Can fennel seedlings be left to regenerate? How long does fennel germinate

Fennel can be left stubble, but be careful not to hurt the pentatina strand when cutting fennel, it can grow again.

After fennel is planted, germination is slow, about half a month. If you want to be fast, it is best to soak the seeds in water at 15 to 20 degrees for a day before putting them in the soil, so that you can hurry up. It is better to cover the land with some grass to keep it warm.

The place with sunlight is the best.

First, stubble arrangement

Fennel is mostly cultivated in the open field in spring and autumn, that is, sown in March, April and July and September, and harvested in 40 to 55 days. It can also be cultivated in the greenhouse in autumn or in spring, so that fennel ** is delayed and advanced by 1 month.

Second, the selection of varieties

Fennel generally chooses varieties that grow fast, hardy, disease-resistant, and have high yields, such as Inner Mongolia cumin, Qingxian "Dajiao" cumin, etc. <>

3. Fertilization and land preparation

Apply 3,000 kg of high-quality rotting farmhouse fertilizer, 100 kg of superphosphate or 15 20 kg of diammonium per mu, apply to the ground, deep rake and fine furrow, furrow width meter.

Fourth, sowing

1.Seeding amount. Generally, 8 10 kg of seeds are sown per mu.

2.Seed treatment. Fennel seeds, as they are commonly called, are double hanging fruits containing two seeds that need to be rubbed open before planting.

Fennel can be dried seeds for direct seeding, seed sowing and germination sowing. In the spring cultivation of greenhouses, dry seeds are generally seeded or soaked, and germination and sowing can be promoted if the sowing date is late. Soaking seeds:

Soak in 18 20 water for 24 hours; Germination sowing: Put the soaked seeds in the 20 22 environment to germinate, rinse with water once a day to wash off the mucus, and germinate in about 6 days.

3.Sow. On the day of sowing, pour water on the leveled furrow. In order to achieve uniform sowing, the seeds can be sown in two parts. After sowing, sieve and sprinkle the soil 1 cm thick. <>

5. Field management

1.Temperature management. After sowing and before emergence, the closed greenhouse is insulated and cold-proof.

After the fennel seedlings emerge, the seedlings begin to release air when the seedlings are 7 8 cm high, generally more than 22 o'clock in the morning, and close the tuyere when it is less than 20 o'clock in the afternoon; In the middle of the day, the wind is released at 8 or 9 o'clock in the morning, and the air outlet is closed until 20 o'clock in the afternoon; In the later period, when the minimum outside temperature exceeds 3, the day and night ventilation should be large, the night tuyere should be small, and the maximum temperature during the day should not exceed 24, otherwise the fennel is easy to dry and tip.

2.Water and fertilizer management. When the seedling height is about 20 cm, water 1 time, the amount of water is moderate, combined with watering 10 15 kg of urea per mu.

Fennel seedlings can be transplanted.

Fennel seedlings can be transplanted, and seedlings can also be transplanted. If transplantation is chosen, it is best to choose it in the evening of spring, when the plant is not prone to water loss, the survival rate will be improved, and the transplanted fennel seedlings can absorb more nutrients from the soil and grow more vigorously.

Fennel seedling transplanting method.

1.Before transplanting fennel seedlings, the land should be prepared first. It is best to choose a garden soil with a fixed peat soil and humus in the belt state, which together form a nutrient soil, which is conducive to the survival of plants.

2.Planting. Next, fennel seedlings are planted in prepared soil.

After putting it in, the soil covered on it should be as loose as possible and not compacted, so as not to make it difficult for the roots of the plant to breathe.

Precautions for transplanting fennel seedlings.

1.A small number of fennel seedlings are transplanted into a new soil environment, and the root system has not yet adapted. At this time, watering should be reduced or not watered as much as possible, so as not to accumulate too much water in the soil, which will affect the respiration of plant roots and limbs, and lead to waterlogged death.

2.Avoid exposing fennel seedlings to the sun. During the initial transplant, this was a very fragile period.

If directly exposed to bright light, it can easily cause the plant to be burned or die from water loss, so try to avoid it.

<> fennel seedlings can be transplanted. When fennel seedlings grow to 5-6 cm when transplanting, transplanting should be carried out with soil, keep the plant distance of 4 cm, strengthen management after planting, do a good job of weeding, watering, top dressing, etc., appropriate watering can be, when the seedling height is about 10 cm, top dressing, generally 20-30 kg of biological fertilization per mu, weeding do not use pesticides, which will hurt fennel seedlings, it is best to carry out weeding manually, and pay attention to pest control.

Can the fennel be cut and sold again?

Answers. 1.Fennel can be grown again after cutting, and if it grows in a good environment, it can be harvested again in about ten days.

2.When there is a lot of fennel, you can harvest more than a dozen stubbles, but there is also a situation that it will no longer grow after harvesting a few stubbles, which is likely to be caused by cutting it, so it is also necessary to have skills when harvesting, and you need to leave about ten centimeters of stems at the bottom of it to make trouble.

1. Planting timeFennel can be sown in spring and autumn, with a good sowing time in March and April in spring and September in autumn, the climate is warm and suitable for light and soil conditions, which can maximize seed germination. Therefore, choosing the right time for sowing is extremely important.

2. Seed selection3. Land selection and land preparationFennel is actually not very demanding on the soil, not picky at all, and can be planted in general soil, but it is most suitable for planting in loose and fertile, sandy soil with strong drainage and irrigation function, and the soil pH should be moderate. Before sowing, the soil should be finely leveled, the soil should be turned at least 35 centimeters deep, the soil should be finely adjusted, and the foot fertilizer should be applied, and the ground should be leveled again.

4. Sowing method

A simple treatment is needed to ensure that the fennel seeds are better fertilized. But don't deal with it in a big way.

Fennel seeds need to be treated before planting cumin, as fennel seeds are small and may contain many grass seeds, so they should be removed.

The fennel seeds need to be treated and some complicated processes are required before the fennel can be planted in the land.

Fennel is unearthed in 6 7 days, and sometimes it is unearthed in 8 or 10 days.

After fennel seedlings and time seedlings, keep the plant spacing of 4 cm, and combine the seedlings to pull out weeds.

Top dressing is carried out when the seedling height is about 10 cm. Generally, biological flushing fertilizer is applied per mu, and the dosage is 20 to 30 kg per mu. If multiple harvests are made, the same amount of fast-acting fertilizer is applied after each harvest.

Fennel is not drought tolerant and should be watered immediately after sowing. After the emergence of seedlings, the watering should be properly controlled for squatting seedlings, and the seedlings should be watered frequently when they are 10 cm high until harvest. When the new shoots grow about 2 cm after stubble cutting, water and fertilizer again, and turn the ground and pour the stubble after harvesting 3 to 4 stubbles.
