Abstract: The characteristic of nutrient absorption and distribution in lily (Longiflrorum and Asiatic hybrids ‘Evening Star’) were investigated during the bulblet swelling development, the circumference of which is 4～6cm. The results indicated that nutrition element stored in bulblet was consumed for new leaves and stem growing before plantlet stage. From plantlet stage to harvest stage, the Nitrogen，Phosphorus and Potassium element was continuously being absorbed in by lily. The period of the most rapid nutrient absorption was from the half-withering stage to the harvest stage last about thirty-seven days, during which the absorption ratio of N. P. and K was 1:0.14:1.09. Before the flower bud appearance, the absorbed nutrient elements mainly allocated to leaves and stem. And the concentration of N. P. and K. reached their peak in every parts of lily plant at plantlet stage. Twenty-two days later after removing flower bud at visible bud stage, more and more uptake nutrient elements deposited to the swelling bulblt. The nutrient elements. Only about ten percent of the nutrient elements in lily was allocated to roots and the daughter bulblets.
