When is fennel good to grow How to increase yields by planting fennel

There are three types of fennel: cumin, anise, and bulb fennel. Fennel is dark green in color and has a special fragrance, the seeds and fruits can be used as spices and medicines, the stems and leaves are used for food, and most of the most commonly eaten in our daily life is cumin. It is very nutritious, rich in vitamins and carotene, often eaten is good for the body, the most important is the unique fragrance of fennel even insects dare not approach.

Therefore, the planting management is relatively simple, neither insects nor easy to get sick, but it can be harvested in more than a month, harvesting a stubble and growing a stubble, and many farmers like to plant a kind of fennel. So how do you grow a delicate and high-yield fennel?

1. The best time to plant fennel

Fennel prefers a cool climate, and is generally best sown in spring and autumn. It grows at a temperature of 15-26 degrees, fennel is not strict with the soil, and if you want to cultivate soft and high-yield fennel, you should choose a place with loose and fertile soil, plenty of sunshine, high and flat terrain, and good drainage.

2. Turning the field before sowing

Do not sow seeds immediately after harvesting crops, and plowed the land early in advance when it is sunny. The use of sunlight and ultraviolet rays to kill the original bacteria and insect eggs contained in the soil, through the whitened soil is conducive to the growth and development of fennel in the future. A few days before sowing, the land is finely prepared again, if there is compost from the well-rotted farmhouse, 3000 kg of crop base fertilizer is put into each mu, and a small amount of nitrogen, phosphorus and potassium compound bottom fertilizer can be used without farmhouse fertilizer, 20 kg per mu.

The soil and fertilizer are finely crushed by manual or agricultural machinery, and the plots are leveled into flat fields, but they can be sown in two or three days.

3. Sowing seedlings

It is best to dry the seeds for 1-2 days after buying seeds, drying the seeds can effectively kill the bacteria adhering to the seeds, reduce the water content of the seeds, make the seeds absorb water after sowing, and the seeds can quickly absorb the water in the soil, improve the germination rate, and the seedlings will emerge quickly. After sowing, there are plant ashes that can be sprinkled together to mix seeds, and then covered with a layer of 1 cm thick fine soil, watered once until the soil penetrates and moists. Fennel sprouts about 8 days after sowing, and generally does not need topdressing at the seedling stage, and the soil should be kept dry and moist.

4. Water and fertilizer management

When fennel grows to 8 cm high, it has entered the vigorous growth period, pay attention to its growth density, and the growth of too dense should be weak and strong, and ventilation and light transmission are required. In addition, it is necessary to strengthen the attack of water and fertilizer, promote the rapid growth of fennel, cultivate young fennel, use 50 kg of nitrogen, phosphorus and potassium compound water per mu and 2000 kg of water, you can also directly apply deep fertilizer, and the rhizome should keep a distance of 5 cm, and then according to the picking and growth situation. In short, if you want to grow good quality and soft fennel, the most important thing is artificial topdressing water management, as long as it is well managed, there will generally be no pests and diseases.

It is best to plant fennel in March every year. The soil should be disinfected in advance, insect pests in the soil should be removed in advance, the soil should be turned in advance, when planting fennel, the seeds of fennel should be soaked in warm water overnight, and when planting fennel, a layer of plastic film should be laid, which can increase the yield.

I planted it in May, and I feel that the yield is not bad, and I need to fertilize more and cut the leaves more to grow fennel.

Autumn fennel planting, generally after the beginning of autumn can be planted, because fennel is cold-tolerant, so it can also be appropriately postponed according to the local climate characteristics, but it is best not to exceed mid-September. There are three varieties of fennel, cumin, and bulb fennel, and the variety of anise is high, the growth period is short, but the fragrance is lighter. Cumin is shorter than cumin, but the fragrance is heavier and the taste is better, and cumin is grown in many regions.

When the bulb fennel grows to a certain stage, its branches and stems will be huddled, the yield is the highest, and the fragrance is the lightest, but all three varieties can be sown in autumn, and you can choose the variety according to your preference. Fennel has relatively low requirements for the growth environment, but if you want to make fennel yield high, it is best to choose to plant in sandy soil with fertile soil and good drainage performance.

Fennel is generally planted in spring and September. Because fennel has good cold resistance, it is very good to plant after the beginning of autumn. However, some growers will postpone the planting of fennel seedlings according to local climatic conditions, but it is best not to go beyond mid-September.

