Problems solved by technology

Camellia cultivated in soil not only grows slowly, but also has a long childhood period. It takes 5-6 years or even longer from seed germination to plant flowering, resulting in a long production cycle of camellia potted flowers, and the high price of potted flowers makes it difficult to enter thousands of households. In addition, soil cultivation is easy to spread diseases and insect pests, pathogenic bacteria and soil protozoa are not easy to kill, and it is not conducive to export customs clearance, which seriously restricts the development of camellia industry
For this reason, many planting enterprises and farmers have discussed the soilless cultivation method of camellia potted flowers, and adopted grafting methods to shorten the childhood period of potted camellias. Suitable soilless cultivation management method with supporting substrate, and the cultivation of rootstock takes 1-2 years, and it takes 2-3 years or even longer to cultivate commercial potted flowers after grafting and survival

Embodiment 1

[0040] Embodiment 1: take the camellia variety ' Parkes ' as an example, the present invention is described further:

[0041] (1) Cutting propagation of seedlings

[0042]Install a high-pressure dense mist automatic spraying device and set a seedbed in a colorless and transparent plastic shed. The seedbed is paved with a substrate mixed with peat and perlite according to the volume ratio of peat: perlite is 2:1. At the end of June, Cut the semi-lignified branches of the current year's camellia female plants free of diseases and insect pests as cuttings, dip the base of the cuttings in a rooting agent containing 0.8% IBA and 5% thiophanate-methyl for 8-10 seconds, then air-dry them naturally, and then insert them into the seedbed matrix. Water thoroughly; the high-pressure dense mist automatic spray device comes with a probe for measuring relative air humidity, which can set the range of relative air humidity according to needs, and automatically start the spraying time and fre...

Embodiment 2

[0074] Embodiment 2 except that following measures are different, all the other measures are identical with embodiment 1.

[0075] (1) Cutting propagation of seedlings

[0076] At the beginning of July, cut off the semi-lignified branches of the female plant of the Camellia cultivar 'Liexiang' without diseases and insect pests as cuttings, and the rooting agent dipped in the base of the cuttings is a rooting agent containing 1.0% IBA and 5% thiophanate-methyl.

[0077] (2) upper basin

[0078] The soilless cultivation substrate in the 10*10cm seedling pot is made of peat and perlite mixed according to the volume ratio of peat: perlite is 2:1.

[0079] (3) Management after potting

[0080] ③Moisture management

[0081] C. From March to May of the next year after being potted, water 3 times a week at intervals, with an interval of 1 to 2 days between each watering;

[0082] D. From June to July of the next year after being potted, water twice a week at intervals, with an int...

Embodiment 3

[0090] Except that the camellia species selected for use is 'Huaxianzi', all the other cultivation measures are the same as in Example 1, and will not be repeated.

[0091] Above-mentioned each embodiment uses the synergistic effect of management such as soilless culture substrate of the present invention and fine light, temperature, water, fertilization, group pot, makes camellia grow rapidly, flower bud differentiation is smooth, plant growth is strong and strong, potted plant type is plump, and commodity value high. Calculated from the cutting at the end of June, the callus will start to form after 25 to 30 days of cutting, rooting will start after 60 days, and a root mass with a diameter of 1.5 to 3 cm will form at the base of the cutting seedlings after 80 to 100 days. Flower buds appear at the end of July of the next year after being potted, and potted in mid-November of the next year after being potted, and can be directly marketed as commercial potted flowers from Dece...

Abstract

The invention discloses a method for shortening a juvenile phase of potted commodity camellia flowers. The method comprises the steps of cutting propagation of seedlings, potting, management after potting, pot combination and management and disease and pest prevention and control. The method enables the camellia flowers to rapidly grow within a short period of time, a potted flower production period is shortened from 3-4 years of traditional grafting and cultivation to 18 months, the juvenile phase of the potted camellia flowers is remarkably shortened, the planting cost of the potted commodity camellia flowers is reduced, and meanwhile the shortcoming that pathogen spreading of cultivation soil and difficult killing of soil protozoons are adverse to export customs clearance is overcome.

Description

technical field [0001] The invention relates to the technical field of cultivation methods of woody ornamental plants, in particular to a method for shortening the juvenile period of camellia commercial potted flowers. Background technique [0002] Camellia, which belongs to the genus Camellia of the family Theaceae, is a famous traditional flower in my country and a world-renowned precious ornamental flower. Its bright and changeable flower colors, beautiful appearance, dense green leaves, and never withering through winter are deeply loved by people from all over the world. China has abundant camellia resources, and the development potential of the camellia industry is great. [0003] The potted flower production of Camellia has reached a relatively large scale at present, but most planting enterprises and farmers still use traditional soil cultivation to cultivate potted camellia. Camellia cultivated in soil not only grows slowly, but also has a long childhood period. I...
