[目的]探求生物炭对大田新植甘蔗生长的效应，从而为甘蔗生产上应用生物炭和制定氮肥高效管理提供理论基础。[方法]试验以甘蔗品种'GT11'和'B8'为材料，设置低氮 N 120 kg/hm2 和高氮N 600 kg/hm22 个氮水平，生物炭C0、C10 和C20 t/hm23 个水平，调查测定炭氮配施对甘蔗农艺生长、氮积累量和氮利用率及产量构成因素的影响。[结果]生物炭可适当增加甘蔗出苗率、分蘖率和株高，生物炭虽对产量增加无明显效应，但能够提高甘蔗糖分0。19%～0。82%，从而使产糖量增加了 1。93%～10。77%。高炭处理下甘蔗氮累积量增加了0。41%～4。74%，但对氮利用率未起到显著提高作用。[结论]生物炭对新植甘蔗的分蘖、氮累积量及糖度累积起到了一定的促进作用，但这种效应因品种而异，氮在其中的作用大于生物炭的作用。
Effects of Co-application of Biochar and Nitrogen Fertilizer on Agronomic Characters and Nitrogen Use Efficiency of New Planting Sugarcane
[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.
