Problems solved by technology

[0003] When sowing seedlings, because there is a layer of colloid in the seed skin, it is not easy to absorb water, so the seed germination rate is not high, the seed waste is serious, the emergence is uneven, and the cost of artificial seedlings rises

Embodiment 1

[0016] A method for improving the germination rate of dogwood seeds, comprising the following steps:

[0017] (1) During the fruit ripening season, collect mature fruit from excellent dogwood trees with strong growth, high and stable yield, and no pests and diseases, remove the pulp, rinse with clean water to obtain clean seeds, and sprinkle phosphorus pentoxide powder on the surface of the seeds , can absorb water on the seed coat, weaken the respiration of the seeds, and prevent low germination rate and uneven emergence caused by nutrient consumption. The dosage is based on covering 70% of the seed coat. Constantly turning over, drying seeds evenly;

[0018] (2) Collect the sun-dried seeds, place them in an environment with a relative humidity of 55% and a temperature of 32°C, and alternately irradiate them with high-pressure sodium lamps and ultraviolet high-pressure mercury lamps every day. The high-pressure sodium lamps are irradiated for 2.5 hours. The irradiation time ...

Embodiment 2

[0026] A method for improving the germination rate of dogwood seeds, comprising the following steps:

The dosage is based on covering 75% of the seed coat. Constantly turning over, drying seeds evenly;

[0028] (2) Collect the sun-dried seeds, place them in an environment with a relative humidity of 57% and a temperature of 34°C, and alternately irradiate them with high-pressure sodium lamps and ultraviolet high-pressure mercury lamps every day. The high-pressure sodium lamps are irradiated for 3 hours. The high-pressure mercury l...

Abstract

The invention relates to the field of Cornus officinalis Sieb planting, and discloses a method for improving the seed germination rate of Cornus officinalis Sieb. Before seeding, seeds are subjected to a series of treatments by physical and chemical means; the nutrient substances in the seeds are locked and are not consumed; meanwhile, the seed dormancy is fast broken; through a series of treatments, seed coats are permeable and ventilated; seed embryos are accelerated to absorb water and expand for budding; seedlings obtained by the method provided by the invention can realize direct transplanting in fields; the step of seedling hardening is omitted; the labor and the materials are saved. The method has the advantages that the seed germination rate of the Cornus officinalis Sieb is improved to be 98.6 percent; the budding is regular; the seedling shape is good; the seedling culture cost is reduced by 34.0 percent.
