摘　　要：【目的】研究30%贤哥海洋生物肽药肥对甘蔗害虫的田间防效及其对甘蔗产量糖分的影响。【方法】以常规复合肥加3%呋喃丹颗粒杀虫剂为对照肥药,进行30%贤哥药肥在甘蔗上的田间效果对比试验。【结果】田间对比试验结果表明,30%贤哥海洋生物肽药肥处理后90 d,两个试验点其对甘蔗螟虫的防效分别为93.66%和93.09%,显著高于常规对照防效(21.86%和24.19%);收获前,两个试验点贤哥药肥处理甘蔗螟害节率分别为6.21%和5.10%,显著低于常规对照的螟害节率36.25%和34.55%;两个试验点贤哥药肥处理对甘蔗金龟子的防效分别为91.34%和100.00%,显著高于常规对照防效(68.00%和64.29%);两个试验点贤哥药肥处理甘蔗产量分别为107700、108000 kg/hm^2,甘蔗糖分分别为15.62%和15.55%,较常规对照增产28.63%,增糖1.33个百分点。【结论】30%贤哥海洋生物肽药肥在甘蔗上防虫效果优良,增产增糖效果显著,值得在蔗区推广应用。【Objective】The objective was to study the effect of 30%Xiange oceanic bioactive peptide pesticidefertilizer on sugarcane pests prevention,yield and sugar.【Method】With conventional compound fertilizer and 3% carbofuran granulated insecticide as control,a comparative test of the field effect of 30%Xiange pesticide fertilizer on sugarcane was carried out.【Result】The results showed that after the application of 30% Xiange pesticide-fertilizer for 90 d,the control rates on sugarcane borer in the two test points were 93.66% and 93.09%,respectively,which were significantly higher than the rates of 21.86% and 24.19% of the control.Before harvest,the reduction rates of sugarcane borer in the two test points under pesticide-fertilizer treatment were 6.21%and 5.10%,respectively,which were significantly lower than the rates of 36.25% and 34.55% of the control.The control rates of Xiange pesticide-fertilizer on sugarcane chafer in two test points were 91.34% and 100.00% respectively,which were significantly higher than the rates of 68.00% and 64.29% of the control.The yields of sugarcane treated with Xiange pesticide-fertilizer at two test points were 107700 kg/hm^2 and 108000 kg/hm2,respectively,with the sugar contents of 15.62% and 15.55%,respectively.The yield and sugar content of sugarcane treated with Xiange pesticide-fertilizer increased by 28.63% and 1.33% compared with those of the conventional control treatment.【Conclusion】30% Xiange oceanic bioactive peptide pesticide-fetilizer has good effect on sugarcane pests control,which would obviously increase yield and sugar.It is worth being promoted and applied in sugarcane planting area.
