Morphological characteristics of fennel

Fennel is a perennial herb, 40-200 cm tall, whole plant surface with powder frost, glabrous, with strong aroma. Stem of Fennel is erect, smooth, grayish green or pale, branched.3-4 pinnately compound leaves, final leaflets linear, 4 -- 40 mm long, ca. 0.5 mm wide; Petiole ca. is 14 cm long, base sheathlike operculate.Inflorescence terminal complex umbel; Total pedicels of Fennel are 4 -- 25 cm long, involucre and bracteoles absent; Umbrella spokes 8 ~ 20, unequal in length; The flowers are small and yellow; Calyx teeth; Petals 45, broadly ovate, upper part inward curled, concave; Fennel has 5 stamens=, longer than petals;Ovary is inferior, 2-loculed, style 2. And hanging Fruit oblong, with 5 ridges. Inflorescences of Fennel are 1 -- 2 cm in diameter, white or bluish-white, with 5 -- 7 single flowers, diploid fruit oblong-ovate, 5 -- 8 mm long and 2 -- 3 mm wide, containing two yellowish seeds. 

Distribution range of fennel

Country of origin: Zhonghai region. Each province of our country has cultivated. 

Fennel growing method

Fennel planting soil should be loose and fertile, and the best is sandy soil, which will make Fennel more productive, especially the best planting Fennel soil to keep between acid six. To plough the soil, plough the soil to a depth of 20 centimeters. And in the soil mixed with compound fertilizer or farmyard fertilizer and to add 40 kilograms of phosphate fertilizer, potassium fertilizer 15 kilograms, this will make the soil more fertile.

In particular, farm manure can be farmed with their own pig manure, sheep manure, cow manure, chicken manure, these feces after processing, can be in the summer of every year after exposure to the sun for disinfection, so that feces and soil mixed, will become a very nutritious fertilizer. Fennel's great for growing vegetables, and it's important to get rid of all the rocks and dirt in the soil. The soil for Fennel should become delicate and loose, so that the soil is very suitable for the growth of Fennel. Especially in the soil, you can combine some quicklime, or you can spray potassium permanganate to disinfect the soil, so that the soil is more clean and suitable for Fennel growth.

Sow the seeds

Fennel varieties are more, to choose suitable for the local temperature environment to plant seeds. And choose varieties that are resistant to disease and have high yields. Choose a Fennel variety that can be soaked in water to promote germination, and the temperature is kept at about 25 degrees Celsius, so that the seeds can germinate. The seeds for Fennel are sown directly in the soil. Dig a small trench five centimeters deep in the soil, spread the seeds in the soil, and then cover with two centimeters of soil, and then you can water. Keep the soil moist so the seeds can germinate. And wait until the seedlings of Fennel grow to five or six centimeters high when the seedlings can be set. In particular, pull ditch can not be too deep, otherwise it will make it difficult for seeds to germinate. And the soil cover should not be too thick, there are 1 to 2 centimeters can be, otherwise cover too thick will affect the nutrition of the seed germination.

Seedbeds can also be selected for Fennel seedlings, seedlings can be transplanted later. Transplanted seedlings had better be transplanted with soil, so the survival rate is higher. Basically, the spacing between the plants should be about two centimeters. And when raising seedlings of Fennel, if the temperature is low, plastic bubble film can be covered to increase the temperature. You can also use a Shovel to dig the nest, the seeds in the nest, so that each nest can sow two or three seeds, and then wait until the seedlings grow up, thinning, seedlings this method, can also be planted Fennel.

Field management

When managing in the field, we must weed the poplar seedlings. Removing weeds allows the seedlings of Fennel to be ventilated and grow more vigorously. And weeds are also a major source of disease and insect pests of Fennel. Be sure to clear the weeds and throw them out of the ground.Wait until dry and then incinerate. Otherwise, the seeds of the weed will survive and grow again next year. And weeds multiply very quickly and absorb more nutrients. So weeding out weeds is imperative.

And in the management of the time to check the growth of Fennel seedlings, if there is a poor growth and inflammation of seedlings to be removed in time, otherwise it will bring bacteria and diseases, affecting the growth of other seedlings. You can replace more vigorous seedlings and make sure that the seedlings in the field grow in order to keep healthy. In the process of management, it is necessary to check whether the seedlings of Fennel have diseases and insect pests in time. If there are diseases and pests, be sure to treat them in time. This will allow the seedlings to grow and increase the yield.

It is recommended that when the Fennel grows to the middle stage, fertilizing and watering the Fennel should be given. During the Fennel growth process, fertilizer is basically applied three times, and the amount of fertilizer can be gradually increased each time. And the amount of water depends on how wet the field is. If it is the rainy season geographical comparison to reduce watering, otherwise it will let the seedlings appear rot caused by death, the impact of production. Basically Fennel to about a foot long, green seedlings are particularly good-looking, this time can be harvested. Spray water before harvest to keep the ground moist, which is more conducive to harvest, and pluck directly into bundles to sell.
