management can influence rice quality by regulating source-sink relationships, the grain filling process, the synthesis of grain nutrients, and the physicochemical characteristics of starch granules. Numerous high-quality and high-yield rice varieties have been identified as suitable for ratoon rice cultivation, considering their ratooning capacity and yields. However, the quality of rice in both the main and ratoon seasons remains a limiting factor for ratoon rice production. This work briefly introduces the rice quality characteristics of the main and ratoon seasons and reviews the factors affecting the quality of ratoon rice and its cultivation regulations in terms of the formation process of rice quality. This review may lay a theoretical basis for the production of high-quality and high-yield ratoon rice.

Key words: ratoon rice, rice quality, ratooning characteristics, temperature, cultivation measures

摘要：

再生稻是一种绿色高效的种植模式，对提高水稻种植效益和保障我国粮食安全具有重要意义，具有广阔发展前景。再生稻头季和再生季生长环境以及栽培管理措施不同，导致头季和再生季稻米品质有显著差异，再生季稻米品质通常优于头季稻米。再生特性、环境温度、水肥管理等都可通过调控源库关系、灌浆过程、籽粒营养物质合成、淀粉粒物理化学特征等影响稻米品质形成。目前虽然已经从再生力和产量角度选育了一批适宜作再生稻种植的优质高产水稻品种，但提高再生稻头季和再生季稻米品质仍然是制约再生稻发展的一个重要因子。本文简要介绍了再生稻头季和再生季稻米品质特征及其差异，结合稻米品质形成的过程及影响因素，分析了影响再生稻稻米品质的因素及栽培调控措施，旨在为再生稻优质高产发展提供理论基础。
