Abstract: 【Objective】To explore the effect of inorganic carbon fertilizer on wheat growth and carbon supplement.【Methods】Under the condition of ensuring the same nitrogen supply level,pot experiment was conducted to analyze the effects of ammonium bicarbonate application on wheat growth and total carbon accumulation by taking ammonium nitrate as control and sampling at 2,5,10 and 30 days after topdressing.【Results】Application of inorganic carbon fertilizer promoted the growth of wheat. Compared with the control,the plant height,leaf area,fresh weight and dry weight increased by 0.36%-9.45%,6.15%-19.95%,3.81%-20.80% and 3.13%-29.65% respectively at 5,10 and 30 days after topdressing. Application of inorganic carbon fertilizer had impacts on the total carbon accumulation in wheat plants. Compared with the control,the total carbon content in wheat increased by 0.17%-0.68% and the total carbon accumulation increased by 3.83%-28.82% at 5,10 and 30 days after topdressing.【Conclusion】The carbon in the inorganic carbon fertilizer ammonium bicarbonate could be absorbed and utilized by wheat,to participate in the process of carbon metabolism,and promote the growth of wheat.
