摘　　要：比较了不同中微量元素及其复混物在坡岗地糖蔗上的应用效果。结果表明,配方肥配施不同中微量元素及其复混物对甘蔗分蘖数、茎粗无显著影响;添加Mg、B、Zn、Mn或中微量元素复混物显著增加了植株高度与商品茎长;施用Mg、B或中微量元素复混物后植株单茎重显著增加;施用Mg、Mn或中微量元素复混物能明显提高甘蔗产量,但配施Ca、Zn和B元素增产不显著甚至减产。建议在配方肥生产中应适当添加Mg、Mn元素以获得更高产量。Field trials were conducted to compare the effects of different secondary and micronutrients and the mixture （mixture of Ca, Mg, B, Zn and Mn） on sugarcane at hilly upland. Results indicated that, in combination with NPK-specific fertilizer, application of various secondary and micronutrients and the mixture, did not influence the number of tillers and the diameter of cane stems though, addition of Mg, B, Zn, Mn and the mixture significantly increased plant height and the length of commercial stem. Application of Mg, B and the mixture significantly increased single-cane weight, addition of Mg, Mn and the mixture significantly increased cane yields, however, addition of Ca, Zn and B did not increased or ever decreased yields to different extend. Therefore, addition of appropriate quantity of Mg and Mn was recommended in manufacture of the specific fertilizer for hilly upland sugarcane production in Guangdong.
