Abstract: The proper formula of sugarcane special fertilizer, which were adaptable to the sugarcane growing areas in Chongzuo, Tuolu, Fusui, Ningming in Guangxi, includes 29.8% of total nutrient(N,P,K) and the ratio of N, P and K was 8:11.8:10, on the base of the model and parameter for fertilizing on upland in Guangxi. The trial results showed that, by applying 29.8% sugarcane special fertilizer, 30% conventional compound fertilizer and conventional fertilizer (used as the control, CK) respectively to the sugarcane field, the number of millable stalks was 61650, 60150, 61350 per hectare, and the average yield was equivalent to 102435kg/hm2, 91530kg/hm2, 84345kg/hm2. Besides, the average sugar content was 14.49%(absolute value, hereafter)，14.30% and 14.06% respectively. The net agricultural income attained per hectare with the application of 29.8% sugarcane special fertilizer was 1962.9 RMB yuan and 3256.2 RMB yuan respectively more than that with the application of 30% conventional compound fertilizer and conventional fertilizer.
