柑桔冻害是当前世界柑桔生产中存在的一个主要问题,据报导,美国不少年份柑桔产量显著下降,主要由于冻害造成的。国外主产柑桔的国家,如日本、苏联、美国除每年发生局部的或不同程度的冻害外,每隔10年左右发生一次严重的大冻害,使大面积的柑桔减产或冻死。贵阳地区是柑桔发展的新区,外来的优良品种温州蜜柑是否能在此地安家落户,取决于能否找出解决冻害的可行办法。 一、贵阳地区的自然特点及温州密柑冻害情况 贵阳地区位于贵州中部的丘陵地带,市区为丘陵盆地,四周丘陵环绕。拔海在1071

First, the natural characteristics of Guiyang and Wenzhou citrus frost injury Guiyang region is located in the hilly areas in central Guizhou, urban areas for the hilly basin, surrounded by hills.
