How to improve the germination rate of leek seeds

Leek is one of the common vegetables in our life. Leek is propagated by sowing. It is very important to plant leek to improve the germination rate of seeds, because only when the seed germination rate is increased, the economic benefit will be higher. So how to improve the seed germination rate of leek? Let's take a look.

1. Seed selection

Seed selection before planting is also extremely serious. Seeds purchased, whether in bags or in bulk, should be placed in the sun for 2-3 days. Pay attention to the fact that when drying seeds, they should not be in direct contact with the ground. They can be covered with gauze or put into other containers. When drying the seeds, turn the seeds several times to make them heated evenly. After drying the seeds, the wind selects and removes the blighted and mildew seeds, leaving the seeds with full particles and free from diseases and insect pests to make seeds.

2. Soak the seeds in warm water

Put the seeds in warm water of about 20 degrees to make them gradually enlarge in warm water, enhance the germination rate and adaptability, and further remove the blighted grains. Soaking seeds in warm water should not use too much water, just soak the seeds, too much water may affect the germination rate of seeds. Soaking seeds in warm water takes 10-12 hours, so in order to keep warm and control the temperature, you can put it in the incubator. If not, you can use quilts and hot water to keep warm.

3. Hot seed at high temperature

After soaking the seeds in warm water, the next step is to blanch the seeds at high temperature. at this time, the high temperature heat of the water will kill the germs on the surface and inside of the seeds. at the same time, it can also break the dormancy of the seeds, increase vitality and facilitate germination. Hot water of hot seed should be controlled between 50-60 degrees, and the time of hot seed should be controlled within 20 minutes, but it is too high or too long. At the same time, in order to maintain the water temperature, you can use a thermometer to detect and heat water if the water temperature is too low. Hot seed is to constantly stir, so that it is heated evenly, hot seed after rinsing clean, dry waiting for budding.

4. Disinfection and budding

In order to ensure the cleanliness of seed disinfection and sterilization, the seeds can be soaked in low concentration copper acid solution for 5 minutes or low concentration of Dysen zinc for 15 minutes. After cleaning the plant, wrap it with clean gauze and put it in a container. The mouth of the container is covered with a wet cloth and budding in a greenhouse about 20 degrees Celsius. When sprouting, the temperature should be controlled, and it should be turned frequently and rinsed with warm water once a day to increase the air permeability of the seeds so as not to die from lack of oxygen. After washing, the germination is accelerated and the operation is repeated. Generally, after 2-3 days, 1/3 of the seeds can be sown when they are white.

The above is the introduction of how to improve the germination rate of leek seeds, hope to help you, want to know more related knowledge, please pay attention to us.
