生物炭与氮肥共施对甘蔗产量和糖分质量的影响
Effects of Co-application of Biochar and Nitrogen Fertilizer on Agronomic Characters and Nitrogen Use Efficiency of New Planting Sugarcane
摘要
Abstract
[Objective]The purpose of this study was to explore the effects of biochar on the growth of newly planted sugarcane,providing a theoretical reference for the application of biochar and efficient nitrogen fertilizer management in sugarcane production.[Methods]Two sugarcane varieties'GT11'and'B8'were chosen as trial materials.Two nitrogen(N)fertilizer levels were set:low N 120 kg/hm2 and high N 600 kg/hm2.Three levels of biochar were applied:C0,C10 and C20 t/hm2.The effects of carbon/nitrogen co-application on the agronomy growth of sugarcane,N accumulation,nitrogen utilization efficiency(NUE)and yield components were investigated.[Results]The results showed that biochar could increase the emergence rate,tillering rate and stalk height of sugarcane appropriately.Although no increase was observed in yield,sucrose content was increased by 0.19%-0.82%,resulting in an increase range of 1.93%-10.77%in sugar yield.High biochar application could improve N accumulation up by 0.41%-4.74%.However,there was no significant improvement in NUE.[Conclusion]Therefore,it was concluded that biochar partly promoted tillering rate,N accumulation and sugar yield of newly planted sugarcane,but these effects were different depending on varieties.And the study indicated that nitrogen play a more important role than biochar in sugarcane growth.关键词
