Embodiment 1

[0032] A method for improving the seedling rate of vaccinium vaccinium seedlings, comprising the steps of:

[0033] (1) Soil preparation for bed: carefully prepare the ground and make a bed, the width of the bed is 110cm, the width of the trail is 60-70cm, and the height of the bed is ≥ 20cm;

[0034] (2) Adjust the pH: evenly spread sulfuric acid powder 130g / m on the bed surface before sowing 2 , It should be mixed evenly with the 5-6cm thick topsoil on the bed surface.

[0035] (3) Sowing: Sowing starts when the ground temperature at the depth of 5cm in the soil is stable at 10°C. The seeds will be treated with a plasma processor, the treatment dose is 1.2A, and the treatment is 3 times. The seed flow rate is 1.0kg / min. Mix and dilute the sand so that the seed sand is mixed evenly and loosely. The volume ratio of seeds and fine river sand is about 1:10, and the seeding rate is 20g / m 2 Spread evenly.

[0036] (4) Covering with soil and covering the reed curtain: with the s...

Embodiment 2

[0039] A method for improving the seedling rate of vaccinium vaccinium seedlings, comprising the steps of:

[0040] (1) Soil preparation for bed: carefully prepare the ground and make a bed, the width of the bed is 110cm, the width of the trail is 60-70cm, and the height of the bed is ≥ 20cm;

[0041] (2) Adjust the pH: before sowing, evenly spread sulfur powder 130g / m on the bed surface 2 , It should be mixed evenly with the 5-6cm thick topsoil on the bed surface.

[0042] (3) Sowing: Sowing starts when the ground temperature at the depth of 5cm in the soil is stable at 12°C. The seeds are treated with a plasma processor, the treatment dose is 2.0A, and the treatment is 3 times. The seed flow rate is 1.5kg / min. Uniform and loose, the volume ratio of seeds and fine river sand is about 1:10, and the seeding rate is 20g / m 2 Spread evenly.

[0043] (4) Covering with soil and covering the reed curtain: with the sowing and covering with soil, timely suppress and cover the reed c...

Embodiment 3

[0046] A method for improving the seedling rate of vaccinium vaccinium seedlings, comprising the steps of:

[0047](1) Soil preparation for bed: carefully prepare the ground and make a bed, the width of the bed is 110cm, the width of the trail is 60-70cm, and the height of the bed is ≥ 20cm;

[0048] (2) Adjust the pH: before sowing, 10 bed surfaces are evenly sprinkled with sulfur powder 150g / m 2 , It should be mixed evenly with the 5-6cm thick topsoil on the bed surface.

[0049] (3) Sowing: Sowing starts when the ground temperature at the depth of 5cm in the soil is stable at 14°C. The seeds are treated with a plasma processor, the treatment dose is 1.7A, and the treatment is 3 times. The flow rate of the seeds is 1.2kg / min, mixed with dry and fine river sand Dilute to achieve uniform and loose seed sand mixing, the volume ratio of seeds and fine river sand is about 1:10, and the seeding rate is 20g / m 2 Spread evenly.

[0050] (4) Covering with soil and covering the reed...

Abstract

The invention provides a method for improving seedling percentage of vaccinium uliginosum seedling culture. The method comprises the steps of soil preparation and seedbed preparation, PH adjustment, sowing, earthing and covering with a reed screen, and field management. Through adoption of the seedling culture method, the rate of emergence of vaccinium uliginosum and the uniformity of seedlings are improved remarkably. According to the technical scheme, soil PH is improved, air permeability of soil is improved, beneficial mycorrhizal fungi of the vaccinium uliginosum can propagate and grow well, and favorable environment is created for the growing of the vaccinium uliginosum seedlings, and the seedling percentage is improved. A cold-proof technology used in the method prevents the seedlings from being damaged by winter cold wind and spring physiologic drought, the method is easy to carry out, and the storing rate of surviving seedlings is greatly improved.

Description

technical field [0001] The invention relates to a method for breeding vaccinia seedlings, in particular to a method for increasing the seedling rate of vaccinia. Background technique [0002] Vaccinium uliginosum, also known as Dushi, Dianguo, etc., is an edible colored berry of the Ericaceae genus Vaccinium. Its fruit is dark blue, with a delicate taste and a pleasant fruity fragrance. People, making fruit wine, fruit vinegar, jam, fruit juice and the raw materials for extracting natural food coloring. Studies have shown that bilberry has anti-oxidation, anti-aging, anti-cancer, cardiovascular disease prevention, vision protection and other effects. It has excellent health care effects and has been designated as one of the five health foods by the International Food and Agriculture Organization. Its distribution is very narrow, and the number in Changbai Mountain is very rare, and a large population is distributed only in Changbai Mountain National Nature Reserve. The low...
