| Abstract: | In greenhouse,16 nutrient treatments were conducted in latored soil,with Eucalyptus grandis Hillex Maiden. The 16 treatments were CK(no nutrients,control),P,N,K,NP,PK,NK,NPK,A(-NPK modified UWA stock solution),NA,PA,KA,NPA,PKA,NKA and NPKA. The results showed that there were significant differences in seedling height,diameter and biomass production between 15 nutrient treatments and control(CK);Except the height of single P treatment,all indexes(height,diameter and biomass) of the treatments with P nutrient were more than those of the treatments without P nutrient,and there were significant difference in height,diameter and biomass between the treatments with P nutrient and the treatments without P nutrient;The rates of height/diameter of treatments with P nutrient were all less than that of the control treatment,on the contrary,the rates at single N,K,A and their combined treatments were all more than that of control treatment; Based on height, diameter, biomass above ground, root biomass and total biomass,by the Multiple Objective Strategic Decision Analysis methods,16 nutrient treatments were optimized and arranged from the excellent to the poor:NPKA>PKA>PA>NPA>NPK>PK>NP>P>KA,NKA>NK>K>NA>N>A>CK. Meanwhile,their distribution relationships among different parts of biomass were described. |
