Problems solved by technology

However, in the actual operation of the seeding method, due to the influence of the planting environment, the germination rate of Magnolia magnolia seeds is not high, resulting in waste of seeds, and under normal sowing methods, the seed germination cycle is longer, which is not conducive to the growth of seedlings.

Embodiment 1

[0018] A method for breeding magnolia seedlings with high germination rate, high plant height, cold resistance and wind resistance, comprising the following steps:

[0019] S1: Seed collection. Collect the fruits of Magnolia magnolia tree in mid-September, and spread the fruits in a ventilated place to dry. The gathered fruits gradually crack, and the seeds are screened out, and the seeds are soaked in clear water at a temperature of 55°C for 4 hours. In the middle of the hour, take out the seeds and mix them with abrasives, the abrasives are a mixture of 5 parts of limestone, 3 parts of sand and 1 part of lime powder, wherein the particle size of the limestone is 2 mm, remove the red fleshy film attached to the seed coat, and use soda Scrub the oil on the seed coat with water, then rinse it with clean water, spread it in a ventilated place to dry, and recycle;

[0020] S2: Seedbed preparation, the seedbed matrix is ​​divided into every 667m 2 Apply 1000kg of decomposed organ...

Embodiment 2

[0025] A method for breeding magnolia seedlings with high germination rate, high plant height, cold resistance and wind resistance, comprising the following steps:

[0026] S1: Seed collection. Collect the fruits of Magnolia magnolia tree in mid-September, and spread the fruits in a ventilated place to dry. The gathered fruits gradually crack, and the seeds are screened out, and the seeds are soaked in clear water at a temperature of 60°C for 6 hours. In the middle of the hour, take out the seeds and mix them with abrasives, the abrasives are a mixture of 7 parts of limestone, 4 parts of sand and 2 parts of lime powder, wherein the particle size of limestone is 3 mm, remove the red fleshy film attached to the seed coat, and use soda Scrub the oil on the seed coat with water, then rinse it with clean water, spread it in a ventilated place to dry, and recycle;

Embodiment 3

[0032] A method for breeding magnolia seedlings with high germination rate, high plant height, cold resistance and wind resistance, comprising the following steps:

[0033] S1: Seed collection. Collect the fruits of Magnolia magnolia tree in mid-September, and spread the fruits in a ventilated place to dry. The gathered fruits gradually crack, and the seeds are screened out, and the seeds are soaked in clear water at a temperature of 65°C for 8 hours. In the middle of the hour, take out the seeds and mix and stir them with the friction agent, the friction agent is a mixture of 8 parts of limestone, 5 parts of sand and 3 parts of lime powder, wherein the particle size of the limestone is 4 mm, remove the red fleshy film attached to the seed coat, and use soda Scrub the oil on the seed coat with water, then rinse it with clean water, spread it in a ventilated place to dry, and recycle;

Abstract

The invention discloses a breeding method of southern magnolia nursery stocks high in germination rate, large in plant height, and resistant to coldness and wind. The breeding method comprises the following operation steps of 1, collection of seeds, 2, preparation of a seedbed; 3, germination of seeds; 4, sowing; 5, field management. By mixing the seeds with abrasive, fleshy membranes can be morequickly taken out of the seed coat surface, the internal structure of the seeds is not injured, and the entireness of the seeds is guaranteed; by spraying heteroauxin during germination accelerating,the germination speed of the seeds can be increased, and the breeding time is shortened; a medium of the seedbed is aired, germs and microorganisms can be killed, it is prevented that tender shoots ofthe seeds are damaged, and the seed germination rate is guaranteed; through topdressing in the seedling stage, the requirement of the growth of seedlings for nutrients is guaranteed, and the growth of the seedlings is accelerated.

Description

technical field [0001] The invention belongs to the technical field of nursery stock breeding, and in particular relates to a breeding method for magnolia seedlings with high plant height, cold resistance and wind resistance. Background technique [0002] Magnolia ， Alias: Western Magnolia, lotus Magnolia, a plant of the Magnoliaceae and Magnolia genus. Native to the Americas, North America, and the Yangtze River Basin in mainland China and the areas south of it. In the north, such as Beijing, Lanzhou and other places have introduced species. For viewing, the flowers contain aromatic oil. Because the flowers are very large and resemble lotus, it is also called "Lotus Magnolia". It can be used as medicine and road greening. The lotus magnolia tree has a majestic and majestic posture, broad leaves and thick shade, and lotus-like flowers with fragrant fragrance. It is a beautifying tree species, resistant to smoke and wind, and has strong resistance to toxic gases such as s...
