摘　　要：对广西柳州2003～2006年甘蔗茎伸长时期(6月上旬至9月下旬)甘蔗茎伸长量与主要气象因子进行回归和通径分析。结果表明:大气湿度、温度与日照时数是影响甘蔗茎伸长的主要气象因子;湿度是影响甘蔗茎伸长最重要的因子,湿度的直接效应以及湿度通过温度和日照时数所产生的间接正效应,提高湿度对株高生长量的影响。Regression and path analysis between height growth and main climate factors during the sugarcane growth period from the first ten days of June to the last ten days of September were conduced in Liuzhou of Guang-xi from 2003 to 2006. The result showed that air humidity, temperature and sunshine duration were main climatic factors to influence sugarcane height growth, and the air humidity was the most significant factor to affect sugarcane height growth, the direct path effect of air humidity and indirect path effect through temperature and sunshine duration can greatly enhance sugarcane height growth.
