摘　　要： 通过田间试验,研究甘蔗不同施钾水平对甘蔗产量和品质的影响。结果表明,随着施钾量的增加(1)甘蔗茎径、单茎重有明显下降趋势,有效茎数则有明显上升趋势,甘蔗的茎长、产量无明显趋势。(2)提高了蔗汁蔗糖分、总糖、改正锤度、重力纯度,改善了甘蔗品质。 Effect of applying potassium on yield and quality of sugarcane was studied in field test. The results indicated that the stalk diameter and weight of single stem decreased with the increment of applying potassium, while the number of millablecane （N.M.） increased. The results also showed that applying potassium may increase the juice sucrose content, GRA purity, total sugar content and Brix, but the length of stem and yield has no obvious change.
