Embodiment 1

[0024] A method for cultivating camellia oleifera saplings, comprising the following steps:

[0025] a. Dry the tea seeds from the natural cracking of the tea fruit, choose the plump, large, and pest-free seeds, soak the seeds with 100% thiophanate-methyl wettable powder mixed with 15 liters of water for 10 minutes, dry them in the shade, and store them in sand for later use ;

[0026] b. After the temperature stabilizes in early March, use clean sand, disinfect it and organize it into a sand bed with a height of 10 cm and flatten it; take out the seeds stored in the sand, densely sow a layer of seeds on the sand bed, and then cover with a 15 cm sand layer , and flatten, compress, and cover with a film;

[0027] c. In April, when the rootstock seedlings germinated from tea seeds were 8 cm in length, 3 cm in diameter and did not expose the sand layer, the rootstock seedlings were lifted out, the sand was cleaned, and 50% carbendazim wettable powder 700 Sterilize and sterilize...

Embodiment 2

[0040] A method for cultivating camellia oleifera saplings, comprising the following steps:

[0041]a. Dry the tea seeds that are naturally cracked and protruded from the tea fruit, choose the plump and large seeds that are free from diseases and insect pests, soak and disinfect the seeds with 100% thiophanate-methyl wettable powder mixed with 20 liters of water for 10 minutes, dry in the shade, store in sand for later use ;

[0042] b. After the temperature stabilized in the first ten days of March, clean sand was selected, and after disinfection, it was sorted into a sand bed with a height of 12 cm and flattened; the seeds stored in the sand were taken out, a layer of seeds was densely sown on the sand bed, and then covered with a 20 cm sand layer , and flatten, compress, and cover with a film;

[0043] c. In May, when the tea seed germinates and grows rootstock seedlings with a length of 12 cm and a diameter of 4 cm and the sand layer is exposed at the end, remove the root...

Embodiment 3

[0056] The difference between the cultivation method of the present embodiment Camellia oleifera sapling and embodiment 1 is following steps:

[0057] a. Dry the tea seeds that are naturally cracked and detached from the tea fruit, choose the seeds that are plump, large, and free from diseases and insect pests, soak and disinfect the seeds with 50% carbendazim wettable powder 700 times solution for 10 minutes, dry in the shade, and store in sand for later use;

[0058] The disease prevention and control measures of step 1 are: adopt forest management measures, improve ventilation and light transmission conditions, prevent Camellia oleifera soft rot, spray 50% carbendazim wettable powder 800 times of liquid control every 30 days; if Camellia oleifera root rot After the onset, remove the severely diseased plants, and use 1000 times of 50% tuzet wettable powder to irrigate the rhizomes to prevent and control Camellia oleifera root rot.

[0059] All the other features are the same...

Abstract

The invention discloses a cultivation method for camellia oleifera tree seedlings, and relates to the technical field of cultivation of nursery stocks. According to the cultivation method, the survival rate of grafted seedlings is greatly increased by selecting tea seeds, cultivating rootstock seedlings, selecting good clone scions, grafting the scions and the rootstock seedlings, planting the grafted seedlings into a light-medium non-woven cloth container, covering the container by a plastic thin film, building a covering shade above a seedbed, controlling the temperature and the humidity in the plastic thin film and preventing and treating plant diseases. The cultivation method disclosed by the invention is used for directly planting the grafted camellia oleifera seedlings into the light-medium non-woven cloth container for cultivation and the grafted camellia oleifera seedlings can grow fast without seedling recovering; the seedling qualification rate is about 60 percent; the seedlings are convenient to carry; the time and the labor are saved, and the labor can be saved by 50 percent; the qualified seedlings are not needed to be transplanted again, and the roots of the grafted seedlings are not injured; the grafted seedlings are planted in the light-medium non-woven cloth container, so that the survival rate is high, and the large-area afforesting survival rate is 93.7 percent.

Description

technical field [0001] The invention relates to the technical field of seedling cultivation, in particular to a method for cultivating camellia oleifera seedlings. Background technique [0002] Camellia oleifera, also known as tea fruit tree, camellia oleifera tree, and white flower camellia oleifera, is an evergreen shrub or small tree belonging to the genus Camellia in the family Theaceae. It is an important woody oil tree species in southern my country. Generally, it starts to bear fruit in 5 years, and enters the full fruit period in 10 years; the grafted seedlings start to bear fruit in 2 years, and enter the full fruit period in 5 years. Under good management conditions, the full fruit period can last for 40 to 50 years. The cultivation method of Camellia oleifera saplings that is usually adopted at present is to put the grafted seedlings of Camellia oleifera in the field for cultivation, and then move the grafted seedlings that have been cultivated in the field into li...
