Cutting propagation technology of cinnamomum japonicum of cold-resistant fine variety

The invention relates to a cutting propagation technology of cinnamomum japonicum of a cold-resistant fine variety, in particular to a cutting propagation method of an evergreen broadleaved tree cinnamomum japonicum of the cold-resistant fine variety, which belongs to the technical field of artificial plant propagation. The cutting propagation method comprises the following steps: an automatic spraying cutting tank is constructed; a cutting matrix is mixture of peat soil to pearlite of 1 to 1 (volume ratio), and the thickness is 10 to 12 cm; the length of a pruned cutting shoot is 10 to 12 cm, 3 to 4 leaves are left, and 4-D mixed liquor of 2000 ppm NAA + 500 ppm2 is used to perform the rapid dipping treatment to a cutting shoot base of 0 to 4 cm for 3 to 5 seconds before cutting; the cutting depth is 3 to 4 cm; after cutting, a watering can is used to water fully to ensure the cutting shoot is contacted with the matrix closely; the cutting shoot is cultured in a full exposure condition, and the automatic water spraying is performed according to the weather condition; when cutting seedlings are transplanted, slight cutting matrix is accompanied at the cutting root of the cuttingseedlings, thereby improving the transplanting survival percent. The cutting propagation method can ensure good features of the cinnamomum japonicum of the cold-resistant fine variety, and has simpleand feasible method and high propagation survival percent, thereby providing the nursling guarantee for the large-scale popularization and application of the cinnamomum japonicum of the cold-resistantfine variety.
