摘　　要：[目的]为今后抗旱型甘蔗专用肥的研制及大田生产应用提供科学的依据。[方法]用不同肥料品种、保水剂配制成2种类型的4种抗旱型甘蔗专用肥,与常规施肥方式对比,研究其在甘蔗上的施用效果。[结果]施用抗旱型甘蔗专用肥出苗率比对照增加1.6%～9.7%,株高增加2～20 cm,有效茎增加3 871～12 651条/hm2,蔗茎产量比对照增产5.14%～15.01%,蔗糖分提高0.12～0.46个百分点,经济效益比对照增加515～3 538元/hm2。[结论]施用抗旱型甘蔗专用肥能促进甘蔗出苗、分蘖及蔗茎伸长,增加有效茎数,提高产量和蔗糖分,并获得较好的经济效益。采用尿素、磷酸一铵、氯化钾3种肥料和BJ2101L保水剂配制而成的抗旱型甘蔗专用肥的施用效果最好。[ Objective ] To provide a scientific basis for development of drought resistant sugarcane special fertilizer and field production application in future. [ Method] Four kinds of drought resistant special fertilizer of two types was configured by different varieties of fertilizer and water retention agent, the application effect was studied compared with conventional fertilization method. [ Result ] Compared with CK, the sprouting rate, plant height, millable stalk, cane yield, sucrose content and the economic benefit by applied drought resistant sugarcane special fertilizer incresed 1.6% - 9.7% , 2 - 20 cm, 3 871 - 12 651 strips, 5.14% - 15.01%, 0.12% - 0.46% and 515 - 3 538 yuan/hm2, respectively. [Conclusion] The germination, tillering and stalk elongation were promoted by applied drought resistant special fertilizer, increase millable stalk, yield and sucrose content, obtain better economic benefi. The best application effect was found in drought resistant special fertilizer, which was configured by urea, monoammonium phosphate, potassium chloride and BJ2101L water retention agent.
