How to improve the germination rate of tiny seeds
The editor introduces you to the related content of flower propagation, how to improve the germination rate of tiny seeds, the specific details are as follows:
In flower cultivation, it is often encountered that播种 some very small seeds result in few seedlings, or even no seedlings at all. How can we make them germinate better?
Firstly, understand the characteristics of the seeds, including the required temperature, humidity, light, and soil, which is very crucial. For example: German primroses should not be soaked, as the seeds may lose vitality after soaking. Seeds of dwarf petunias and tuberous begonias need to be kept at about 25°C; if soaked and then placed in a low-temperature environment for 1-2 days, the seeds may rot and no seedlings will emerge.
Secondly, choose the right sowing equipment, such as a hard plastic seedling box that is 50-60 cm long, 30-40 cm wide, 8-10 cm high, and has many small holes at the bottom. You can also make one with wooden boards yourself, depending on the amount of seeds to be sown, but it should not be too tall. The bottom of the wooden box should have drainage holes and must be soaked in water for 2-3 days before use to ensure it is fully soaked, otherwise, the box and soil may separate.
Thirdly, prepare the substrate by mixing well-rotted and sieved manure, humus, fine sand, and garden soil in a ratio of 2:1:1:1, sieve them with a sieve that can sift down millet, and then expose them to sunlight for disinfection for a day.
Fourthly, prepare the box by first laying a layer of soybean-sized coal cinders 1-2 cm thick at the bottom of the box. Then place the prepared substrate on top and level it, about 4-5 cm thick. Next, use the top of the sieve to sprinkle a layer of fine substrate, about 1 mm, to fill the soil particles, so that the tiny seeds do not fall into the soil and fail to break through. However, do not use too much fine soil, as it may easily grow moss.
Fifthly, sow the seeds.
Mix the seeds with fine sand at a ratio of 1:1000-2000 in a pot, and sprinkle them evenly on the substrate. Then gently press the seeds into the soil with a smooth board, without compacting them, just enough to make the seeds adhere to the soil. Finally, soak the wooden box in water, ensuring that the water level does not exceed the soil surface, adding water as needed until it is fully soaked. Remove the soaked box from the water, cover it with glass to retain moisture (do not use plastic wrap as it may drip and harm the seedlings), slightly control the water, and immediately move it to an environment suitable for seed germination. Once the seeds have germinated, remove the glass and move them to a suitable growing environment after most of the seedlings have emerged. It is important to note that you should not water or spray water from above until the seedlings have grown two true leaves. Other aspects should follow normal seedling management.
The above explanation on how to improve the germination rate of tiny seeds is hoping to bring a little help to your life!
