Problems solved by technology

If the cutting is carried out in winter, it coincides with the flowering period. In order to prevent flowering from consuming nutrients, remove all the buds and cut them on the hotbed; if the buds are not removed to ensure normal flowering, the survival rate of Daphne Phnom Penh is low
[0004] According to the existing literature, Daphne Phnom Penh is a fleshy root, and the humus soil is the most beneficial for its growth. The humus soil is loose and fertile, permeable and breathable, and has a strong ability to retain fertilizer and moisture. Use it with 30% fine sand as the cultivation soil , the growth of the seedlings is very good, and there are also records of using pond mud as the substrate, but the above-mentioned substrates are generally the substrates used for spring and autumn cuttings, and there are no relevant records for the substrates used in winter
[0005] Based on the above research, the cutting method of normal flowering and high survival rate of daphne daphne during the winter off-season cutting during the flowering period of Phnom Penh is not involved in the prior art

Embodiment 1

[0042]Using the anti-virus seedlings of Phnom Penh daphne as the test material, in the winter greenhouse, one week before the cutting, put the perlite sterilized by potassium permanganate after exposure to the sun into the seedbed with 20cm high sand and a layer of sunshade net, and spray it per square meter 2L 400 times carbendazim solution;

[0043] On January 20th, 1-year-old semi-lignified branches with buds were collected from Phnom Penh Daphne mother tree as cuttings. The cuttings were left with 4 leaves and 3 buds. Dip them in 200mg / L IBA hormone solution for 10 seconds at a medium speed, and cut them immediately. The cutting depth is about 4cm. The cutting density is 5cm×5cm;

[0044] After cutting, spray 50 times carbendazim solution once every 2 days in the morning and evening, each spraying volume is 1L / m 2 .

[0045] After one month of cutting, the survey rooting rate reached more than 85%, 6 adventitious roots of cuttings, root length 5cm, such as figure 1 As s...

Embodiment 2

[0047] Using the anti-virus seedlings of Phnom Penh daphne as the test material, in the winter greenhouse, one week before the cutting, put the perlite sterilized by potassium permanganate after exposure to the sun into the seedbed with 20cm high sand and a layer of sunshade net, and spray it per square meter 2L 400 times carbendazim solution;

[0048] On January 20th, 1-year-old semi-lignified branches with buds were collected from Phnom Penh daphne tree as cuttings. The cuttings were left with 4 leaves and 2 buds, dipped in 100mg / L IBA hormone solution for 5 seconds at medium speed, and cut immediately. The cutting depth was about 4cm. The cutting density is 4cm×6cm;

[0049] After cutting, spray 50 times carbendazim solution once every 2 days in the morning and evening, each spraying volume is 1L / m 2 .

[0050] One month after the cutting, the rooting rate was over 85%. There were 6 adventitious roots on the cuttings with a root length of 5 cm. The flower buds bloomed nor...

Embodiment 3

[0052] Using the commercially available 3-year-old Daphne Phnom Penh as the test material, put the perlite sterilized by potassium permanganate after exposure to the sun into the seedbed with 20cm high sand and a layer of sunshade net in the winter greenhouse, one week before cutting, and spray each square meter. Apply 2L 400 times carbendazim solution;

[0053] On January 20th, 1-year-old semi-lignified branches with buds were collected from Phnom Penh daphne tree as cuttings. The cuttings were left with 4 leaves and 2 buds, dipped in 300mg / L IBA hormone solution for 15 seconds at medium speed, and cut immediately. The cutting depth was about 4cm. The cutting density is 6cm×4cm;

[0054] After cutting, spray 50 times carbendazim solution once every 2 days in the morning and evening, each spraying volume is 1L / m 2 .

[0055] One month after the cutting, the rooting rate was over 85%. There were 6 adventitious roots on the cuttings with a root length of 5 cm. The flower buds ...

Abstract

The invention provides a daphone-odora-varmargmata flowering-period winter cutting method, and belongs to the field of woody-plant-flower vegetative propagation methods. The method includes the following steps that 1) annual semi-lignified branches with buds are selected as cuttings in a winter greenhouse; 2) the cuttings obtained in the step 1) are quickly dipped in an IBA hormone solution for 5s to 15 s; 3) the cuttings after being quickly dipped in the step 2) are inserted into cutting media of seedbeds; 4) after cutting, a carbendazim solution is sprayed one time every 1 d to 3 d morningand evening. In the daphone-odora-varmargmata flowering-period winter cutting method, in one month after cutting, the rooting rate is surveyed and can be 85% or above, 1-8 adventitious roots are subjected to cutting, and the root length is about 5 cm; the cuttings with the buds can also normally bloom, cutting seedlings are thick in leaf, golden edges are wide, and the ornamental value of the cutting seedlings can be guaranteed; after cutting is survived, the seedling rate can be 80% or above, and the survival rate of pot plants is 95% or above.

Description

technical field [0001] The invention belongs to the field of asexual reproduction methods of woody plants and flowers, and in particular relates to a winter cutting method of Phnom Penh daphne daphne flowering period. Background technique [0002] Daphne Phnom Penh is the city flower of Nanchang, and it is also a kind of New Year's Eve flower. The flowers are lavender and have a strong fragrance. The flowering period is from January to March, which coincides with the Spring Festival. The favorite, the market prospect is broad. [0003] Daphne Phnom Penh blooms but does not set seeds. It is usually propagated by cuttings. It is advisable to carry out around the ear seed or the autumnal equinox. When choosing cuttings in summer, the general method of cutting with water is to insert 1 / 3 of the cuttings into the water, straighten and fix them, and keep the water volume constant. Roots will survive within one month, and the rooting rate is almost 100%. If the cutting is carried...
