Abstract:In order to explore effects of application of medium-or micro-elements, such as Ca, Mg, B, Mo, Fe, Cu and Zn, on yield and sugar content of sugarcane, they were applied separately in sugarcane fields in Leizhou Peninsula, where the soil is latosol, originating from basalt. The experimental results show that Ca, Mg, B and Mo increased significantly sugarcane yield, but Fe decreased sugarcane yield. At the same time, B, Mo, Fe and Cu increased sugar content of the sugarcane. In addition, the effect of mixed application of Ca, B and Mo on yield and sugar content of sugarcane was not any better than that of the application of the three elements separately. The experiment indicates:significant economic benefit of sugarcane production may be obtained if only one of these fertilizers, B, Mo and Ca is applied in sugarcane field. Accordingly, a suggestion is made that Mo, B and Ca fertilizers be applied separatelty if the soil of the sugarcane field is latosol, originating from basalt.
