Embodiment 1

[0023] Example 1: The method for propagation of Acer palmatum Qinglong twig cuttings comprises the following steps:

[0024] S1. Cutting time: every April;

[0025] S2. Cutting substrate and disinfection: the cutting substrate of Acer palmatum Qinglong is a mixed substrate of perlite and humus, and the weight ratio of perlite and humus is 3:1; before cutting, use 80% wettability Spray 800 times of carbendazim powder on the cutting substrate to ensure that the substrate is thoroughly watered and covered with plastic film for 2 days before use; before cutting, it is necessary to rinse the substrate twice with clean water to prevent too much disinfectant from poisoning the cuttings;

[0026] S3. Ear picking: Ear picking is carried out on cloudy days or when the dew is not dry in the morning. Select a vigorously growing Acer palmatum green dragon mother tree, and use scissors to cut semi-lignified branches with a thickness of 0.3cm in the current year as spikes. The...

Embodiment 2

[0033] Example 2: The method for propagation of Acer palmatum Qinglong twig cuttings comprises the following steps:

[0034] S1. Cutting time: August every year;

[0035] S2. Cutting substrate and disinfection: the cutting substrate of Acer palmatum Qinglong is a mixed substrate of perlite and humus, and the weight ratio of perlite and humus is 5:1; before cutting, use 80% wettability Spray the cutting substrate with carbendazim powder 1000 times to ensure that the substrate is thoroughly watered and covered with plastic film for 3 days before use; before cutting, it is necessary to rinse the substrate with water 3 times to prevent excessive disinfectant from poisoning the cuttings;

[0036] S3. Ear picking: Ear picking is carried out on cloudy days or when the dew is not dry in the morning. Select a vigorously growing Acer palmatum green dragon mother tree, and use scissors to cut semi-lignified branches with a thickness of 0.5cm in the current year as spikes. ...

Embodiment 3

[0043] Example 3: The method for propagation of Acer palmatum Qinglong twig cuttings comprises the following steps:

[0044] S1. Cutting time: May every year;

[0045] S2. Cutting substrate and disinfection: the cutting substrate of Acer palmatum Qinglong is a mixed substrate of perlite and humus, and the weight ratio of perlite and humus is 4.3:1; before cutting, use 80% wettability Spray the cutting substrate with carbendazim powder 900 times to ensure that the substrate is thoroughly watered and covered with plastic film for 2.5 days before use; before cutting, it is necessary to rinse the substrate with clean water 3 times to prevent too much disinfectant from poisoning the cuttings ;

[0046] S3. Ear picking: Ear picking is carried out on cloudy days or when the dew is not dry in the morning. Select a vigorously growing Acer palmatum green dragon mother tree, and use scissors to cut semi-lignified branches with a thickness of 0.4cm in the current year as sp...

Abstract

The invention discloses an acer palmatum biondia heriyi twig cuttage propagation method. The method includes the following steps: S1, performing cuttage in April to August each year; S2, preparing a cuttage medium, and using carbendazim to spray the cuttage medium for sterilizing, wherein the cuttage medium is obtained by mixing perlite and humus; S3, collecting spikes, namely selecting annual semi-lignified branches of 0.3-0.6cm in thickness; S4, preparing a cutting; S5, sterilizing the cutting, namely using carbendazim to soak two ends of the cutting; S6, performing hormone treatment, namely soaking a base portion of the cutting in an IBA solution; S7, performing cuttage, namely inserting the cutting into the medium; S8, managing after cuttage; S9, transplanting. By the method, cuttage rooting rate reaches more than 80%, and transplanting survival rate can reach 90%. The method has the advantages of capability of maintain excellent characteristics of a mother plant, high propagation speed, high survival rate, simplicity in operation and high practicability, and has important application value in asexual propagation production of excellent seedlings of biondia heriyi.

Description

technical field [0001] The invention relates to a method for asexual propagation of plants, in particular to a method for cutting and propagating twigs of Acer palmatum and green dragon. 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, l...
