Title: EFFECTS OF DIFFERENT FERTILIZER ON THE YIELD,QUALITY OF FLUE-CURED TOBACCO AND THE PHYSICAL CHARACTER OF SOIL
Abstract: The effects of fertilization on the growth,development,yield,quality of fluecured tobacco and physical character of soil were studied through field trials by the randomized block design.The results showed that as compared with the equal chemical fertilizer(T2),tobacco special fertilizer could improve the physical character of soil and ensure growth steadily to form perfect plant figure.It decreased protein content and the difference between total sugar and reducing sugar,while harmonizing the ratio of nitrogen to nicotine and the ratio of total sugar to nicotine,so it improved the chemical quality of leaves.But there was no difference in the yield of total leaves and mid-upper leaves..Compared with the T2,applying NO-3-N and NH4+-N synchronously could increase the yield of total leaves and mid-upper leaves significantly.It decreased the protein content and had an appropriate ratio of nitrogen to nicotine and the ratio of total sugar to nicotine,so it improved the chemical quality of leaves.
