The planting method and time of fennel, sowing in spring and autumn, pay attention to seed treatment and fertilization

The best planting time of fennel is from March to April in spring and from August to September in autumn. If fennel is planted in winter, greenhouse technology should be used. Planting method: First of all, full and complete seeds should be selected. They can be soaked in warm water for about 12 hours before planting. The soil should be covered with film after sowing in autumn. When there are true leaves, seedlings should be thinned and supplemented. Fertilization should be carried out during growth. When fennel plants grow to about 30cm, they can be harvested.

The planting time of fennel

Fennel is used in a wide range, is a familiar spice, but also a medicinal material. Fennel is usually grown in two seasons, March-April in spring and August-September in autumn. If you want to choose winter planting, you need to use greenhouse technology, and summer planting its yield and quality can not be guaranteed.

How to grow fennel

1. Seed selection

Fennel seeds, to choose full and complete and the latest years, such seeds germination success rate is higher. If the temperature is high in autumn, the germination rate of seeds will be slower than that in spring. At this time, seeds can be treated to make them germinate more quickly.

Treatment method: Rub the seeds before planting, then soak them in warm water for about 12 hours, wash off the mucus on the fennel seeds, wrap them with gauze, put them in an environment of about 20 degrees to germinate, and wait for the seeds to reveal white buds. When choosing to sprout, choose the long and fast ones. There are very few seeds that have not sprouted yet. Continue to wait for germination and keep them for later use.

2, soil fertilizer base fertilizer

Fennel is grown on loose, fertile sandy soil, which allows fennel to flourish. Fennel has a requirement for soil fertility, so be sure to apply enough base fertilizer to the soil you are planting. Can be used with manure and ternary compound fertilizer mixture, nutrition is more comprehensive, can effectively improve the quality of the soil, so that fennel more effective growth.

3. Sowing

After applying base fertilizer, be sure to pay attention to deep ploughing of the land, do not exist large soil, which will make the soil fertilizer uneven, so after ploughing the soil, level the bed, and then sow the germinated fennel seeds, and cover a thin layer of soil after sowing. But be aware that in autumn there will be a lot of rain, so make high beds and cover the heavy fennel seedlings with film to protect them from being washed away by rain.

4. Thinning and supplementary seedlings

When fennel breaks ground and sprouts, when true leaves appear, you can start thinning seedlings. First remove the surrounding weeds and then plant spacing about 4 cm to start thinning, if there are fennel seedlings scarce places to timely supplement seedlings.

5. Fertilization

Fertilize fennel seedlings when they are about seven to eight centimeters tall, because fennel requires a lot of fertilizer to grow quickly. Urea can be combined with water and can be used about 10 kg per mu. When the fennel seedlings grow to ten centimeters, they can continue to use urea for a second time to accelerate the growth of fennel. When compound fertilizer and urea are used together, eight true leaves appear in fennel seedlings, and the quality of fennel grown at this time can reach a certain level.

When fennel grows to two or four leaves, foliar fertilizer is used to promote greening and growth of the leaves. In order to prevent the fennel from lodging during its growth, some drugs should be used to control the growth of fennel when it grows to a certain height.

6. Timely harvest

Fennel can be harvested once or several times. If the fennel yield is higher, it can be harvested several times, and the harvested fennel plants can grow to about 30 cm, but it should be noted that the way to harvest fennel many times is to cut it three or four cm away from the ground, and then apply fertilizer to promote growth, and one harvest can be directly uprooted.
