摘　　要：【目的】针对当前广西、广东果蔗产区普遍选用进口复合肥料的情况,选择不同国产复合肥料进行搭配试验,研究其对果蔗产量及经济效益的影响,为果蔗生产施用国产肥料提供参考依据。【方法】在N、P、K有效含量相同的条件下,3种国产复合肥单施及搭配施用,以目前蔗农应用较广的狮马牌进口复合肥为对照。【结果】:(1)在商品蔗长度、茎径、节间数、单茎重、单位面积产量等性状,国产复合肥料搭配处理优于或相近进口复合肥料处理,国产复合肥料单一施用处理低于进口复合肥料处理;节间长度以国产复合肥料单一施用处理最高,进口复合肥料处理最低;田间蔗汁锤度国产复合肥料搭配处理最高,进口复合肥料处理最低。各处理经方差分析差异不显著。(2)在经济效益方面,每666.7m2投入国产复合肥料搭配处理、单一施用处理均比进口肥料少373.0元。进口复合肥料处理销售收入高于国产复合肥料单独施用处理,差异不显著,纯收入相当。国产复合肥料搭配处理销售收入高于进口复合肥料处理,但差异不显著;其搭配处理纯收入显著高于进口复合肥料处理,平均比进口复合肥料处理增加纯收入1202.62元/666.7m2。【结论】在有效成分相同的条件下,2种以上国产复合肥搭配施用其单位面积产量、纯收入等均优于单独施用的进口复合肥,可在生产中推广应用。[Objective] In view of the current use of imported compound fertilizers （ICF） in chewing caneproduction areas of Guangxi and Guangdong, different domestic compound fertilizers were selected for collocationexperiments to study their effects on chewing cane yield and economic benefits, to provide references for theapplication of domestic fertilizers in chewing cane production.[Methods] Under the conditions of the same contentof N, P and K, three kinds of domestic compound fertilizers were selected for different combinations （single andmixed application）.Imported compound fertilizer of Lion-horse brand was used as control, which was widely usedin sugarcane farming at present. [Results] （1） Length of cane stem, stem diameter, internode number, single stemweight, and yield per unit area which derived from mixed domestic compound fertilizer （MDCF） treatment werebetter than or similar to that of ICF treatment. However, single domestic compound fertilizer （SDCF） treatmentswas lower than that of ICF treatment; the internode length was the highest in the SDCF treatments, and the lowestin ICF; cane juice brix from MDCF treatments obtained the highest, while the ICF treatment was the lowest. （2）The invested costs of both SDCF and MDCF treatment decreased by 373.0 yuan per 666.7 m2compared with thatof ICF treatment. The sales income of the ICF treatment was higher than that of the SDCF treatment, thedifference was not significant, and the net income was the same. The sales income of the MDCF treatment washigher than that of the ICF treatment, but the difference was not significant; the net income of the MDCFtreatments increased by 1 202.62 yuan per 666.7 m2compared with the ICF treatment, the difference wassignificant. [Conclution] Under the same conditions of effective active ingredients, the yield per unit area and netincome of two or more kinds of MDCF are better than those of ICF, which can be promoted and applied inchewing cane planting.
