湖南两系法杂交水稻种子生产时空决策计算机智能选择系统

Study on Climate Decision Support System for Seed Production Site of Two-Line Hybrid Rice

摘要: 制种基地和时段的选择是两系杂交稻制种的成败的关键，本文提出了两系杂交稻制种三个安全期的概念，根据湖南省50年气象资料，在考虑气象要素与经、纬度及海拔高度的基础上，运用地理信息系统的空间分析方法，对湖南省两系杂交稻制种的风险进行了评估，研制出两系杂交稻种子生产的基地气象决策支持系统，依据此系统确定湖南省两系杂交稻制种的适宜区域与时段，为两系杂交稻的高产高效安全制种提供了强有力的技术支撑。

Abstract: To select a suitable site and safe duration is very vital to the success of hybrid rice seed production for two-line hybrid rice seed production. The three safe periods that we should pay attention to are put forward. Using spatial analysis of GIS, the climate risk for seed production is assessed on the basis of Hunan climate data in 50 years and analysis on the relationship between climate factors and the longitude, latitude, height above sea level. The climate decision-making support system for seed production base area of two-line hybrid rice is designed and appropriate region and season for seed production are decided. The system provides the technical support for the site selection of the two line hybrid rice seed production.
