分析了江西6个不同纬度、海拔地点32年以上的日平均气温,认为江西适宜用温敏型两用核不育系制种的地区在赣南及赣中南部,但这些地区繁殖不育系比较困难;温敏型不育系的种子繁殖可在海拔较高的山区进行.提出了在江西气温条件不同的地区分别建立制种基地和繁殖基地的设想,温敏型不育系种子还可在海南岛异地繁殖.
Based on the analysis of the daily mean temperature of six locations in Jiangxi Province at different latitudes and altitudes for more than 32 years, it is considered that the areas suitable for seed production in Jiangxi province are in southern Jiangxi and southern central Jiangxi. However, Which makes it difficult to seed the thermo-sensitive genic male sterile lines in the mountainous areas with higher altitudes.It is put forward that the seed production bases and the breeding bases should be established respectively in different temperature conditions in Jiangxi Province. Hainan Island breeding in different places.
