通过对各地农业气候相似距的计算 ,得出本区水稻的最适宜引种区为 2 6～ 30°N ,且以耐高温的籼稻为佳 ;小麦最适宜引种区域只有本区周围的一小片区 ,且以半冬性小麦为佳。并对水稻、小麦各主要生育期进行了气候诊断分析 ,将本区划分为 4种熟制适宜推广区域 ,对农业产业结构的调整具有较好的指导作用。 Through the calculation of agro-climatic distances all over the country, it is concluded that the most suitable introduction area for rice is 26 ~ 30 ° N, and the high temperature resistant indica rice is the best. The most suitable introduction area for wheat is only a small area around the area , And semi-winter wheat is better. And the main growth period of rice, wheat climate diagnosis analysis, the area is divided into four kinds of cooked appropriate to promote the region, the adjustment of agricultural structure has a good guiding role.
