Based on fertility conversion index of sterile female parent AP64S, whose sterile character was induce by sensitivity to light and temperature, and the data of day-to-day temperature and theoretical daytime from 1951 to 1992 in twelve regions in one rice cropping zone in the South of China, a climatic method to determine sowing time interval in seed production of two-line hybrid rice Liangyou Peijiu (AP64S/9311) was developed. In terms of production characteristics of two-line hybrid rice, the seasonal changes of the steady and optimal sterile periods of AP64S in the different regions were firstly confirmed. The seasonal changes of the sowing time interval of parents in the seed production were then calculated by using model of rice growth and development period. This study provided a method to determine the regions and the sowing time intervals in seed production of two-line hybrid rice. 以两系杂交稻两优培九(培矮64S/9311)为研究对象,以光温敏不育系培矮64S(母本)的育性转换指标集和南方一季稻区域12个地区1951～1992年的逐日温度和理论日长资料为基本分析依据,提出了一种制种播差期决策的气候学分析方法。该方法根据两系法杂交水稻的生产特点,首先确定培矮64S在不同地区的稳定不育期和最佳不育期的季节和规律,然后用水稻生育期模型计算制种亲本在不同季节的播差期及其变化规律。本研究可以为宏观决策两系法杂交稻的制种区域和播差期提供方法和依据。    相关查询 sowing time sowing time density optimum sowing time time of sowing sowing-time different sowing time sowing time tests rice sowing time pea sowing time sunflower sowing time critical sowing time buckwheat sowing time
