Problems solved by technology

[0002] Guangyulan has strong resistance to smoke and sulfur dioxide gas, less pests and diseases, deep and wide root system, and strong wind resistance. Especially the seedlings have tall and straight trunks, majestic trees, and strong adaptability. They are commonly used greening trees and are loved by people; Magnolia magnolia is widely planted in my country. At present, there are three main seedling methods: sowing, grafting and layering. The workload of seed sowing and seedling cultivation is small, and it is not limited by seasons. However, the seeds need to be stored in sand and soaked to accelerate germination. The time is as long as 5 to 6 months. Moreover, the germination rate can only reach about 85%, which obviously reduces the seedling efficiency of Magnolia magnolia

Embodiment 1

[0018] A treatment method for improving the germination rate of Magnolia magnolia seeds, comprising the following steps:

[0019] (1) Soaking: Select mature, plump, and complete Magnolia magnolia seeds, soak them in a compound enzyme solution with a mass concentration of 0.02% for 2 to 3 hours, destroy the seed coat structure, accelerate the softening of the seed coat, and initially break the seed dormancy , to accelerate seed germination, to soak the seeds; the compound enzyme is composed of the following enzyme preparations in parts by weight: ligninase 17, cellulase 13, hemicellulase 7, lipase 4;

[0020] (2) Freezing: Put the soaked seeds in the refrigerator and freeze them at -10°C for 4 hours to further break the dormancy of the seeds, improve the germination ability of the seeds, enhance the stress resistance of the radicle and germ, increase the germination rate of the seeds, and get frozen seed;

[0021] (3) Seed dressing: Add seed dressing agent to the frozen seeds,...

Embodiment 2

[0025] A treatment method for improving the germination rate of Magnolia magnolia seeds, comprising the following steps:

[0026] (1) Soaking: Select mature, plump, and complete Magnolia magnolia seeds, soak them in a compound enzyme solution with a mass concentration of 0.03% for 2 to 3 hours, destroy the seed coat structure, accelerate the softening of the seed coat, and initially break the seed dormancy , to accelerate seed germination, to soak the seeds; the compound enzyme is composed of the following enzyme preparations in parts by weight: ligninase 18, cellulase 14, hemicellulase 8, lipase 5;

[0027] (2) Freezing: Put the soaked seeds in the refrigerator and freeze at -9°C for 4 hours to further break the dormancy of the seeds, improve the germination ability of the seeds, enhance the stress resistance of the radicle and germ, and increase the germination rate of the seeds to obtain frozen seed;

[0028] (3) Seed dressing: add seed dressing agent to the frozen seeds, ...

Embodiment 3

[0032] A treatment method for improving the germination rate of Magnolia magnolia seeds, comprising the following steps:

[0033] (1) Soaking: Select mature, plump, and complete Magnolia magnolia seeds, soak them in a compound enzyme solution with a mass concentration of 0.04% for 2 to 3 hours, destroy the seed coat structure, accelerate the softening of the seed coat, and initially break the seed dormancy , to accelerate seed germination, to soak the seeds; the compound enzyme is composed of the following enzyme preparations in parts by weight: ligninase 19, cellulase 15, hemicellulase 9, lipase 6;

[0034] (2) Freezing: Put the soaked seeds in the refrigerator and freeze them at -8°C for 5 hours to further break the dormancy of the seeds, improve the germination ability of the seeds, enhance the stress resistance of the radicle and germ, and increase the germination rate of the seeds. seed;

[0035](3) Seed dressing: add seed dressing agent to the frozen seeds, mix well, an...

Abstract

The invention mainly relates to the technical field of planting and discloses a treatment method for increasing the germination rate of magnolia grandiflora seeds. The treatment method comprises the following steps: soaking seeds, freezing, mixing seeds, performing germination acceleration, and sowing the seeds. The method is simple, the magnolia grandiflora seed treatment time is shortened to 6-7days, buds can grow out within 5-6 days after sowing, the germination rate is up to 97.6%, the seedling breeding efficiency of the magnolia grandiflora seed is remarkably improved, and a great deal of seedling breeding cost is reduced; the magnolia grandiflora seeds are soaked in a composite enzyme solution, so that seed coat strucruers of the seeds are damaged, seed coat softening can be accelerated, seed dormancy can be primarily broken, and seed germination can be accelerated; after being soaked, the seeds are frozen for a short time in a refrigerator, then seed dormancy is further broken,the germination capability of the seeds is improved, the stress resistance of radicles and germs is improved, and the germination rate of the seeds is increased.
