Vernalization of bulbs refers to the process of storing bulbous plants at low temperature for a period of time, and then maintaining them normally before flowering and fruiting.
For example, bulbous plants such as daffodils, grape hyacinths, and tulips need to be refrigerated for a period of time before they can bloom after vernalization.
Although vernalization sounds simple, just storing the bulbs at low temperatures, improper handling can cause the bulbs to frostbite or rot, such as:
1. Use a plastic bag directly to put the bulbs into it for low temperature storage, because the bulbs cannot breathe in the plastic bag, and the moisture in the plastic bag will make the bulbs rot, so do not directly put the bulbs into the plastic bag;
2. Putting the bulbs wrapped in newspaper into a plastic bag for low temperature storage will also make the bulbs unable to breathe, and the condensed moisture will cause the bulbs to rot.
To properly allow bulbous plants to complete vernalization, you need to do this:
1. Because the bulbs themselves have moisture, it is the preferred material for wrapping bulbs to prepare packaging materials with good air permeability and water absorption, such as dry and clean newspapers.
2. When wrapping the bulbs with newspaper, it is recommended to wrap them separately, too much in a newspaper, it is easy to break the bud point, and the resistance to germs between different bulbs is different, which is easy to breed germs.
3. The temperature of vernalization of the bulbs is about 4 and cannot be lower than 0, so before putting the wrapped bulbs into the refrigerator, the temperature of the refrigerator should be adjusted, and then the bulbs should be put in after the temperature of the refrigerator. Do not let the temperature of the refrigerator be too low, causing frostbite to the bulbs, or put the bulbs in the freezer.
When placing the bulbs, place the bulbs with the bud point facing up and the base facing down, so that even when the bulb emerges, the bud point will not be crooked.
When you find that the newspaper wrapped around the bulbs is wet, you should replace the dry newspaper in time to avoid causing the bulbs to rot.
The low-temperature stored bulbs can be placed in the refrigerator for 1 to 2 months, and the low-temperature vernalization can be completed, and they can be taken out for planting, or they can be taken out for planting according to the time required for planting.
Here we need to remind flower friends that when buying bulbs, ask whether the bulbs have been vernalized, and if they have not been vernalized, they will be refrigerated and vernalized.
-
Intensify the temperature, water more, and then fertilize, and after these steps, the plants can quickly complete vernalization.
-
We must pay attention to the method of breeding, choose the right soil for processing, and pay attention to the temperature, so that we can better carry out vernalization.
-
Just put it in the refrigerator and pay attention to the temperature to be around 4 degrees Celsius.

Hyaluronic acid is super absorbent, and applying it to ** can absorb moisture from the air and help rehydrate epidermal cells. However, as opposed to its water absorption, its water retention is not generally poor. When you are in a dry environment, the water in the hyaluronic acid will evaporate quickly, and the phenomenon of back-absorbing cellular water will appear. >>>More
1. Take the wire: This is a necessary item for the car to take the electricity, do not take two wires to make do, because the instantaneous current of the vehicle at the start can reach 200-600A, and the diesel car even reaches 1000A, if it is calculated, 10 square copper wires can ensure the smooth and safe start, so the car battery connection line must buy the right brand, the quality is the best, do not try to be cheap. This is one of the must-have items in the car, once the battery is out of power, you can take it out and use it, and you can also help others when you don't use it. >>>More
