Seed treatment of pea before sowing

Pea planting is the use of sowing reproduction, in order to improve the germination rate, farmers generally have to carry out a series of treatments on the seeds before sowing. So how to choose the seeds? How can we improve the germination rate? Let's take a look at the detailed introduction with the editor.

1. Seed selection

The seeds should be carefully selected before sowing, and the diseased insect species, broken seeds, small seeds, blighted seeds, mixed grain weight and heterochromatic seeds should be removed. This can reduce the harm of diseases and insect pests, improve the uniformity of sowing, and ensure that the seedlings are neat and consistent after they are unearthed. If the sowing amount is too small, the method of selecting seeds by hand can be used, and when the amount is large, the seeds can be screened by sieve or 40% salt water. If the seeds are poured into salt water, the inferior seeds will float on the water surface and remove them, while sinking at the bottom of the water can be used for sowing.

2. Seed drying

Leave the selected seeds in the sun for 3-5 days, which can significantly improve the germination energy and germination rate of the plant. pay attention to the sunny and sunny time when drying the seeds. Spread a layer of towel or gauze on the ground, spread the seeds evenly, the thickness is about 5cm, turn from time to time when drying the seeds, so that they are heated evenly. Drying seeds can kill the germs and eggs carried on the seed surface and reduce the harm of seed diseases and insect pests.

3. Soaking seeds to accelerate germination

After low temperature vernalization treatment, pea seeds can reduce flowering nodes, make them blossom earlier, promote branching, improve harvest and increase yield. First soak the seeds in cold water for 2 hours, make the seeds fully moist until the seed coat is swollen, then remove them, wrap them with towels or gauze, and accelerate germination at room temperature of 15-20 degrees for one day. Rinse with clean water every 2 hours to replenish water. Wait until the seed germ is exposed, put it in a low temperature of 0-5 degrees to deal with 10-12, refrigerator can also be refrigerated, you can sow.

4. Rhizobium mixed with seed

The seeds treated with low temperature vernalization can be mixed with rhizobium again, which has the advantage of increasing the number of root nodules of seedlings, promoting the growth of stems and leaves, making them more pods and increasing yield. The method of seed dressing is also very simple, the general amount of seed per mu, plus 10-15 grams of rhizobium powder plus the right amount of water, it and the seeds can be stirred.

The above is the introduction of seed treatment methods before pea sowing. I hope it can help you. If you want to know more about it, please follow us.
