施用氯化钾对甘蔗产量和品质影响的研究

Effect of Potassium Chloride on Yield and Quality of Sugarcane

甘蔗施用氯化钾试验研究表明,甘蔗合理施用氯化钾不仅能明显提高产量和经济效益,而且对甘蔗品质也有良好的促进作用。但施用氯化钾时,务必讲究其用量,要控制在一定范围内,否则,不但会导致蔗糖分下降,还会造成减产。在合理施用氮、磷肥的基础上,以施K2O247.5～346.5kg/hm2为宜。

Test on the Effect of potassium chloride was conducted in sugarcane field and the results showed that rational application of potassium chloride could not only significantly improve productivity and increase economic benefit, but also improve cane quality. Special attention should be paid to its application rate; excessive usage would lead to a decrease of sucrose content and cane yield. K2O application rate of 247.5-346.5 kg/hm^2 was considered suitable on condition that adequate nitrogen and phosphate fertilizers were also applied.
