Abstract
A field test method was conducted to investigate the effects of different nitrogen sources on tobacco root growth and and available nutrient of rhizosphere soil of tobacco. The results showed that the root fresh weight of application of ammonium nitrate and phosphorus treatment than in urea treatment increased by 19.61% ,29.85% ,root oxidation increased by 23.11% , 13.68%,respectively,at budding stage and mature stage in the condition of equal amount of nitrogen;soil available nitrogen of the rhizosphere and non-rhizosphere increased by 10.38%,9.91%,respectively,at mature stage,available phosphorus increased by 16.06%,12.76% respectively,at budding stage and mature stage. Considering the application of ammonium nitrate and phosphorus is more than urea conducive to the growth of flue-cured tobacco.关键词
