Problems solved by technology

[0003] Cornus officinalis seeds are bound by a hard seed shell, which contains high germination inhibitors, and there is a layer of gelatin in the seed coat, which is not easy to absorb water. Therefore, the dormant period of field direct seeding seeds is as long as two years. Seedling rate is very low, at present, prior art has carried out a lot of researches to the dormancy reason of cornus officinalis and breaking method, such as (Liu Sixun etc., cornus officinale seed rapid seedling raising technique, " Chinese herbal medicine ", the 9th phase of the 19th volume, September, 1996 ), but the method is simple, not systematic, and the effect is not obvious

Embodiment 1

[0019] A method for raising seedlings of Cornus officinalis, comprising the following steps:

[0020] (1) During the fruit ripening season of Cornus officinalis, collect fruits with large fruit, bright color, full grains and no pests and diseases from the mother plant at the peak fruiting stage with good fruiting performance and no pests and diseases. After the skin is soft, peel off the flesh for planting;

[0021] (2) Spread the collected seeds in a ventilated and cool place, dry in the shade for 15 days and then use KH with a mass fraction of 4% to harvest the seeds 2 PO 4 Soak in the solution for 5 hours, the soaking temperature is 27°C, then soak in 0.1% mercury liter solution with a mass volume ratio for 9min for disinfection, and then rinse the seeds with clean water;

[0022] (3) Utilize the cold plasma generated by atmospheric pressure dielectric barrier discharge to process the cornus officinalis seeds obtained in step (2), the time for plasma treatment of seeds is...

Embodiment 2

[0026] A method for raising seedlings of Cornus officinalis, comprising the following steps:

[0027] (1) During the fruit ripening season of Cornus officinalis, from the mother plant with good fruiting performance and no pests and diseases, collect fruits with large fruit, bright color, full grains, and no pests and diseases in the sun for 4 days. After the skin is soft, peel off the flesh for planting;

[0028] (2) Spread the collected seeds in a ventilated and cool place, dry in the shade for 17 days, and use KH with a mass fraction of 5% to harvest the seeds first 2 PO 4 Soak in the solution for 6 hours, the soaking temperature is 28°C, then soak in 0.1% mercury solution with a mass volume ratio for 10 minutes for disinfection, and then rinse the seeds with clean water;

[0029] (3) Utilize the cold plasma generated by atmospheric pressure dielectric barrier discharge to process the cornus officinalis seeds obtained in step (2), the time for plasma treatment of seeds is ...

Embodiment 3

[0033] A method for raising seedlings of Cornus officinalis, comprising the following steps:

[0034] (1) During the fruit ripening season of Cornus officinalis, from the mother plant with good fruiting performance and no pests and diseases, collect fruits with large fruit, bright color, full grains, and no pests and diseases in the sun for 4 days. After the skin is soft, peel off the flesh for planting;

[0035] (2) Spread the collected seeds in a ventilated and cool place, dry in the shade for 20 days and then use KH with a mass fraction of 6% for the harvested seeds 2 PO 4 Soak in the solution for 7 hours, the soaking temperature is 30°C, then soak in 0.1% mercuric chloride solution with a mass volume ratio for 11 minutes for disinfection, and then rinse the seeds with clean water;

Abstract

The invention discloses a Macrocarpium officinalis seedling raising method, which includes steps of seed collecting, soaking, plasma treatment and multi-media stratification. Macrocarpium officinalis seeds treated by the method have increased germination rate, seed treatment cost is also reduced, the shortages of slow seed germinating speed and uneven seedling emergence are overcome simultaneously, original difficult seedling raising for tree propagation is simple and quick, the method is easy to popularize in production, and the germination rate can be up to 96%.

Description

technical field [0001] The invention relates to a method for raising seedlings of Cornus officinalis. Background technique [0002] Dogwood ( Cornus officinalis ), deciduous shrubs or small trees of Cornaceae. Its mature fruit is a traditional Chinese medicine, deciduous tree, up to 10m; the bark is gray-brown, the old branches are dark brown, and the young branches are green. It is a traditional Chinese medicinal material in my country, and its pulp has high medical value and economic value. [0003] Cornus officinalis seeds are bound by a hard seed shell, which contains high germination inhibitors, and there is a layer of gelatin in the seed coat, which is not easy to absorb water. Therefore, the dormant period of field direct seeding seeds is as long as two years. Seedling rate is very low, at present, prior art has carried out a lot of researches to the dormancy reason of cornus officinalis and breaking method, such as (Liu Sixun etc., cornus officinale seed rapid seed...
