【文章內(nèi)容簡介】 he canopied photosynthetic characteristics and photosynthetic productivity and were good for drymatter production and sugar with CK,the nitrogen and potassium accumulation amounts of BIO treatment were obviously higher than CK in later developmental stage,at the same time,BIO affected nitrogen and potassium distribution in different organs and more nutrients flowed to tobacco leaves,which were the?major cause why the contents of nitrogen and nicotine and potassium within tobacco leaves under BIO treatment were obviously higher than those of significantly proved physiological activity of tobacco roots and increased ability of absorbing mineral nutrients in root. Compared with CK,oxidizing ability of root and activity of root system under BIO treatment were increased by % and % significantly increased the total content of NAC in tobacco leaves by % % pared with CK. The total content of NAC at different position of tobacco leaves had dramatically different reaction to BIO,namely,the biggest increase was observed in the upper leaves,and the total content of NAC in upper leaves,middle leaves and bottom leaves were increased by %,% and % respectively pared with CK. BIO application also changed the orders of the total content of NAC in tobacco leaves at different positions,the order of u