Fennel seedlings are planted at the same time.

Two. How to grow fennel seedlings.

1.Breed selection.

Generally, fennel is divided into cumin and bulbous fennel. There are many varieties of fennel, the growth period is short, the fragrance is light, and the bulb fennel fragrance is good. It is generally recommended to plant fennel, but it can also be selected according to market demand.

Fennel seedling planting method.

2.Soil selection and fertilization.

Fennel prefers to live in sandy soil, which is fertile and has good drainage properties. Before planting fennel, apply enough fertilizer and choose a fully decomposed field fertilizer. After applying basal fertilizer, it can be planted in deep ploughing.

3.Cultivation management.

The seeds of fennel are small. Generally, seedlings need to be raised before planting. After sowing, an appropriate amount of sand and enough water can be added to evenly distribute the fennel seedlings. Generally, fennel seeds can emerge 7 days after sowing.

4.Seedling management.

Fennel grows slowly in the early stage and fast in the later stage. In order to increase the yield, the growth rate of fennel should be increased in the early stage. The main methods to improve the growth rate of fennel in the early stage are weed control and water and fertilizer application control in the later stage.

5.Harvest. The best harvest height for fennel is about 20 cm, and it can be harvested once or twice.

If harvested, fennel can be cut off along with the stems and roots. If it is a secondary harvest, the stem of fennel should be cut one centimeter away from the soil, and 2 to 3 days after harvesting, it should be watered and fertilized in time to promote the secondary growth of fennel.

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.

Cumin is a long-sunshine, semi-cold-tolerant, early-tolerant, cold-loving dicot spring crop, which is more drought-tolerant but not waterlogging-tolerant. The growth period after emergence is 65-85 days. The fertility process is fast and adaptable. In northern China, it is mainly cultivated in spring and autumn. (Open field cultivation).

Spring sowing: late March, early April, mid-May to June.

Autumn sowing: July to August, harvest from September to October.

The cumin flavor is spicy, sweet and warm. It has the functions of regulating qi and strengthening the stomach, dissipating cold and relieving pain.

Cumin can be fried, salad, steamed buns, dumplings, and has its own fragrant taste.

Fennel planting time and method.

Fennel planting conditions: (1) Light. Fennel is a shade-tolerant tree species, and the light required at each stage of the growth process is different, the seedlings need good shelter conditions, and the fruiting adult trees need enough light.

2) Temperature. It is better to have an average annual temperature of 16-23. In winter, when the temperature drops to -3, the young trees will be, and the temperature will drop to -6 large branches will freeze, and some plants will die.

3) Moisture, fennel likes humid climate, normal annual precipitation of 1000 2800 mm, 1800 2300 mm is more suitable, relative humidity is not less than 78%. (4) Topography and soil. Fennel is better at an altitude of 500 to 1000 meters, and shady or semi-shady slopes should be chosen, and the middle and lower slopes are conducive to the growth of fennel.

The soil layer is fertile, acidic soil, and fennel cannot grow in places where there are often strong winds on mountains, slopes, and cols.

Fennel planting time.

Fennel is cultivated in all provinces and regions of Tongfuming, and can be sown in spring and autumn, from February to May in spring and from July to September in summer.

Fennel growth cycle.

Fennel grows for 45-60 days. If you plant in March, you will harvest in May and June. If it is planted in July-August in autumn, it will be harvested in September-October.

Fennel Cultivation Costs and Profits.

Fennel is relatively saturated in the market. The cost is not high, but for today's growers, it is not profitable. The yield per mu of fennel hall chain incense is about 2,000 to 3,000 catties, and the total income is 6,000 to 9,000. After removing costs, the economic profit is relatively low.

Fennel planting technology points.

1.Germination: For fennel to germinate quickly, it is best to soak the seeds for 24 hours, then place the seeds in a clay pot and cover with a damp cloth for germination.

2.Planting: Cumin is densely planted with wet seeding.

After sowing, pay attention to frequent watering. After the seedlings are unearthed, weeds are easy to grow in the field. Weeding should be done to keep the bed surface dry and moist.

3.Multiple cropping: If multiple harvests are planned, fast-acting nitrogen fertilizer should be applied in conjunction with watering.

Harvest the residue, grow new shoots, top dressing and watering, and nurture growth.
