Problems solved by technology

[0003] Due to the relatively short introduction time of Siberian Sorbus, there is no systematic successful technology for sowing and seedlings to learn from, which often results in the phenomenon of no seedlings and lack of seedlings in sowing and raising seedlings. In terms of production, it is urgent to study the techno

Embodiment 1

[0030] Siberian Rowan Seeds Break dormancy and sow with refrigerator sand stratification as described:

[0031] (1) Seed treatment

[0032] Seed collection: In mid-October, the fruit was collected from the 4-year-old Siberian rowan seedling Youshu.

[0033] Picking seeds: In the above seed removal treatment, the freshly harvested fruits are hard and difficult to pick seeds. They can be placed in a ventilated place indoors and outdoors for 7-10 days, and the pulp can be processed after it becomes soft. Knead the pulp in a container or roll poplar and pine cork sticks on the rubber to form a paste, then put it in a 1mm sieve, rinse with tap water, wash off the pulp, and leave the seeds and peel in the sieve, finally The peel and seeds are drained of water, placed in a cool place to air-dry, and the peel is discarded. The characteristic water content of the seeds is 20% to 30%.

[0034] Seed storage: store the Siberian rowan seeds with a moisture content of 20% to 30% in a plas...

Embodiment 2

[0039] The described dormancy breaking and seeding techniques below the permafrost:

[0040] (1) Seed treatment

[0041] Seed collection: In mid-October, the fruit was collected from the 4-year-old Siberian rowan seedling Youshu.

[0042] Picking seeds: In the above seed removal treatment, the freshly harvested fruits are hard and difficult to pick seeds. They can be placed in a ventilated place indoors and outdoors for 7-10 days, and the pulp can be processed after it becomes soft. Knead the pulp in a container or roll poplar and pine cork sticks on the rubber to form a paste, then put it in a 1mm sieve, rinse with tap water, wash off the pulp, and leave the seeds and peel in the sieve, finally The peel and seeds are drained of water, placed in a cool place to air-dry, and the peel is discarded. The characteristic water content of the seeds is 20% to 30%.

[0043] Seed storage: store the Siberian rowan seeds with a moisture content of 20% to 30% in a plastic bag in a refrig...

Embodiment 3

[0050] The described technique of breaking seed dormancy and sowing with white plastic film covering in autumn:

[0051] (1) Seed treatment

[0052] Seed collection: In mid-October, the fruit was collected from the seedlings of the 4-year-old Siberian Sorbus excellent tree.

[0053] Picking seeds: In the above seed removal treatment, the freshly harvested fruits are hard and difficult to pick seeds. They can be placed in a ventilated place indoors and outdoors for 7-10 days, and the pulp can be processed after it becomes soft. Knead the pulp in a container or roll poplar and pine cork sticks on the rubber to form a paste, then put it in a 1mm sieve, rinse with tap water, wash off the pulp, and leave the seeds and peel in the sieve, finally The peel and seeds are drained of water, placed in a cool place to air-dry, and the peel is discarded. The characteristic water content of the seeds is 20% to 30%.

Abstract

The invention relates to an introduction, seedling-expanding and propagation technology of a precious and superior tree species, in particular to a method for breaking dormancy and sowing Sorbus sibirica seeds. The method comprises the steps of 1) collecting superior tree Sorbus sibirica fruits, processing, removing fruit pulp, cleaning, drying in the air, leading the water content of the seeds to be 20%-30%, and carrying out cold preservation at the temperature of 1-3 DEG C for standby; and 2) breaking the dormancy and sowing the seeds: breaking the dormancy of the seeds, sowing and propagating seedlings, and keeping the water content of the soil after the sowing at 18-23%. The method can obviously obtain better seedling raising effect, the test result shows that the germination rate of the seeds after breaking the dormancy can be more than 90%, the germination of the seeds is trim, the seedling emergence rate can be more than 85%, the phenomena of non-emergence of the seedlings or uneven seedlings of natural seeding or conventional sowing, in the year, the highest Sorbus sibirica seedling is 71cm, the average height of the seedlings is 40.78cm, the largest basal diameter is 1.18cm, the average basal diameter is 0.82cm, and the seedling raising effect is good.

Description

technical field [0001] The invention relates to a technique for introducing and expanding seedling propagation of precious tree species, specifically a method for breaking dormancy and sowing Siberian rowan seeds. Background technique [0002] Siberian rowan sorbus sibirica is the latest precious economic and ornamental tree species introduced from Russia. It is a subarbor tree with a tree height of 15-20m. As an ornamental cultivation, the tree height is generally 5-8m, the fruit diameter is 0.7-1.5cm, and the thousand-grain weight of dry seeds is 2.68g. Odd pinnate compound leaves, white flowers, red fruit, red fruit does not fall off in winter, adding unique ornamental value to snowy winter. [0003] Due to the relatively short introduction time of Siberian Sorbus, there is no systematic successful technology for sowing and seedlings to learn from, which often results in the phenomenon of no seedlings and lack of seedlings in sowing and raising seedlings. In terms of pro...
