In 1999~2000,field experiments were conducted to study specific bioactivated organoinorganomixed fertilizers on fluecured tobacco in Hunan .The results show that application of specific bioactivated organoinorganomixed fertilizers, can promote growth of root of system and development of root activity by 8.1%~20.7%,and the activity of nitrate reductase increased by 13.3%~14.8%. Theplantgrowsbetter,leavesgrowmorequicklyandthe amount of available leaves enhanced per plant. Therefore, the yield increases by 2.7%~10.8%, the rate of high quality of tobacco leaves rise by 33.3%~102.3%, and the output value increases by 14.3%~26.9%. The inner quality of leaves get ever more coordination and improvement , and nicotine content decreases by 4.5%~18.2%,while reducing sugar content increases by 12.6%~16.5%, and amylum content decreases by 4.4%~10.5%.
