In this paper, sugarcane observation data and meteorological data of five agrometeorological experimental stations in Guangxi are used to analyze the growth and development characteristics of ratooning cane, meteorological condition differences in different growing stages and its relationship with sugarcane’s growth and development. The results show that: (1) From 2000 to 2011, the emergence date of ratooning cane delays about 2.5 d·a-1; the duration from emergence to stem elongation shortens about 2.9 d·a-1 and 2.7 d·a-1 for the whole growing period; interannual fluctuation of duration from emergence to stem elongation is bigger than the period from stem elongation to maturity, about 15 d (16%) and 4 d (3%) respectively; the maximum stalk height increases about 5.3 cm·a-1 and single stem fresh weight increases about 64.4 g·a-1. (2) Relative humidity of the whole growth period declines about 0.38% every year; sunshine hours in the emergence to stem elongation stage descends 10 h·a-1. For each stage, the interannual variation of minimum temperature and precipitation is big while that of mean temperature and relative humidity is small. The variation of meteorological factors from emergence to stem elongation is higher than those from stem elongation to maturity and in the whole growing period. (3) Rising temperature shortens the ratooning sugarcane growing period obviously, but there is no significant relationship between the highest temperature, lowest temperature, mean temperature and the largest stem height, fresh weight. Effect of precipitation on ratooning sugarcane is very significant in the emergence to stem elongation stage and the whole growth stage except the stem elongation to maturity stage. The effect prolonged or shortened sunshine hours during each growth stage is not obvious. However, in the emergence to stem elongation stage, the reduction of sunshine hours is more favorable for the growth of ratooning sugarcane because the environment becomes wetter.
