香蕉原产热带地区,适宜气温是15.5～35℃,最适宜是24～32℃。当气温降至10～12℃,不仅植株受影响,且果实成长缓慢,出现小果,品质下降。温度再降至5℃,蕉叶便出现冻害现象。继续降至2.5℃,蕉叶就严重受害。如有持续一夜0℃低温,整个蕉园可完全受损。我省南部海拔800米以上的地区及北部金沙江沿岸产蕉区,如巧家县冬季常有这样的低温,给香蕉生产的发展带来
Banana origin tropical areas, suitable temperature is 15.5 ~ 35 ℃, the most suitable is 24 ~ 32 ℃. When the temperature dropped to 10 ~ 12 ℃, not only the affected plants, and fruit growth is slow, small fruit appears, the quality declines. Then the temperature dropped to 5 ℃, banana leaves appear frostbite phenomenon. Continue to drop to 2.5 ℃, banana leaves will be seriously injured. If the overnight 0 ℃ low temperature, the banana can be completely damaged. In the southern part of our province, the area above 800 meters above sea level and the banana area along the Jinsha River in the north, such as Qiaojia County, often have such low temperatures in winter, bringing about the development of banana production
