Can peanuts be sown with shells? How do you plant it? What's the advantage? What kind of fertilizer has high yield?

Peanuts are crops planted by farmers every year. They are not only good and useful, but also rich in nutritional value. Usually peanuts are shelled and planted. Today, the editor is going to talk about planting peanuts without shelling. Can peanuts be planted with shells? How do you plant it? What's the advantage? What kind of fertilizer has high yield?

Can peanuts be sown with shells? How do you plant it?

Peanuts can be sown with shells, which can increase product tax by 5% and 20% compared with peeling and sowing.

1. Deal with the seeds. The mid-early maturing varieties were mainly selected and the fruit was dried for 2-3 days before sowing. The double kernel fruit is broken into a single kernel fruit, and the single kernel fruit pinches the mouth open to facilitate the seed kernel to absorb water and emerge. Soak the pods in warm water of 35 ℃ for 6-8 hours, remove and drain the water before sowing.

2. Broadcast early at the right time. This method should be 20 days earlier than the local conventional sowing date, if the sowing time is too late, it will not play a role in increasing production. Peanuts sown with shells grow faster in the seedling stage, grow slowly in the middle and later stages, have short dwarf branches, and have a compact plant shape. It is necessary to increase the sowing density by 10%, 15%, and sow 11000 piers per day of 67 square meters (1 mu).

3. Appropriate shallow sowing. The seedling emergence of this method is slow, so it is not suitable for deep sowing, and the best sowing depth is 3-5 cm. Tread gently with your foot after sowing to avoid bringing the fruit shell out of the soil when it comes out of the seedling. For the seedlings that have been unearthed with shells, the fruit shells should be removed so as not to affect the growth of seedlings. In order to control underground pests, seeds can be mixed with seed coating agent for every 50 kg seeds. You can also use 40% isofenphos or 50% phoxim 100 grams, plus ±kg, sprinkled into the sowing ditch.

4. Strengthen the management. Check the seedling condition after emergence, and introduce the seedling to unearth, in order to reduce the weak seedling and dead seedling. During the growth period, it is necessary to promote the combination of control and prevention of diseases and insect pests. If the full flowering period appears to be overgrown, 0.1% dwarfin can be sprayed. When the number of aphids reaches 500, it is necessary to spray omethoate to control.

What are the benefits of sowing peanuts without peeling their shells?

The main advantages are that the seeds absorb water quickly, emerge quickly and grow neatly. At the same time, kernel selection can be carried out after shelling to ensure seed quality and improve seedling emergence rate.

Technical points for attention in peeling and sowing peanuts:

The main results are as follows: 1. The time of shelling should not be too early, the seeds lose the protection of fruit shell, it is easy to absorb water in the air, enhance respiration and enzyme activity, promote material transformation, consume a lot of nutrients, so as to reduce vitality. Slow emergence and irregular seedlings after sowing, it is best to shell before sowing and then peeling after sowing.

2. If the peeled seeds cannot be sown in a short time, they should be wrapped in plastic bags to prevent the seeds from being affected by moisture.

Third, what kind of fertilizer should be applied to peanuts with high yield?

Peanut has extensive adaptability to soil, but high-yield peanut field requires good soil conditions. It is most suitable to plant loose and solid sandy loam, rain can drain quickly without stagnant water, and drought can quickly permeate water. The amount of fertilizer absorbed by peanut at seedling stage is very small, but the lack of fertilizer will hinder the early development of strong seedlings and the formation of root nodules.

Principles of fertilization: 1. Organic fertilizer is applied in combination with inorganic fertilizer. Reasonable collocation of nitrogen, phosphorus, potassium and micro-fertilizer, adequate basic fertilizer and proper topdressing. two。 The content of peanut special fertilizer for topdressing quantity is 45% and 25 kg per mu. 3. Foliar fertilizer spraying is carried out in the middle and later stages according to the growth situation, such as boron, zinc (0.2%) potassium dihydrogen phosphate (0.1%) can protect leaves, roots, and prolong the functional period of the parietal lobe.
