Abstract
Effects of C/N regulated corn straw application on the flue-cured tobacco yield,output value and nitrogen,phosphorus and potassium concentration in the upper,middle and bottom leaf and cumulative uptake were studied by using the field plot experiments in Banqiao town,Qujing city,Yunnan Province during the 2008-2009 summer growing seasons.The results showed that the application of corn straw after C/N regulation could significantly increase tobacco production,nitrogen and potassium uptake of leaf.In particular,it was better with application of oilseed cake or vetch or other high-nitrogen biomass carbon and corn straw after C/N regulation.The yield of tobacco increased by 11.53%,9.49% and 3.73%,respectively,with application of corn straw and vetch,corn straw and oilseed cake,corn straw and urea nitrogen,compared with corn straw alone,the nitrogen concentration in tobacco leaf increased by 12.95%,4.80%,and 7.76%,the total nitrogen cumulative amount increased by 26.15%,15.02%,and 11.79%,the potassium concentration increased by 4.11%,5.24%,and 7.79%,the total potassium cumulative amount increased by 16.10%,15.23%,and 11.81%,respectively.However,the phosphorus uptake of tobacco leaf decreased,and the application of corn straw alone reduced tobacco production,output and nutrient uptake.Therefore,the application of high C/N ratio corn straw in flue-cured tobacco production,which should be concerned not only to adjust C/N ratio by adding nitrogen,but also considering additional phosphorus application.
