| Abstract: | A pot cultural experiment was conducted in 1988 and 1989. Using ~(15)N as a fracer with different rates fertilizer nitrogen in flue-cured tobacco,the authors examined the source of nitrogen, the content of absorbing, the utilization rate of nitrogen fertilizer and the influence to the fixed content and An Value of soil;they also discussed some rules of nitrogen nutrition in flue-cured tobacco, offering reference for applying fertilizer appropriately. |
