Embodiment 1

[0019] (1) Cultivation on this stock: From October 1st to October 15th, collect the fruit of silver hazel from adult plants with strong growth and high seed setting rate as seeds, spread them flat in a sunny and ventilated place, and cover them with a layer of thin Hole nylon mesh to prevent the seeds from being shot and lost when the fruit cracks. After 4-5 days, collect the seeds, put them in a sealed bag, keep them dry, and store them in a refrigerator at 4°C. At the beginning of February next year, soak the stored seeds in normal temperature water. After 2 hours, screen the seeds, remove the light seeds floating on the water surface, select large and full seeds, and soak them in 400mg / L gibberellin for 24 hours. Sow evenly on a 20cm thick sand bed, the seeds should not overlap each other, and then cover with 5cm of clean river sand to keep the river sand moist, but not waterlogged. From April 20th to April 30th, the seedlings germinated on the sand bed were gradually trans...

Embodiment 2

[0023] Embodiment 2 Apply the method of the present invention to carry out the cultivation method of silver hazel main stock grafted seedling

[0024] With reference to the step operation of Example 1, in early February, 2009, the seeds of Silver Hazel were sown, and in late April, the sown seedlings were moved to the sandy soil nursery for maintenance and management. On October 28, 2011, perennial branches with flower buds were collected, cut into scions with 2-3 buds and 5-6cm long, and grafted by abdominal grafting. Survival survey was carried out after 30 days of grafting, and the survival rate reached 90.47 %, followed by fertilization, watering and pest control, flowering on March 25 of the following year, and investigation on April 26 showed normal fruiting.

Embodiment 3

[0025] Embodiment 3 Application method of the present invention carries out the cultivation method of silver hazel main stock grafted seedling

[0026] With reference to the step operation of Example 1, in early February, 2009, the seeds of Silver Hazel were sown, and in late April, the sown seedlings were moved to the sandy soil nursery for maintenance and management. On December 20, 2011, the perennial branches without flower buds were used as scions, cut into scions with 2-3 buds and 5-6cm long, and grafted in the form of abdominal grafting. Immediately after grafting, arch a transparent plastic film cover and carry out Keeping warm and moisturizing, the survival survey was carried out 30 days after grafting, and the survival rate reached 88.46%.

Abstract

The invention provides a cultivating method of Shaniodendron subaequalum stock grafted seedlings. The method comprises the following steps: collecting Shaniodendron subaequalum seeds for cultivation; selecting planted seedlings, which are reserved with beds, healthily and strongly grow and have ground diameters of not less than 0.5 cm, as stocks; collecting healthy and strong mature branches with no diseases and flower buds from mother Shaniodendron subaequalum trees; shearing the branches into 5-6 cm long scions with 2-3 muds; sealing and refrigerating the scions; grating the scions by using a side grafting method; sealing and moisturizing the grafted parts by using film strips; and preventing rainwater from entering grafting incisions. The cultivating method of the Shaniodendron subaequalum stock grafted seedlings, provided by the invention, has the advantages of simplicity in operation and high grafting survival rate; meanwhile, the juvenile phase of the Shaniodendron subaequalum is shortened and the Shaniodendron subaequalum can come into flowers in advance, so that the problem that planted Shaniodendron subaequalum seedling plants grow up with too long time is solved; the scions with flower muds can come into flowers in the next year, so that the problem that the planted Shaniodendron subaequalum seedlings grow up with too long time is solved; the endangered state of wild Shaniodendron subaequalum plants is eased; and the bred seedlings have both flowering and foliage characteristics; therefore, the cultivating method of the Shaniodendron subaequalum stock grafted seedlings, provided by the invention, can be widely used for landscaping.

Description

technical field [0001] The invention belongs to the field of plant grafting methods, in particular to a method for cultivating grafted seedlings of silver hazel root stock. Background technique [0002] Silver hazel ( Shaniodendron subaequale ) belongs to the family Hamamelidaceae and the genus Silver Hazel. It is an ancient relict plant of the Tertiary Period. At present, there are only a few plants of Silver Hazel in Anji City, Zhejiang Province, Yixing City, Jiangsu Province, Shucheng County, and Jixi County, Anhui Province. In 1999, silver hazel was included in the national list of rare and endangered plants. [0003] The crown of silver hazel is open, and the leaves turn red, yellow and purple in autumn. The flower shape is peculiar, the flowers are silvery, and the color is magnificent. It is a precious and excellent greening tree species that combines flower viewing and autumn foliage viewing. The growth rate is slow, the wood is very hard, the grain is straight, t...
