The latest corn seed germination method

Corn is one of the most important food crops in China, which is widely planted and distributed in our country. Generally speaking, we sow corn seeds directly, and there is no need for germination treatment, but because the growth period of some maize varieties is longer, in order to promote the rapid emergence of corn seeds and improve the emergence rate of corn seeds, then germination treatment is also very important. Today, let's learn how to accelerate the germination of corn seeds.

1. Seed soaking treatment

Generally speaking, we all need to soak the corn seeds before sprouting, so how do we soak the seeds? A week before sowing, soak the selected seeds in cold water, human urine, warm water, potassium dihydrogen phosphate, rice vinegar and potash fertilizer. Due to the use of different seed soaking materials, the soaking time is also different, which is 8 to 10 hours, 6 to 12 hours, 8 to 12 hours, 10 to 12 hours, 24 to 36 hours, and 12 to 24 hours respectively.

2. Sprouting method

When the seeds are soaked for a long time, we need to fish out the seeds and wash them in warm water of about 50 degrees. Then prepare the fire pit or equipment that can keep warm, spread a layer of plastic sheet, pile up a layer of straw, put a layer of gunny bag or cotton cloth on the straw, and finally spread the washed corn seeds on the prepared budding equipment, which is about 10 centimeters thick, and cover the seeds with a layer of gunny bag or cotton cloth for heat preservation and moisturizing. Of course, we also need to put a thermometer in the middle of the budding seeds to facilitate observation and control of the temperature. When sprouting, the temperature is generally controlled between 25 and 30 degrees, and the seeds are turned every 60 minutes or so and watered every 12 hours to avoid burning corn seeds.

3. The way of drying

After accelerating the germination of corn seeds, we need to dry them, because in the process of accelerating germination, we have to water them. Generally, the time for accelerating germination is 36 to 48 hours. Put the seeds in a cool and ventilated place to dry, and then pick out some seeds that do not sprout obviously or not. Finally, after the surface of the seeds is dry, you can sow the seeds, not too dry, otherwise it will still affect the emergence of seedlings after planting.

4. Points for attention

When sprouting corn seeds, there are a lot of problems that we need to pay attention to. Generally speaking, the most important points are the following. The first is to buy a kind of coated seeds, we have to remove the seed coating and coating before sprouting. The second is that the bud point of corn seed germination is not too long, otherwise it will also affect the quality of the next seed. In addition, when the seeds are ready to sprout, we need to pour the ground thoroughly and sow seeds in sitting water. Finally, it is best to promote germination by stages, not at one time, and the temperature of drying at the same time is about three or four degrees to control the growth of seed bud points.

The above is the method of accelerating the germination of corn seeds that the editor wants to share with you today. I hope I can help you. If you want to learn the high-yield technology of corn, you can also follow us.
