Abstract
Taking no nitrogen fertilizer as the control,three treatments with equal amount of 15N-labeled urea were designed to study the effects of application times of nitrogen fertilizer on dry matter accumulation,yield and quality of sugarcane varieties ROC22.The results showed that with the increasing of nitrogen fertilizer application times,dry matter accumulation,stalk yield and sugar yield of sugarcane increased significantly,while sucrose content in sugarcane stalk decreased slightly.The effect of application times of nitrogen fertilizer on dry matter accumulation in organs and at the growth stages of sugarcane was significant.
