Embodiment 1

[0027] A method for propagation of Japanese maple by cuttings, comprising the following steps:

[0028] Step a: Collect the tops of semi-lignified branches of the 3-year-old seedlings of Acer pentaphyllum and trim them to a length of 5-8 cm as cuttings. The tops of the branches are required to grow well and have no pests and diseases. Immediately after pruning, immerse the base of the cuttings in water , and spray the leaves with water.

[0029] Step b: remove the leaves below 3 cm from the base of the cuttings, keep the leaves on the upper part of the cuttings, and keep 2 to 3 nodes in the whole cuttings.

[0030] Step c: use perlite and peat with a volume ratio of 6:4 as a mixed matrix, put the mixed matrix into a 50-hole deepened plug with a plug cover after disinfection; the specific steps for the mixed matrix disinfection are: use 75% of the Spray the mixed matrix with a 500-fold solution of wettable chlorothalonil powder and mix evenly to ensure that the mixed matrix is...

Embodiment 2

[0034] A method for propagation of Japanese maple by cuttings, comprising the following steps:

[0035] Step a: Collect the tops of semi-lignified branches of the year-old tissue-cultured potted seedlings of Acer pentaphyllum and trim them to 5-8 cm as cuttings. The tops of the branches are required to grow well and be free from diseases and insect pests. Cuttings should be removed immediately after pruning Submerge the base in water and spray the leaves with water.

[0036] Step b: remove the leaves below 3 cm from the base of the cuttings, keep the leaves on the upper part of the cuttings, and keep 2 to 3 nodes in the whole cuttings.

[0037] Step c: use perlite and peat with a volume ratio of 6:4 as a mixed matrix, put the mixed matrix into a 50-hole deepened plug with a plug cover after disinfection; the specific steps for the mixed matrix disinfection are: use 75% of the Spray the mixed matrix with a 500-fold solution of wettable chlorothalonil powder and mix evenly to e...

Embodiment 3

[0041]A method for propagation of Japanese maple by cuttings, comprising the following steps:

[0042] Step a: Collect the middle and lower sections of semi-lignified branches of the year-old tissue-cultured potted seedlings of the 1-year-old Acer pentaphyllum and trim them to 5-8 cm as cuttings. The middle and lower sections of the branches are required to grow well and have no pests and diseases. After pruning, cut the cuttings immediately Submerge the base in water and spray the leaves with water.

[0043] Step b: remove the leaves below 3 cm from the base of the cuttings, keep the leaves on the upper part of the cuttings, and keep 2 to 3 nodes in the whole cuttings.

[0044] Step c: use perlite and peat with a volume ratio of 6:4 as a mixed matrix, put the mixed matrix into a 50-hole deepened plug with a plug cover after disinfection; the specific steps for the mixed matrix disinfection are: use 75% of the Spray the mixed matrix with a 500-fold solution of wettable chloro...

Abstract

The invention belongs to the technical field of plant cutting propagation and discloses an acer pentaphyllum cutting propagation method. The method includes steps: acquiring acer pentaphyllum branches, trimming into short branches in length of 5-8cm to serve as cuttings, trimming, soaking bases of the cuttings into water as soon as possible, and spraying clear water to wet leaves; preparing a mixed substrate from perlite and peat in a volume ratio of 6:4, disinfecting the mixed substrate, and adding into deepened trays with tray covers; soaking the bases of the cuttings in rooting liquid for 0.5h, inserting into the mixed substrate, and compacting immediately, wherein holes and the cuttings are in one-to-one correspondence; putting the deepened trays into a simple culture chamber, controlling the temperature at 22-25 DEG C, keeping humidity in the deepened tray to be 100% and illuminating intensity in a range of 700-1200lx, irrigating the cuttings and the nearby mixed substrate with 40ml of rooting liquid at a time interval of 3d, and totally irrigating for 3 times; 10d after cuttage, spraying a disinfectant once every other week until rooting of all cuttings is realized. Components of the rooting liquid are simple, and low cost, step simplicity, freeness of complexity and high cuttage rooting rate and survival rate are realized.

Description

technical field [0001] The invention belongs to the technical field of plant cutting propagation, and relates to a method for cutting propagation of Japanese maple. Background technique [0002] Acer pentaphyllum Diels is a deciduous tree belonging to the family Aceraceae, which can reach a height of 10m. It has palmate compound leaves and has 4-7 leaflets, usually 5 leaflets. It is a unique species in Sichuan, China. Due to its unique leaf shape and brilliant color, this plant is one of the most ornamental maple species in the world. It is as famous as Davidia involucrata, a well-known ornamental tree in Western horticultural circles. According to the IUCN endangered level standard (IUCN 1994), this species is already a critically endangered species. According to the literature, there are only more than 500 Acer syringae in the wild, belonging to 4 populations, and these populations are being affected by human grazing, logging and The serious threat of hydropower station c...
