| Abstract: | Based on the meteorological data from the 27 typical meteorological stations in Guangdong and Hainan provinces statistical analysis on the safe period of the fertility change and tassel blossom was made. According to the analysis. The safe period of seed production of the two line hybrid in Guangdong and Hainan provinces at 3 guarantee rates, 100%, 98% and 95% was furthe analyzed. The map of regional planning for seed production in Guangdong and Hainan has been made, and the climate basis and some noticeable problems for the seed production in Guangdong and Hianan provinces have been put forward. |
