| 摘 要： | 对不同钾肥施用量对甜高粱不同品种产量和含糖量的影响进行了研究,结果表明:相同钾肥施用量处理不同品种对产量和含糖量的影响差异极显著;同一品种采用不同钾肥施用量对产量和含糖量的影响差异极显著;不同品种与不同钾肥施用量互作对产量和含糖量的影响差异不显著,同时,龙甜6号和龙甜2号产量高,含糖量高,在生产上采用的最佳钾肥施用量为7月5日一次性追施硫酸钾75 kg·hm~(-2)。

| Abstract: | Through the study of the effect of different potassium fertilizer application on yield and sugar content of sweet sorghum,the results indicated the following aspects.Firstly,yield and sugar content were significant difference of different varieties.Secondly,yield and sugar content of the same variety were significant difference with different potassium fertilizer application.Thirdly,yield and sugar content were not significant difference under the interaction of different varieties and potassium fertilizer application.Meanwhile,Longtian No.6 and Longtian No.2 had high yield and sugar content.Their best potassium sulphate application was 75 kg·hm~（-2） in one sump sum on July 5 th. |
