Abstract: Ratoon rice has the advantages of short growth period,high resource utilization, low production input and high economic benefit, which could significantly increase the multiple cropping index and rice yield. Simplified cultivation could reduce the inputs and increase production efficiency significantly. It’s great value to improve rice yield and economic benefit by developing the simplified cultivation of ratoon rice, especially in the areas where the light-temperature resources were not enough to grow double season rice and the“double change single”region. The authors summarized the progress of simplified cultivation technology of ratoon rice, and prospected the future research directions in this paper.

Key words: ratoon rice, simplified cultivation, yield, economic benefit

摘要: 再生稻具有生育期短、资源利用率高、生产成本低、经济效益好等优势,可通过提高复种指数来显著提高水稻产量。轻简化栽培可显著降低生产投入,进而提高生产效益。发展再生稻轻简化种植对于稳定水稻产量和经济效益,尤其对南方光温资源一季有余两季不足及“双改单”稻区水稻增产具有重要意义。本文综述了我国再生稻轻简化种植技术的研究进展,并对今后的研究方向进行了展望。
