    摘要:

    在雷州半岛玄武岩发育的种植甘蔗砖红壤上施用Ca、Mg、B、Mo、Fe、Cu、Zn肥料,探究这些中量与微量元素对甘蔗的产量与糖分的效应。结果表明:Ca、Mg、B、Mo肥对甘蔗有显著增产效应,而Fe肥具有显著减产效应。B、Mo、Fe、Cu肥能显著提高甘蔗含糖量,而Mg肥具有降低甘蔗糖分的效应。Ca、B、Mo 3种肥料相互配施的增产或增糖效果均不优于单施的效果。从对甘蔗产量和含糖量综合效果看,甘蔗施用B、Mo、Ca肥分别能产生显著经济效益。因此,在玄武岩发育砖红壤上种植甘蔗,建议施用Mo、B、Ca肥。

    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.
