Abstract

This review was undertaken to summarize the development, experience, and challenges of ratoon rice cultivation over 50 years in Jiangxi Province, China. As the growing labor shortage in the last decade, rice ratooning technology with the main crop harvested mechanically has widely spread and quickly replaced the traditional ratoon rice under manual harvesting. However, rolling damage caused by harvesting machines becomes a critical factor for yield loss in the ratoon season. Some key agronomic practices including variety selection, optimal planting time, nutrient and water management, etc. were discussed here for minimizing rolling damage and achieving high grain yield in the ratoon crop under mechanical harvesting. Besides, some innovative crop rotation systems have been attempted by integrating ratoon rice with duck farming or fragrant taro for reducing weeds and disease incidences and improving farmers' profit. At last, this review analyzed the challenges and opportunities for further expansion of ratoon rice production in Jiangxi from the perspective of cultivation technology, rice market, and government policy.

江西省水稻再生产技术的进展与挑战

本综述旨在总结中国江西省再生稻种植50多年来的发展、经验和挑战。近十年来，随着劳动力短缺的加剧，以机械收割为主的水稻再生技术得到了广泛应用，并迅速取代了传统的人工收割再生稻。然而，收割机造成的滚动损伤成为再生季节产量损失的关键因素。本文讨论了在机械收割条件下，再生稻的品种选择、最佳种植时间、营养和水分管理等关键农艺措施，以最大限度地减少滚动损伤，实现高产。此外，还尝试了一些创新的轮作制度，将再生稻与养鸭或香芋相结合，以减少杂草和疾病的发生，提高农民的利润。最后，从栽培技术、水稻市场和政府政策等方面分析了江西再生稻进一步扩大生产面临的挑战和机遇。
