摘要
花期预测是保证水稻(Oryza sativa L.)杂交繁制过程中花期相遇的重要措施,也是花期调节的依据。因亲本类型、亲本特性、气候环境、栽培条件等的不同,花期预测可以采取多种方法,各种方法有难有易,但在实际生产中具体选用何种方法还需要依据个人熟练程度和具体情况进行判断。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 parents flowing period match in the seed production of hybrid rice, and it is also the basis for the regulation of flowering period. Due to the different parent types, parental characteristics, climatic conditions, cultivation conditions, et al, there are many methods to predict florescence, and these methods have varying difficulty levels, but which method to choose depends on the judgment standard and proficiency of each individual in actual production. Among all the methods of florescence prediction, the most accurate and reliable method was the prediction of the young spike stripping.
