摘　　要：通过对任豆容器实生苗进行N、P、K配比施肥试验,研究其在不同施肥处理下叶片数、叶面积、生长量、生物量等的特征变化。结果表明:不同施肥处理对任豆容器苗的苗高、地径、叶片、叶面积、生物量等影响显著;NPK平衡施用对任豆容器幼苗生长的促进作用最大,为最优施肥处理;经过4次施肥后,NPK处理苗木的苗高、地径、叶片数、叶面积、地上鲜质量、地下鲜质量、地上干质量、地下干质量的生长量分别是CK苗木生长的211.4%、154.2%、161.7%、327.5%、568.3%、423.5%、405.8%、275.0%。The experiment of nitrogen（N）,phosphorus（P）,potassium（K） fertilizer on container seedling of Zenia insignis was conducted to study the effects of fertilization on the growth of seedlings.The results showed that the fertilization had significant influences on the height,diameter,leaf number,leaf area and biomass of the seedlings.The NPK balance fertilization was the best treatment in which the growth of container seedling of Z.insignis was greatly promoted.After four times fertilization,the height,diameter,leaf number,leaf area,the ground and thr underground fresh weight,the ground and the underground dry weight of the seedlings in N,P,K balance treatment was increased by 211.4%,154.2%,161.7%,327.5%,568.3%,423.5%,405.8% and 275.0%,respectively compared with the control.
