Embodiment 1
[0034] Investigate the influence of the scales of bulbs with different specifications on the development of small bulbs.
[0035] 1. Cultivation of small bulbs
[0036] Choose finely crushed fresh peat soil as the substrate, and mix 100g of 55% dexon powder and 100g of 40% pentachloronitrobenzene powder per cubic meter of substrate for later use. In mid-September, select and mark the robust oriental lily plants in the field. Harvest the marked plants in late October, select healthy bulbs with sizes of 14-16 cm, 16-18 cm, and 20-22 cm, and reserve them by variety and size. Rinse the bulb with clear water, and then separate the 3 layers of scales counting from the outside to the inside. The separated scales are first fully cleaned with clean water, then soaked in a mixed suspension containing 0.4% carbendazim, 0.2% chlorothalonil, and 0.1% chlorothalonil for 15 minutes for disinfection, and the soaked scales are air-dried in a clean environment until No moisture on the surface...
Embodiment 2
[0048] Under the same treatment conditions, the difference between the peripheral scales of Lilium orientalis and the scales of the central main bud to differentiate into bulblets was investigated.
[0049]Repeat embodiment 1, have following difference: select the healthy bulb of specification 16~18cm, sub-kind is standby. After cleaning, 5 layers of scales were counted from the outside to the inside, the outermost 3 layers were used as the outer scale test group, and the other two layers were used as the inner scale test group. Each group was set with one repetition, and each group had 50 scales. After heat treatment, the situation of scale differentiation into small bulbs is shown in Table 4.

Embodiment 3
[0054] To investigate the effect of splitting time on the aboveground stem differentiation of small bulbs.
[0055] Repeat Example 1, with the following differences: since mid-August, sampling and fragmentation are carried out every 20 days, and 40 heads of each variety are harvested, and 20 healthy bulbs with a specification of 16-18cm are selected, divided into varieties. For standby, after cleaning, separate 5 layers of scales counting from outside to inside, set up test groups in chronological order, set up 1 repetition for each group, and set 50 scales in each group. The cleaned scales are disinfected by soaking in a mixed suspension containing 0.4% carbendazim, 0.2% chlorothalonil, and 0.1% chlorothalonil for 30 minutes. After the cold treatment, the bulbs were classified according to the varieties and test groups, and the small bulbs together with the connected scales were planted on the seedbed immediately. The planting results are shown in Table 5.
