探讨桂中蔗区甘蔗钾肥施用效应。为当地甘蔗生产合理施用钾肥提供理论依据。2010-2011年在广西来宾市兴宾区进行了不同钾肥用量对该地区甘蔗生长与产量影响的肥效试验。结果表明，与不施钾肥处理相比，施钾处理的甘蔗节茎长、茎径、产量平均值分别提高了1．29％、6．35％和11．81％。当钾肥施用量达到一定水平（K2O〉275kg／hm^2）时，单茎重随着钾肥继续增加而降低，施氯化钾675kg／hm^2处理甘蔗产量最大，相比不施钾肥处理增产20．09％。可见，在桂中蔗区甘蔗施氧化钾405kg／hm^2，既能确保甘蔗高产，又能保证肥料资源得到高效利用，是一个比较合理的施肥水平。

The effect of potassium fertilization on sugarcane in middle sugarcane area of Guangxi was discussed to provide theoretical basis for reasonable application of potassium fertilizer in sugarcane production. The field experiments were conducted to investigate the effects of different dosages of potassiums fertilizer on growth characteristics and yield of sugarcane in Xingbin District of Laibin City of Guangxi during 2010 to 2011. The results showed that ： compared with no potassium treatment, stem length, stem diameter,yield of sugarcane with potassium treatment averagely increased by 1.29%, 6.35% and 11.81%, respectively. When the application reached a certain level of potash （K2O〉275 kg/hm^2）, the single stem weight continued to decrease as potassium increased. Under potassium application amount was 675 kg/hm^2,the yield of sugarcane reached maximum, compared with the no potassium treatment,increased by 20.09%. Therefore, the potassium application amount of 405 kg/hm^2 was a reasonable level, which ould ensure the yield of sugarcane and the efficiency of fertilizer resources.
