OBJECTIVE： To study the accumulation and distribution characteristics of nitrogen （N）， phosphorus（P） and potassium （K） in Scrophularia ningpoensis at different growth stages， in order to provide theory evidence for the establishment of scientific fertilization technique for S. ningpoensis. METHODS： In field testing， through the dynamic sampling of S. ningpoensis at seedling stage， stem and leaves growth stage， root enlargement stage and root enrichment stage， the contents of N， P and K were measured， and the accumulation and distribution regularity of N， P and K in stem， leaves， root， rhizome and bud were also studied. RESULTS： The accumulation of mineral elements in seedling stage of S. ningpoensis was less， the absorptive capacity of N， P and K accounted for 13.8％， 13.2％， 14.0％ of the whole growth periods； the plants grew vigorously at stem and leaves growth stage， root enlargement stage， and the absorptive capacity of N， P and K accounted for 86.2％， 85.2％， 86.0％ of the whole growth periods； the plants drooped and languished at root enrichment stage， and the absorptive capacity of N， P and K appeared a downward trend. The allocation proportion of N， P and K at seedling stage， stem and leaves growth stage and root enlargement stage were always leaf＞stem＞root＞rhizome＞bud， especially focusing on stem and leaves. In the later period of root enlargement， roots replaced the aerial part of plants to be the center of growth， and the accumulation of N， P and K shifted from the stem and leaves to the roots. During growth period， the demand of N and K were the highest， followed by P. The dry weight of S. ningpoensis was positively correlated with the total accumulation of N， P and K（R2 were 0.844，0.959，0.827）. CONCLUSIONS： The stem and leaves growth stage and root enlargement stage are the most crucial period of the absorption of N， P and K. It should be paid more attention to the supply of mineral nutrition to meet the requirement of plant. Under medium nutrition condition， the average N， P and K absorption amount per 100 kg try medicine are 7，0.73 and 6.5 kg respectively.
