What is chicory: chicory is a perennial herb of Compositae, which can be used as medicine and food

When it comes to chicory, it may be strange, and even some people have never heard of it, just like Xiao Bian, who is a scum of learning, has never heard of it and met it. I believe many people, like Xiaobian, don't know much about chicory. So what is this mysterious plant? Let's get to know it with Xiaobian!

What is Cichorium intybus L., a perennial herb of Cichorium intybus L. The root is fleshy and short. Stem erect, angulate, hollow, much branched. Leaves alternate, long oblanceolate, head inflorescence, corolla ligulate, blue flowers.

Chicory is a dual-purpose plant for medicine and food. Its leaves can be used to make lettuce, and its roots contain inulin and aromatic substances. It can be used to make alternative coffee and promote the activities of human digestive organs. The above ground parts and roots of plants can be used for medicine. The traditional Chinese medicine names are chicory and chicory root, which have the effects of clearing away heat and toxin, diuresis and detumescence, and strengthening stomach. Chicory is a perennial herb with a height of 40-100 cm. Stem erect, solitary, branches spreading or extremely spreading, all stems and branches green, ribbed, covered by very sparse long leaves

Bristles or setae curved or almost glabrous. The basal leaves are rosette shaped, living at flowering stage, oblong and oblong, including petioles gradually narrowed at the base, 15-34 cm in total length and 2-4 cm in width, with petioles gradually narrowed at the base, big head shaped, inverted, pinnate or undivided, with sparse sharp serrations at the edge, 3-6 pairs or more lateral lobes, larger apical lobes, smaller downward lobes, all lateral lobes falcate or irregular Sickle shaped or triangular. Cauline leaves few, smaller, ovate oblanceolate to lanceolate, sessile, base rounded or halberd, enlarged, semiamplexicaul. All leaves are thin in texture, with sparse multicellular long nodal hairs on both sides, but more hairs on the veins and edges.

There are many head like inflorescences, which are solitary or several, gathered at the top of the stem or the end of the branch, or 2-8 in a group, arranged into a spike along the flower branch. Involucre cylindric, 8-12 mm long; involucre 2-layered, outer layer lanceolate, 8-13 mm long, 2-2.5 mm wide, upper part green, herbaceous, margin with long cilia, abaxial surface with very sparse long glandular hairs or simple hairs capitate and stipitate, lower part yellowish white, hard, leathery; inner involucre linear lanceolate, 1.2 cm long, 2 mm wide, lower part slightly hard, upper part slightly leathery Margin and abaxial surface usually with very sparse long glandular hairs capitate stipitate and mixed with long simple hairs.

Ligulate floret blue, ca. 14 mm long, variegated. Achene obovate, elliptic or cuneate, outer achene compressed, close to inner involucre, 3-5-ribbed, top truncate, narrowed down, brown, with brown black spots. Corolla very short, 2-3-layered, membranous, 0.2-0.3 mm long. The flowering and fruiting period is from May to October.

The growth environment and distribution of Cichorium intybus flowers are mostly in coastal wasteland, riverside, ditch or hillside.

China is mainly distributed in Beijing (Baihuashan), Heilongjiang (Raohe), Liaoning (Dalian), Shanxi (Fenyang), Shaanxi (Xi'an, Meixian, Zhouzhi), Xinjiang (Altay, Habahe, Urumqi, Chabuchar), Jiangxi (Suichuan), etc.

It is widely distributed in Europe, Asia and North Africa.

Breeding methods of chicory 1. Seed treatment

7-10 days before sowing, put the seeds in a cool and ventilated place for 1-2 days to improve the germination rate, but do not expose them to the sun on the cement floor. In order to ensure the whole seedling, the germination rate should be determined before sowing. Generally, imported chicory seeds are treated with fungicides and can be dry sown (seeds with red or green color are treated with pesticides and washed with soap after hand contact). If the seeds are self collected or bred in China, the seeds can be soaked in cold water to remove the floating seeds. After the sinking full seeds come out of water, they can be sown after the water is removed.

2. Sowing

(1) Live broadcast

Chicory is suitable for direct seeding. Direct seeding method is ridging cultivation, equal row spacing of 40 cm, sowing at the top of the ridge. Double ridge sowing can be carried out in large and small rows with a spacing of 30cm. First, draw a small ditch 0.5cm deep with a bamboo pole. Hold the seeds in your hands, twist the seeds into the ditch with two fingers, and gently level them with a hoe.

Water immediately after sowing, do not cross the ridge, do not overflow the top. Water before emergence, then water after emergence. The first thinning of Cichorium intybus with 2-3 leaves and the second thinning of Cichorium intybus with 4-5 leaves were carried out. When the leaves are 7-9, the plant spacing is 17 cm for single row sowing and 19 cm for double row sowing, with 8500-10000 seedlings per mu.

(2) Seedling raising

Seedling facilities can be small nutrient soil or plug seedling. The 288 hole seedling tray is selected to raise seedlings, which can not scatter lumps and damage roots, and has high survival rate.

Medium for seedling. If conditions permit, 2 parts of peat, 1 part of vermiculite, or 1 part of peat, waste mushroom and vermiculite can be mixed. If 288 hole seedling trays are used, 40-50 seedling trays are needed for planting 1 mu of chicory, and 300 trays can be loaded per cubic meter of substrate. When preparing the substrate, 0.7 kg of compound fertilizer is added to each cubic meter of substrate, or 0.5 kg of urea and 0.5 kg of potassium dihydrogen phosphate are mixed with the substrate and filled into the hole tray for standby.

3. Transplanting management

The water should be permeable when planting, and the slow seedling water should be poured once 4-5 days after planting, and then the water should be watered according to the soil moisture. In the later stage of rosette, the root plants enter the expansion stage. Topdressing with urea is 10 kg per mu, 1-2 times, and the topdressing should be combined with watering. In order to control the growth of the above ground part and promote the expansion of the root, it is necessary to plough and weed 1-2 times in time after planting or seedling setting.

The main value uses of Chicory in greenhouse 1. Garden use

It can be used as material for wild garden or mixed planting in sparse forest.

2. Medicinal value

Efficacy indications

Clearing away heat and toxin; diuresis and detumescence. Indications: Damp heat jaundice; nephritis edema; epigastric pain; loss of appetite.

It also has the effect of strengthening the stomach.

3. Edible value

Chicory leaf can make lettuce, root contains inulin and aromatic substances, can make alternative coffee, promote the activities of human digestive organs.
