What Are The Reasons For The Low Rate of Seed Germination?
1. Seed soaking time of different seeds is different in different time, with short soaking time, insufficient water absorption and low germination rate;
2. The water absorption and germination rate of seeds are closely related to the temperature environment. If the temperature of soaking seeds and accelerating germination is too high or too low, it will make the seeds unable to absorb water and the germination temperature unsatisfactory, resulting in a low germination rate.
Here is how to effectively improve the success rate of seed germination:
Ⅰ.Sunning The Seed And Choosing Good Seed
Prior to seed hastening, seeds should be dried and selected in advance. Sun planting has the following advantages: improving the water absorbing ability of seeds, killing some pathogenic bacteria on the outer shell of seeds, making the seed germination rate high and the seedling orderly, making the seedling grow strong and the disease is less.
1. Seed drying: the seeds should be spread evenly on a sunny day 2 to 3 days before accelerating the germination. The seeds should be spread thin when planting, and the seeds should be turned over frequently in the process to make the seeds more even.
2. Seed selection: full and full seeds will have a better germination rate and seedling situation. Therefore, it is necessary to conduct seed selection before accelerating germination.
Many seeds are smaller (vegetable seeds, for example) and are difficult to pick. Seeds can be selected with water or salt water: seeds of common varieties can be screened with salt water, and mixed seeds are best screened with water. Empty granules can be removed with clean water, and empty granules can be eliminated with salt water.
A lot of people have such a problem that we use clear water to select a species, but the concentration of salt water to select a species is not easy to grasp, how to do? Tell you a relatively simple method: when the salt water is ready, you can put an egg into it. If the eggs are all submerged under salt water, it indicates that the concentration of salt water is too low and salt needs to be added. When an egg shows only a coin's worth of salt water, the concentration of salt water is appropriate. This method is very simple. Have you learned it?
Ⅱ.Infested The Seed
In order to improve the quality of sowing, it is better to disinfect seeds before sowing, which can significantly improve the rate of germination and greatly reduce the occurrence of diseases and pests in a later stage. So how do we do that?
Scorched by kinds of seed, seed selection, wash, in 50 to 55 degrees warm water soak 10 to 15 minutes, remove the fish in clean water and soak for 2-3 days (seed different soaking time, such as tomato seed soaking for 24 hours, the balsam pear, towel gourd seed soaking 48 hours), every 4-5 hours in a clear water, when the seed soaking water quantity for around 50% of seed weight, seed has been absorbing water saturation, at this time to sprouting at this moment, the highest germination rate. In the process of seed soaking, if the seeds are sterilized with 1, 000 times of polymyxin, it can better reduce the occurrence of seedling diseases after sowing.
Ⅲ . Sprouting Operation
If you have the condition, it is better to use the terminator, which is convenient for constant temperature and humidity, so as to better control the temperature and humidity of the germinator.
Method:
Insulation: a 60W LED grow lights suspended in a small hole on the top of the foam box. The bulb is 20 cm away from the seed and used only when the temperature is low.
Moisturizing: put a clean and wet cloth on the bottom of the box, put in seeds, and cover with a wet cloth;
Plug in the thermometer from the top of the box and check the temperature at any time.
Specific operation: For soaking seeds out of ventilation to dry, then use clean gauze wrapped seeds such as (parcel is the seeds cannot too tight, should leave some space for seed germination), on heat preservation box or indoor environment sprouting (can fit into a thermometer all the time, in order to grasp the sprouting temperature at any time, check temperature once every 5 hours), constant temperature environment seeds in 30 to 32 generally in about 12 hours can break the chest, and then control the accelerating seed germination temperature to 25 to 28 degrees continue sprouting, under the condition of constant temperature, average 24 hours to rush budding strong kind of bud, bud of the standards, The germination rate is generally above 90%, when 60-70% of the seed germination can be used to sow seeds.
Of course, for some friends who like to plant flowers, you can simply use a paper towel for budding. The operation is as follows: find a sealed pot, wet the paper towel and spread it on the bottom of the irrigation, then spread the flower seeds evenly on the paper towel, cover the cover and put it in the warm shade, usually after a few days, the flower seed can germinate. Or place washed flowers on a wet towel and cover them with a clear glass cover. For those seeds with thick and hard shells, they should be soaked before budding.
1. Seed soaking time of different seeds is different in different time, with short soaking time, insufficient water absorption and low germination rate;
2. The water absorption and germination rate of seeds are closely related to the temperature environment. If the temperature of soaking seeds and accelerating germination is too high or too low, it will make the seeds unable to absorb water and the germination temperature unsatisfactory, resulting in a low germination rate.
