Three kinds of different media (peat∶vermiculite=1∶1;mushroom dregs∶vermiculite=1∶1;corn stalk∶vermiculite=1∶1)and fertilizing proportion(N∶P∶K=15∶5∶10,N∶P∶K=10∶5∶15,N∶P∶K=10∶5∶10）were used in Lily Sorbonne,Lily Siberia and Lily Marlon,during the growth period of scale bulb lets to small bulb lets,and the plant morphology,chlorophyll content,the size of bulb lets underground,the soluble carbohydrate as well as the dry matter of the lilies were observed,measured and recorded which was in order to find out the best growing media and fertilizing proportion in this paper.The results showed that different medium and fertilizing proportion had significant influence on the growth of lily bulb lets.Taking their plant morphologies,the size of bulb lets underground,the physiological and biochemical index and other relative factors into consideration,the best condition for both Lily Sorbonne and Lily Marlon were the corn stalk∶vermiculite=1∶1+N∶P∶K=10∶5∶15.Lily Siberia performed best under the same medium corn stalk∶vermiculite=1∶1 plus fertilizing proportion of N∶P∶K=15∶5∶10.
