摘要
在花岗岩、砂页岩母质发育的砖红壤、赤红壤上种植甘蔗新台糖25号,研究单配施或相互配施钙、镁肥对甘蔗产量与糖分的效应。结果表明,单配施Ca肥较单配施Mg肥增产效果好,但单配施Mg肥对提高甘蔗糖分含量较单配施Ca肥明显;Ca、Mg两种肥料相互配施的增产或增糖效应比单配施的效果显著。因此,在花岗岩、砂页岩发育的砖红壤、赤红壤上种植甘蔗,建议Ca、Mg肥相互配施,争取更好的效益。
In order to explore effects of applying single and both calcium and magnesium fertilizer in the latosol and lateritie red earth, the sugarcane ROC 25 was tested on yield and sugar content of sugarcane, they were applied. The results showed that： the yield of single calcium fertilizer was higher than that of applying single magnesium fertilizer, but the sugar content was increased significantly the single magnesium fertilizer for using in comparison with single calcium fertilizer. In addition the effect of mixed application of both calcium and magnesium fertilizer on yield and sugar content of sugarcane was better than the application of the two fertilizers alone. Therefore, mixed application of calcium and magnesium fertilize in the atosol and lateritie red earth was suggested for better benefit.
