本研究运用时段概率法分析了赣州地区１７个县（市）１９５９～１９９３年连续３５年的气温资料，分别找出了各县（市）日平均气温稳定通过（１００％，９０％，８０％保证率）＞２３．５℃的连续１５ｄ以上有利时段；提出了赣南不同生态点，可分别采用不同季节制种，以及稳定通过育性转换敏感期的最佳时段；根据最佳育性转换期确定安全抽穗和播种期。从结果表明赣南各地均能满足籼型两用核不育系制种的温度值及时段。目前选育出的Ｆ１３１Ｓ等新的籼型两用核不育系，在赣南都有实用价值。
In this study, the time-probability method was used to analyze the temperature data of 17 counties (cities) in Ganzhou for 35 consecutive years from 1959 to 1993. The daily average temperature of all counties (cities) was found to be stable (100%, 90%, 80% > 23.5 ℃ for more than 15 days. The optimal time period for different seasons in South Jiangxi Province and the sensitive period of fertility transformation was proposed. According to the optimal fertility transition Establish safe heading and sowing dates. The results show that all the places in southern Jiangxi can meet the temperature and time period for seed production of the indica dual-purpose nuclear sterile line. At present, new indica breeders such as F131S, which have been bred, have practical value in Gannan.
