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。Abstract: In order to study the effects of 30% tiange multifunctional 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 multifunctional 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.
