Abstract

The invention discloses a cutting propagation method of Litsea coreana trees. The cutting propagation method comprises the following steps of (1) selecting a suitable cutting land and preparing the cutting land; (2) selecting semiligneous branches, pruning the branches to retain 2cm-4cm lengths, and retaining 0.5-1.5 pieces of leaves on each branch; (3) cutting the branches subjected to pruning onto ridges according to line spacing of 4cm-6cm and row spacing of 2cm-3cm; (4) setting up an arch shed, covering the arch shed with sunshade nets and keeping the shading coefficient in the sheds to range from 95 percent to 98 percent; (5) keeping the soil wet after cutting, and spraying root growth liquid and nutrients again; (6) performing illumination training after cutting for 370-380 days, pulling open the sunshade nets at the two ends of the arch shed firstly, and then puling open all the sunshade nets after 2-4 days to perform full exposure training. The cutting propagation method of the Litsea coreana trees is low in cost, high in survival rate and free of limit of environmental climate.

Description

technical field [0001] The invention relates to the field of plant cultivation methods, in particular to a cutting propagation method of eagle tea tree. Background technique [0002] Eagle tea is a woody plant of Lauraceae, which is called Eagle tea tree in "Sichuan Wild Economic Flora". It is an evergreen tree with alternate leaves, thick leaves and dark green color. This kind of tree spreads all over the mountainous areas of Sichuan, and the growth altitude requirement is relatively high. It is more common in Ya'an, Shifang, etc. After the young branches and leaves are harvested and dried, it can be used as tea. The local people call it Eagle tea, also known as Laoyin tea. , Laolin tea (Leshan Emei area), especially in the rural areas of Sichuan, there is a habit of self-collecting and self-drinking eagle tea. Moreover, eagle tea contains a lot of aromatic oils and polyphenols. It is more fragrant when brewed, with a thick taste, first astringent and then sweet. There a...
