Abstract:: Vegetation coils that planted with Amorpha fruticosa were used as research object.The law of used and unpolished of N,P,K in A.fruticosa Linn. was researched.Using five paclobutrazol concentration gradient(0.004,0.020,0.040,0.060,0.080 g?L-1).The effects of paclobutrazol on N,P,K use in A.fruticosa Linn.,and the effects of paclobutrazol on biomass in A.fruticosa Linn. were studied.The results showed that the loss rate of N,P,K in vegetation coils with a rapid speed because of single component in the matrix.In the seven destructions test,loss nitrogen in matrix was 22.4%,phosphorus loss was 15.9%,potassium loss was 25.4%.There were big differences between the effects of paclobutrazol on N,P,K fixed and the effects of paclobutrazol on biomass in A.fruticosa Linn.. A.fruticosa Linn.at a concentration of 0.080 g?L-1 paclobutrazol had the most use in N,P,K,but paclobutrazol concentration of 0.040 g?L-1 had the maximum biomass in A.fruticosa Linn..
