Problems solved by technology

[0003] The existing cutting propagation methods of Acer safflower mainly adopt hard branch cutting, semi-lignified cutting and tender branch cutting. Among them, the hard branch cutting method is simple and easy to survive, but the rooting is slow and the differentiation performance is poor, so it is difficult to form a standard landscape tender branch cutting. Although the rooting is fast and the differentiation ability is very strong, the cutting seedlings are poor in stress resistance, difficult to manage after survival, and the plants grow slowly; semi-lignified cuttings have the best properties and strong plants; but the semi-lignified cutting methods are currently Immature, difficult to manage cuttings, poor resistance to infection, low survival rate, poor cold resistance, short color leaf period

Embodiment 1

[0030] Embodiment 1, a kind of semi-lignified shoot cutting method of Acer safflower, comprises the following steps:

[0031] 1. Material preparation

[0032] This experiment was carried out in the experimental nursery of Qingzhou Deli Agriculture and Forestry Technology Co., Ltd.;

[0033] In June, the semi-lignified "October Brilliant" shoots that grew vigorously, with full buds, and were basically the same in growth and thickness were selected as cuttings.

[0034] The thickness of the cuttings is 0.45 cm. Cut into sections, each section is 6 cm long, and keep 1 leaf.

[0035] 2. Treatment of cuttings

[0036] Carry out incision processing on the cuttings, wherein, the upper incision is about 1.2 to 1.8 cm away from the upper bud, and the lower incision is obliquely cut;

[0037] After the cuttings are cut, use 50% carbendazim wettable powder 500 times solution to soak the cuttings from the bottom to 1cm for 15 minutes, and then disinfect them for later use.

[0038] 3...

Embodiment 2

[0050] The experiment of the influence of the selected cuttings on the rooting rate of embodiment 2

[0051] Carry out cutting seedling raising according to the method of embodiment 1, only change the thickness and the length of semi-lignified shoot cuttings selected in step 1 material preparation and carry out embodiment 2~4; See table 1 for details:

[0052] Thickness and length of semi-lignified shoot cuttings selected in table 1 material preparation

[0053]

[0054] Investigate the cutting rooting situation of embodiment 1~4 after cuttingtage 50d, rooting rate (%)=cutting root number / cutting total number×100%;

[0055] The survey results are shown in Table 2;

[0056] The rooting rate of table 2 cuttings

[0057]

[0058] Investigation result shows, the rooting rate of embodiment 2, 3 is obviously higher, is preferred embodiment; The thickness of semi-lignified new shoot cuttings selected in step 1 material preparation is preferably 0.5~0.55cm, and length is prefe...

Embodiment 5

[0059] Example 5 Effects of different cutting substrates on the survival rate of Acer safflower

[0060] Carry out cutting seedling raising according to the method of embodiment 1, only change the cutting matrix in step 4 cutting, carry out embodiment 5~8; See table 3 for details;

[0061] Table 3 Cutting substrates used

[0062]

[0063] 80 days after cutting, investigate the survival of each cutting seedling, survival rate (%)=survival number of cuttings / total number of cuttings×100%; see Table 4 for details:

[0064] Table 4 Survival rate of cuttings

[0065] Example 5 Example 6 Example 7 Example 8 Survival rate % 85.5% 90.2 95.7 80.5%

[0066] The survey results show that the survival rate of the cuttings in Example 7 is significantly higher, and the cutting substrate in the cuttings is preferably a mixed substrate of river sand, vermiculite, and pine pollen at a volume ratio of 1:1:0.2.

Abstract

The invention provides a semi-lignified acer rubrum shoot cuttage method which comprises the steps of material preparation, a cutting processing, preprocessing before cuttage, cuttage, cuttage postprocessing, initial management and seedling management. In material preparation, the thickness of semi-lignified shoot cuttings is 0.45-0.65 cm. Cutting is performed to form sections, the length of each section is 6-12 cm, and one leaf is retained. Full-automatic atomizing cuttage is adopted, the relative air humidity in a greenhouse is 75%-90%, the temperature is 20-35 DEG C, and a sun-shading net with the double-layer coverage rate of 50% is laid outside the greenhouse. The cuttage depth is 3 cm, and the spacing between cutting seedling plants is 40 cm * 40 CM. After acer rubrum cuttage, the liquid which is 500 times of the amount of 50% carbendazim is used for sterilizing the greenhouse one time every two weeks. Compared with a conventional semi-lignified cuttage method, the seedling raising survival rate is improved by 26.9% and is up to 99.4% by adopting the semi-lignified acer rubrum shoot cuttage method.

Description

technical field [0001] The invention relates to a method for breeding Acer safflower, in particular to a method for cutting semi-lignified new shoots of Acer safflower, and belongs to the technical field of plant breeding. Background technique [0002] Red Acer is a deciduous tree belonging to the family Aceraceae. The tree is tall and upright. The tree shape is upright and upward, the crown is oval or round, and it opens gracefully. The old bark is rough, dark gray, scaly or wrinkled. New bark smooth, light gray. Branchlets are smooth, lenticeled, usually green, often turning red in winter. Single leaves opposite, palmately 3-5 lobed. Flowers are red, dense clusters, a small part of yellowish, flowers first and then leaves. The flowering period is April. The fruit is a samara, mostly reddish, turning brown when ripe. Likes moist environment and well-drained slightly acidic soil. Because of its eye-catching autumn colors and neat tree crowns, it is widely used in pa...
