| 摘 要： | 根据已报到的研究材料，综述了中国南方稻区再生稻的研究进展。所有的水稻品种均可获得一定的再生稻产量，常规品种的再生稻产量明显低于杂交水稻的再生稻产量，而三系杂交水稻的再生稻产量又较两系杂交稻的再生稻产量低；留桩高度各地因组合不同和生态条件不同而有一定的差异，一般为10-40cm；各节间腋芽在温度、光照和水分适宜的条件下均能较好的萌发，施用赤霉素和细胞分裂素均能有效促进腋芽的萌发，并能提高再生芽的成活率；再生稻腋芽萌发及成活的最适温度为24．5～27．0℃，相对湿度为81％～85％，‘汕优63’再生稻结实率≥70％的临界低温指标是：连续5日平均气温≥210C；头季稻齐穗期剑叶SPAD值、叶片含氮量和群体单位面积的总颖花量3个因子可以用来预测再生稻高产的促芽肥经济施用量；超级杂交稻也可获得较好的再生稻产量。再生稻的栽培技术还可进一步的研究。

| Abstract: | 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 flee 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 flee of conventional varieties is significantly lower than the hybrid flee, 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 era; sections axillary buds can germinate better under appropriate temperature, light and moisture, and the application of gibberellin and eytokinin 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% - 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 flay leave 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. |
