再生稻高产高效生产技术研究进展

中国水稻生产面临高产与安全高效、高产与绿色优质之间矛盾和难以协调统一问题，种植方式向规模化、机械化、轻简化和标准化转型。再生稻充分利用温光资源，增产增收、省种省工、减肥减药，有效提高复种指数，发展再生稻对于实现藏粮于地、藏粮于技战略和确保粮食安全意义重大。本文介绍了我国再生稻生产的历史与现状，指出了主要存在强再生力水稻品种选育技术体系不完善、再生稻单产水平不稳定、适宜于机械化栽培的品种少等问题，从生产技术和遗传生理角度综述了再生稻的重点研究方向，主要包括再生稻品种评价体系与品种选育、腋芽萌发机制与产量形成、肥水运筹调控与标准化种植等方面内容，以期为再生稻品种选育、高产栽培和高效生产提供理论依据。

Researched Advances in High-Yielding and High-Efficiency Production Techniques for Ratooning Rice

At present, Rice production in China faces the contradiction between high yield and both safety and high efficiency, high yield and both green and high quality, and it is difficult to coordinate and unify. The planting mode transforms to large-scale, mechanized, simplified, standardizing management practices. Ratooning rice can make full use of heat and temperature resources. It has the advantage of increasing production and income, save seed and labor, reduce fertilizer and pesticide, and it can effectively increase multiple cropping index, which has great importance to rice production and food security, and has great strategic significance for storing grain in land and storing grain in technology.This article reviewed the history and current situations of ratooning rice in China, and printed out the main existing problems, including incomplete of breeding system of strong ratooning ability, unstable of yield ratooning rice, and few varieties suitable for mechanized cultivation. The key research fields of ratooning rice which primarily involved the evaluation system and breeding of ratoon rice varieties, axillary bud germination mechanism and yield formation, fertilizer and water management and standardized planting were summarized from the perspectives of the production techniques and physiological genetics. It will lay a theoretical basis for breeding of strong regeneration varieties, high-yielding cultivation and high-efficiency production in ratooning rice.
