Common misunderstandings in sowing the latest peanuts

Peanut is an important grain and oil crop in China, but the phenomenon of uneven emergence often occurs in the process of peanut planting, which seriously affects the economic income of farmers. The peanut seeding is mainly caused by three reasons, small noodles and Xiaobian together to see the common peanut planting errors bar.

1. Sowing time

Spring sowing peanut has a long growth period, so it is suitable for selecting middle and late maturing varieties. According to practical experience, spring peanut sown ten days early or ten days late, and the final yield difference is not large. Therefore, it is suggested that farmers should decide according to the local temperature when sowing, and sow after the temperature is stable. It is best to sow when the ground temperature is stable above 15 ℃. In addition, pay attention to the weather forecast when sowing, check the local weather changes within 15 days, and see that there is no significant cooling in the next half month. In addition, pay attention to rainy days. When it rains after sowing, peanuts will have a great chance of rotten seeds.

2. Sowing depth

Peanut sowing will mostly use hole sowing, drilling and mechanical sowing, and whether artificial or mechanical sowing, sowing depth should master the principle of dry not deep, wet not shallow ", the general sowing depth of about 5 cm is appropriate. When the soil temperature is low, the humidity is high, and the soil is sticky, it should be properly sown, but the minimum should not be less than 3 cm; and the loose sandy soil can be properly sown. However, the deepest should not exceed 7 cm, and the general soil sowing depth should be kept at 3-7 cm.

3. Seed dressing

In order to prevent diseases and insect pests, many farmers now have the habit of seed dressing before sowing, which is a good habit, but if the seed dressing operation is improper, it is possible to break the seed coat of peanuts, which will also cause uneven emergence of peanuts. This is because the seed coat of peanuts is very thin, and if the embryo is damaged, it will affect the emergence rate. In addition, attention should be paid to the amount of water should not be too much when artificial seed dressing, and in the process of stirring should be lighter, so as not to break the seed coat.
