Problems solved by technology

Acer palmatum is propagated by seed sowing, but the flowering cycle of Acer palmatum is long, the seeds need sand storage and other technical links, and the rapid popularization and application of new varieties such as famous and high-quality is limited to some extent; while grafting propagation needs to cultivate two-year-old or more palmatum rootstock, and then graft the required Acer palmatum variety scion on the rootstock, so it needs a longer seedling cultivation period; since Acer palmatum is a tree species that is difficult to root, the survival rate of cutting propagation is very low; in recent years, related Scholars have carried out tissue culture of Acer palmatum, such as Chinese patent CN101849506A discloses a method for rapid propagation of Acer palmatum through tissue culture, although this method overcomes the shortcomings of the traditional Acer palmatum breeding cycle is long, cutting propagation coefficient is low, etc. Factory production of maple seedlings, but the technical requirements for tissue culture are high, the operation is complicated, and the production cost is expensive

Embodiment 1

[0019] Example 1: A kind of high-altitude layering propagation method of Acer palmatum, it comprises the following steps:

[0020] S1. Mother tree selection: In May of each year, choose the Acer palmatum as the mother tree, which grows vigorously, is disease-free and pest-free;

[0021] S2. branch selection: select the branch that has been grown for 2 years on the mother tree, and the stem thickness is 0.7cm as the branch of the high-altitude plying bar;

[0022] S3. High-altitude layering: girdling is carried out at the middle and lower parts of selected branches, such as figure 1 As shown, the width of the girdling phloem is 1.6cm, and the length of the girdling phloem is 2 / 3 of the circumference of the branches at the circumcision place. Pay attention to scraping the cortex and cambium; Wrap the incision with toilet paper or absorbent cotton for hormone treatments such as figure 2 As shown, after hormone treatment for 1 day, take off the toilet paper or absorbent cotto...

Embodiment 2

[0025] Example 2: A kind of high-altitude layering propagation method of Acer palmatum, it comprises the following steps:

[0026] S1. Selection of mother tree: in August of each year, choose the Acer palmatum as the mother tree, which grows vigorously, is disease-free and has no pests;

[0027] S2. branch selection: select the branch that has been grown for 3 years on the mother tree, and the stem thickness is 1.0cm as the branch of the high-altitude plying bar;

[0028] S3. High-altitude layering: girdling is carried out at the middle and lower parts of selected branches, such as figure 1 As shown, the width of the girdling phloem is 2.4cm, and the length of the girdling phloem is 2 / 3 of the circumference of the branch at the circumcision place. Pay attention to scraping the cortex and cambium; Wrap the incision with toilet paper or absorbent cotton for hormone treatments such as figure 2 As shown, after hormone treatment for 2 days, take off the toilet paper or absorbe...

Embodiment 3

[0031] Example 3: A kind of high-altitude layering propagation method of Acer palmatum, it comprises the following steps:

[0032] S1. Mother tree selection: in June of each year, select Acer palmatum as the mother tree, which grows vigorously, is disease-free and pest-free;

[0033] S2. branch selection: select the branch that has grown for 2.5 years on the mother tree, and the stem thickness is 0.8cm as the branch of the high-altitude plying bar;

[0034] S3. High-altitude layering: girdling is carried out at the middle and lower parts of selected branches, such as figure 1 As shown, the width of the girdling phloem is 1.8cm, and the length of the girdling phloem is 2 / 3 of the circumference of the branches at the girdling place. Pay attention to scraping the cortex and cambium; Wrap the incision with toilet paper or absorbent cotton for hormone treatments such as figure 2As shown, after 1.5 days of hormone treatment, the toilet paper or absorbent cotton was removed, and...

Abstract

The invention discloses a Japanese maple air layering propagation method which includes selecting a seed tree, selecting branches, air layering, forming new trees, and transplanting new trees. The method has the advantages that the branches, grown 2-3 years, on a growing Japanese maple are used for air layering, allowing the branches to grow on the seed tree in a nutritious manner for 65-72 days, and forming a root system at the ringing cut; the branch rooting rate is 80%, and the transplanting survival rate can reach more than 78%; the air layering propagation method can keep the excellent hereditary features of the seed Japanese maple; the method is simple in technology, convenient to operate, low in cost, high in survival rate and important for Japanese maple seedling fast propagation.

Description

technical field [0001] The invention relates to a plant propagation technology method, in particular to the high-altitude layering propagation technology of Acer palmatum. Background technique [0002] Acer paimatum (Acer paimatum), also known as Yafeng, belongs to the genus Aceraceae, and is a valuable ornamental tree species in urban landscapes. It is native to the Yangtze River Basin in China, and is also distributed in Japan and the Korean Peninsula. my country is mainly distributed in the provinces of the Yangtze River Basin, and it mostly grows in forest margins or sparse forests of mountains and hills below 1200m above sea level. Acer palmatum is a deciduous small tree, about 8m high, with dark gray bark, purple or lavender green branches in the current year; light gray, purple or dark purple branches in perennial branches. Acer palmatum leaves opposite, 7-10 cm in diameter, truncate at base, deeply lobed palmately, with 5-9 lobes, usually 7-lobed, lobes ovate-oblo...
