Abstract: Trails on the effects of various nutrition supply conditions on Acer truncatum were conducted. The size of plant, branching pattern and biomass of 2 years old A. truncatum under 9 different treatments were measured and analyzed. The result showed that the different nutrition supply conditions significantly affected the architecture of A. truncatum. This leaded to significant different on growth, biomass and distribution of A. truncatum. Fertilization treatments should be selected by cultivation aims. The treatment N0P250K75 was the best for horticulture tree cultivation with basal diameter of 2.85 cm, height of 1.26 m, crown of 0.59 m2, which were respectively 34.26%、51.66% and 140.23% higher than that of non-fertilizing treatment. The treatment N0P125K37.5 was the best for foliage-usage forest cultivation with total biomass dry weight of 438 g, root biomass dry weight of 192 g, stem and branch biomass dry weight of 159 g, leaf biomass dry weight of 88 g, which were respectively （83.42%）、60.10%、98.13% and 113.44% higher than that of non-fertilizing treatment. Its root/shoot biomass dry weight was （0.81）, which was 18.30% less than that of non-fertilizing treatment.
