This study was conducted in 2009 and 2010 in Shandong in Zhucheng, wulian and Mengyin validated by \Shandong flue-cured tobacco suitable nutrient usage and fertilization parameters. The main findings are as follows: 1, different soil types (Cinnamon Soil and Chao brown), different N, P, K ratio for Tobacco 100 Tobacco 203 agronomic traits and biological characteristics, mainly in N vegetarian effect with increasing application rate on the growth and development of the tobacco plant, promote, especially obvious impact on whether or not to applied N not applied nitrogen fertilizer processing performance is poor, the the P prime effect and K prime effect smaller. 2, the use of different soil types and different flue-cured tobacco varieties \fertility region N, P, K fertilization: the N 4-6 kg/667m2, the P2O5 5-8 kg/667m2, K2O 5.5-9 kg/667m2; the proposed smoke 203 varieties in the region of N, P K fertilization were: N 4-6 kg/667m2-P2O5 5-6.5kg/667m2 of K2O 7-10kg/667m2 3 areas in fertility different N, P, K ratio Tobacco 100 Junior Tobacco Leaf Tobacco 203 varieties have some intrinsic quality. Tobacco 100 Cured Tobacco Leaves in the alkali content of total nitrogen and total plant increased with increasing amount of nitrogen; phosphate fertilizer application rates on the initial content of the chemical composition of flue-cured tobacco leaf regularity; with potash consumption improve, cured tobacco in reducing sugar, total sugar content first increased and then reduced, K2O more elevated Cl content decreased. Tobacco 203, with the increase in the amount of nitrogen fertilizer, reducing sugar, total sugar content and sugar to nicotine ratio decreased gradually increase total plant alkali content, total nitrogen content was increased first and decreased trend; phosphorus fertilizer application on cured tobacco chemical ingredients is not obvious; gradually increased with increasing K fertilizer plant alkali content, the amount of potassium K2O content of the highest in the of 12 kg/667m2 processing tobacco, potassium 18 kg/667m2 processing tobacco highest chlorine content, to handle 8 processing potassium chloride potassium than the largest proportion. 4, the application of the \intrinsic quality, thereby increasing the proportion of the middle and upper smoke, higher output and profits.
