多年生稻是利用长雄野生稻发达的地下茎培育的水稻品种，配套相应的栽培技术，可以实现水稻种植1次，连续收获5~10年，期间省去了购买种子、育秧、犁田耙田、插秧等生产环节，节本增效，是一种绿色、轻简化、可持续的稻作生产方式。为使该技术本地化，2017年贵州引进了多年生稻及其配套栽培技术。通过3年来对多年生稻品种与稻鱼鸭共育技术的实践，利用多年生稻抗性特点与稻田生态调控互补优势，建立了一套不施农药、少施化肥的“多年生稻+鱼+鸭”轻简高效稻田综合种养技术。

Perennial rice technology consists of perennial rice varieties developed by utilizing the rhizome trait of the wild rice species, Oryza longistaminata, and the related crops management techniques. The technique enables us to plant rice only once but consecutive harvest for 5 to 10 years, during which there is no need for several production processes, such as purchasing seeds, seedling nursery, plowing fields and transplanting. The technique represents an efficient and sustainable rice production strategy, which is characterized by its environment-friendliness, cost saving and increasing effectiveness. In order to localized the technique in Guizhou, perennial rice varieties were introduced since 2017 and which were applied in rice-fish-duck system by 3 years of study, combined complementary advantages of high resistance of perennial rice and ecological regulation in paddy field, established a set of “perennial rice-fish-duck” light and efficient comprehensive cultivation technology without pesticide and less chemical fertilizer.
