Abstract: Based on pot experiments and field experiments , the mechanism and effect of desnlphurization byproduct on Eucalyptus nutrition are studied .The results are as follows :(1)When applying 4.15 gkg-1 desulphurization byproduct to eucalyptuses in basaltic latosol , nutrients of N , P , K , Ca , Mg , S and B absorbed by eucalyptuses are 61 %, 44 %, 39 %, 90 %, 81 %, 21 %, 146 % higher than those of controlled eucalyptuses .And the nutrients absorbed by eucalyptuses in neritic sedimentary latosol also increase greatly .It indicates that the applied byproduct can significantly improve the nutrition absorption of eucalyptuses .But when the quantity applied is over 8.03 gkg-1 or below 2.76 gkg-1 , the eflect of eucalyptus nutrition absorption will be restrained .(2)Both pot and field experiments show that applying of suitable quantity of desulphurization byproduct can promote eucalyptus growth and increase its biomass .When applying 4.15 gkg-1 desulphurization byproduct to eucalyptuses in basaltic latosol , the weights of root , stem and leaf are 118.75 %, 116.24 %and 63.92 %higher than those of eucalyptuses under control .And the weights of root , stem and leaf of eucalyptuses in neritic sedimentary latosol also increase greatly .But when the quantity applied is over 8.03 gkg-1 or below 2.76 gkg-1 , the effects will decline .(3) Proper use of desulphurization byproduct can prevent and cure tip-droop disease caused by the lack of trace elements .[ Ch , 2 fig .6 tab .11 ref.]
