摘要
再生稻是一种在不需要犁田栽秧的情况下短时间内再收获一季的高效特殊稻作模式,具有省时、省工、省肥、环保、高效、精简等优点,对提高粮食产量、确保粮食安全、提高稻田综合效益具有重大意义。详述了再生稻的发展进程和研究现状,总结并分析了再生稻品种、收获期留茬高度、水分管理、植物生长调节剂、养分运筹(促芽肥、出苗肥、硒肥)等对再生稻产量和质量的影响。提出了“绿肥+”、“全程机械化+”再生稻的创新综合田间管理稻作模式以改善稻田土壤环境、提高种植农户收入和实现再生稻的绿色现代化生产。展望了再生稻的发展趋势,以期为再生稻的发展和推广应用提供参考和借鉴。
Ratoon rice is a highly efficient special rice cropping mode that can have another harvest in a short period of time without plowing and transplanting.It has a great significance to improving grain production,ensuring food security and increasing the comprehensive benefits of rice fields because of its advantages of saving time,labor and fertilizer,as well as environmental benign,high efficiency and simplification.In this paper,the development process and research status of ratoon rice were discussed in detail,and the effects of ratoon rice varieties,stubble height in harvest period,water management,plant growth regulators,nutrient management(bud-promoting fertilizer,seedling promoting fertilizer and selenium fertilizer)on the yield and quality of ratoon rice were summarized and analyzed.The innovative integrated field management rice farming models of"green manure+","full mechanization+"ratoon rice were put forward to improve the soil environment of paddy fields,increase the income of farmers,and realize the green and modern production of ratoon rice.The development trend of ratoon rice was also prospected in order to provide reference for the development and application of ratoon rice.
