The effect of chicory field on the culture method of chicory

Chicory is a kind of medicinal and edible plant, which has high nutritional value and medicinal value. If you have a big balcony or a courtyard at home, you might as well consider planting some chicory, which is not only edible, but also has a pretty little blue flower. Today, let's learn about the culture methods and points for attention of chicory.

I. the efficacy and function of chicory

1. Chicory is a variety domesticated from wild chicory with tender leaves, leaf balls and leaf buds as vegetables. it is native to the Mediterranean, central and northern Asia. Chicory contains some bitter substances that are not found in common vegetables, such as chestnut glucoside, chestnut bark glucoside, mountain lettuce and mountain lettuce, which have the effect of clearing liver and promoting gallbladder.

2. The extract of wild chicory flower injected into animals can excite the central nervous system and enhance cardiac activity (amplitude increases but frequency slows down) the decoction has antibacterial and convergent effects. Root can increase appetite and improve digestive function; high concentration of extract can increase gastric secretion, but does not increase smooth muscle tension. The ethanol or ether extract of root has antibacterial activity, and its active component may be a sesquiterpene. The root also has the effect of light diarrhea. The seeds have hemagglutinin from non-specific resident plants. There are also reports of carcinogenic hydrocarbons in chicory. Its content is higher than that of other coffee drinks.

3, the function of chicory: heat-clearing and detoxification, diuresis and detumescence. Main damp-heat jaundice; glomerulonephritis edema; epigastric distension pain; appetite activation.

4. Chicory is rich in potassium, which can effectively increase the oxygen supply to the brain and regulate heart rhythm.

Second, the culture method of chicory

1. Soil culture methods of chicory.

Site selection: select the sandy loam with deep soil layer, loose and fertile soil, fine crushed soil and good air permeability, and the planting area should be convenient for drainage and irrigation.

Temperature: chicory is a semi-cold-tolerant plant, and the taproot has a strong cold resistance. The optimum temperature for plant growth was 17-20 ℃, and when the temperature exceeded 20 ℃, the assimilation capacity decreased. However, the plants in the seedling stage had strong high temperature tolerance, and the optimum temperature for growth was 20-25 ℃. In the period of promoting the cultivation and softening of chicory, 18 ℃ was the best. The bud ball formed by too high temperature is loose and not compact; if the temperature is too low, the bud ball can not be formed for a long time.

Moisture: chicory needs a moist environment throughout its growth and development. If the soil moisture is insufficient after sowing, the time of germination and emergence will be delayed. But in the seedling stage, in order to promote the development of root system, it is necessary to properly control moisture so as to see wet and dry. After the plant grows, the taproot begins to expand, and the supply of water should be ensured.

Illumination: sufficient light is needed during the vegetative growth period of the plant so that the fleshy root can grow fully. Dark conditions are needed to facilitate cultivation.

2. the method of hydroponic culture of chicory.

The principle is basically the same as that of soil culture, and it can carry out three-dimensional production and mechanical operation, and the production efficiency is higher.

Using the water culture method, the root plant must be washed clean and a small part of the root tip of the fleshy root must be removed, which can promote the growth of the bud ball, make the bud ball more compact and thicker, and have better commercial quality. The water quality should be clean to prevent root soft rot in the process of hydroponic culture. it is best to use flowing water or change water frequently. It is more appropriate for the water level to be below 1pm 2 and 1pm 3 of the fleshy root, and the temperature, humidity and shading should be strictly controlled, especially the temperature should not be higher than 20 ℃. If the temperature is higher than 20 ℃, with the temperature and increase, the weight of the bud ball decreases and the divergence rate increases sharply. The relative humidity of the air in the culture bed should be kept above 95%. The bud balls formed under low humidity conditions are loose, light in weight and fiber, and taste poor when eating. At the same time, because the upper part of the fleshy root is not covered, the bud ball greening will occur in 1-2 hours under weak natural light and weak light. After more than 5 hours, the outer and inner leaves of the bud ball will obviously turn green, and the quality will decline, so the operation should be fast. In order to reduce the time of seeing light indoors as much as possible.
