This study makes known that the progress of raising seedlings of Lonyan by cuttings.1.By using the Two-Bud-cutting, the root-growing rate and the growth condition are nearly as same as that of long cutting with several buds and a lot of cuttings being saved.2.The suitable xyloid content in the cutting is 17.73%to 19.04%and the colour of the cutting is light-green,dark-green or light-brown,accordingly.3.The Two-Bud-Cutting with a width of 2 cm should be done by KG-1 type cycle-peeling knife made by us.When the wound heals up and produces the white callus(about 15 days after peeling off),the cutting can be cut from the mother tree to raise seedling and two green leaves should be remained on each cutting.4.The cutting base should besoaked in 150 mg/kg IBA for about 5 minutes before cultivated.5.The suitable substrate for raising cuttings are made of 70%peat soil and 30%vermiculite powder.The seedling bed should be in the green house with the treatment of fine spray.The air temperature should be kept between 20~27 ℃ and the relative humidity should be above 85%.According to the method as mentioned above,the cutting begins to grow roots after 60days and the seedling survival rate reaches 85%to 90%.The period of raising seedlings by this way can be about one year shorter than that by graftage.
