Problems solved by technology

[0003] At present, the cultivation of Photinia fragrans is mostly propagated by seeds and divisions. However, due to the long seedling time and low survival rate, the growth of Photinia frondosa is slow in the later stage, the growth rate is not easy to control, and the disease resistance is poor.

Embodiment 1

[0019] A seedling raising method of Photinia fragrans, specifically comprising the following steps:

[0020] a. Select mature and complete seeds, put the seeds into the mass fraction of 0.2% copper sulfate solution and soak for 1-2h,

[0021] b. Take out the seeds, put them in the sun to dry for 2-3 hours, then put them into the ABT rooting agent solution with a mass fraction of 0.018% and soak them for 10-12 hours;

[0022] c. After taking it out, put the seeds in a matrix culture tray with a hole diameter of 6-8mm and a depth of 10-12mm, with 2-3 seeds per hole, the air humidity is 60-65%, and the ambient temperature is 25-28°C. After the seeds are placed in the cultivation tray, sprinkle a layer of 1-2cm straw powder and cover with a plastic film. After the seeds germinate, remove the plastic film and spray the growth-promoting liquid once a day. When the first true leaf grows, spray it every day. 2 growth-promoting liquids, the air humidity is controlled at 75-77%, the am...

Embodiment 2

[0031] The difference between Example 2 and Example 1 is that the growth-promoting liquid and the weight parts of the raw materials in the matrix are different, and the others are the same.

[0032] The growth-promoting liquid is composed of the following raw materials in total parts: 3 parts of calcium nitrate, 2 parts of ammonium dihydrogen phosphate, 5 parts of magnesium sulfate heptahydrate, 6 parts of peel powder, 1 part of probiotics, indole butyric acid 1 part, 160 parts of water.

[0033] The matrix is ​​composed of the following raw materials in parts by weight: 5 parts of dead leaves, 2 parts of vermiculite, 2 parts of perlite, 1.5 parts of crystal mud, 11 parts of calcium nitrate, 2 parts of zinc sulfate, 6 parts of potassium dihydrogen phosphate, 4 parts of magnesium sulfate, 2 parts of ammonium sulfate, 3 parts of EM bacteria.

Embodiment 3

[0035] The difference between Example 3 and Example 1 is that the weight parts of the raw materials in the growth-promoting liquid and the matrix are different, and the others are the same.

[0036] The growth-promoting liquid is composed of the following raw materials in total parts: 5 parts of calcium nitrate, 1 part of ammonium dihydrogen phosphate, 6 parts of magnesium sulfate heptahydrate, 7 parts of peel powder, 1 part of probiotics, indole butyric acid 2 parts, 160 parts of water.

[0037] The matrix is ​​made up of the following raw materials in parts by weight: 5 parts of dead leaves, 3 parts of vermiculite, 2.5 parts of perlite, 1.3 parts of crystal mud, 11 parts of calcium nitrate, 2 parts of zinc sulfate, 6 parts of potassium dihydrogen phosphate, 4 parts of magnesium sulfate, 3 parts of ammonium sulfate, 4 parts of EM bacteria.

Abstract

The invention discloses a photinia fraseri seedling culture method. Seed pregermination and seedling culture are performed to obtain a plant, and the plant is transplanted before final singling; in the pregermination process, the germination and growth conditions are strictly controlled, the seed germination is promoted by a rooting agent solution, and the seed pregermination time is greatly shortened; and in the seedling culture process, the seeding culture is performed using a growth promoting solution so that the seedlings grow fast and uniformly. The method disclosed by the invention is simple, realizes low seedling culture cost and short seedling culture period, enhances the disease resistance of photinia fraseri, realizes a transplanting survival rate of more than or equal to 96% and facilitates practical promotion.

Description

technical field [0001] The invention relates to the field of plant planting, in particular to a method for raising seedlings of Photinia fruticosa. Background technique [0002] Photinia rosacea is an evergreen shrub of the genus Photinia in the family Rosaceae, also known as Millennium Red or Flame Red. Photinia is bred in Fraser Nursery in Alabama, USA. It is a hybrid of Photinia and Photinia glabra. It is named for its bright red shoots and leaves. Introduced from the Netherlands in 1995, it has high ornamental value. Photinia fragrans is a close relative of wild chrysanthemum, a herb of the genus Chrysanthemum in the family Asteraceae. It is an excellent ornamental ground cover plant, and has a wide market prospect in landscaping applications. [0003] At present, the cultivation of Photinia fragrans is mostly propagated by seeds and divisions. However, due to the long seedling time and low survival rate, Photinia frondosa grows slowly in the later stage, its growth is...
