Abstract: In the field cultivation process,Lilium spp. has a problem of weak plant growth, small growth of the globules and low sphericity. In order to improve the quality of the sub-balls,the scales of the lily varieties Siberia,Sorbonne and Conca d’or were used as test materials,and two cultivation methods of scale cultivation and descaling cultivation were carried out. The results showed that the germination time of the cultivars of the three cultivars was 3 days earlier than that of the squamous cultivars,and the twitch rate was increased by 7.33%,4.33%,15.43%,and the height of the globules was increased by 3.9, 2.7,1.6 cm. The effects of scale cultivation on the circumference and weight of the three specie on the circumferences and weights of three cultivars were significant. The diameter of the subspheres increased by 28.2%,32.6%,24.1%,and the weight of the subspheres increased by 20.1%,25.4% and 48.5%,respectively. The scaly cultivation can promote the growth of lily bulbs and improve the quality of the pellets,which has guiding significance for the commercial production of lily bulbs.
