Problems solved by technology

Camellia oleifera can take out shoots many times a year, mainly including spring shoots, summer shoots and autumn shoots, but the current production of bud seedlings grafting seedlings is mainly carried out in May to June, using spring shoots, and the utilization rate of autumn shoots is low , not only causes waste of spikes, but also because the seedlings need to be cultivated in a closed high-temperature and high-humidity environment at the initial stage of grafting, they are extremely susceptible to the influence of diseases and insect pests and reduce the survival rate
At present, there is no relevant report on the grafting of Camellia oleifera in winter and spring

Embodiment 1

[0026] 1. Rootstock cultivation

[0027] On October 26, 2011, the fruit of the common Camellia oleifera Cenruan family in the collection nursery of the excellent strains of Camellia oleifera in Guangxi Academy of Forestry was retrieved after fully ripening, dried in the shade after 2 days in the sun, and manually peeled out the seeds. The plump tea seeds are used as seeds. Soak the seeds in clean water for 2 hours, remove them and put them in 0.1% potassium permanganate solution for 20 minutes, take them out and rinse them with clean water.

[0028] In the awning, a 30cm high, 1m wide and 10m long geothermal Camellia oleifera winter and spring bud seedling cultivation bed is built with bricks on the ground. It is heated by a geothermal line. River sand, and then spread the rinsed seeds on the cultivation bed, lay 15kg of seeds per square meter of cultivation bed, cover with 10-12cm thick wet sand, pay attention to keep the river sand moist, carry out sand storage and germinat...

Embodiment 2

[0032] 1. Rootstock cultivation

[0033]On October 26, 2011, the fruit of the common Camellia oleifera Cenruan family in the collection nursery of the excellent strains of Camellia oleifera in Guangxi Academy of Forestry was taken back after being fully mature, dried in the shade after 1 day in the sun, manually peeled and removed the seeds, and put them in the trough in the shade shed. The lifting type seedling bed covered with film is set as the Camellia oleifera winter and spring bud seedling anvil cultivation bed. First, a layer of fresh medium-coarse river sand with a thickness of about 6 cm is laid on the bottom of the cultivation bed, and then the rinsed seeds are spread on the cultivation bed. Put 15kg of seeds on the rice cultivation bed, cover with 8cm thick wet sand, pay attention to keep the river sand moist, and carry out sand storage to accelerate germination. Disinfect the Camellia oleifera seeds with 0.1% potassium permanganate, spread the washed Camellia oleif...

Embodiment 3

[0037] At the end of October 2010, picked mature common camellia oleifera fruits from the collection garden of fine strains of Camellia oleifera of Guangxi Academy of Forestry, dried in the shade after 1 day in the sun, peeled the seeds, soaked them in clean water for 2 hours, then fished them out and added 0.1% high manganese Soak in potassium nitrate solution for 20 minutes to disinfect. Choose a leeward, sunny, and well-permeable open-air site to build a geothermal camellia winter-spring bud seedling cultivation bed, and carry out sand germination on November 5. First, a layer of fresh medium-coarse river sand about 9 cm thick is spread on the bottom of the germination bed, and then Spread the washed seeds on the ground, avoid overlapping the seeds as much as possible, and cover with 9-13cm thick wet sand, and finally cover a layer of film on the germination bed, and compact it with sand and stones around it. 34.20% of the seeds grew radicles after 30 days of sand storage a...

Abstract

The invention discloses an oil camellia bud seedling stock-grafting propagation method in winter and spring. The oil camellia bud seedling stock-grafting propagation method in winter and spring comprises processes such as stock cultivation, seedling growing bed preparation, seedling growing container preparation, grafting, grafted seedling planting, and seedling management. By heating a germination bed in winter and spring and utilizing the lifting-type seedling growing bed for growing seedlings, oil camellia bud seedling stock-grafting and grafted seedling cultivation are achieved in winter and spring, cultivation in an enclosed high-temperature and high-moisture environment is guaranteed for the initial stage of the oil camellia bud seedling stock-grafting, the survival rate reaches to 98.56%, average height in the same year reaches to 28.34 cm, and the ground diameter is 3.56 mm. Therefore, the survival rate of the grafted seedlings is increased, the grafted seedlings are capable of coming out of a nursery in the same year, the seedling cultivation circle is shortened, the using rate of cutting wood is increased, and the survival rate and seedling growing quality of oil camellia large-scale grafting are effectively improved.

Description

[0001] technical field [0002] The invention relates to a propagation method of camellia oleifera, in particular to a method for grafting and propagation of camellia oleifera in winter and spring. Background technique [0003] Camellia ( Camellia spp.) is the most productive oil-use species in the Theaceae family Camellia. Camellia oleifera in a broad sense refers to the tree species with high seed oil content in Camellia plants and a certain cultivation area. Camellia oleifera is originally produced and mainly planted in my country. Together with olive, oil palm and coconut, it is known as the world's four major woody oil plants. The current area of ​​camellia oleifera forests in the country is about 4 million hectares 2 , accounting for more than 80% of the cultivated area of ​​woody edible oil tree species in my country. The main product of camellia oleifera is camellia oil, which is a healthy edible oil promoted by the Food and Agriculture Organization of the United N...
