摘　　要：花期预测是保证水稻杂交繁育过程中花期相遇的重要措施,也是花期调节的依据。花期预测方法因亲本类型、亲本特性、气候环境等因素而异,介绍了生产中实用的多种花期预测方法,主要有向导田指示预测法、对应叶龄直接对比预测法、回归方程预测法、根据后三叶预测法、圆秆拔节预测法、幼穗剥查预测法等,每种方法需要一定时间熟悉掌握,以保证预测的准确性。在所有的花期预测方法中,以幼穗剥查预测法最为准确可靠。Florescence prediction is an important measure to ensure the seed production of hybrid rice in the process of flowering ,which is also the basis of the regulation in flowering period. Florescence prediction methods vary with different conditions of parent types, parental characteristics, climatic ,etc..This article introduced some practical methods of florescence prediction, mainly including guide-field prediction ,empirical-formula prediction,leaf age comparison prediction,regression-equation prediction and so on. Each method should be skillfully mastered in acertain time,in order to ensure the accuracy of prediction. Among all these methods, the prediction of young spike stripping is the most accurate and reliable one.
