In this article, achievements about rationing rice are summarized. All rice varieties can be certain ratoon rice production, ratoon rice the head quarter rice harvest rice pile on the dormant buds continue germination and growth spike rice harvest season. It has many advantages, such as a short growing period, high output, saving seeds, saving labor, low production cost and high efficiency. The production of ratoon rice of conventional varieties is significantly lower than the hybrid rice, and three-line hybrid rice ratoon rice, compared with two-line hybrid rice, has a lower production; the height of stubble around the different combinations and different ecological conditions has some differences, but generally 10-40 cm; sections axillary buds can germinate better under appropriate temperature, light and moisture, and the application of gibberellin and cytokinin can effectively promote axillary bud germination, and improve the survival rate of the regeneration bud; the most appropriate temperature of ratoon axillary buds germinating and surviving is 24.5-27.0℃, and relative humidity is 81% to 85%, ‘Shanyou 63’ of ratoon rice’s seed rate over 70% of the critical low temperature indicators: the average temperature of five consecutive days is ≥ 21℃. First Season Rice full heading Jianye SPAD, leaf nitrogen content and population per unit area of the total number of spikelets three factors can be used to predict the ratoon rice yield promote fertilizer of bud development economic application rate; super hybrid rice can also get better ratoon yield. The ratoon rice cultivation techniques can be further research.
