At the same time, it can regulate water quality and promote high yield and high quality. So what are the seed dressing methods for peanuts? What should I pay attention to? Come and have a look with the editor.

1. Seed dressing with medicament

Seed dressing agents can be selected according to local diseases and insect pests, generally, carbendazim methyl, carbendazim, mixed seed and other agents can be used, and the dosage can be 0.3%-0.5% of the seed amount, which can effectively prevent rotten roots and dead seedlings.

2. Seed dressing with water-retaining agent

Peanut water-retaining agent is a kind of macromolecule water-absorbing and hydrophobic branch, and it is a very excellent water-retaining material. It can absorb hundreds of times the weight of seeds and is suitable for use in dry and thin land. Generally, it can increase production by 10%. The method is to wet the seeds, spread them evenly at 150-300 grams per mu, then stir them evenly, or coat them. The water-retaining agent can also be put into clear water and stirred while adding, causing the water-retaining agent to absorb and expand quickly until it is mixed into a paste, then pour into the seeds, keep stirring, mix well and spread out to dry in preparation for sowing.

3. Seed dressing with seed coating agent

Peanut seeds can also be coated by seed coating agent, which can play an excellent sterilization, insect control, improve seed vigor, avoid or reduce the impact of adverse environment, but also conducive to seedling Qi, seedling strong, promote seedling early development.

4. Points for attention

Try to choose the seed coating agent with high efficiency and low toxicity to ensure the safety of seedling emergence, first pour the agent into the container, add a small amount of water to stir, then pour in the seed fertilizer, and finally evenly mix the seeds. In the seed dressing agent can stir the seeds evenly, the less water is added, the better, too much water is easy to cause seed wrinkles and peeling. No matter when the seeds are stirred manually or mechanically, the shorter the stirring time is, the better under the premise of mixing the seeds evenly, and spread out after mixing the seeds to dry, do not sulk the seeds, do not expose to the sun.
