Embodiment 1
[0018] Example 1 Three-factor test of hormone type, hormone concentration-time, and cutting substrate
[0019] 1.1 Three-factor experiment of hormone type, hormone concentration-time, and cutting substrate
[0020] Two-year-old semi-lignified shoots were used as cuttings, and a three-factor randomized block experiment design was adopted. The test factors were: hormone type (IBA, ABT1 and NAA), hormone concentration and treatment time (100mg / L treatment for 2h, 200mg / L treatment for 1h and 1000mg / L treatment for 10s), cutting substrate (perlite and river sand). A total of 18 treatments, each with 20 cuttings, were repeated 3 times. See Table 1 for the factors and levels of cutting treatments.

Embodiment 2
[0050] The influence of embodiment 2 ear-picking methods on cutting rooting
[0051] 2.1 Ear picking method test
[0052] Tilia 7a, 15a, and 20a were selected as the mother plants for picking ears, and the semi-lignified shoots in the upper, middle, and lower parts of the crown were collected as cuttings, which were treated with 100mg / L ABT1 for 2 hours and then cuttages were placed in perlite. A total of 9 treatments, each with 20 cuttings, were repeated 3 times. See Table 7 for factors and levels of ear picking methods.
[0053] Table 7 Two-factor randomized block test
[0054]
[0055]
[0056] The cutting test was carried out in the full-light automatic spraying cutting greenhouse of Xinshan Seedling Professional Cooperative in Jilin City. The cutting bed was 30m long, 1.1m wide, and 25cm high, and the cutting substrate was 20cm deep. One day before the cutting, 1.25‰ carbendazim was used to disinfect the cutting substrate, and the cuttings were placed after water...
