再生稻栽培是提高土地利用率的一种方式,我国明代的《农政全书》就有记载。再生稻在调节农忙季节,减轻劳动强度,节省劳力和成本,以及提早冬作的播种期上都有着一定意义。但因品种、栽培方法与气候的影响,产量不稳,以致过去各地种植较少。 Ratooning cultivation is a way to improve land use efficiency, the Ming Dynasty, “the whole book of agriculture,” there are records. Ratooning rice has some significance in adjusting the busy season, reducing the labor intensity, saving labor and cost, and sowing the early winter crop.
