摘　　要：以甘蔗生产上施用常规复合肥与呋喃丹颗粒杀虫剂为对照,研究30%甜歌多功能药肥对甘蔗害虫的田间防效及甘蔗产量的影响。结果表明,30%甜歌多功能药肥能够有效的抑制甘蔗螟虫、蓟马、绵蚜、金龟子等害虫的发生。药肥施用后90 d,两个试验点的甘蔗枯心率分别为1.55%和2.55%,显著低于对照处理的15.40%和19.40%;收获前,两个试验点药肥处理的甘蔗螟害节率分别为8.70%和9.47%,显著低于对照处理的34.50%和33.50%,且甘蔗产量较对照处理分别高21.16%和22.14%。30%甜歌多功能药肥兼具营养与杀虫双重功效,两者合二为一,实现甘蔗药肥一体化生产,达到省工节本的目的。In order to study the effects of 30% tiange muhifunctional medicinal-fetilizer on the control efficiency of pests and sugarcane yield, the field tests were conducted with conventional fertilizer and pesticide as control. The results showed that 30% tiange muhifunctional medicinal-fetilizer could effectively control sugarcane borers, thrips, woolly aphid and chafer. After 90 days, the withered heart rate of sugarcane in two test points were 1.55% and 2.55% respectively, which were significantly lower than that in the control group. Before harvest, the rate of borer section of sugarcane in two test points were 8.70% and 9.47% respectively, which were significantly lower than that in the control group. In addition, it made sugarcane yield increased by 21.16% and 22.14%. 30% tiange multifunctional medicinal-fetilizer had double effects of nutrition and insecticide, would realize the integrated production of sugarcane pesticide and fertilizer and save cost.
