Effect of 30Xiange Oceanic Bioactive Peptide Pesticide-Fertilizer on Sugarcane Pests,Sugarcane Yield and Sugar

摘要

[Objective]The paper was to study the effect of 30%Xiange oceanic bioactive peptide pesticide-fertilizer on sugarcane pests,sugarcane yield and sugar.[Method]With conventional compound fertilizer mixed with 3%carbofuran granulated insecticide as the control,the field effect of30%Xiange pesticide-fertilizer on sugarcane was compared.[Result]After the application of 30%Xiange pesticide-fertilizer for 90 d,the control effects on sugarcane borers in the two test points were 93.66%and 93.09%,respectively,which were significantly higher than those of conventional control(21.86%and 24.19%).Before harvest,the reduction effects of sugarcane internodes in the two test points treated by pesticide-fertilizer were6.21%and 5.10%,respectively,which were significantly lower than those of conventional control(36.25%and 34.55%).The control effects of Xiange pesticide-fertilizer on sugarcane chafer in the two test points were 91.34%and 100.00%respectively,which were significantly higher than those of conventional control(68.00%and 64.29%).The yields of sugarcane treated by Xiange pesticide-fertilizer in the two test points were107700 and 108000 kg/hm2,and the sugar contents were 15.62%and 15.55%,respectively.The yield and sugar content of sugarcane treated by Xiange pesticide-fertilizer were increased by 28.63%and 1.33%compared with those of conventional control.[Conclusion]30%Xiange oceanic bioactive peptide pesticide-fertilizer has good control effect on sugarcane pests,which could obviously increase yield and sugar of sugarcane.The product is worth being promoted and applied in sugarcane planting area.
