摘　　要：在土壤有效B、Mn、Cu含量缺乏的稻田上种植甘蔗,以测土氮磷钾配方肥(N 379.5kg/hm^2、P_2O_5168.0kg/hm^2、K_2O 570.3kg/hm^2)、生物有机肥(2250kg/hm^2)为基础(CK),配施硼锰铜复合微肥(0、75、112.5、150、187.5kg/hm^2)5个处理,研究其对甘蔗的效应。试验结果,在配施硼锰铜复合微肥4种水平中处理4效果最好,产量比处理1、2、3、5增加48.5%、24.3%、11.7%、2.5%,糖分提高1.0、0.6、0.5、0.2个百分点,产糖量提高57.6%、28.8%、15.1%、3.7%,经济效益提高54.0%、26.7%、12.8%、2.9%;从产量效益看,硼锰铜复合微肥配施量以150kg/hm^2为宜。建议我国南方类似地区参考应用。Sugarcane were planted in paddy fields lacking available B,Mn,Cu with five treatments of boron-manganese-copper compound fertilizer(BMCCF)applied amounts0,75,112.5,150,187.5kg/ha,based on nitrogen-phosphorus-potassium formula fertilizer by soil testing(N379.5kg/ha,P2O5168.0kg/ha,K2O570.3kg/ha)and organic fertilizer(2250kg/ha),which was as the control.The test results showed that the150kg/ha BMCCF treatment had best effect,cane yield increased by48.5%,24.3%,11.7%,2.5%,sugar content increased by1.0,0.6,0.5,0.2percentage points,sugar yield increased by57.6%,28.8%,15.1%,3.7%,and the economic benefit increased by54.0%,26.7%,12.8%,2.9%,in compassion with that of0,75,112.5and187.5kg/ha,respectively.According to the yield profit,appropriate amount of BMCCF was150kg/ha in sugarcane,and suggested to apply in the similar south area of China.
