摘　　要：为考察药肥混剂施用对糖料蔗生产的效果,分别采用药肥混剂、药肥拌匀施用、药肥分施3种方式对新台糖22号和福农39号2个甘蔗品种进行田间试验。结果表明,在病虫害防治上药肥混剂对2个甘蔗品种的效果相当,均优于其他处理,但新台糖22号比福农39号的理论产量高8.4 t/hm^2。因此选择新台糖22号为研究对象,继续比较药肥混剂、药肥拌匀施用与药肥分施(CK)对其作用效果。结果表明,相对于药肥分施,药肥混剂表现出更优的效果,萌芽率高15.38%,甘蔗蓟马为害率低15%,生长速度相差不大,理论产量高17.7 t/hm^2,纯收益高9048元/hm^2。在糖料蔗生产上施用药肥混剂省时省力,具有较好的病虫防治效果,能在一定程度上提高糖料蔗产量,增加生产效益,具有一定的推广应用价值。In order to investigate the application effect of insecticide-fertilizer mixture on sugarcane production,field trials were carried out on 2 sugarcane varieties,Xintaitang 22 and Funong 39,by insecticide-fertilizer mixture,mixed application of insecticide fertilizer and divided application of insecticide fertilizer.It was found that insecticide-fertilizer mixture had similar effect on disease and insect pest control in the planting process of the two sugarcane varieties,which was better than the other control groups,but the theoretical yield of Xintaitang 22 was 8.4 t/hm 2 higher than that of Funong 39.Therefore,Xintaitang 22 was selected as the research object to continue to compare the application effect of insecticide-fertilizer mixture and divided application of insecticide fertilizer.The results showed that insecticide-fertilizer mixture showed better effects compared with the divided application of insecticide fertilizer,with a higher germination rate of 15.38%,a lower harm rate of cane thrips of 15%,a similar growth rate,a higher theoretical yield of 17.7 t/hm 2 and a higher yield of 9048 yuan/hm 2.The application of insecticide-fertilizer mixture in sugarcane planting not only saved time and labor,but also had a good effect on the disease.To a certain extent,it can improve the yield of sugar cane,increase the production efficiency,and has a certain value of popularization and application.
