What seed treatment methods are there for peas before sowing?

Peas are propagated by sowing when planted. When planting, farmers generally carry out a series of treatments on the seeds before sowing in order to increase the germination rate. So how should the seeds be selected? How can the germination rate be improved? Let's take a look at the detailed introduction together.

1. Seed selection

Before sowing, the seeds must be carefully selected, removing diseased and insect-damaged seeds, broken seeds, small seeds, shriveled seeds, and seeds mixed with different grain weights and off-color seeds. This can reduce the harm of diseases and insect pests, improve the uniformity of sowing, and ensure that the seedlings emerge uniformly and consistently. If the sowing quantity is too small, the method of manual seed selection can be used, while when the quantity is large, screening with a sieve or seed selection with 40% salt water can be used. Pour the seeds into the salt water; inferior seeds will float on the surface of the water, and these should be skimmed out and discarded, while those that sink to the bottom can be used for sowing.

2. Sunning the seeds

Place the selected seeds in the sunlight to dry for 3-5 days, which can significantly improve the germination vigor and germination rate of the plants. When sunning the seeds, pay attention to choosing clear weather and bright sunshine. Spread a layer of towel or gauze on the ground, spread the seeds evenly on it at a thickness of about 5 cm, and turn them from time to time while sunning so that they are heated evenly. Sunning the seeds can kill the pathogens and insect eggs carried on the surface of the seeds and reduce the harm of seed-borne diseases and insect pests.

3. Seed soaking and germination promotion

After the pea seeds undergo low-temperature vernalization treatment, the node position of flower formation can be lowered, causing them to bloom earlier and promoting branching, improving harvest and increasing yield. First put the seeds in cold water and soak for 2 hours, so that the seeds are fully moistened until the seed coat swells, then remove them, wrap them in a towel or gauze, and place them at a normal temperature of 15-20 degrees to promote germination for one day. During germination promotion, rinse them with clean water once every 2 hours to replenish moisture. After the seed embryo buds appear, place them in a low-temperature environment of 0-5 degrees for 10-12 [hours]; the refrigerator compartment is also fine, and then they can be sown.

4. Mixing seeds with rhizobium

Seeds that have undergone low-temperature vernalization treatment can then be mixed with rhizobium. The advantage of doing this is that it can increase the number of root nodules on the seedlings, promote stem and leaf growth, make them form more pods, and increase yield. The method of mixing seeds is also extremely simple. Generally, for the seed quantity used per mu, add 10-15 grams of rhizobium powder plus an appropriate amount of water, and then stir it with the seeds.
