Abstract：A pot experiment of planting sugarcane YZ00-236,designed to have nine treatments on varying time distribution potassium application under drip fertigation,was carried out to evaluate the effects of these treatments on the growth,yield and quality of sugarcane.The results showe that on the condition of equal total potassium application,there had no influenced significantly on growth speed,cane yield and total leaf dry matter under different treatment.With the distribution ratio of potassium in seeding and tillering stage,elongation stage,mature stage are 22.5%～55%～22.5%、30%～50%～20%、20%～60%～20%、10%～60%～30%,respectively,are the better treatments on increasing of the cane sucrose content,juice sucrose content and juice brix.Therefore,it is necessary for the water and nutrient management of sugarcane by drip fertigation and time distribution potassium application.
