Cultivation techniques of Centella asiatica

Centella asiatica, also known as Centella asiatica, etc., is widely distributed in many provinces and regions in China. Centella asiatica has high medicinal value, with the effects of clearing heat and dampness, detumescence and detoxification, and is now widely developed into artificial planting of cash crops. So, what are the cultivation techniques of Centella asiatica? Let's study together.

1. Soil

The selection of good soil is a prerequisite for planting. Centella asiatica has strong environmental adaptability and lax requirements for soil. it is appropriate to choose soft and well-drained soil, and it is best to choose loose and fertile humus soil. this kind of humus soil has good drainage and air permeability, high fertilizer and sufficient nutrients, which can supply all kinds of nutrients needed for the growth of Centella asiatica, and can also allocate the cultivated soil by itself. Rotten leaves, river mud and garden soil can be mixed and mixed according to 0.5 _ (2) _ () _ (2).

Second, temperature and light

Centella asiatica likes a warm and humid environment, strong shade tolerance, can not be exposed to direct sunlight, the direct sun temperature is too high will burn leaves, but also need appropriate amount of light, when the light is insufficient, it will cause its roots to rot, so it is best to put it in a semi-overcast and semi-sunny environment, to maintain 4-6 hours of light every day, which is beneficial to its growth. In terms of temperature, the suitable temperature of Centella asiatica is 10-25 degrees, which should not exceed 32 degrees in summer. The temperature should not be lower than 5 degrees in winter.

Third, moisture

Centella asiatica is a kind of wet, so it must be watered frequently to keep the soil moist and promote its growth, but it should not be watered too much. it is necessary to control the amount of watering, watering too much, resulting in soil stagnant water. it may cause damage to its roots and is easy to breed diseases, so we can take the method of watering a small amount frequently to control the soil water management.

IV. Fertilization

The growth process of Centella asiatica needs a lot of nutrients, so appropriate fertilization is needed during cultivation, especially after entering the growing season, its growth is very exuberant, and the demand for fertilizer is high, with an average of about 2 times a month. It should be noted that the concentration of fertilizer should not be too strong, so it is recommended to dilute the fertilizer with water, which can avoid damage to the root system caused by thick fertilizer. It can also improve the utilization rate of fertilizer and save fertilizer.

Prevention and control of diseases and insect pests

Centella asiatica is easy to raise, with few diseases and insect pests, and sometimes leaves turn yellow, mainly due to lack of water, frostbite of roots, poor air circulation in the room or heavy leaf dust affecting photosynthesis. At this time, compound fertilizer based on nitrogen fertilizer can be sprayed. Attention should be paid to changing water frequently and paying attention to root hygiene.

The above is the cultivation technology of Centella asiatica collected by Xiaobian for you. In addition to being used in Chinese herbal medicine, Centella asiatica is also widely used in the production of skin care products with broad market prospects and rich economic benefits. those who have the conditions to invest can be considered according to their own conditions.
