Bulb propagation of lily
Lily seed life is very short, storage half a year will lose germination ability, and sowing seedlings need to cultivate for many years before flowering. After sowing, lily must be cultivated for several years to obtain commercial bulbs. Therefore, the general use of asexual reproduction to obtain seed balls, and then seed balls planted into the field to grow into commercial lily. Seed bulbs are first cultured into small bulbs of 50 ~100 g with various propagation materials, and the required years vary according to different propagation organs. The following is a brief introduction to the method of bulblet cultivation.
The method of bulbil cultivation is suitable for varieties producing bulbil, such as lily varieties. Mature bulbils were harvested in summer. From late September to early October, 4 cm deep sowing furrows were opened according to the row spacing of 12 cm ~15 cm. One bulbils was sown every 4 cm ~6 cm in the furrows, and about 3 cm soil was covered after sowing. Before freezing, soil was cultivated and covered with grass to ensure safe winter. In the spring of the second year, the covered grass and film were removed when seedling emerged, intertillage and weeding were carried out, and proper watering and topdressing were carried out to promote vigorous growth of seedlings. After the aboveground part withers in autumn, small bulbs are dug out, sown according to the row spacing of 30 cm and the plant spacing of 9 cm to 12 cm, and the soil thickness is about 6 cm. After cultivating for another year according to the management method of the previous year, seed bulbs reaching the standard size can be harvested in autumn, and some small bulbs that do not meet the standard can be continuously cultivated.
This method is only suitable for sand purple lily with bulbils. In summer and autumn, mature bulbils are collected and then dished. Bulblets can be formed in the same year, germinated in the spring of the next year, dug up and planted in autumn, and most of them can bloom after 3 years.

Storage and fresh-keeping Technology of Lily
Lily is more warm and afraid of cold, the scales will turn red and wither after the wind. There are many storage methods, especially the method of burying yellow sand is better. The specific approach is: use bricks or cement to build a burial pit indoors, or use wooden boxes, baskets, etc., as containers, and spread a layer of yellow sand at the bottom of the container, which is about 20 mm thick, and then a layer of yellow sand, piled to about 50 mm from the mouth of the container. Cover it with yellow sand to keep the lilies from being exposed to the air. In this method, it should be noted that the storage container should be used 0 in advance.

Planting and topdressing of Lily
Planting: ① digging trenches: the direction of the trench is perpendicular to the direction of the border, and the ditch depth is 5-10 cm. ② seed ball: pay attention to protect the new root. ③ cover soil: the soil cover should be slightly higher than the border surface, in order to preserve soil moisture and drainage. Topdressing: ① mainly contains nitrogen and potassium chemical fertilizer, can also use some liquid organic fertilizer, such as bean cake water and so on. Lily generally does not apply phosphate fertilizer, which can be provided by organic fertilizer. ② fertilization period. One month after emergence, bean cake water and 0.5% ammonium sulfate were applied, and 0.2% potassium salicylate and 0.2% ammonium sulfate were mixed. After the bud appears, it can be outside the root.
