Description
Technical Field
The invention relates to the technical field of plant cultivation, in particular to a method for breaking dormancy of wild anemone seeds.
Background
The long Mao Yin lotus (Anemone narcissiflora var. Crinita (Juz.) Tamura) and the silver lotus (Anemone cathayensis Kitag.) are wild ornamental plants of the genus Anemone of the family Ranunculaceae, and have high medicinal value. But is limited by natural environment conditions and artificial conditions, and the wild resources of the Mao Yin lotus and the anemone are very limited.
At present, the research on the long Mao Yin lotus leaves is blank, the research on the anemone leaves is mostly in the research on the phytochemical components and pharmacology of the anemone leaves, and no report is found on how to break the seed dormancy of the anemone leaves. The difficult germination is a bottleneck problem which restricts the large-scale cultivation of the long Mao Yin lotus and the anemone, and the propagation speed is slow depending on the rhizome, so that the medicinal production cannot be rapidly met.
Therefore, the search for suitable germination conditions is a fundamental way for solving the shortage of wild anemone germplasm resources.
Disclosure of Invention
In view of this, the invention aims to provide a method for breaking dormancy of wild anemone seeds, so as to solve the defects in the prior art.
In order to achieve the purpose, the invention adopts the following technical scheme:
a method for breaking dormancy of wild anemone seeds specifically comprises the following steps:
(1) Soaking wild anemone seeds in water, soaking in alcohol, and soaking in H 2 O 2 Sterilizing, and washing with water to obtain sterilized seeds for later use;
(2) Drying sand, sieving, sterilizing at high temperature and high pressure, naturally cooling to room temperature, moistening with water, mixing with sterilized seeds, and packaging into sterilized bags;
(3) Paving a first layer of sand on the ground surface in the cellar, then placing the sterilization bags in order, adding a second layer of sand on the upper parts of the sterilization bags, cutting the sterilization bags to be in an open shape with the sand surface level, and finally covering a third layer of sand on the upper layers of all the sterilization bags;
(4) And (3) placing the sterilization bag in a cellar for 90-100 days, then turning to room temperature and continuing to place for 10-15 days, then taking out the sterilization bag, and picking out germinated seeds for cultivation to obtain the wild anemone seedlings.
Further, in the step (1), the wild anemone is Mao Yin and/or anemone.
The technical scheme has the beneficial effects that the Mao Yin lotus and the anemone are wild ornamental plants of anemone in Ranunculaceae, and the medicinal value is quite high.
Further, in the step (1), the soaking temperature in water is 25 ℃ and the soaking time is 48 hours.
The method has the advantages that the germination time of the seeds can be obviously shortened by soaking the wild anemone seeds in water (seed soaking); and warm water is used to kill pathogens inside and outside the seeds by utilizing the characteristic that the heat resistance of the seeds is higher than that of pathogenic bacteria, so as to prevent and treat seedling diseases.
Further, in the step (1), the mass fraction of the alcohol is 70%, and the time for soaking in the alcohol is 30s.
The method has the beneficial effects that the germination rate of the seeds can be obviously improved by soaking the wild anemone seeds in the alcohol. Because the alcohol can play a role in sterilization, some viruses and bacteria of the seeds can be killed when the seeds are soaked, a temporary disinfection effect can be achieved, the germination of the seeds is facilitated, and the germination rate can be improved.
Further, in the above step (1), H 2 O 2 Is 15% by mass, H 2 O 2 The time for sterilization is 20min.
The beneficial effect of adopting the further technical scheme is that wild anemone seeds are treated with H 2 O 2 Sterilizing, not only eliminating pathogenic bacteria on seeds, but also soaking in H 2 O 2 The seed germination speed is faster, the seeds can grow healthier, and seedlings are not easy to fall down. Because of H 2 O 2 Oxygen is released during decomposition, and the requirement on oxygen content is higher during germination of seeds, so that H is properly used 2 O 2 The germination rate can also be improved by soaking the seeds in the solution.
Further, in the step (2), the temperature of the high-temperature high-pressure sterilization is 121 ℃ and the time is 20min or 135 ℃ and the time is 40min.
The sand sterilizing device has the beneficial effects that the sand is sterilized at high temperature and high pressure, so that common microorganisms such as bacteria and fungi can be killed, and spores can be killed.
Further, in the step (2), the volume ratio of the sand to the sterilized seeds is 3:1.
The beneficial effects of adopting above-mentioned further technical scheme lie in, through mixing sand and disinfection seed, can make the seed grain wrap up by wet sand completely, increase seed coat permeability, accelerate the inside metabolism of seed, accelerate the seed to accomplish physiological after-ripening, promote to germinate.
Further, in the step (3), the thickness of the first layer of sand is 10-15cm, preferably 10cm; the thickness of the second layer of sand is 5-8cm, preferably 5cm; the thickness of the third layer of sand is 10-15cm, preferably 10cm.
The further technical scheme has the beneficial effects that the first layer of ground sand can keep the temperature and the humidity of the bottom of the sterilization bag consistent with the ambient environment; sand is coated on the upper side of the second layer of open bags, so that water evaporation in the bags can be reduced, and the seed grains are ensured to be intact and not damaged when the fungus bags are taken; the third layer, which comprises the sand covered all around, can ensure that the environment around all the sterilization bags is consistent.
According to the technical scheme, compared with the prior art, the invention has the following beneficial effects:
1. according to the invention, through cellar stratification, the optimum germination conditions of Mao Yin lotus and anemone seeds are found to be 100d + 15d at room temperature, and the germination rates are 34.44% and 45.78% respectively.
2. The method greatly promotes the germination of the long Mao Yin lotus and anemone seeds, has simpler treatment conditions, is convenient to realize, and provides technical support for protecting and developing plant resources.
